It’s fairly old news that many cellphone towers in India are keen on solar PV for their power.
What is interesting are the numbers!
India currently has more than 250,000 cell phone towers, which consume about 2 billion litres of diesel per year. Each tower consumes an average 5 kilowatts of power and the consumption increases with the number of telecom operators using the tower.
The move from diesel to solar and other alternate sources of energy will result in a reduction of 5 million tons of CO2 emissions as well as a savings of $1.4 billion in operating expenses (opex) for telecom tower companies. These towers cost 30% of the operational expenses for the telecom company!
