The Energy Commission has extended the reservation deadline to March 31, 2021, for projects with original expiration dates from October 1, 2019, through December 31, 2020. Please see the “Limited Program Time Extension” section below for details.
The NSHP program was created as part of a statewide solar incentive program called the California Solar Initiative (CSI). Launched in January 2007, the NSHP program is the California Energy Commission’s (CEC) component of the CSI to provide incentives for the integration of solar energy systems in new home construction in investor-owned utility (IOU) territories. The NSHP Program is no longer accepting new reservations for solar incentives but continue to complete payment of claims submitted. Please see the “Program Deadlines” section below for details.

- By CEC resolution adopted in December 2020, the reservation expiration dates for all NSHP reservations that expired or will expire from October 1, 2019, through December 31, 2020, have been extended to March 31, 2021. To receive payment, a complete NSHP payment claim package for such projects must be received no later than March 31, 2021, and must still adhere to all other requirements in the NSHP Guidebook. With this change, and in light of the deadlines established to meet the deadline for NSHP payments to be made by December 31, 2021, the limited extension of reservations previously provided in the NSHP Guidebook, are no longer needed. All projects now have an expiration date consistent with the last day by which payment claims must be submitted.
- If you intend to submit a payment claim application for an expired project impacted by this resolution, please email the Renewable Call Center at email@example.com with your Project and Site ID, and indicate you wish to unlock the site. Our staff will review your site for eligibility and respond to your request when it is updated in the program web portal at www.newsolarhomes.org. If you have any additional questions or concerns, feel free to contact the Renewable Call Center using the contact information displayed at the top of this webpage.
- The New Solar Homes Partnership (NSHP) program is no longer accepting applications for new reservations.
