What are Photovoltaic (PV) Devices?

How is Solar Energy Used? 

Solar Photovoltaic (PV) devices are usually solid in state and are made of semiconductor material, usually comprised of silicon which conducts electricity more than an insulator, but less than pure conductors like copper or aluminum. Also, photovoltaic devices can be constructed as stand-alone systems to give power output ranging from microwatts to megawatts. So, How is solar energy used? Solar PV devices can be used as the power sources for:

1. Calculators

2. Watches

3. Water Pumps

4. Remote Buildings

5. Communications

6. Satellites & Space Vehicles

7. Homes, Businesses or Government buildings

8. Megawatt-scale power plants

Switching to solar PV is the process of going solar through the adoption and use of photovoltaic (PV) devices, including solar panels to provide electrical as well as heating energy to homes and businesses. 

The process of Switching to Solar PV for homeowners and businesses is today simplified by online solar tools like the EnergySage that have developed solar energy market places where consumers can compare and contrast different solar energy plans at the best prices possible.
