How Solar Panels Work
Every day the sun delivers an enormous amount of free energy to the Earth. Solar panels capture that sunlight using photovoltaic (PV) cells and convert it into direct current (DC) electricity.
However, your home cannot use DC electricity directly. That’s where the rest of the solar energy system comes into play.
A modern solar installation follows a simple process:
- Sunlight reaches the solar panels.
- The panels generate DC electricity.
- A solar inverter converts DC electricity into alternating current (AC).
- The electricity powers your household appliances.
- Any unused electricity charges a home battery.
- Surplus electricity may be exported to the electricity grid where permitted.
- Solar panels convert sunlight into usable electricity for your home through a simple but highly efficient process.
Instead of relying entirely on electricity supplied by your utility company, your property becomes its own renewable power station capable of generating clean electricity throughout daylight hours.
