Grundos a leader in the field of water pumps has got into solar pumps.Check the site below
http://www.nairaland.com/1245354/grundfos-solar-water-pumps
In 2010, more water – 583 billion cubic metres – than is discharged each year by the mighty Ganges River in India was used to meet the world’s growing energy needs.
It’s an interesting statistic, but why should that matter? Well, if the world continues on its merry way, power capacity – particularly with water-hungry energy technologies such as coal and nuclear – and water-dependent extractive techniques such as coal, shale gas and tar sands, are going to grow quickly, and, according to the International Energy Agency, the world’s demand for water will grow at twice the pace, putting pressure on increasingly scarce water resources.
In countries such as India and China which are already experiencing water stress, power demands will grow 70 per cent over the next 20 years. Most of their water is reserved for agricultural and municipal needs. Both countries, like many others in the developing world, are water stressed, and neither can afford to replicate the US, where nearly half of the water consumption is reserved for energy use – biofuels, coal mining, gas extraction, and generation.
The pressure is so great that the IEA has, for the first time, dedicated a whole chapter of its annual reference work, the World Energy Outlook, to the issue of water scarcity and energy supply. It says water is going to become an “increasingly serious” issue for unconventional gas development and power generation in parts of China and the US, and for the growing fleet of water-dependent power plants in India, and the oil sands production in Canada.
It seems to serve as a warning to those that wish to invest in energy projects. As a general rule – with the exception of water-hungry nuclear – the more emissions intensive the energy type, the more water it needs. The politics of climate change may mean that no limits on carbon emissions are imposed to restrain the development of these technologies, but nature may impose its own restraint through the access to water. And, as the IEA notes, a surging population, a growing economy and heightening climate change impacts will further impact on energy reliability and costs.
It might be the first time that the IEA has addressed the issue of water stress and its impact on the electricity sector, but private analysts have been watching the issue carefully for some time.
In September, HSBC Bank issued a report, entitled No water, no power, that looked at the challenges facing China and its electricity demand, highlighting the fact that its most coal-rich and industrialised provinces faced the most critical water shortages, and the ambitious expansion plans for power capacity faced real constraints. “There is a mismatch between water capacity and planned capacity additions,” it noted.
The HSBC report said that some 47 per cent of China’s coal reserves are located in provinces where water is scarce (see graph), and HSBC thinks there may not be enough water to extract it. “Coal requires water to extract, transport, process (wash), store and dispose. We think water scarcity is another reason for authorities to reduce reliance on fossil fuels,” they wrote. “Without a vast improvement in the water efficiency of power capacity, some power plants potentially run the risk of becoming stranded assets.”
The Chinese administration is obviously aware of the challenges. “We should launch a revolution in energy production and consumption, impose a ceiling on total energy consumption,” the outgoing leader Hu Jintao told the party congress this week.
The IEA picks up on a similar theme. It notes that energy efficiency and wind energy and solar PV are the energy options with the lowest water requirements (see table below), and in its 450 scenario – where the world acts boldly to limit global warming – the deployment of these technologies means that water use grows only marginally over the coming decades.
In its business-as-usual and its “lip service” scenarios – where governments do a little bit on climate but not terribly much – water demands grow exponentially.
However, apart its focus on energy efficiency and renewables such as solar PV and wind, the IEA’s mainstream 450 Scenario also requires technologies – including nuclear power, CCS-fitted power plants and conventional biofuels – whose high water-use requirements must be taken into account. All of these technologies can find ways of using less water, but to do so adds to operating and capital costs, and can make the plants less efficient in some instances. Solar thermal – or concentrated solar power – which uses the sun’s heat (instead of coal) to boil water – is also water hungry.
The HSBC report notes that three provinces – Shanxi, Shaanxi, Inner Mongolia and Xinjiang – hold 74 per cent of China’s total coal resources, but only 7 per cent of the nation’s water resources. This could limit the scope to build power plants in those areas, forcing more coal to be transported to demand centres, adding to capacity bottlenecks – the infamous 110km traffic jam in China in 2010 was caused by more than 10,000 trucks carrying coal supplies from Inner Mongolia. Water shortages in those areas have already caused the cancellation of dozens of water intensive coal-to-liquids projects.
In nuclear power, while all of China’s existing plants use seawater for cooling, future plans include the development of inland nuclear power facilities – three are due to start construction during the course of the 12th Five-Year Plan – that will add to competition for scarce water resources where the plants are sited.
