California solar decisions
How much does it cost to lease solar panels in California?
This page gives no payment figure, because any figure here would be invented and would not describe your roof, your usage or your tariff. What it does give you is the mechanism: what a lease or PPA payment is built from, which contract terms move it, and the document California requires the provider to hand you with the total on it.
Updated September 18, 2026 · California Rate Relief is a private solar referral service.
Why there is no single number, and who is required to give you one
A solar lease payment is not a list price. It is the output of a calculation about one roof, one production estimate, one contract term and one household’s electricity use. Two quotes for the same address can be built from different assumptions and still both be described as a monthly lease payment.
California does not leave that to a sales conversation. Business and Professions Code section 7169(a) requires a disclosure that gives the consumer “accurate, clear, and concise information regarding the installation of a solar energy system, total costs of installation, anticipated savings, the assumptions and inputs used to estimate the savings, and the implications of various financing options” (verified 17 September 2026). Section 7169(b) then requires the Solar Energy System Disclosure Document on the front page or cover page of every solar energy contract, in boldface 16-point type, carrying “the total cost and payments for the system, including financing costs,” information on how and to whom complaints may be made, and the consumer’s cancellation right under section 7159. The CSLB publishes the document itself, in three-day and five-day versions in English and Spanish, along with the separate Solar Energy System Supporting Information form (verified 18 September 2026).
So the answer to “how much” exists, in writing, in a specified place, produced by the company that would actually install the system. Everything below is about reading it.
What a lease or PPA payment is actually built from
These are the inputs. None of them has a standard value, which is why a figure quoted without them tells you nothing.
- System size and design. The DC system size, the module and inverter models, and the roof layout the proposal assumes.
- The production estimate and its assumptions. How much the system is projected to produce, and what shading, tilt, orientation and loss assumptions produced that projection.
- What the payment is charged against. A lease generally charges for use of the equipment. A power purchase agreement generally charges for the output. That difference changes what happens in a low-production year.
- Contract term. How many years the obligation runs.
- Payment timing. Monthly, or prepaid in whole or in part. A prepaid label does not by itself end future payments.
- Whether an escalator applies. A clause that changes the payment over the term.
- What else is in scope. Storage, roof work, electrical panel work, trenching, permits and interconnection handling.
- What utility charges remain. Imports, fixed and delivery charges, and whatever the proposal assumes about export compensation on your tariff.
Before relying on any statement about export compensation or the size of the remaining bill, ask the provider for the tariff and the assumptions in writing and check them against your own utility account. This page does not describe current export terms.
Escalators: two different things get called the same name
Both come up in a lease conversation and they are not the same number.
- A contract escalator changes what you pay the provider over the term. It is a clause in your agreement. The only way to know what it does is to read it and to ask for the full payment schedule, year by year, for the whole term. Do not accept a single monthly figure as the answer.
- A utility rate escalation assumption is an input to the provider’s savings estimate, not a charge. It is the rate at which the estimate assumes your utility prices will rise. The CPUC states that “solar providers are allowed to use a maximum electricity rate escalation of 10% in any calculation, as of 2025” (verified 18 September 2026). Two otherwise identical proposals can show very different savings on this assumption alone, which is why section 7169(a) requires the assumptions and inputs to be disclosed alongside the estimate.
Ask which of the two a salesperson is describing, every time. More on the first of them in what an escalator clause does.
The bill does not go to zero
The CPUC lists “You will never pay an electricity bill ever again after a solar system is installed” among the claims a consumer should treat as false, and states that customers who take out a solar loan or sign a lease or power purchase agreement “will also receive a monthly bill from a loan company or solar provider” (verified 18 September 2026).
That means the comparison is the lease payment plus whatever utility bill remains, against the utility bill you pay now, on the same usage history and the same tariff. A proposal that compares only the lease payment against your current bill is comparing two different things.
Put the quotes on the same basis
A smaller monthly payment can hide a longer contract, less equipment or a larger remaining electric bill. Ask each bidder to fill the same gaps.
| Compare | Get it in writing |
|---|---|
| System and output | Same DC system size, module/inverter models and roof layout; monthly production with shading and losses shown. |
| Battery and backup | Usable kWh, continuous output, backed-up circuits, reserve setting and expected replacement costs. |
| Price and scope | Separate solar, battery, roof, panel upgrade, permits and interconnection. Compare cash prices before financing. |
| Utility bill | Same usage history and tariff; separate onsite use, grid imports, export credits and remaining fixed/delivery charges. |
| Contract and service | Who installs and who services it; written coverage by address, insurance, license record, exclusions and warranty claim process. |
| Payment and transfer | Cash, loan, lease or PPA; upfront costs, APR or escalator, total payments, home-sale and end-of-term terms. |
The terms that decide a cost you have not been quoted
Most of what a lease or PPA will cost over its life is not the monthly number. Ask where each of these appears in the contract, by section.
