How Sunrun Works and What to Know Before You Choose Them

What Sunrun does and how it differs from other solar companies

Sunrun is a solar installation and financing company that installs rooftop solar systems and lets you pay for them over time rather than upfront. Unlike some solar installers who only build the system and leave, Sunrun typically owns or finances the panels and handles maintenance for the life of the contract—usually 20 to 25 years. That means you pay a monthly bill to Sunrun instead of to your utility company, or you pay a lower bill split between Sunrun and the utility.

The company operates in most U.S. states and has installed systems on hundreds of thousands of homes. Sunrun's main business model is the solar lease or power purchase agreement (PPA)—you don't own the panels, but you own the electricity they produce (or in a lease, you simply pay a fixed monthly rate). A smaller portion of Sunrun's business is selling systems outright, which you would own and finance through a loan.

What sets Sunrun apart from local installers is scale and financing options. A local installer might require you to get your own loan or pay cash. Sunrun brings its own financing to the table, which can mean faster approval and no money down. The tradeoff is that you're locked into a long contract with one company, and you won't own the equipment.

Key Takeaways

• Sunrun installs solar panels and finances them through leases or power purchase agreements, so you typically pay no money upfront.
• You do not own the panels under a lease or PPA; Sunrun owns them and handles repairs and maintenance for the contract term.
• Your monthly payment depends on your current electricity usage, local utility rates, and the size of the system Sunrun designs for your roof.
• Sunrun's contracts usually run 20 to 25 years, and you cannot easily exit early without paying a penalty or transferring the contract to a new homeowner.
• The company offers a monitoring app so you can track how much electricity your system produces each day.

How Sunrun's lease and power purchase agreement work

In a solar lease, you pay Sunrun a fixed monthly fee—typically $100 to $300, depending on system size and your region—and Sunrun owns the panels. You get all the electricity the system produces, and Sunrun handles all maintenance, repairs, and equipment replacement if something fails. Your bill does not change year to year, which makes budgeting predictable.

In a power purchase agreement (PPA), you pay Sunrun only for the electricity the panels generate, not a flat fee. If your system produces 500 kilowatt-hours in a month and Sunrun charges $0.12 per kilowatt-hour, you pay $60 that month. If it's cloudy and production drops, your bill drops too. PPAs often include an annual price increase of 2 to 3 percent, so your bill will rise slightly each year even though the rate per kilowatt-hour stays the same.

Both structures mean Sunrun keeps the federal tax credit (currently 30 percent of installation cost) and any state or local rebates. You do not claim these on your taxes. Sunrun passes some of the savings to you through a lower monthly payment, but the company keeps the majority of the tax benefit.

What happens during the Sunrun installation process

Sunrun's process typically starts with an online quote or a phone call. You provide your address and recent electricity bills, and Sunrun's system estimates how much solar you need and what your monthly payment would be. If you move forward, a Sunrun representative schedules a site visit to inspect your roof, measure its angle and direction, and check for shade from trees or nearby buildings.

Once the design is finalized, Sunrun handles permitting with your local government and coordinates with your utility company to set up the interconnection—the technical connection between your system and the grid. This step can take weeks depending on your area. Sunrun also arranges financing and sends you documents to sign, including the lease or PPA contract.

Installation itself usually takes one to three days. Sunrun's crews mount the panels, install the inverter (which converts DC power to AC power for your home), run wiring, and set up monitoring. After installation, a city or county inspector must approve the system before it can turn on. Once approved, your system goes live and you begin producing electricity.

Costs, savings, and what your monthly payment includes

Sunrun advertises "no money down," which is accurate for leases and PPAs—you do not pay an installation cost upfront. Your monthly payment covers the cost of the panels, installation, financing, maintenance, insurance, and Sunrun's profit. A typical monthly payment ranges from $100 to $300, though this varies widely based on your roof size, local electricity rates, and how much sun your location receives.

To estimate your savings, compare your current electricity bill to what Sunrun quotes. If you pay $150 a month to your utility and Sunrun quotes $120 a month, you save $30 monthly—or $360 a year. Over a 25-year contract, that's $9,000 in savings, though the actual number depends on whether electricity rates rise (which they usually do) and whether Sunrun's rates increase under the PPA terms.

