solar water heating systems
Has 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.
yes, and yes they do make them. I work for a solar company who owns a start up company that is producing this type of panel as we speak. there is more than one company doing this, expect popularity to rise within 2 years.
The problems they face are the panels getting too hot due to the mirrors for the pv side. the eff. is at around 18% for pv, 95% for the thermal part.
