Photovoltaic solar panels directly convert light energy (photons) into electricity. Currently, the efficiency of these panels is still considered very low. The average round in the top 18% and 24% reach. This means that in an ideal situation, only this percentage of light that actually hits the panel is converted into electricity.
Photovoltaic solar panels can be seen in several respects similar to computer chips, mainly because it also made using silicon semiconductor materials. While progress is being made with numerous technologies and much of Silicon Valley innovators are focused on studying how to improve and reduce manufacturing cost, they remain unaffordable for mass consumption now. An installation for a standard American house is around $ 50,000.
