California Homeowners Lost the 30% Credit.
ESAs Still Deliver It.

The residential ITC expired at the end of 2025. Solar Energy Service Agreements use the commercial tax credit, still active through 2027, to pass 30-39.2% in savings directly to you as a reduced system cost. No filing required.

The ESA Mechanism in California

How the Commercial Credit Reaches You

California homeowners cannot claim the residential ITC directly. But they can benefit from it through an ESA structure where a financing company holds temporary commercial title and passes the credit value back as a reduced price.

1

Company Holds Title at Installation

The ESA financing company, not you, holds commercial ownership of the system at the time of installation. This qualifies the system for the commercial, not residential, federal ITC.

2

Commercial ITC Is Claimed

The financing company files for the commercial ITC worth 30% base, or up to 39.2% in Energy Community zip codes. California has a significant number of EC-designated zip codes, particularly in rural and inland regions.

3

Savings Pass to You as a Discount

That credit value reduces your system cost before any payment structure is calculated. For Propel, it lowers the loan amount. For Participate, it reduces the upfront prepayment price. Either way, the savings flow directly to you.

4

You Pay a Fixed Fee and Own the System

Propel: fixed monthly payment for 25 years, automatic ownership at year 5. Participate: one upfront prepayment, no monthly fee, purchase option at year 6. Both deliver ownership without you claiming any tax credit yourself.

The California Split

Your Zip Code Changes the Math

California is split between Energy Community (EC) zip codes and standard zip codes. That distinction determines which ESA product prices better for your home.

Energy Community Zip Codes
39.2%

Propel Prices Better Here

The 10% ITC adder for Energy Community areas brings Propel's effective discount to 39.2% of system cost. That is applied before any loan is issued, reducing what you finance and your fixed monthly payment. Rural and former fossil fuel communities across California often qualify.

Non-Energy Community Zip Codes
30%

Participate Often Wins Here

In standard zip codes, the base 30% ITC applies. At that level, Participate Energy's Prepaid Lease, especially with a Tesla Powerwall, often delivers better value than Propel's structure. No credit check and no monthly payment also make it the right fit for homeowners who prefer a one-time payment.

The California ESA Rule of Thumb

In Energy Community zip codes where the ITC is 39.2%, Propel typically prices out better. In non-EC zip codes where the ITC is 30%, Participate Energy's Prepaid Lease, especially with a Tesla Powerwall, often delivers better value.

California Utility Rates

Higher Rates Make the ESA Discount Worth More

The higher your utility rate, the larger the gap between your current bill and a fixed ESA payment. California has three of the highest utility rates in the country.

SDG&E
$0.50
per kWh — San Diego County
Highest residential rate in CA. ESA economics are strongest here.
PG&E
$0.45
per kWh — Northern/Central CA
Broad territory with many EC zip codes. Strong Propel economics.
SCE
$0.40
per kWh — Southern CA
LA, Orange, Riverside, San Bernardino counties. Eligible for both products.
LADWP
$0.33
per kWh — City of Los Angeles
Not eligible for Propel or Participate programs.

California ESA Questions

Answers for CA Homeowners

The residential tax credit expired. Can I still get the savings through an ESA?
Yes. The residential ITC expired at the end of 2025. The commercial ITC is still active through 2027 for third-party owned systems. An ESA routes your system through a commercial owner, which claims the credit and passes the value to you as a discount. You do not claim anything on your tax return, but you receive the economic benefit as a reduced system price.
Does NEM 3.0 affect my ESA?
NEM 3.0 reduced export credits significantly, which makes self-consumption far more valuable than grid export. Systems sized under our programs are designed to maximize direct use of the power produced. Battery storage options from both Propel and Participate let you store surplus power instead of exporting it at reduced rates, which is the right strategy under NEM 3.0.
How do I know if I am in an Energy Community zip code?
The IRS updates Energy Community designations periodically. They cover census tracts associated with former coal mining, oil, gas, and related industries, as well as areas with significant fossil fuel employment. Our free assessment checks your specific zip code automatically. If you are in an EC area, Propel's 39.2% discount applies. If not, Participate is typically the better fit.
Is there a California state incentive on top of the federal ESA discount?
Some programs exist for income-qualified households through CPUC and utility rebates for battery storage. The primary driver of the upfront discount is the federal commercial ITC passed through the ESA structure. For a complete picture of CA state programs, see our California incentives page.
What if I want a Tesla Powerwall in California?
Participate Energy's Prepaid Lease includes Tesla Powerwall as a battery option. Propel Financing systems use Enphase IQ battery storage. If Powerwall is a priority, and your home is in a standard non-EC zip code, Participate is typically the better path for both the product structure and the battery option.
Can I qualify with an SDG&E bill in San Diego?
Yes. SDG&E customers are eligible for both Propel and Participate. With rates averaging $0.50 per kWh, San Diego homeowners typically see some of the strongest ESA economics in the state. A $300 monthly SDG&E bill translates to roughly 600 kWh of monthly usage, which a well-sized solar system can offset almost entirely.