| Term | What to ask for in writing |
|---|---|
| Term length and end of term | How many years, and what the stated options are at the end: renewal, removal, purchase, or nothing specified. |
| Buyout and early termination | The formula in the contract, not a verbal estimate, and whether any fee applies for ending early. |
| Assignment at a home sale | Whether a buyer may assume the agreement, what qualification applies, and what happens if no assignment occurs. Section 7169(c)(11) identifies the impacts of the financing or lease terms on the sale of the home, “including any balloon payments or solar energy system relocation that may be required if the contract is not assigned to the new owner of the home,” as disclosure content — so ask for the clause by name. |
| Repair, monitoring and insurance | Who is responsible for each, for how long, and what is excluded. |
| Production guarantee | Whether one exists at all; what output level it guarantees; how a shortfall is measured; what the remedy is and who initiates it. A production estimate is not a guarantee. |
| Roof and equipment access | What happens, and who pays, if the roof needs work or the system needs removal and reinstallation during the term. |
Check the provider before you compare the payment
The CPUC directs consumers to get the contractor’s CSLB licence number, and the individual home improvement salesperson registration number if they were contacted by phone or door-to-door, and states that the licence must be active and in classification C-46 (Solar Contractor), C-10 (Electrical Contractor) or B (General Building Contractor) to be valid for this work (verified 18 September 2026). The CSLB lookup lets you check both.
The CPUC also requires solar providers to give you its consumer protection guide, and it publishes the guide itself. Read the copy you are given rather than a summary of it.
Before you sign
Civil Code section 1689.6(a) gives a buyer at least three business days to cancel a home solicitation contract, and five business days if the buyer is a senior citizen — defined in section 1689.5(f) as a person 65 years of age or older. For a home improvement contract, section 1689.6(a)(2) runs that period from the buyer’s receipt of a signed and dated copy of the contract (verified 17 September 2026). The CPUC states the same three-day and five-day windows.
Ask for the completed Solar Energy System Disclosure Document and the Supporting Information form, in the language the sale was negotiated in, and keep every signed version and change order.
Questions and answers
What does a solar lease cost in California?
There is no single figure, and any number a web page gives you is invented. Business and Professions Code section 7169(b) requires the Solar Energy System Disclosure Document on the front page or cover page of every solar energy contract, in boldface 16-point type, carrying “the total cost and payments for the system, including financing costs.” The number comes from the provider on that document, for your roof, your usage history and your tariff.
Will my solar lease payment go up over the term?
It can, if the contract contains an escalator. That is a contract term, not a property of the word “lease,” so ask for the escalator clause and the full payment schedule for every year of the term in writing. Keep it separate from the utility rate escalation assumption used inside a provider’s savings estimate; the CPUC states that “solar providers are allowed to use a maximum electricity rate escalation of 10% in any calculation, as of 2025.”
Is a solar lease the same thing as a PPA?
No. A lease is a payment for use of the equipment. A power purchase agreement is a payment for the electricity the equipment produces. Everything else — term, escalator, maintenance, transfer at a home sale — is a contract term rather than something the label settles.
Will I still get an electricity bill if I lease solar panels?
Typically yes. The CPUC lists “You will never pay an electricity bill ever again after a solar system is installed” among the claims to treat as false, and states that customers who take out a solar loan or sign a lease or power purchase agreement “will also receive a monthly bill from a loan company or solar provider.” Compare the lease payment plus the remaining utility bill, not the lease payment alone.
What should I compare between two solar lease quotes?
Put them on one basis first: the same system size and design, the same production assumptions, the same usage history and the same tariff. Then compare the total of payments over the full term, the escalator clause, the term length, the end-of-term options, the buyout and the home-sale assignment terms. A smaller monthly payment can sit on a longer contract, less equipment or a larger remaining electric bill.
What if I change my mind after signing?
For a home solicitation contract, Civil Code section 1689.6(a) gives at least three business days to cancel, and five business days if the buyer is a senior citizen, defined in section 1689.5(f) as 65 or older. For a home improvement contract the period runs from receipt of a signed and dated copy of the contract. The CPUC states the same three-day and five-day windows in its consumer guide.
A referral request is optional and separate
California Rate Relief is a private solar referral service. It is not a contractor, it does not install or finance anything, and it does not review contracts or give legal or tax advice. Sending project details is a referral request: it does not approve anything, does not determine a price, a payment or a tax result, and does not establish that any provider is available for your address. The checklists on this page work whether or not you send anything.
