How Solar Works

Solar Panels
Solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) power.  Solar panels are positioned to maximize sun exposure.

Inverter
The DC power from the solar panels is sent to an inverter, where it is converted into alternating current (AC) power, or the standard electrical current used your home.  Energy Systems Hawaii uses micro-inverters which are on the cutting edge of solar technology.  Micro inverters are mounted on the roof.

Electrical Panel
AC power travels from the inverter to the electrical panel, often called a breaker box. This power is now ready to use in your home.

Utility Meter
The utility meter continually measures your electrical supply; when your solar system produces more power than you need, the meter literally spins backwards, accumulating credits with the utility company that will offset your next bill.

Your home remains connected to the utility grid to supply you with electricity when you need more power than your system has produced, such as at night.

Solar Production Monitoring
Monitoring allows you and Energy Systems Hawaii to continuously monitor energy production and make sure your system is running smoothly.

Energy Consumption Monitoring
Some micro-inverters continually monitor your home’s electricity usage. With a clear picture of your electricity patterns you can better manage your energy consumption and save money.
