How does Sunrun solar work?
Sunrun sells solar four ways, and its signature product is the lease and the PPA. With a lease you pay a fixed monthly payment to use a system Sunrun owns and installs on your roof; with a PPA you pay a set rate per kWh for the power it produces. Both are $0 down, run 20 to 25 years, and usually include an annual escalator (often around 1% to 3.5%) that raises your payment each year. Sunrun owns the hardware, so it handles maintenance, monitoring, and repairs for the life of the contract, and it backs that with a performance guarantee. The other two paths, a solar loan and a cash purchase, mean you own the system outright.
Sunrun is the biggest player in US home solar, with well over a million customers, and it got there partly by acquiring Vivint Solar in 2020. It installs standard third-party panels rather than making its own, pairs them with battery storage (including the Tesla Powerwall and its own storage), and sells through both its own teams and a network of dealers, which is why a lot of Sunrun sign-ups start with a door-to-door or phone pitch. Being the largest installer is a genuine plus for warranty service: a company that size is likely to still be around in year 15 when you need a panel replaced.
How much does Sunrun solar cost?
The honest answer is that a Sunrun lease or PPA costs $0 upfront, and the real number to judge is the monthly payment against your current utility bill. If Sunrun quotes a payment meaningfully below what you pay the utility now, and the escalator is low, the lease can lower your bill from day one with no cash out of pocket. If the payment is close to your utility cost, or the escalator is steep, the savings can thin out or disappear over the 20 to 25 years. There is no single sticker price to quote, because a lease is priced on your roof, your usage, and your local rate, not on dollars per watt.
A Sunrun purchase or loan is quote-based like any installer, and it tends to land near or a bit above the national average of about $3.00 to $3.50 per watt installed. Convert every quote you get, from Sunrun or anyone else, to dollars per watt so you can compare them fairly, and read the full cost guide for what drives the total. Then run your own usage and rate through the solar panel calculator. Every figure here is an estimate, not a quote for your home; see the disclaimer.
What is the downside of Sunrun?
The main downside is that a lease or PPA means you do not own your system, so you build no equity in it and you cannot claim any tax credit or incentive yourself. You are buying cheaper power, not an asset. The contract is long, 20 to 25 years, and the annual escalator can push your payment up faster than your utility raises rates, which is the scenario where a lease quietly stops saving you money. Because Sunrun keeps the incentives and the ownership, a lease almost always delivers less lifetime savings than buying the same system, whether from Sunrun or another installer.
The other friction shows up when you sell your house. A buyer has to either assume the remaining lease (and qualify for it) or you have to buy the contract out, and that can slow or complicate a sale. Sunrun's sales channel is a common complaint too: a lot of the pitches come from third-party door-to-door dealers, and high-pressure tactics and promises that are not in the contract are exactly what reviews warn about. None of this makes Sunrun a bad company, but it does mean the paperwork deserves a careful read. Weigh the whole tradeoff in solar lease vs buy and the pros and cons of home solar.
Is there a tax credit for a Sunrun system in 2026?
Not for you directly, and this is the single most important 2026 update. The 30% federal residential solar tax credit (Section 25D) expired after December 31, 2025, so if you buy any system now, Sunrun or otherwise, you get no federal residential credit. Ignore any Sunrun quote, or any solar review, that still bakes a 30% homeowner credit into the savings math; that number is out of date.
The wrinkle with a lease or PPA is that Sunrun owns the system, not you, so the credit that still exists flows to the owner, not to you. Under current rules a third-party-owned system can reach the commercial clean-energy credit (48E), available through 2027, claimed by the system owner. That is part of why Sunrun can still offer $0-down solar that pencils out. It does not put a check in your pocket; at most it helps Sunrun price the lease. State rebates, utility programs, and net metering rules still vary widely and are where your real incentives now come from, so verify current programs for your address before you count on any number.
Sunrun lease vs buy: which saves more?
