Yes, a solar payment increase is normal. Many solar leases and PPAs include an escalator that raises the payment every year, usually by 1.99% to 2.9%. Normal doesn't automatically mean it's a good deal, though. It comes down to two numbers: how much lower the escalating payment starts, and how long you'll stay in the house. Short stays usually favor the escalator. Long stays usually favor a flat rate, or owning the system outright.
Here's an example, a simple way to tell which side of the line you're on, and how each financing option compares. New to escalators? Start with how a solar escalator works.
What a solar payment increase really is: the escalator clause
A solar payment increase comes from one line in your solar contract: the escalator clause. It raises your monthly payment, or your price per kilowatt-hour with a PPA, by a set percentage every year. A 2.9% annual escalator is the most common, though rates run from 0% to about 3.5%.
Solar companies build escalators in because they let the starting payment look lower. The company that owns your solar equipment still collects what it needs over 20 to 25 years. Here's more on why some solar leases have escalators in the first place.
Escalator vs. no escalator: your solar lease and solar PPA options
Most leases and PPAs come in two versions. One starts lower and goes up every year. The other starts higher and never changes. Same solar panels, same solar inverter, same roof. The only difference is the shape of your payment amounts over time.
- Escalating solar lease or PPA: a lower payment in year one, then an annual increase for the life of the contract.
- Flat solar lease or PPA: a fixed monthly payment that starts higher and stays put.
With a PPA or lease, the solar provider owns the entire solar system, so monitoring and repairs after the solar installation are usually theirs to handle. Here's how a solar lease and a PPA differ in more detail.
Example: the total cost of $150 rising 2.9% vs. $185 flat
Here's what each one costs over time:
| Total paid after | $150 at 2.9% | $185 flat | Lower total cost |
|---|---|---|---|
| 5 years | $9,537 | $11,100 | Escalator, by $1,563 |
| 10 years | $20,540 | $22,200 | Escalator, by $1,660 |
| 15 years | $33,234 | $33,300 | Escalator, by $66 |
| 20 years | $47,878 | $44,400 | Flat, by $3,478 |
| 25 years | $64,772 | $55,500 | Flat, by $9,272 |
Example starting payments for illustration. Your quotes will differ, so run your own numbers.
The escalating payment starts $35 a month cheaper. It passes $185 in year 9, and its running total passes the flat option in year 16. Stay all 25 years and the total amount you'd pay is about $9,272 more with the escalator. Here's the full year-by-year math on a 2.9% solar escalator.

Run my numbersHow your escalator rate stacks up against utility rates
An escalator is a bet that your local utility will raise prices faster than your solar payment rises. Massachusetts electricity rates have climbed a lot over the past decade, but they don't go up every year, and some years they fall. Your escalator rate only goes one direction.
Compare your solar price against the electricity rate you actually pay, not a national average. Here's how solar lease escalators compare with Massachusetts utility rates, including the year an escalating payment can catch up.
When a payment increase works for a homeowner
- You expect to move within 10 years or so.
- The flat option starts a lot higher, not just a few dollars.
- A lower monthly payment right now matters more to your budget than the total over 25 years.
When no escalator wins on your electric bill
- You plan to stay for most of the life of the system.
- The flat option is only a little higher at the start.
- You might be selling your home someday. A fixed payment is easier for a buyer to take over, because it doesn't keep climbing. Some home sales include a solar energy system that's already leased, and buyers look hard at whether that payment escalates.
Either way, most homes still get a small electric bill, since net metering credits don't always cover every month. Here's why you'll still have an electric bill with solar.
Leasing solar vs. owning a solar system: financing options with no escalator
There are three common ways to go solar. Only two can include an escalator:
- Solar lease: no upfront cost, a fixed monthly payment that may rise each year, and the company owns the solar energy system.
- Solar PPA (power purchase agreement): no upfront cost, and you pay per kilowatt-hour for the electricity produced, often with an annual increase.
- Owned solar: a cash purchase or a solar loan. There's no escalator, and the electricity generated by a solar system you own is yours.
Lease vs. purchase: what changes
When you purchase a solar system, the upfront cost or loan payment replaces the escalating lease payment. A loan payment is a fixed payment, so it never climbs. Purchasing your solar system also means you own the equipment, the inverter and the warranties, and every kilowatt-hour the system produces is yours. Owned solar can also add to your home's market value, while a leased residential solar PV system usually doesn't. The right solar solution and solar financing depend on your budget, system size and how long you'll stay. When you have more than one offer, here's how to compare two solar quotes with different escalators.
Incentives, the tax credit and your solar panel deal
The federal tax credit for homeowners who buy their own system ended on December 31, 2025. That shifted the math between a cash purchase or a solar loan and a lease vs. PPA, so older quotes and online calculators may be out of date.
Massachusetts solar incentives are still worth asking about, like the SMART program and net metering. With leases and PPAs, the system owner usually receives the SMART incentive, while net metering credits typically show up on your own electric bill. Ask any solar provider to spell out which incentive goes to whom.
The benefits of solar energy with a flat payment
The benefits of solar don't depend on the escalator. Solar power gives you clean energy from your own roof, renewable energy you don't buy from the grid, and a hedge against rising electricity costs. A flat payment just makes those savings easier to predict, because the payment never changes while utility prices move around.
Many solar customers never ask for the 0% option, even though plenty of residential solar projects offer one. If you're comparing offers, a local solar consultant can line them up side by side for you.
How to ask a solar provider for a 0% option
Many solar companies offer a flat option even if it isn't the first number they show you. Ask for every escalator option on the same system, in writing, and compare the total cost, not just the first payment. Also ask whether the contract lets you buy out the remaining payments later, and what that buyout would cost. Before you sign, here's what to look for in a solar contract.

Mark, review my quoteFAQs About Solar Payment Increases
Does my solar payment go up every year?
Only if your contract has an escalator. With an annual escalator, the payment rises by the same percentage on a set date each year. With a 0% option, or if you own the system, it stays the same.
How much higher does a 0% option usually start?
It depends on the solar provider and the system size. The only way to know is to ask for both options on the same system and compare the starting payments side by side.
Can I switch to a flat payment after I sign?
Usually not. The escalator clause is part of the contract. That's why it's worth deciding before you sign, while you can still pick a different option.