The IEA notes that India is facing similar problems. Summer water shortages in 2010 caused the 2.3GW Chandrapur coal-fired power station in Maharashtra to shut down, leading to power outages across the state. The plant again faced water shortages, due to the delayed monsoon, in mid-2012, and water shortages in northern India have at times reduced hydropower generation, exacerbating power shortages due to insufficient coal supply to power plants.
In the US, the IEA notes, concerns about water availability and the effect of production on water quality could also significantly slow the development of shale gas production – particularly in water-poor states such as Texas.
“There is no doubt that water is growing in importance as a criterion for assessing the physical, economic and environmental viability of energy projects,” the IEA notes.
The Agency says there are several options to address this: one is a greater reliance on renewable energy technologies that have minimal water requirements, such as solar PV and wind; another is to improve the efficiency of plants, and another is to deploy more advanced cooling systems. (The CSIRO is working on one technology that uses minimal amounts of water for solar thermal plants).

* A solar power unit is producing entire electricity needed for pumping water to raise three crops a year in 13 acres in Katrayanapadu village limits in Musunuru Mandal of Krishna District for the past three years. The 51 solar panels of the unit with a photovoltaic system rating of 10 kilowatts produce enough power to run a 12.5 horse power (HP) motor all through the day.

A successful pilot project launched here has come to fruition and the Schneider Electric proposes to go commercial with its solar variable-frequency drive (VFD) which can run a 3-phase AC motor directly with the power generated by the panels. When sky is overcast the motor works at lesser frequency, but still draws water.
Earlier, DC (direct current) motors had to be used for solar power units because the photovoltaic (PV) cells produce DC current. Since the power produced by the PV cells fluctuates with the intensity of the sunshine, it had to be used to charge batteries first and then the batteries used to run the DC motors. This VFD devise allows use of the solar power for running the existing AC electric motors on fields. Sunbright Energy Solutions Private Limited came up with the idea of using a VFD to use solar power. Company CEO Parvataneni Ramesh toldThe Hindu that the unit has been working so well that representatives of Schneider Electric that custom built the VFD for them came here to assess the performance.
The success of the unit at this village encouraged them to install yet another unit at a 22-acre sweet lime garden in Chatrai mandal. Company vice-president Vikas Jaivanth said that solar energy was clean power that is gaining tremendous importance in the fast emerging global warming scenario.
He said the Central government was giving 30 per cent subsidy on such products, but producing the necessary documentation was currently highly cumbersome. Schneider Electric managing marketing (Motion and Drives) Prabhu S. Nagavi said that the company had put the VFDs on trial in different climatic conditions and would launch it commercial on their completion. source 12/9/12
* Solar water pumps, India
Solar radiation over India is 5000 trillion KWH/year; it has 300 sunny days in a year. India must definitely make use of this. Cost effective solar power can be the answer for all our energy needs. Solar powered water pumps are the answer to the Indian farmer.
A solar powered pump can be more environmentally friendly and economical in its operation compared to pumps powered by an internal combustion engine (ICE) or nuclear power. For irrigation and drinking water solar PV water pumping systems are used in India.
This solar water pumps blog is of interest.To the water hungry farmer reeling under the high cost of diesel on one hand and frequent power outage on the other.
To the manufacturers of solar powered water pumps, To the suppliers of solar water pumps, To all nodal agencies working for the benefit of farmers of India
The blog tells the farmer where to buy his solar pump, the costs of different suppliers and the kinds of solar powered pumps available in the market. The makers of water pumps powered by the sun can study the competitive market, steps taken by concerned state governments in handling farmers� grievances. Businessmen from India can see a huge market opening in India. Areva the French energy company is to invest $3 billion in solar power sector. Obama has promised $300 million in clean energy Investment fund.
How a solar water pumping system works:
Solar water pumping system works on power generated using solar photovoltaic system. The solar energy is converted in to electricity by using a photo voltaic array. This electricity is used for running the motor pump set. The pumping system can draw water from bore well, open well, pond, stream etc.
Usually 200 watt � 3000 watt motors are used in water pumps and these motors are powered with 1,800Wp PV array which can bear about 140,000 litres of water/day from a total head of 10 meters.
There are basically 2 types of solar water pumps, which are positive displacement and centrifugal solar pumps. These are again classified in to submersible pumps, surface pumps and circulating pumps.
