What is the best price of Suntech Solar Panels in Pakistan and tell me is it reliable for small firm
ReplyDeleteThe development of solar energy goes back more than 100 years. In the early days, solar energy was used primarily for the production of steam which could then be used to drive machinery. But it wasn't until the discovery of the "photovoltaic effect" by Edmond Becquerel that would allow the conversion of sunlight solar electric energy. Solar panels found their first mainstream use in space satellites. For most people, the first solar panel in their life was probably embedded in their new calculator - circa the 1970s!
