Solar cells mounted on panels absorb sunlight and turn it into energy.

It is a bit like photosynthesis in plants. Photovoltaic panels (PVP) as they are called, used to be really expensive but have dropped almost 50% in price over the last 4 years.

They are now much cheaper and will further fall in price allowing all but the poorest folk to access them. This paper explains how they work.


Paper will be available soon.
