Not sure which path fits?
We break down the real numbers — including how monthly payments compare and where each option can go wrong — in our full lease, PPA, and loan comparison: Zero-Down Solar Financing in California (2026): Best Lease, PPA, and Loan Options.
If ownership is the goal, it also helps to know how long it actually takes a loan to pay for itself: Solar Payback Period California 2026: Step-by-Step Guide before you commit to a 20-year term.
The Dealer Fee Most Homeowners Never See
Solar lenders pay installers a 20–30% fee for every loan they close — and that fee usually gets folded into your loan principal. A system quoted at $22,000 cash can show up as $28,000 financed. Always ask for the cash price first. If it's more than 2–3% different from the financed price, ask why in writing.
This is just one line item. We cover the full breakdown of dealer fees: Zero-Down Solar Financing in California (2026): Best Lease, PPA, and Loan Options — and the other seven hidden costs most quotes don't mention: 7 Hidden Solar Installation Costs in California (2026): What Your Quote Isn't Telling You — in two dedicated guides worth reading before you sign anything.
California Solar Incentives in 2026
Federal Tax Credit (ITC):
The 30% credit for homeowners who buy a system with cash or a loan expired December 31, 2025 and does not apply to systems installed in 2026.
It's still available indirectly through leases and PPAs (third-party-owned systems) through 2027 — the company keeps the credit and typically passes some savings through in your rate. If you're wondering why solar is still selling well despite this, here's why demand hasn't slowed down: Why Is Solar Still Growing in California 2026 After the 30% Tax Credit Ended?
SGIP (Self-Generation Incentive Program):
California's main battery incentive in 2026. Standard rebate is around $250/kWh (~25% of system cost); low-income "Equity" and "Equity Resiliency" tiers can reach $850–$1,000/kWh, covering most or nearly all of a battery's cost.
Funds are limited and go on a first-come, first-served basis. The best way to maximize savings is stacking SGIP with NEM 3.0 the right way: SGIP Battery Rebate + NEM 3.0 in California: The 2026 Guide to Stacking Incentives and Cutting Your Payback Period.
NEM 3.0:
Export compensation dropped significantly — self-consumption (using power directly or storing it) now matters far more than sending it back to the grid. Here's exactly how the math changed: NEM 3.0 California Explained (2026): Solar Costs, Battery Savings & Is It Still Worth It, and if you want real numbers rather than projections, here's what actual bills look like two years in: 2 Years Into NEM 3.0: What California Solar Bills Actually Look Like in 2026.
PACE Financing:
Repaid through your property tax bill; flexible credit requirements, but read terms carefully (see the dealer fee warning above — PACE is a common area for high effective costs).
Where to Actually Apply
California State Loan Program
GoGreen Home Energy Financing — state-backed low-interest loans for solar + battery, offered through participating credit unions statewide (includes California Coast Credit Union, USC Credit Union, Frontwave Credit Union, and others). Rates commonly run roughly 3–8% APR depending on term length, well below typical installer-arranged loans.
Credit Unions (often the lowest no-fee rates)
Local/regional credit unions frequently post solar loan APRs 1–2 points below national lenders, with no origination fees or dealer markup — worth checking before signing an installer's in-house financing.
National Personal Loan / Bank Options (for comparison shopping)
-
LightStream, SoFi, Upgrade, LendingClub — unsecured personal loans usable for solar, no collateral required, funding often within days.
-
Home equity loan or HELOC through your bank/credit union — typically the lowest rates if you have equity, but requires appraisal and takes longer to close (2–6 weeks).
SGIP Battery Rebate
Apply Through Your Utility's Program Administrator
PG&E
SCE
SDG&E
SoCalGas
LADWP
Applications go through the statewide portal at selfgenca.com. Most homeowners apply through their installer, who handles the paperwork — but you can also apply directly.
Verify Any Contractor Before You Sign
-
CSLB (Contractors State License Board) — verify any installer's license at cslb.ca.gov before signing anything.
-
CPUC (California Public Utilities Commission) — oversees NEM and SGIP rules statewide; cpuc.ca.gov.
Once you've got financing lined up, the actual install process is fairly predictable. We walk through what to expect from contract to interconnection: Solar Installation Guide in California (2026): Costs and Process, including realistic timelines and inspection steps.
EV Charger Financing
Many of the same loan programs — including GoGreen and credit union solar loans — can bundle a Level 2 home charger into the same financing as your solar system.
There's also a federal 30C tax credit and state-level rebates that apply specifically to charger installation, separate from the expired solar ITC — see income limits and how to apply: Level 2 EV Charger Rebates in California 2026: How to Apply, Income Limits & 30C Tax Credit Rules.
If your panel needs an upgrade to support both solar and a charger, that cost can usually be rolled into the same loan — here's what a panel upgrade typically costs: Electrical Panel Upgrade for Solar & EV in California (2026).
And if you're weighing whether the combined investment makes financial sense, we ran the numbers on whether gas savings alone can cover solar, battery, and EV charging: Can Gas Savings Pay for Solar, Battery, and EV Charging in California?.

FAQ
Q: Does the 30% federal tax credit still apply in 2026?
A: Not if you're buying with cash or a loan — that credit expired December 31, 2025. Leases and PPAs can still pass through a version of the credit through 2027, which is one reason they've become more attractive for some homeowners this year.
Q: What credit score do I need?
A: Roughly 600+ for most leases/PPAs; 650+ is typical for loans, though credit unions and GoGreen-participating lenders sometimes work with lower scores than national solar-specific lenders.
Q: What would a typical monthly payment look like?
A: It depends heavily on system size, rate, and term — as a rough reference, a $1,000 loan balance through a program like GoGreen runs from about $9–$35/month depending on whether you choose a 10-year or 30-month term. Always ask your lender for the actual number on your system size before comparing offers.
Q: Can I add a battery to my financing?
A: Yes — and pairing with SGIP can make the battery portion far cheaper, especially if you qualify for the Equity or Equity Resiliency tiers.
Q: What happens if I sell my home?
A: Loans are usually paid off or resolved at closing. Leases/PPAs may transfer, but buyer approval is often required — check your contract before signing.
