Parking lots are one nice location to have solar panels.
Why?
You have vacant space that is not used for anything, your cars and other vehicles get better shade (if there was none earlier) and well, you generate some electricity as a bonus!
Thus, solar panels on industrial and commercial parking lots have seen significant adoption in the last couple of years.
Here is a nice blog post from Solar Mango providing details on this interesting topic of solar panels on parking lots. (part of Innovations in Solar series)

An ordinary sun based board is something like 3 feet wide and 4.5 feet long, and gives something around 200 watts of force. A run of the mill device or air compressor may have a 1 hp engine, which is something like 800 watts. So you’d require 4 sun powered boards for each device you keep running at once, at high twelve. Whatever other time, or at an overcast time, you will create less power, so we should figure 6 boards for every instrument in addition to a few batteries on the off chance that there are mists.http://www.worldsolarpanels.com/
Most commercial solar photovoltaic cells are made from silicon. To push the efficiency higher, one of the best options is to make tandem solar cells – that is, cells that use multiple light-absorbing materials. For perspective, silicon solar cells have a record efficiency of 25.6%. Using one light-absorbing material, the theoretical limit is 34% efficiency. Using two light-absorbing materials in tandem pushes the theoretical limit to 46% efficiency.
Tandem solar cells from two light-absorbing materials: silicon and the metal-halide perovskite, a new material with the potential to be manufactured at low cost.
Silicon-perovskite tandem solar cells and may provide a path forward for the solar industry to make high-efficiency, low-cost solar cells.