If you can afford it, buying saves more than leasing, full stop. When you own the system (cash, or a solar loan, from Sunrun or a competitor) you keep all the production value and any incentives the owner can claim, and after the loan is paid the power is effectively free for the rest of the panels' 25-plus year life. A lease trades that larger long-term win for no upfront cost and zero maintenance worry, because Sunrun carries the ownership and the repairs. Over 25 years, owning typically comes out thousands of dollars ahead.
A Sunrun lease still makes sense in specific cases: you have little or no cash for a down payment and cannot get a good loan, you do not want to deal with maintenance or a broken inverter, or you are in a high-rate, outage-prone market (California is the classic example) where any bill reduction helps and a bundled battery adds real value. A battery is a separate decision either way; size it with solar batteries explained. The full lease-versus-own math, including the resale angle, is laid out in solar lease vs buy.
Is Sunrun worth it in 2026?
Sunrun is worth it for a specific buyer: someone who wants $0-down, hands-off solar, cannot or would rather not pay cash, and lives where electricity is expensive and outages are common. In that case a lease or PPA can cut your bill immediately with no maintenance headaches, backed by the largest installer in the country. Its size and its performance guarantee are real advantages for long-term service, and bundling a battery through Sunrun is a clean way to get backup power.
It is a weaker choice if you can pay cash or qualify for a solar loan, because owning the system almost always beats the lease on lifetime savings, or if you are uneasy about a 20 to 25 year contract with an escalator and a sales process that leans on third-party dealers. As with any installer, get at least three quotes, put every one in dollars per watt, read the contract line by line (especially the escalator and the home-sale transfer terms), and model your own case in the solar panel calculator. If you specifically want to own for the lowest sticker price, compare against a purchase-only option like Tesla solar. These are estimates, not financial advice.
Frequently asked questions
Is Sunrun a good choice for solar?
For a buyer who wants $0-down, hands-off solar and lives where power is expensive, yes, Sunrun is a reasonable choice: it is the largest US installer, it maintains the system for the contract term, and it backs a performance guarantee. It is a weaker choice if you can pay cash or get a solar loan, because owning the same system almost always saves more over 25 years than leasing it. Get three quotes, compare dollars per watt, and read the lease before deciding.
What is the downside of Sunrun?
The biggest downside is that most Sunrun deals are 20 to 25 year leases or PPAs, so you do not own the system, you cannot claim incentives, and an annual escalator can raise your payment over time. Because Sunrun keeps the ownership and the tax credit, a lease usually saves less over the system's life than buying it would. Selling your home means a buyer has to assume the lease or you buy it out, and many sign-ups come through third-party door-to-door dealers, which is where high-pressure sales complaints come from.
Why is Sunrun being sued?
Large solar-lease companies, Sunrun included, have faced consumer lawsuits, regulator complaints, and customer disputes, most often over door-to-door sales claims and lease terms that buyers say were not clearly explained, along with the shareholder suits that tend to follow any public company's stock swings. Specific cases and their outcomes change over time, so check current, reputable sources rather than one review site. The practical lesson is not that Sunrun is uniquely bad; it is that a 20 to 25 year contract deserves a careful read, and you should get every salesperson promise in writing.
Who is the most reputable solar panel company?
There is no single most reputable company, because home solar is mostly local and the installer who wires your roof matters more than the brand on the panels. Among national names, Sunrun is the largest and Tesla often has the lowest published purchase price, while the best-reviewed installers are usually strong regional companies with long local track records. Judge any company by its warranty, its dollars-per-watt price, verified customer reviews in your state, and whether it will still be around to service the system. Get at least three quotes before you decide.
What happens to a Sunrun lease when you sell your house?
You generally have a few options: transfer the lease or PPA to the buyer (who must qualify and agree to take it over), prepay or buy out the remaining contract, or in some cases have the system relocated. A transferable lease is common, but it can still slow a sale if a buyer does not want to inherit a 15-plus year contract, and a buyout can be costly. Read the transfer and buyout terms before you sign, since they are a known friction point with any leased solar system.
