How Does Solar Power Work?

Understanding Solar Power
As shown in the animation above, rugged, weatherproof solar photovoltaic panels are installed on roofs, pole mounts, or ground mounts and angled to capture the maximum amount of sunlight. These modules have no moving parts and require little to no maintenance.

Sunlight enters the silicon-based panels, where photons from the sun collide with electrons in the panel, generating direct current (DC) electricity.

The DC power enters the inverter box, which is connected to the circuit breaker. The inverter converts the DC power into alternating current (AC) power, which is then used—just like electricity from the power company.

At “peak” sunlight hours, many solar electric systems produce more electricity than a home or building needs, essentially making the electricity meter spin backwards. If the system is connected to the grid—and most are—the system owner can sell the extra electricity back to the power company through a net metering agreement. Opting into a net metering program is very simple, and the entire process is seamless. Once the system owner has opted in, payments or credits begin.
