Solar energy systems convert sunlight into electricity to power your home When you have solar panels on your home, you typically purchase less electricity from us because you are producing some or all the power your home needs City Light credits you for excess power your system generates and provides to the electrical grid If paired with battery storage, solar panels can also make your home
- Photovoltaics | Department of Energy
Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials
- Solar Photovoltaic Technology Basics | NREL
Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect
- Photovoltaics and electricity - U. S. Energy Information Administration . . .
A PV cell is made of semiconductor material When photons strike a PV cell, they will reflect off the cell, pass through the cell, or be absorbed by the semiconductor material Only the photons that are absorbed provide energy to generate electricity
