Slide the second copper piece into place along the inner side of the bottle. Do the same with the heated piece of copper. The two pieces should not touch each other. Link an alligator-clip lead to every copper. Connect the lead from the second copper piece to the positive terminal of the micro-ammeter. The Solar Array The solar array is made of hundreds of photovoltaic solar cells that transform sunlight into electricity. To build an array, the PV cells have to be packed together to form modules that are positioned together to create an array. The bigger arrays can create more than 2 kilowatts or 2.6 hp of power. The heating process can be done by orienting the home well so that most of the windows face to the south. The windows should be sized properly too, so that optimal heat gain will be attained. The home has to be insulated to reduce loss of heat. Passive cooling is a kind of solar cooling. The main idea behind passive cooling is to reduce the impact of the sun by orienting the landscape and the house so that you get the most benefits out of cool breezes. It uses mechanical tools and equipment like fans, pumps and blowers to help people gather, store and distribute the heat all over the home. The systems can be air-based or liquid-based. Liquid-based systems involve the use of large water tanks or thermal mass for the storage of heat. Distribution is managed through radiant slab systems, hot-water baseboards and central forced air systems. The Components There are three main components in active solar energy. First is solar energy collection which involves the use of solar collectors. The most basic collector is the flat-plate collector. This is an insulated box covered with glass. Inside the box, you will see black absorber plates that absorb solar energy and transform it into heat. Aside from calculators, solar panels are now used to give power to homes, commercial buildings and other huge structures. Letting the Solar Panels Work Solar panels can gather clean renewable energy in sunlight form that will be converted into electricity. The average home has adequate roof area to let solar panels gather enough sun to be converted into DC current or AC current.
