A photovoltaic (PV) system converts sunlight into electricity using solar cells. Typical components include solar panels, an inverter, batteries (optional), and a charge controller. PV systems can be grid-connected or standalone and reduce emissions by replacing fossil-fuel electricity.

What does a photovoltaic system do?
It turns sunlight into electricity that powers homes or businesses.

Sunlight to DC power, inverter to usable AC electricity.
Homeowners install PV panels to lower bills and sell excess power back to the grid, while businesses use larger arrays to power facilities.
Keep panels clean and inspect wiring regularly to maintain peak PV performance.
“Keep panels clean and inspect wiring regularly to maintain peak PV performance.”
PV technology dates back to the 19th century and became widely used after space-race innovations.
Do PV systems work on cloudy days?
Yes, but they produce less power when sunlight is reduced.
Is a battery required?
No. Grid-tied systems can run without batteries, but batteries add backup power.
How long do PV panels last?
Many panels last 25 years or more with gradual efficiency decline.
