How Solar Power Works


1. Solar Modules (Panels)

Solar modules (panels) mounted on the roof or grounds of your property convert sunlight into DC power.

2. Inverter

This power is sent to a device called an Inverter (or power converter) which converts the DC Power from the Solar Modules to AC Power identical to that being sent to you from the Utility Grid. Below is an example of the type of inverters Solar Kauai recommends, a SMA Central Inverter.

3. Electrical Panel

Power travels from the inverter to your Electrical Service Panel. The power from the electrical panel will be distributed to any electrical loads in your home.

4. Utility Meter

When excess power is produced by the solar system, the power will flow into the Grid through your Utility Meter. This will cause your meter to run backwards gaining you a credit with the utility company.

5. Utility Grid

The utility grid automatically provides electricity when needed at night and during the day when your demand exceeds your solar production.

 6. Batteries (optional)

Batteries charge with energy produced by solar panels, making that energy available when needed, day or night. Batteries also enables your solar panels to produce energy during grid outages.