Requirements for solar water pumps:
Solar pumps require no fuel and little or no maintenance. This system needs a shadow � free area for installing the solar panel.
Utility:
A system having PV array capacity of 1800 watt and 2HP pump can discharge about 1.4 lakh litres of water per day from a depth of 6-7 meters. This amount water can be used for irrigation of about 5 -8 acres of land holding for several crops.
Approximate cost:
Total cost for installation and commissioning of SPV water pump system varies from 1, 90,000 to 2,90,000. Government of India provides subsidy to solar water pumps through MNRE (1, 80, 000). The overall cost (upfront, operating, maintenance, replacement) of a diesel pump is 2 to 4 times greater than a solar pump.
Advantages of solar water pumps:
- Clean and efficient
- Electricity is not required
- No fuel cost
- Low labor and maintenance cost
- Highly reliable
- Durable
- Eco � friendly
- Long operating life ( Usually 20 to 40 years)
- Easy to remove, transport and store
- Non polluting
- No need of complicated wiring
- Simple to install
Benefits of Solar water pumps:
Solar water pumps are used for irrigation of crops, water livestock and provide portable drinking water. Solar water pump uses peak solar array output which frequently coincides with high water demand during long, dry summer days. In the event of cloudy weather solar water pump systems often use storage tanks to store excess water. Solar water pumps do not require fuel or constant maintenance. Solar water pumps can also be designed for portability to be moved as water demand or change of season requires. Their operating cost is less compared to diesel pumps.
Due to large range of power of the pumps and the availability of water when it is needed, diesel water pumping is more attractive. It can pump water for varying daily demands through longer operating periods (assuming sufficient borehole strength), thus allowing for the flexibility required in some applications. The technology is well understood and service for diesel engines is readily available. Recent fuel price increases and generally intensive maintenance schedules however can make diesel pumps expensive.
Improved solar water pumps:
Solar water pumps have come a long way in 25 years and today there are solar pumps on the market which have improved on previous technology.
Features of improved solar water pumps:
� Good quality and reliability
� Pumps are able to pump large amount of water
� Submersible pumps can pump up to 200m heads
� Pumps can pump larger volumes of water
� Low maintenance requirements
� Good performance which means fewer solar panels to pump same amount of water
� Some of the pump models can be backed-up by a genset to pump additional water with the same pump during the night or during overcast days
How solar powered pumps score over diesel pumps:
� Simple to install
� Solar pumps are �good� for bore holes as they pump over the whole day
� Weak boreholes can be used effectively with a low volume pump due to pumping 8 to 10 hours a day
� Require minimal attention since they are self starting
� To increase daily water pumping rates, tracking arrays can be used
� Environment friendly
� Solar pumps offer clean solutions with no danger of borehole contamination
Solar Water pumps have come to the rescue of Punjab farmers. Punjab is a land of 5 rivers and there is no dearth of water, but lack of adequate power to pump out the water was a great hindrance for the farmers.
Tata BP Solar water pumps:
Tata BP solar stepped in at the request of Punjab Energy Development Agency and provided the farmers with 2HP DC surface pumps powered by the sun. The Punjab Energy Development Agency, offered the pumping system to farmers at an end � user contribution of just Rs.35000/-. The solar water pumps were a runaway success from day one.
CTRADE solar water pumps:
CTRADE is another player in water pumps powered by the sun. Rural Karnataka has benefitted from these solar water pumps. The advantage of this solar powered water pump is that it will pump water at the rate of about 2 gallons per minute for about 8 hours during the day when the sun is shining on the solar panels and pump water into an above ground water storage tank. These pumps can be installed below the water level in a pond, river or cistern, or installed by hand into a ground water well. They can be used to fill an open tank or in pressurized water delivery systems. Simplicity is the key feature of these pumps. They are easy to install, require very little maintenance and are repairable.
Village Solar Well Water Pumps
CTRADE will install small Solar Well Water Pumps which are
highly efficient, low voltage, DC powered, diaphragm type
positive displacement pumps designed specifically for water
delivery in remote locations. They operate on 30 volts using
80 Watt solar panels. The system will pump on average about
700 gallons per day at 100 feet of TDH.
CTRADE designed system is especially suitable for rural
applications in India, where the cost of electricity is very high
and not reliable. These pump systems are reliable for at least
5 years of operation. Imagine replacing all electric driven rural
pumps in India, requiring no more electric power for water.
