Big Solar


Solar power tends to be big because it covers  a large amount of area with its panels.  The world’s largest solar thermal power plant  is nearly double the size of the original largest in Denmark — is now online in Saudi Arabia, reinforcing the notion that this  Saudi Arabia has a lot of oil and a lot of sunlight.   As long as the sun shines this sort of power is virtually limitless.    Plentiful sun shines down on Saudi Arabia, and the panels that allow this project to run are massive. Each one covers 107 square feet  and weighs 375 pounds . The panels have a transparent coating to enhance their performance, and they also require a special mounting system to keep them bolted to the roofs when Saudi Arabia’s notoriously vicious sandstorms hit Riyadh.  These panels have a 95% absorption rate and weigh 170kg. They are 10 square meters wide by 5 square meters long and are especially designed to withstand the desert’s fierce sandstorms.
