Everything You Need To Know About The 2022 Title 24 California Solar Mandate Changes

August 8, 2022

Title 24 California

The CEC released the 2022 Title 24 California solar mandate changes including new requirements for solar PV, battery storage, and EV charging to encourage the installation of onsite clean energy for new buildings. Below is a summary of the new California code requirements for both the Title 24 mandate and CalGreen, as well as recommendations on how to approach these new requirements.

Effective January 1, 2023, these code updates extend requirements for the installation of solar PV and battery storage in California for the following building types in the table below. The changes also include a requirement for new multifamily low-rise buildings to be battery ready, meaning they must install electrical infrastructure to support a future battery system. The solar and battery standards for select building types are designed to maximize the use of onsite solar and avoid high electricity demand to be less reliant on gas-powered plants.

With these code updates, it is crucial to engage early with a solar, battery storage, and EV design team in order to avoid mistakes and costly band-aid solutions later on. From setting aside space for solar PV and batteries on-site to making sure your switchgear can support the system, bringing on a team of experts is essential to a successful renewable energy compliance project.

Financing options like Solar Roof Lease payments also give developers the opportunity to generate revenue with no Capex. It is all in the numbers – going beyond code by installing more solar PV is proven to increase property value and NOI for every property.