The advantage of this solar powered water pump is that it will
pump water at the rate of about 2 gallons per minute for
about 8 hours during the day when the sun is shining on the

little maintenance and are repairable.
C TRADE will install the systems, in villages in India with the
collaboration of the Karnataka Renewable Energy
Development. The cost of the complete system is about
$2,000 (Rs.80,000) each. C TRADE in partnership with Secon
will assemble and later manufacture the solar water pumps at
its facilities in Bangalore, India.

NEDA solar water pump:
UP farmers were suffering from drought and frequent power cuts left the bore well inaccessible. Nonconventional Energy Development Agency provided them with solar based water pumps which were power cut proof.
One of the unique feature of these environment-friendly pumps is that they are more powerful than the diesel ones and can pump out water from as deep as 200 feet and up to 12 hours at a stretch. NEDA has successfully installed two such pumps in rocky terrain of Sonebhadra district.
Costing about Rs 3 lakh, these portable solar water pumps can be taken anywhere and its solar panels are maintenance � free for about 20 years. The centre has already sanctioned Rs 12 crore for the scheme. At the moment, the state is charging about Rs 70,000 from the beneficiaries. Selection process to choose applicants for SPV pumps based on land holding, and water table. By 30 September 2006, a total of 7,068 solar PV water pumping systems have been installed.
We can take these steps to promote SPV pumps:
� Create awareness of the product and benefits
� Build strong distribution and service network
� Reduce subsidy offered for conventional energy
New initiatives by MNRE:
Committee formed to draw a road map on SPV in 2005
Bulk procurement of silicon wafers
Increased manufacturing centres of wafers
R&D in to reduced usage of silicon wafers
What�s next?
� Incentivise solar power usage
� Technology upgradation and large scale volume production for silicon/wafers through foreign direct investment
� Permit multiple use of system
� Facilitate micro-financing through rural banks/NGOs financial intermediaries
� Facilitate focus on quality and standardized training � institution accredition / networking
� Locate low cost finance. Working capital at low interest.
� Tax holiday for solar industry
� Explore support through CDM revenue

Nice blog Aathmika !
I am interested in knowing
a. market size in India in the urban and rural dividesb. any new models that are being used in developed countriesc. any big brands in the market
Ofcourse, I am not asking you Aathmika.You have already done a lot of work.
If there is someone in the field of solar water pumps and wouldnt mind sharing info, they are welcome.
Hi Aathmika!
We have been trying to source both DC surface and submersible pumps for the past year. The account you give is great. Please can you give further information regarding sourcing the pumps. We have considered various companies in India, Belgium (Grundfos) Germany (Lorentz) and US (Surflo); but the solution you talk about sounds the best so far. We have 6 x 220 W solar panels and urgently need a pump. Thank you for any suggestions.
Resp. Madam,
Nice blog about solar pump, As you know in Maharashtra, its cost Rs. 1.75 lacs to 2.75 lacs
as I have inquired. But As you stated, if we get dc motor supplier source , its cost becomes very low, & which can be feasible & viable for farmers in Maharashtra.
Concerned about prolonged power cuts in urban areas, the state drinking water and sanitation department (DWSD) has decided to use solar energy to run its pumps during power cuts.
The solar panel will be installed at the site where pumps are installed; the problem of disturbance in transmission will also be tackled. Once the pilot project is successful, the department plans to install solar power-operated pumps in all the anganwadi Kendras. There are around 38,400 anganwadis in the state. Chief engineer S Narayan said, "The department has invited companies with expertise of manufacturing and operating solar energy-driven pumps to run pilot projects at select locations for a month." Narayan added that if the cost is competitive, then the department will switch over to the new technology.

Solar Water pumping is promoted in some countries. For example in India Solar Water pumping is given heavy subsidy.There are SPV Pumps 7,495 nos up to 30-9-2010 (Source:MNRE).
But generally the Solar Pumps are useful to pump water from less than 10m depth effectively. Assuming that dry lands require water, solar pumps are useless. Moreover in India in many states Power for agriculture is almost free. In Andhra Pradesh those owning less than 2 and half acres wet land or 5 acres dry land need to pay Rs 30 per month (0.75US$).
The Solar pumps are not at all useful as a reliable source of power for water supply as sunshine is intermittent. In areas where water table is high, then solar pumps may find use as can be seen from dismal picture of solar pumps in India. There are an estimated 12 million Electric Pump sets and 6 million diesel pump sets in India.
