Zero Grid Export

Looking to only use...

traditional energy when you need it?

With our solar storage you’re able to tailor your usage to when you need it, without the extra costs of using the utility.

Zero Grid Export

So many of you live in an area with an abundance of solar while your electric power is very expensive and unreliable. Some utilities will not allow you to sell your excess production back, or will just pay you pennies for feeding your precious solar energy back to the grid.

The use of solar energy for self-consumption (or zero grid export) is your best option by reducing your electricity cost and providing sustainable living.

How does a zero grid export solar system work?

During the day the solar panels generate power for your home; and the excess power will be stored in a battery for later use. Your solar storage system will be your primary power source while still connected to the utility grid.
