A solar hot water system requires a hot water storage tank that keeps the water at a high temperature. In a two-tank system, water is heated with solar collectors and then stored in the first tank. A one-tank system has a single cylinder with twin coils.
A solar inverter that produces pure sine wave is suited for homes that require an optimum performance for appliances such as TVs, computers and stereos. A modified sine wave solar inverter is cheaper and can run most appliances.
Solar cell efficiency tells us the amount of solar insolation that is converted into electricity. It usually lies between 12.5 and 15%. In laboratories, scientists are working on solar cell efficiency constantly.
Many commercial solar panels can be very expensive, but people may opt to make their own solar panels at home. Learning how to make a solar panel can also teach people some basic concepts that will allow them to better understand how solar panels work.