Because of heavy subsidy only even 7,495 solar pumps are installed otherwise not so.
This only shows Subsidies alone won't drive a Renewable Energy power but utility and reliability is.

I have First hand information of SOLAR PUMP from the installation one one Solar Pump in our Institute.
Some of your statements are not true:
The overall cost (upfront, operating, maintenance, replacement) of a diesel pump is 2 to 4 times greater than a solar pump.
It is not at all the case. Diesel pumpsets deliver water on a sustained basis so long as water is there. Solar pumps peak water pumping capacity a few hours of sunshine in a day.
One of the unique feature of these environment-friendly pumps is that they are more powerful than the diesel ones and can pump out water from as deep as 200 feet and up to 12 hours at a stretch.
This is a sweeping statement. People will be misled by it.200 feet and up to 12 hours a stretch? You can count sunshine to pump reasonable water between 10 am to 3 pm(about 5 hours) that too loose water from tanks or atmost 30 to 40ft depth borewells.
When Power for agriculture of small holdings is almost free,who will invest Rs 3lakhRupees(Whether Government Subsidy or beneficiary's share). Often the promoters of this type of systems only quote the beneficiary's share saying that too can be financed by Banks. Does it mean Subsidy amount comes from air? Subsidies are also People's Public money which should be judiciously used.
A system having PV array capacity of 1800 watt and 2HP pump can discharge about 1.4 lakh litres of water per day from a depth of 6-7 meters. This amount water can be used for irrigation of about 5 -8 acres of land holding for several crops.
5-8 acres of land holding for several crops - Impossible.Meaning less statement.
Usually 200 watt – 3000 watt motors are used in water pumps and these motors are powered with 1,800Wp PV array which can bear about 140,000 litres of water/day from a total head of 10 meters.
140,000 litres of water/day !! Impossible. Per day means 24 hours of sunshine? In our field of 1.5 acres of Wetland from 10 meters depth two 0 3 HP electric motors take 14 hours for watering.
While writing on Renewables that too affecting Farmers as end users not only technology but also social and cultural aspects have to be taken into account. What is published has to be authenhtic but not simply reproduced from other sources. Many a times some people publish articles with selfish interest.
I am a Wind Energy Expert involved in Wind,Solar Thermal,PV and almost all areas since three decades.
Let us promote Renewables that work to the benefit of the people.
Dr.A.Jagadeesh Nellore(AP),India
Wind Energy Expert
E-mail: anumakonda.jagadeesh@gmail.com
Not so fast and furious, Dr Jagadeesh. We have solar water pumps available today that can pump water from bore wells as deep as 500 feet. And in Nellore it self, the daily solar energy available is one of the highest in India and even the world. These data are available from US renewable energy resources (if you do some search on the Web).
Besides, the issue is not limited to wetland irrigation and not limited to Nellore only. If you are using two 3 HP motors and pumping 14 hours a day to irrigate only 1.5 acres, then there are too many holes in the whole set up. Maybe too much water is wasted, maybe the pumps are extremely inefficient, and so on.
Water in the bore wells as well as open wells is recharged slowly which means water could be (should be) pumped slower and over a longer period of time which means a smaller pump (lower hp) and lesser capacity (power) system will suffice. Additionally, construction of a surface water storage tank will help considerably.
Even though the government promised to supply electricity to the farmer, in practice it is not able to. There are severe cuts imposed on the number of hours (a day) electricity is made available. Free electricity doesn't help when there is no supply (or severe shortages). What good is free when it is not even available?
Just because the government promised to supply electricity free to small farmers, it doesn't mean that there is no cost to it. It only means that the government is bearing the cost of that free electricity which amounts to several thousand crores a year. Who is bearing that burden? Worse is that the farmer is unable to irrigate his crops because he cannot get electrical power when needed and that means the crops suffer and the yields go down. The farmer is losing his income considerably.
Since the electricity supplied is "dirty" - wide fluctuations in voltage from 170 to 260 Volts, the pumps burn out and the farmer incurs a regular cost of repairing them running into several thousand a year (averaged), not to mention the down time. Who bears that cost?
Since Solar panels produce direct current (DC) at lower voltage and supply power at stable voltage (regulators used) this burn-out problem doesn't arise saving considerable amount of money to the farmer.
Also, DC pumps need to be half the capacity of diesel pumps (in hp) for the purpose. That means, you only need 1.5 hp DC pump in the place of a 3 hp diesel pump which again saves money.
