Solar panels are a resource which produces renewable energy that uses photovoltaic (PV) systems to create electricity. A solar PV system uses sunlight to generate electricity, which you can then use to power up the electric devices in your home or office. Employing this renewable energy system at your location will drastically reduce your power consumption bills and will make only a good impact on the environment.
The sun always produces energy, counting back billions of years. The sunlight, that reaches the earth (solar radiation rays) can be easily converted into electricity. That’s what basically got the solar energy industry going…
But the idea of using this heat and converting it to usable electricity was hanging in the air for a long time already… Back In the 1830s, the British astronomer John Herschel used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food when he was on an expedition in Africa. Today, people use the sun’s energy for a variety of purposes.
Basically, solar energy can be converted into electricity by two different means:.
Photovoltaic (PV devices) or solar cells change sunlight directly into electricity. On a solar panel, single PV cells are usually clustered into groups and arrays that can be used in a variety of applications. They range from single small cells that charge calculators and watch batteries, to systems that power single homes, to large power plants covering many acres or high-rises.
