Solar energy generation is a clean energy system that generates electricity from sunlight that falls on the earth. It can be used just about anywhere-in large buildings, in factories, and in residential homes
Solar energy is the conversion of sunlight into electricity. Sunlight can be converted directly into electricity using photovoltaics (PV). Photovoltaics were initially used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array.
Solar energy panels produce energy from daylight, not just direct sunlight, so they can still produce electricity on cloudy or overcast days. Solar energy can be used directly in your home to power lights and appliances – or exported to the electricity grid.
At night when your panels can’t produce electricity, you draw your electricity from the electricity network in the traditional way. A solar energy system contains two major elements: solar panels, which are usually mounted on a rooftop, and an inverter. The solar panels contain two layers of silicon, one with a positive charge and one with a negative charge. When the sun’s rays land on a panel, electrons move from one layer to another, creating an electrical current. The inverter takes the current and converts in into usable energy (240V AC).
Solar energy is great for the environment, very safe and emits zero carbon dioxide, fumes or pollution, and the panels will typically produce energy for at least 25-30 years.
