How to pay for solar in 2026 — in plain English.

The solar rules changed. We lay out the honest math for California homeowners so you can choose what works best for your budget and energy goals.

CRITICAL UPDATE: 2026 Federal Solar Tax Credit Rules

The rules changed this year. The 30% federal tax credit for homeowners who buy solar (with cash or a loan) expired on December 31, 2025. However, under Section 48E commercial credit rules, a third-party owned PPA (Power Purchase Agreement) still captures this 30% tax credit. The system owner claims the commercial credit and passes the benefit directly to you as a lower monthly rate. That's why, for most California homeowners in 2026, a PPA has become the smartest financial path.

Financial Security & Insolvency Protection

Many homeowners who bought solar in 2023 or 2024 were left stranded with broken systems when their installers went bankrupt during the solar market crash. If you finance your system with cash or a loan, you take on the structural risk of finding technicians if your sales company disappears.

With a PPA, however, this risk is completely eliminated. The system is legally owned and maintained by a multi-billion dollar manufacturing consortium (backed by Hanwha Qcells' $2.5 billion US assets). Because they own the equipment, they are financially and contractually responsible for its monitoring, repairs, and output performance. Your savings are institutionalized and safe.

Most Popular for 2026

PPA (Power Purchase Agreement)

$0 Down. Pay only for the clean power your system makes.

We design and install the solar panels at no upfront cost to you. You simply pay a set, lower rate for the clean electricity the system produces — typically below your current utility rate.

Best For:

Homeowners who want lower bills now with no upfront cost and nothing to maintain.

The 2026 Edge:

The only path that still captures the 30% federal credit — claimed by the system owner and passed directly to you as a lower rate.

Plain Example: Instead of paying the utility ~$280/month for power, you might pay ~$200/month for the same power from your own roof — with $0 down.

Solar Loan

Own your system with little or no money down.

Purchase the solar equipment using financing. You pay off the loan over time and own the system 100% once the loan term ends.

Best For:

Homeowners who want to own the equipment and don't mind a monthly loan payment.

The 2026 Reality:

Systems bought with a loan in 2026 no longer qualify for the federal tax credit. Ownership still builds long-term value through bill savings, but the upfront math is different than it was in 2025.

Loan Terms: Typically 10 to 20-year terms with fixed interest. Once paid, your electricity is virtually free except for grid connection charges.

Cash Purchase

Lowest lifetime cost, fastest payback.

Purchase the system outright. This completely eliminates financing fees and interest costs, giving you the fastest path to net savings.

Best For:

Homeowners with available capital who want the absolute maximum long-term financial return.

The 2026 Reality:

No federal tax credit on new cash purchases in 2026. However, you avoid all financing interest, meaning you own 100% of the utility savings immediately.

Financial Yield: Cash purchases typically produce the highest lifetime ROI, shielding you completely from utility rate increases.

Which financing option fits your home?

Answer 3 simple questions to see which path is likely your best financial fit.

Question 1: Do you want $0 upfront, or to own the system?

Question 2: Do you have cash capital you would put toward the solar install?

Question 3: What's most important to you?

PPA (Power Purchase Agreement) is likely your best fit!

Based on your answers, PPA fits because it requires $0 down, lowers your bills immediately, and passes the 30% federal credit benefits to you as a lower rate.

NEM 3.0 & Grid Independence

Why a battery matters in California now.

Under California's current utility rules (the Net Billing Tariff, often called **NEM 3.0**), the power your solar panels send back to the grid is worth far less than it used to be. The grid utilities pay only a fraction of the value for exported power during the day.

So, the smart move is to **store** your daytime solar energy in a home battery and use it at night, instead of selling it back cheaply. That's why we design most California systems with a **Tesla Powerwall 3** — you keep more of the clean power you make, protect your family from grid outages, and optimize your rate economics.
