There are some new solar panels that are pretty – a designer’s dream.
They’re glass and shaped like a pyramid. They stack out much like the leaves of roofing tiles. The sun is refracted to a small solar cell at it’s center providing beautiful clean energy.
The problem?
How do you keep them clean?
solar cells these days are not yet very efficient in generating electricity`’;
amorphous type solar cells are the cheapest option that we cant get if we want solar power~`*
even with the price drop, solar cells are still quite expensive if you want to get more than 500 Watts
Pyramidal solar do really help in generating alternative and renewable source of electric power.
