Solar PV cells are made up of layers of materials that are semi conductive just silicon. The moment light strikes the PV panels, the cells creates electric fields in all layers. The stronger the sun rays are the more electricity is generated. During cloudy days, lesser amount of electricity is produced. The following are advantages you get from Solar PV:
- Homeowners can reduce electric bills. Sunlight is always available and it is free. Once the initial installation is paid for, you can enjoy reduced electricity costs.
- Homeowners can get paid by generating more electricity than they used. In the U.S. and certain countries in Europe, government supports the Feed-In Tariff s. This is when users of renewable energy sources are paid whenever they generate electricity from sources like the wind power or solar panels.
- Renewable energy sources help save the environment. Electricity from sunlight supports green movement. It does not emit carbon dioxide and other harmful pollutants.
