Upcoming Program Participation Deadlines

  • The deadline to approve new NSHP Program reservations is June 1, 2018. The deadline to submit new reservations with a guarantee of review before the approval deadline was April 1, 2018. A high volume of applications were received by the deadline. As provided for in the NSHP Guidebook, applications may be submitted after April 1, 2018, but these applications are not guaranteed review prior to the June 1, 2018, deadline and therefore may not receive approval for participation in NSHP. All funding amounts in approved reservations are final as of June 1, 2018.

  • The payment claim form submittal deadline is August 31, 2021, in order to satisfy the December 31, 2021, statutory payment disbursal deadline, required by SB 83 (2015).

The California Energy Commission's New Solar Homes Partnership (NSHP) is part of the comprehensive statewide solar program, known as the California Solar Initiative. The NSHP provides financial incentives and other support to home builders, encouraging the construction of new, energy efficient solar homes that save homeowners money on their electric bills and protect the environment.

Applicants are encouraged to submit reservation applications and payment claims using the online application tool, when possible.

New reservation applications and payment claims submitted by mail must be sent to the Energy Commission at the address identified on the GoSolar California contacts page. All inquiries must be directed to the Energy Commission at 1-844-454-2906.

California Public Utilities Commission Decision 16-06-006 requires the state's Investor Owned Utilities (IOUs) to provide $111.78 million in funding from ratepayers for continuation of the Energy Commission administered NSHP program. The additional funding can be utilized only after program funds available through the Renewable Resources Trust Fund (RRTF) have been exhausted.

At the point in time when RRTF funds have been exhausted, all new reservation applications will be associated with the additional funding transferred from the IOUs to the Energy Commission to determine the maximum overall program funding expenditure. Individual reservations are not guaranteed for payment under a particular funding source. Payment claims will be paid with RRTF funds until these funds are exhausted. Payments made with the additional IOU funds are subject to Energy Commission approval of an applicant's claim for final payment of incentives and transfer of program funding from the IOUs to the Energy Commission for payment to the applicant. Payment claims fulfilled with the additional IOU funds may be subject to additional delays to provide for the transfer of program funding following claim approval.

Continued Funding of NSHP Program

CPUC Decision 16-06-006 - Decision Funding Authorizations and Related Measures for Continuation of the New Solar Homes Partnership Program, Approved June 9, 2016

On November 13, 2015, the Energy Commission requested funds from the California Public Utilities Commission (CPUC) to meet the statutorily authorized $400 million for incentives under SB 1 for the New Solar Homes Partnership (NSHP) Program. The Energy Commission also requested to continue administering the program.

At its June 9, 2016 Board Meeting, the CPUC voted and approved Decision 16-06-006, Decision Funding Authorizations and Related Measures for Continuation of the New Solar Homes Partnership Program.

This CPUC Decision provides the NSHP program with additional funding in the amount of $111.78 million to provide for continuing financial incentives for homeowners, builders, and developers to install solar energy systems on new, energy efficient residential dwelling under provisions of the program. The CPUC Decision also designates the Energy Commission to continue as the administrator of the program.

What is an NSHP Solar Home?

In California's New Solar Homes Partnership, a solar home is a highly energy efficient home that uses photovoltaic (or PV) modules to generate electricity from the sun. While the science to convert sunlight directly into electricity has been around for decades, in recent years both the technology and economics have improved for photovoltaics, and now systems are becoming mainstream. Currently, California has tens of thousands of homeowners enjoying the benefits of solar on their homes.

A solar home with high energy-efficiency features offers homeowners:

Save Money - Go Solar!

Using California's abundant sunshine, homeowners save money on their bills through new energy efficient solar homes.

Coupling energy efficiency with solar technology reduces the homeowner's total energy needs and reduces utility bills.

Get paid for energy efficiency.
Homes from builders participating in the New Solar Homes Partnership are at least 15 percent more efficient than current building standards.

Builders are also encouraged to achieve 30 percent greater efficiency. California's utilities may offer additional incentives to help meet these efficiency levels.

Protect against rising energy costs.
Energy efficiency and solar energy give homeowners more energy independence because they are better protected against rising energy costs.

Solar homes generate power when electricity is the most expensive.

Earn tax credits.
Solar homes also qualify for a federal income tax credit. Energy efficiency measures may qualify the home for an additional $2,000 in federal tax credits.

Save the Environment - Go Solar!

Best of all, buying an efficient solar home is one of the most significant personal actions one can take to cut air pollution and greenhouse gas emissions, while helping to conserve precious energy resources for future generations. Plus, it reduces the need for costly new power plants.

Solar homeowners can be assured that their solar system works because they are backed with a 10-year system warranty. PV modules are warranted to last 20 years or more. Plus, the solar system must be tested and perform up to specifications before anyone can collect the incentive money from the NSHP.