Additionally, the government is subsidizing heavily the cost of power plants and the fuel (coal, natural gas) needed to generate electricity. Again, this runs into thousands of crores. Not to mention the cost of transporting fuel. The cost of running electric power lines to very farm is high and can be avoided when solar power is used.
Also, the solar power generated at the farm can be used for harvesting, cleaning farm produce, etc when water doesn't need to be pumped.
Yes, I can see the use of the highly efficient wind mills along side solar power to help the situation.

How much water do I need?
That depends on how many people or head of livestock you want to provide water for. The chart below lists some averages that you can use to estimate your daily water demand.
1 gal = 3.8 litres
How much will a solar pumping system cost to water 100 head of cattle?
That depends on your location, water source and time of year usage. One hundred cattle can drink 2,000+ gallons of water per day which can be very cost effective to provide from a shallow source of water (£100') in the summer months. Please fill out our water pumping questionnaire and send it to us and we can put together an itemized system quote for you.
Top
How many different types of solar pumps are there?
There are really only two basic types of solar pumps; positive displacement and centrifugal and these can both be subdivided into surface mount and submersible categories. Your water source will dictate whether you need to use a surface mount or submersible pump while your daily volume requirement and total dynamic head (TDH) will determine if you need a positive displacement pump or centrifugal pump. In general, positive displacement pumps (diaphragm, piston, helical rotor, etc.) are best used where the TDH is high and the daily volume requirement is low. Positive displacement pumps usually require less power to operate than a centrifugal pump and they will produce some water even in cloudy conditions where a centrifugal pump might not. Centrifugal pumps are good in situations where the TDH is low and the daily volume requirement is high. One of the disadvantages of a centrifugal pump is that it has to operate at a high enough rpm to push the water all the way out of the well. If it is cloudy and the solar array is not producing enough power, the pump/motor may be turning but not fast enough to do this. Using a tracker is highly recommended with a centrifugal pump since it increases the solar array's power output over a longer period of time which increases your daily volume of water delivered.
Which pump should I use?
That depends on many factors all of which are addressed in our "Water Pumping Questionnaire". Please fill it out as best you can and fax/e-mail it to us and we will gladly recommend which pumping system will best suit your needs.
What is total dynamic head (TDH)?
Head is measured in feet/meters or psi and it is a term for the distance that a pump has to push the water from your source to your tank. It may seem odd to be able to list head in terms of pressure or distance, but keep in mind that a column of water 2.31' tall produces 1 psi at the bottom of that column so there is a correlation between distance and pressure. The greater the vertical distance is in between the water source and the tank, the harder the pump has to work to get the water there. Static head is the simple measurement from the surface of the water (when the pump is not running) to the tank. Dynamic head takes into account the amount the water level in the well drops when the pump is running plus the friction loss in the discharge pipe run. Total Dynamic Head is the sum of the static head and dynamic head.
Can I "pull" water out of a well with a surface pump?
Yes, but you are limited as to how far you can pull water up. The theoretical maximum is 33' if you were able to pull a perfect vacuum at sea level. However, few pumping systems are setup at sea level and no pump on the market is able to develop a perfect vacuum on its inlet side. A good rule-of-thumb to go by is don't assume that you can reliably pull water out a well where the static water level is lower than 10'.
Can I install a solar pumping system in my 2" cased well?
The smallest submersible solar pump that we have is the 3" diameter Grundfos SQFlex so a 2" casing presents a bit of a challenge. If the water is within 10' of the surface, we may be able to pull the water out with a surface pump. Otherwise you would have to consider using a jack pump which looks and works just like an oil well you see in various parts of the country. These systems are fairly expensive and complex with their sucker rods, cylinders stroke length so give us a call and we can help you design this type of system.
Should I use a tracker or fixed mount for my solar modules?
The answer to this question depends on your application (domestic use or stock watering), the daily volume of water that you need and what time of year you plan to use the pumping system. For most livestock water pumping applications where the highest daily volume of water is usually needed during the summer, a tracker is highly recommended since it can increase your daily water production by as much as 40% as compared to the same array on a fixed mount. In the winter time, a tracker only increases your daily water production by 5-10%. If your daily water volume requirement is low or you are setting a solar pumping system up for winter time use, then a fixed mount structure is probably the best choice. There are several manufacturers of tracking mount structures, but they can all be divided into two categories: active and passive. Active trackers use sensors, actuators and motors to follow the sun from east-to-west while passive trackers use the heat of the sun on two sealed freon containers (one on each side of the tracker connected with a tube) to do the same thing. Passive trackers are simple and reliable, but they aren't as accurate in aiming at the sun as active trackers and they can be blown off course in high winds. On the other hand, active trackers are more trouble prone and more expensive than their passive counterparts. Give us a call if you want to look into trackers in more detail.
