Solar leasing in California: what to know
Solar leasing can make rooftop solar more affordable upfront in California, but the details matter. Learn how leases and PPAs typically work, how net metering and utility rate changes can affect costs, and how to get matched with vetted local providers.
Solar leasing vs. PPA in California (the basics)
In California, many homeowners use a solar lease or a power purchase agreement (PPA) instead of paying for a system upfront.
With these agreements, the solar provider usually owns the equipment, and you either pay a monthly lease payment (lease) or buy the electricity the system produces at an agreed rate (PPA). Your monthly cost can be lower than your current electric bill, but savings aren’t guaranteed—they depend on your utility, your usage, and the contract terms.
A key point: the provider typically claims the federal Investment Tax Credit (ITC). That means you generally don’t receive the federal tax credit directly under a lease/PPA.
If you’re comparing options, start with these questions: What happens to your payment over time? Are there escalators (payment increases)? What are the terms for system repairs, roof issues, and contract transfers if you move? If you want guidance, you can also explore solar options: lease, PPA, and loan and then get matched with vetted local providers.
Net metering changes: why your utility bill may work differently
California’s solar compensation rules have changed over the years. Today, many homeowners receive bill credits based on how much electricity their system sends to the grid—often called net billing rather than the older net metering model.
Your benefit is still influenced by your utility’s program and rate design. For example, the value of exported solar power can depend on the time of day your solar produces electricity, and the utility may apply charges that affect your overall bill.
Because utility rules vary by utility service territory (and can change), your lease/PPA estimate should be based on your specific rate plan. Be cautious with “one-size-fits-all” quotes.
When you review an offer, ask for a clear, written example showing: your current average monthly electric bill, the proposed solar monthly payment, and how the bill credits are assumed over time. If the provider can’t show the math in plain numbers, that’s a red flag.
What “recent rate changes” can mean for leases and PPAs
California electric rates and charges can shift due to updates in utility planning and state programs. That matters because lease/PPA contracts often lock in the solar payment but not your utility charges.
Here’s a common pattern: even if your solar payment stays set for a period, your utility bill can change, and exported credits may be valued differently depending on the program. Some contracts include annual escalators for the lease/PPA payment. Escalators can make monthly payments rise over time.
So instead of asking only “Will I save money?” try asking: How much might my total monthly cost be in the first year, and in later years (for example year 5, year 10, and year 20)?

Contract terms to look for in California (read before you sign)
Lease/PPA contracts can be very different. In California, you’ll want to focus on the fine print—especially anything that affects price, term, and what happens if you move.
Consider asking for these details in writing:
- Payment escalator: How much does the lease/PPA payment increase each year?
- Term length: Common terms can be long; make sure you’re comfortable with the total commitment.
- Production assumptions: What system size (kW) and expected output does the provider assume?
- True-up or bill-credit assumptions: How does the agreement treat changes in net billing rules?
- Early termination and transfer: What if you sell your home?
- Maintenance and repairs: Who handles performance issues and roof-related impacts?
Also watch for high-pressure sales tactics. Some states regulate door-to-door or phone solicitation more heavily than others. If anyone asks you to sign immediately, ask for everything in writing and take time to review.
If you’re new to these contract types, you can learn the key differences in solar solutions. The most important step is to compare multiple proposals and never sign on the spot.
