Solar power systems collect energy derived from sunlight to make electricity. Solar Cells In their essence are solar panels, assembled by photovoltaic cells that catch the rays and turn it into electricity. These panels come in different sizes and can be installed on rooftops or in ground-mounted solar farms. The primary functions of a solar power system include capturing sunlight, converting it into electricity which can be used right there on site or fed back to the grid, and sometimes putting this in batteries for use during periods when there's no direct sun. Technological features Here are some examples of high-quality solar cells: High-efficiency solar cells are being developed, which cut down the cost of electricity. Anti-reflective coatings are being researched and put into mass production. Durable materials that last a long time in any weather and can stand up to high winds. The range of applications is vast: from small-scale household photovoltaic systems to centralised power supply at the town or village level, or even huge solar power plants which alone can account for huge amounts on their own. Indeed solar power has become an important way to help reduce emissions from greenhouse gases and lower our carbon footprint.
