Photovoltaic residential projects do not allow energy storage

Is installing a larger PV system allowed?

• No. Installing a larger PV system in exchange for less energy efficiency measures is not allowed • A smaller PV system is allowed in exchange for adding additional energy efficient features, demand responsive measures, battery storage, or thermal storage systems Solar Ready Requirements Residential Mandatory § 110.10(a-e)

Does California need a photovoltaic system?

With many factors increasing the need for reduced energy usage, lower emissions, and less dependency on fossil fuels, California’s latest energy code has implemented stronger requirements for photovoltaic (PV) systems, with a large percentage of new buildings now requiring not only PV but also battery storage.

Can solar energy be stored in a battery bank?

Yes, in a residential photovoltaic (PV) system, solar energy can be stored for future use inside of an electric battery bank. Today, most solar energy is stored in lithium-ion, lead-acid, and flow batteries. Is solar energy storage expensive? It all depends on your specific needs.

Do new residential projects have solar?

• Most new residential projects will have solar, unless meeting an exception. Photovoltaic Residential Performance Method Photovoltaic Performance Method Residential ACM Reference Manual 2.1.5.5 Self-utilization credit for battery storage system with PV

When is PV not required?

PV is not required when the calculations show the required system is too small to really make a difference or because the roof area available for PV is very small when compared to the conditioned area of the building. The exceptions for battery storage are similar, although there are cases where PV will be required, but battery storage won’t.

Should I add a solar energy system to my roof?

You may be considering the option of adding a solar energy system to your home’s roof or finding another way to harness the sun’s energy. While there’s no one-size-fits-all solar solution, here are some resources that can help you figure out what’s best for you. Consider these questions before you go solar. See the Spanish version here.
