7 Questions to Ask Before Signing Any Solar Contract

A solar contract is not a quick purchase. It is a 25 year commitment tied to your home, your finances, and in some cases your property title. Most homeowners sign without asking the questions that actually matter, and some only discover the consequences years later.

California has tightened consumer protections around solar sales recently, including new rules that took effect in 2026. Knowing what to ask before you sign protects you in ways a sales presentation never will. Here are seven questions worth asking every installer.

Question 1: Is the Installer Actually Licensed?

Why This Matters More Than It Sounds

California requires solar installers to hold a C-10 electrical contractor license or a C-46 solar contractor license. You can verify any license in about two minutes at cslb.ca.gov, and that single check eliminates a significant category of unqualified or fraudulent operators before you ever discuss pricing.

Ask for the license number directly and confirm it matches the company name on your contract, not just the name of the salesperson sitting in front of you.

Question 2: Does the Contract Include the Required Disclosure Document?

What California Law Now Requires

Every solar contract in California must lead with the CSLB’s Solar Energy System Disclosure Document as its actual cover page, not buried somewhere in the fine print. This document is meant to show total cost, financial obligations, and a standardized bill savings estimate in plain language before you commit to anything.

If a contract does not open with this page, or if the numbers on it do not match what your salesperson told you verbally, treat that as a serious warning sign. Verbal promises that contradict the written disclosure document rarely hold up if a dispute arises later, since the written document is what regulators and courts will reference first.

The disclosure document should also be written in the same language as your sales presentation. If your conversation happened in Spanish but the paperwork arrives only in English, that mismatch alone violates current disclosure requirements.

What Recent Legislation Changed

Senate Bill 784, signed into law for the 2025 to 2026 legislative session, strengthened consumer protections tied to residential solar agreements, home improvement loans, and door to door sales practices specifically. The law reflects a broader recognition that the solar industry generates a disproportionate share of consumer complaints compared to other home improvement categories.

That context matters when you are deciding whether to push back on unclear contract language. Regulators and courts now have more explicit grounds to side with homeowners than they did just a year or two ago.

Question 3: What Happens If I Need to Cancel?

Your Right to Cancel Is Real, But Time Limited

California gives homeowners a three day right to cancel most home improvement contracts, including solar agreements, without penalty. Use that window deliberately. Review every page of the contract during those three days rather than trusting your memory of the sales conversation.

If your contract was sold to you through high pressure tactics, asked you to sign quickly, or added pages after your signature, those circumstances may extend your options beyond the standard three-day window under existing California consumer protection law.

Question 4: Is This a Purchase, a Loan, or a Lease?

Why the Structure Changes Everything

A solar lease or power purchase agreement can look attractive on a monthly payment basis, but the long term math often tells a different story. Escalating payment clauses that are not clearly disclosed upfront can mean a 25 year lease costs tens of thousands more than a well structured purchase once you calculate the full term.

Ask directly whether escalator clauses exist, and if so, get the exact percentage and how often it applies in writing. A representative who cannot answer this clearly, or who rushes past the question, is giving you useful information by avoiding it.

Watch for Misleading Savings Promises

Some sales presentations still reference savings estimates based on outdated billing policy, or describe a 25 year lease as essentially free solar. Both framings have been specifically flagged as misleading by California regulators. A legitimate quote should explain your real savings under current net metering rules, not a policy that no longer applies.

Question 5: How Does Financing Affect My Property Title?

Understanding UCC-1 Filings

Many solar financing arrangements involve a UCC-1 filing, which secures the lender’s interest in the equipment itself, not your home. That distinction matters, because some lenders later see the filing during a title search and mistakenly treat it like a property lien, creating delays during a sale or refinance even though it should not legally block the transaction.

Ask whether your specific financing option requires a UCC-1 filing and what the process looks like to clear it when you eventually sell or refinance.

Question 6: What Does the Warranty Actually Cover?

Read Past the Headline Number

A warranty advertised as 25 years sounds reassuring, but the actual coverage varies enormously between companies. Some warranties cover only panel degradation, leaving workmanship and labor uncovered after just a few years. Others bundle in performance guarantees that pay you directly if the system underproduces.

Ask your installer to specify, in writing, exactly what the warranty covers and for how long each component is protected. A vague answer here is often a sign that the coverage is thinner than the marketing suggests.

It is also worth asking who actually backs the warranty. A warranty backed by a global panel manufacturer carries different weight than one backed solely by a small regional installer with no guarantee they will still be in business in ten years. If the installer themselves goes out of business, find out whether the manufacturer warranty still applies independently or whether it was tied to that specific company.

Question 7: Is the Total Cost Actually Transparent?

Look for Itemized Pricing, Not a Single Number

A trustworthy quote breaks down equipment cost, labor, permitting, and any financing fees separately, so you can see exactly where your money goes. Quotes that present only a single bundled number, or that include vague line items without explanation, make it difficult to know whether you are paying a fair price.

Programs structured around direct manufacturer relationships, like the Axia Solar program, tend to offer more transparent pricing simply because there are fewer layers between you and the actual cost of your system. That transparency is worth asking about directly, regardless of which company you are considering.

How to Verify Your Quote Before You Commit

Pull Your Utility History First

Before any sales conversation, pull twelve months of your own utility bills and know your actual annual usage. This lets you evaluate whether a proposed system size is realistic, or whether a salesperson is sizing a system around a generic estimate rather than your real consumption.

Get a Number to Compare Against

You can verify your solar quote details independently before sitting down with any installer, so you walk into the conversation already knowing roughly what a reasonable price range looks like for your home.

Frequently Asked Questions About Solar Contracts in California

What is the most important question to ask before signing a solar contract?

Verifying the installer’s CSLB license is the single most important step, since it is free, takes only a couple of minutes, and eliminates a significant share of fraudulent or unqualified operators before you discuss anything else.

Can I cancel a solar contract after signing?

California gives homeowners a three day right to cancel most home improvement contracts without penalty. Beyond that window, cancellation depends on the specific circumstances, including whether the contract followed required disclosure rules.

What changed with solar contracts in California in 2026?

Senate Bill 784 strengthened consumer protections around residential solar agreements, home improvement financing, and door to door sales practices, giving homeowners more explicit legal grounds in disputes over misleading contracts.

Should I be worried about a UCC-1 filing on my solar financing?

A UCC-1 filing secures the lender’s interest in your equipment, not your property. It should not legally block a home sale or refinance, though it is worth asking your installer how the filing gets cleared when the time comes.

Protecting Yourself Before You Sign

A solar contract you do not fully understand can cost you far more than a slightly higher monthly payment. The seven questions above cover licensing, disclosure requirements, cancellation rights, financing structure, property title impact, warranty coverage, and pricing transparency, the areas where homeowners most often run into trouble.
