Solar panels are installed on a roof of a building (or anywhere where there is direct sunlight and less shading) to capture the sun’s light energy and converts to (DC/ direct current) electricity. This electrical energy is transferred directly to batteries that act as a storage container for the harvested energy. This energy is converted to regular household electricity called (AC / alternating current), using a device called a power inverter, and now can be used to power electrical appliances in that building. Every solar system has to be “sized” (designed) for the electrical load (demand) that will be placed on it. If a building’s electrical consumption (load) is large, then a large solar system will be required to supply the consumption (load) demand. A larger system requires more equipment and therefore cost more. It is very important to get a professional solar assessment to determine your solar needs for your building.
