Solar Rooftop Installations: Not Quite off the Ground

Energy from the sun can be harnessed primarily by two methods—solar thermal and photovoltaic or PV.  In the former, energy generation results from the conversion of solar energy into heat energy. The solar thermal method uses sunlight to heat up working fluids, such as hot water, hot air, and steam that can be set up for meeting numerous applications in different sectors, including power generation on a large scale, space heating, space cooling, solar water heating, solar cooking, and more (Solar Energy Corporation of India Limited, 2017). The PV energy conversion on the other hand  is the transformation of solar energy into electricity. This method directly converts the sun’s light into electricity using semiconductors such as silicon. The conversion of the energy into direct current (DC) is known as the photovoltaic effect. The energy thus generated can then be used in several ways. It can be used directly to run...
