NEM & Utility Approvals

Before activation, we conduct a final inspection to verify that everything meets local codes and utility regulations. For grid-connected systems, we also work with your utility provider to complete any necessary approvals and ensure compliance with programs like PG&E’s Net Energy Metering (NEM).

Frequently Asked Questions

What is an energy storage system?

Energy storage systems store electricity. When an energy storage system is paired with solar, any excess electricity that the system generates can be stored in the battery, which is part of the energy storage system. When the energy storage system is installed without solar, it will import electricity from the utility grid. Electricity stored in the battery can be used when solar or grid power is unavailable.

What kind of equipment gets installed?

Different energy storage systems have different components however all energy storage systems come with a battery. Other potential system components include inverter(s) (integrated or external) and backed up loads panel(s). Let us know what energy storage system you are interested in and we can send you a detailed list of the components included in that system.

How does the energy storage system work during an outage?

When there is an outage the energy storage system will start up and seamlessly provide electricity to the house loads. Energy storage systems either support whole house backup, all of the loads in the house, or a partial house backup, only certain loads.

How long will the battery last in an outage?

The duration of a battery’s charge will vary based on your electrical usage, house loads and the batteries state of charge when the outage occurs. Contact us for a more detailed analysis of your usage and the battery’s expected discharge rate.

What will my Energy Storage System back up?

Energy storage systems almost always support essential loads such as lights, refrigerators, and routers. Some systems are large enough to support the entire house which can include a washer or dryer and heat. We take into account your specific needs along with your house loads when we design our energy storage systems to ensure that you will get the most out of your system.

Can I connect my battery to a generator?

There are some energy storage systems that can be connected to a generator for additional support. Contact us directly to learn more about those systems.

Can I add a battery to my existing solar system?

Yes! Adding a battery system to your existing solar system is a great way to maximize your existing solar system’s production, boost your home’s resiliency against increasing grid instability, and increase the value of your home!

Can I install a battery if I don't have solar?

Yes! Adding a battery system to your home will allow you to have uninterrupted power during an outage, boosting your home’s resiliency against increasing grid instability and it will increase the value of your home!