Sunrun's monthly payment includes maintenance and repairs. If an inverter fails or a panel stops working, Sunrun replaces it at no cost to you. You are responsible for keeping the roof clear of debris and allowing Sunrun access for inspections, but you do not pay for service calls or parts.

Transferring a Sunrun contract when you sell your home

If you sell your house before the contract ends, the new owner can take over your Sunrun agreement. Sunrun handles the paperwork, and the buyer assumes your monthly payments and contract terms. Some buyers see this as a selling point—a home with an existing solar system and a fixed electricity rate. Others view it as a liability and may ask you to pay down the contract or negotiate a lower home price to offset it.

If the new owner does not want to assume the contract, you have two options: pay Sunrun a buyout fee (usually several thousand dollars) to end the agreement, or leave the contract in place and continue paying Sunrun even after you move. The buyout amount is spelled out in your contract and typically represents the remaining value of the system.

This transfer requirement is one reason some homeowners prefer to own their panels outright—ownership transfers automatically with the home and requires no special paperwork or negotiation.

Sunrun's warranty, monitoring, and customer service

Sunrun warrants that panels will produce at least 80 percent of their rated output after 25 years, which is standard in the industry. The inverter usually carries a 10-year warranty, and Sunrun covers labor for repairs under the lease or PPA. If you own the system outright, you would need to purchase a separate service plan or pay out of pocket for repairs after the manufacturer warranty expires.

Sunrun provides a mobile app and online dashboard where you can monitor your system's daily and monthly electricity production. You can see how weather affects output and compare your production to similar systems in your area. The app also alerts you if the system stops producing, which can help you catch problems early.

Customer service is available by phone and online chat. Response times and satisfaction ratings vary by region. Some customers report quick resolutions; others describe long hold times or difficulty reaching someone who can help. Before signing, check recent reviews specific to your state or service area.

Comparing Sunrun to other solar installation options

Sunrun is one of the largest solar companies in the country, but it is not the only option. Local installers may offer lower prices or more customized designs, though they typically require you to arrange your own financing. Other national companies like Vivint Solar (now owned by Sunrun), Tesla Energy, and regional providers offer similar lease and PPA models.

If you want to own your panels outright, you can buy through Sunrun, a local installer, or a manufacturer directly. Ownership means you claim the federal tax credit and any state rebates, and you own the system after the loan is paid off—usually in 7 to 10 years. Ownership also means you pay for repairs after the warranty ends and you are responsible if something goes wrong.

The choice between Sunrun and alternatives depends on whether you value simplicity and predictability (Sunrun's lease or PPA) or long-term ownership and tax benefits (buying outright). Getting quotes from at least two or three companies—including a local installer—helps you compare costs and terms.

Frequently Asked Questions

Can I cancel a Sunrun contract early?

You can cancel by paying a buyout fee, which is typically several thousand dollars and represents the remaining value of the system. The exact amount is in your contract. You cannot simply walk away without paying. If you sell your home, the new owner can assume the contract instead of you paying the buyout.

What if my roof needs repairs or replacement during the contract?

Sunrun will remove the panels, you pay for the roof repair, and Sunrun reinstalls the panels once the work is done. If the roof is under warranty or covered by homeowners insurance, those may cover the cost. Discuss roof condition with Sunrun before signing so you understand who pays if work is needed soon.

Do I still get a utility bill if I have Sunrun?

Yes. Your system produces electricity during the day, but you still draw power from the grid at night and on cloudy days. You receive a bill from your utility for the power you use beyond what your panels produce. Sunrun's payment is separate from your utility bill.

What happens if my electricity usage increases?

Under a lease, your monthly payment stays the same regardless of how much electricity you use—you just draw more from the grid and pay your utility for it. Under a PPA, you pay Sunrun only for what the panels produce, so increased usage does not affect your Sunrun bill, only your utility bill.

Is Sunrun available in my state?

Sunrun operates in most U.S. states, but not all. The easiest way to check is to enter your address on Sunrun's website. Some states have restrictions on solar leases or PPAs, so availability depends on both Sunrun's service area and your state's regulations.