Should I use batteries in my pumping system or go solar direct?
DON'T USE BATTERIES! The only reason I would ever consider using batteries in a solar pumping system is if you have a very low volume producing water source (well/spring) and you need to pump as much water out of it as you can each day. Otherwise, there are several reasons to avoid batteries in a pumping system:
- Using batteries in a solar pumping system lowers the efficiency as compared to going solar direct since it usually lowers the operating voltage of the pump which lowers the operating speed and flow rate of the pump.
- Adding batteries to a pumping system costs more money for the batteries themselves plus a required charge controller, battery enclosure and additional disconnects and wiring.
- Batteries require care and maintenance that isn't always possible in a remote location.
- Batteries performance level and expected lifetime are closely connected with the temperatures that they are subjected to. If batteries are undercharged and subjected to freezing temperatures they could be damaged. If batteries are overcharged and subjected to high temperatures their lifetime will be shortened dramatically. Care must be taken to shield batteries in a remote location from temperature extremes.
You're better off all the way around if you simply go with a solar pumping system that is designed to give you all the water you need during the daylight hours without having to resort to using batteries. Store water in a tank instead of energy in a battery! For a livestock watering system or gravity fed domestic application, we recommend that you use a storage tank that can hold a minimum of 3 days worth of water.Top
Can I use a solar pump to pressurize a tank for domestic use?
Maybe. Keep in mind that 1 psi = 2.31 feet of head so pressurizing a tank up to 50 psi adds about 115' of head that the pump must push against so be sure that your pump can handle it. I would not recommend using a diaphragm pump for this application because you run the risk of rupturing the diaphragm if your pressure switch malfunctions. Another reason not to use a solar direct pump to pressurize a tank is that your tank might get low in the early morning or late evening when there isn't enough sunlight for the pump to operate. Pressurizing a tank is best left to a separate booster pump or an AC centrifugal submersible pump running off of your inverter/battery bank, generator or utility power. Better yet, pump to an elevated tank and gravity feed down to your home or wherever you need the water.
Can I use a wind turbine to pump water?
Yes, but how cost effective this will be depends on your location (i.e. average wind speed), the daily volume of water you need and what season(s) of the year you need the water. If you have a very windy site and you are looking to provide water for a winter pasture, then a wind powered pumping system makes sense. In general the available wind power is highest in the winter and a solar array's power output is highest in summer. The two power sources compliment each other very well seasonally so for the best year round pumping system it could very cost effective to setup a hybrid solar/wind pumping system using one of the new Grundfos SQFlex pumps with a Whisper H80 wind turbine. Keep in mind that wind turbines have moving parts which are subject to wear and tear and require maintenance so a wind powered pumping system may not be as reliable as solar.
What size wire and discharge pipe should I use?
The proper size wire to use in between your solar array and/or wind turbine and the pump depends on the voltage and amperage of your power source and the distance you need to run the wire. The size of the pump's discharge pipe depends on what type of pipe you plan to use (steel or PVC), the distance from pump to tank and the gpm flowrate that the pump will produce. The smaller the pipe is the higher the friction loss which makes your pump work harder to produce less water. We have several charts available to determine the best wire and pipe sizes to use for your pumping application so just give us a call and we'll design it for you.
Can I use solar or wind power to keep my stock tank from freezing?
That depends on how cold it gets at your site, if your tank is insulated/bermed and how you plan to keep your tank from freezing. Heating elements consume a lot of power to keep water from freezing which would require a large and expensive solar array to operate. There are bubbler system on the market that simply circulate the warmer water from the bottom to the top of the tank and those are much more efficient than a heating element. In very cold climates it is best to install a cover on your tank that leaves only a small portion of the water exposed and then berm your tank all the way around and on top of the cover. There are other more expensive and complicated methods of taping into the warm earth temperatures below the tank as well as insulating the tank and only providing water to the livestock when they come to the tank to drink so give us a call and we can direct you to companies that provide those products .
Will a solar pump stop pumping once the tank is full?
