How much energy, in kilowatt hours per year, would one square foot of solar cells produce?
I am wondering, how many kilowatt hours per year would one square foot of solar cells produce if there were 2732 hours of sunlight per year, equal to 7.5 hours per day?
Read MoreHas anyone heard of a solar system that combines photovoltaics and heating water?
I was thinking that if a system could both concentrate sunlight to get more voltage out of solar cells and in order to cool them, run water through the system. This way a building could get both electricity and heat with one system.
I meant to say increase power, not voltage.
Can anyone recommend solar cells and solar panels for a physics experiment?
I am doing a physics experiment where I need to compare the efficiency of the two. Solar panel for radiation>heat water and solar cells for radiation>electrical energy.
Can anyone recommend me some cells and panels which have lots of information about their performance, efficiency etc?
Many thanks!

I knew I’d heard something about researchers developing new solar cells which will triple the output efficiency of solar panels. When I go online to research this…NOTHING since the initial discovery at Berkely in 2002. Did some oil company gobble it up?

Currently, solar cells are about 30% efficient. How can nanotechnology may change this in the future? What do they expect solar cell efficiency to increase to and what impact would this have on the use of solar cells?
