If you’re shopping for residential solar, Sunrun will come up in almost every conversation. They’re the largest dedicated residential solar company in the United States, with over a million customers and installations across 22+ states. But size doesn’t always equal quality, and a company that big serves a lot of different types of homeowners with very different experiences.
I went through the Sunrun process in 2023 — got quotes, sat through the sales presentation, and ultimately used their service to compare against other installers before making my final decision. This review covers what I learned, what current customers say, and when Sunrun is (and isn’t) the right fit.
Quick Verdict
Sunrun is a solid choice for homeowners who want a hands-off solar experience and are comfortable with a long-term lease or PPA rather than ownership. Their BrightSave lease program simplifies the decision: you get solar with $0 down, Sunrun owns the panels and handles maintenance, and you pay a lower monthly rate than your current utility bill.
The tradeoff is that you don’t own the asset, which complicates home sales and eliminates direct access to the federal tax credit. For homeowners who want to own outright, Sunrun offers purchase options too, but you’ll find more competitive pricing by getting multiple quotes from local installers.

What Sunrun Offers
BrightSave Lease
This is Sunrun’s flagship product. You pay $0 upfront, Sunrun installs the panels, and you pay a fixed monthly rate for 25 years. Sunrun owns the equipment, handles all repairs and maintenance, and guarantees system performance.
The appeal is obvious: no capital outlay, no worrying about panel degradation or inverter failures, and predictable energy costs. The downside: you can’t claim the 30% federal solar tax credit (Sunrun takes that), and when you sell your home, the new buyer has to either take over the lease or you pay a buyout.
BrightSave Monthly (PPA)
Similar to the lease, but instead of a fixed monthly payment, you pay per kilowatt-hour for the electricity your panels produce. The rate is typically lower than your utility’s retail rate, with annual escalators of 0-2.9% depending on your contract. Sunrun still owns the system.
BrightAdvantage (Loan)
Sunrun’s solar loan lets you finance the purchase and own the system from day one. You claim the federal tax credit directly. Interest rates and terms vary; compare against credit unions and third-party solar lenders for the most competitive rates.
Brightbox Battery Storage
Sunrun’s home battery option keeps essential loads running during outages and can optimize for time-of-use rates. If backup power is a priority, compare Brightbox against the Tesla Powerwall and other standalone storage systems before committing.
Sunrun Pricing: What to Expect
Sunrun doesn’t publish prices online — system cost depends on your home’s size, roof type, local utility rates, and available incentives.
- Lease/PPA: $0 down. Monthly payments typically range from $80 to $200 depending on system size and location. Most customers save 10 to 30% versus their current electric bill from day one.
- Cash/loan purchase: National average is around $2.80 to $3.50 per watt before incentives. A 7kW system might run $19,000 to $24,500 before the 30% federal tax credit, bringing net cost to roughly $13,000 to $17,000.
The most reliable way to know what you’ll actually pay is to get competing quotes. Use a marketplace like EnergySage to receive multiple installer bids for your specific home — in most markets you’ll see three to five quotes, letting you compare price and product side by side.
Installation Process and Timeline
Sunrun’s installation timeline runs 2 to 4 months from contract to permission-to-operate, which is in line with the industry average.
- Site assessment: A Sunrun rep evaluates your roof, electric panel, shading, and energy usage.
- System design: Custom design based on your usage history and goals.
- Permits and HOA approval: Sunrun handles permit filing. This is usually the longest step — can take 4 to 8 weeks alone in some municipalities.
- Installation day: Most standard residential installs take one day on the roof.
- Utility inspection and PTO: Your utility inspects and grants Permission to Operate. Once approved, the system is live.
Customer experiences vary significantly by market. In states with high Sunrun volume — California, Arizona, Florida, Massachusetts — reviews trend more positive. In newer markets, timeline delays are more common.
What Real Customers Say
Sunrun has mixed reviews across platforms, which is common for large installers handling hundreds of thousands of projects:
- Trustpilot: Approximately 3.8 out of 5 (7,000+ reviews)
- ConsumerAffairs: Approximately 3.5 out of 5
- Google Reviews: Varies by local branch, 3.5 to 4.5 out of 5
- BBB: B rating with active complaint resolution
Positive reviews consistently mention smooth installations when everything goes as planned, responsive warranty service, and genuine electricity bill savings on lease agreements. Negative reviews commonly cite long permitting delays (4 to 6 months in some cases), difficulty reaching customer service post-install, confusion about lease transfers during home sales, and aggressive door-to-door sales tactics in certain areas.
Sunrun vs. Competitors
Before committing to Sunrun, it’s worth understanding how they compare to other options in your market:
- Tesla Solar: Online pricing transparency, purchase-only (no leases), Powerwall integration. Better for buyers who want ownership clarity and technology integration with home energy systems.
- SunPower/Complete Solaria: Higher-efficiency panels available in 50 states. More expensive per watt but strong long-term ROI for high-energy-use homes.
- Local installers: Often 10 to 20% cheaper than national companies for the same hardware. Less brand recognition but frequently better customer service and faster permitting in familiar jurisdictions. EnergySage vets their network installers.
Is the Sunrun Lease a Good Deal?
The honest answer: it depends on your state’s electricity rates and how long you plan to stay in your home.
In California, Massachusetts, Connecticut, and Hawaii, electricity is expensive enough that even after Sunrun’s margin, you still come out ahead on monthly savings. In lower-rate states, the savings are thinner and ownership often makes more financial sense.
The bigger issue is the 25-year term. If you sell your home in year 8, you’ll either need a buyer who qualifies to assume the lease or pay a buyout fee to cancel. Both scenarios add friction to a home sale — this is the single most common complaint in Sunrun’s negative reviews.
How to Get the Best Solar Quote
The biggest mistake homeowners make with solar is talking to only one company. Before committing to Sunrun (or anyone else), take these steps:
- Use EnergySage to get three to five competing quotes for your home. It’s free and shows side-by-side comparisons of system size, panel brand, price per watt, and estimated savings.
- Understand whether you’re being offered a lease, PPA, loan, or cash purchase — these are fundamentally different financial products with different long-term implications.
- Ask about the annual escalator on any lease or PPA — what does your payment look like in years 10 and 20?
- Verify the installer’s license and insurance independently through your state solar association.
Final Verdict
Sunrun is a legitimate, experienced solar company with an industry-leading 25-year workmanship warranty. For homeowners who want zero upfront cost, no maintenance responsibility, and a long-term lease commitment they’re comfortable with, Sunrun delivers.
But “legitimate” doesn’t mean “best price.” Sunrun operates at scale with a large national sales force, and those costs are in your contract. Getting multiple quotes before you sign is the single most valuable step you can take — whether that ends up being Sunrun or a local installer who can match their service at a lower cost.
