A Question About Solar Energy?
I'm doing a project on solar energy. The only thing I have not found was the efficiency of solar energy compared to other kinds of existing or future/possible kinds of energy. Does anyone know of any sites or any facts that would help me? It'd be greatly appreciated. Thank you so much in advance.
The kinds of solar cells you and I can buy "off the shelf", right now, are in the 18%- 22% efficiency range.
The kind of solar cells that fly on the international space station (ISS) -- which are the most efficient production cells in the world -- are still only 27.5% efficient. With concentrators (little Fesnel lenses), they can possibly reach about 35%. These efficient cells are *very* expensive and not practical for public use.
Here's a link to the ISS solar cell manufacturer.