Yes if you design it that way. Most solar pumping systems utilize a controller that among other things will accept the input from a float switch in your tank which tells the pump when to start and stop. Some of the other functions of pump controllers are low water cut-off, lightning protection and load matching through the use of maximum power point tracking from the solar array.
Dear Friend, anybody can install dual solar Based pump system in village & earn Rs.91000/- as Its total expenditure is not more than Rs.1.60 lacs . Dear Friend, just we have installed 10 No. of dual solar pump system in villages. Its working is very much satisfactory. As the pump is running from 8.00 a.m. to 5.30 p.m. with a discharge rate of minimum 1000 liter per hour to 2500 liter per hour in this summer or on 5th June. As the women in rural area now did not get efforts for extracting water from bore well / well , also they can save efforts & time. So they are now tension free from water requirements. Also they are getting time for other activities. As the cost of all nodal agencies for this type of pump is Rs.2.51 lac anybody can earn up to Rs.91000/- from single installation.
Total expenditure of Rs.1.60 lac as fallows:
1. Groundfos Pump- SQFlex 2.5-2 - RS.90000/-
2. Solar panels 675 wp-- RS.40500/-
3. Seasonal Tracking System- Rs.9000/-
4. HDPE Pipe- 200 feet- Rs.5000/-
5. Misc.--- Rs.10000/-
6. Labour & Transportation --- Rs.10000/-

Addition To Dual Solar Pump Scheme.
by Vijaychakrawar on 24 MINUTES AGO in SOLAR ENERGY, CITY:MUMBAI
Now in all over India this scheme is executed through Village Panchyat with same solar panel capacity of 675 Wp , with this we can took required water within 3 to 4 hours. After this system is idle so in that period we could charge batteries and generate 3 to 4 KWHr ( Units) of electricity on which Panchayat office or school fans & school computers can run for the required period. So its more useful to society which is at grassroots. Also due to this the students from villages can compete to urban students.
So any body could suggest to GSDA or ZP of their district or heads of dept. or to the ministry of concern. So please take initiative & support nation .Its my appeal to every Indian who can understand this.
Or suggest me addresses to write to concern dept. so that I could do it.http://www.eai.in/club/users/vijaychakrawar/blogs/15507
HI,
I am very much intrested in knowing ore about solar energy and i want to use it for my agriculture and home in my village. we are having nearly 40 acrs of land and if you know any good manufactures can you pls let me know. how much it will be costing for each solar pump of 10 HP and how many hours it will run. details will be very helpfull for me to establish the same at my village.
thanks in advance
Hello Pmasineni
10hp is 7460 watts = 7.46KW
Solar panel of 1ft x 1ft can produce up to 14 watts.
Thus, to produce 7.46 kwatts you need 7460/14 = 532 sqft area of solar panels. With additional access space, you will need a total of about 1000 sqft or more area to install the panels.
1KW of solar panels would cost about Rs.2 lakhs.
7.46KW of solar panels will cost about Rs.15 lakhs.
The accessories like inverter etc may cost a couple of lakhs.
(or you use a DC motor directly powered by Solar panels). All in all, you are looking at some Rs.20 lakh budget.
Solar panel system works well for about 5 hours a day (10 am to 3 pm). It is advisable to construct a sizeable water tank to store the water that is pumped up and then distribute it when needed. Of course, it is also not a good idea to run a water pump for 5 hours nonstop in full drive. So, you need energy storage devices like heavy duty batteries.
If you ask me personally, I am not entirely in favour of a solar panel system for pumping water for agriculture, because you need water only for some days of the season. What will you do with the power on other days when harvesting time is around? If you can come out with plans to use the energy on other days, then I say, try Solar. You may also explore the good old cheaper way of a small wind mill that pumps water slowly all through the day, if you have some wind in that area. (And it is a classic and pleasing sight to watch a wind mill slowly pumping water!)
HELLO MADAM
I am working on solar and bio gas hybrid power plant and i have complete plan for execution as i found u are investor as well as researcher i need a chat session with u..or plz me appointment i need some help regarding my project
Dear Mr Barani,
First of all sorry for delay in replying and like to thank you for your valuable feedback and as per your above info , the cost is very high and i will sure look for other alternatives and your advise would be very much appreciated on Solar home lighting system like roof top off grid ( 1 KvA or 2 ) so that there will be a lighting for a minimum of 10 hours ( TV, f ridge and other appliances)
thanks in advance.
