Implementation of SolarAPP+

March 2, 2023

The California State Association of Counties, along with the League of California Cities held a webinar on February 2nd on the requirements of Solar Access Act (SB 379, Wiener).

Last year, California lawmakers passed the Solar Access Act (SB 379, Wiener). This new law requires most counties and cities to adopt SolarAPP+, an automated online permitting platform for standard residential solar and storage systems. 

Compliance deadlines depend on the size of the community, and some are exempt entirely. Counties and cities with more than 50,000 residents must adopt SolarAPP+ by Sept. 30, 2023. Counties and cities with 50,000 residents or fewer must adopt SolarAPP+ by Sept. 30, 2024.

Counties with fewer than 150,000 residents, cities with fewer than 5,000 residents, and all cities in those counties are exempt.

SolarAPP+ automates and standardizes building departments’ permitting processes for simple residential rooftop solar systems. The platform asks the contractor a series of questions to verify the solar system’s design is up to code, runs automated code compliance and plan check, and then — for compliant systems — automatically issues a permit so that installation can begin.

The platform was developed by the National Renewable Energy Laboratory in collaboration with building safety and industry stakeholders. It is free for all permitting offices.

Noncompetitive funding available until May 1, 2023

The California Energy Commission is providing $20 million in grants through its CalAPP program to help cities and counties recover the cost of establishing an eligible automated, online solar permitting platform.

According to the Commission, “most of the funding will be used to reimburse staff or consultant time associated with implementing the software.” However, there are other secondary permitted uses, such as hardware, installation, and maintenance costs. Several helpful resources are available, including:

The National Renewable Energy Laboratory has additional resources on its SolarApp+ website. It is also holding live platform demonstrations on Tuesdays and Thursdays, now through June 29.

The SolarAPP+ onboarding process can be started online. For questions, email team@solar-app.org.

For information on the CalAPP grant program, please review the program page. The grant application form is easy to fill out and grants are noncompetitive. Funding will be awarded on a first come first serve basis. Applications are due May 1, 2023.
