How Solar Energy Works
A - Solar Panels
Solar Panels: Solar panels, sometimes called solar modules, are typically installed on the roof of a home or commercial building. These solar panels are made up of photovoltaic (PV) cells. These cells convert sunlight into direct current (DC) power.
B - Micro Inverters
The DC power from the solar panels is sent to an inverter. This inverter converts the DC power to alternating current (AC) power, which is the standard electrical current used in your home.
C - Battery backup
The excess power your solar panels have generated feeds into your battery backup for storage and can be used when you need it.
D - Electrical Meter
AC power travels from the inverter to the main electrical service panel, often called a breaker box. This power is now ready to use in your home.
E - Utility meter
The utility meter continually measures your electrical supply. When your solar power system produces more power than you need, the meter literally spins backward, accumulating credits with the utility company that will offset your next bill.
F - Utility Grid
Your home remains connected to the utility grid and supplies you with electricity when you use more power than your solar power system produced. This typically happens at night.
