Sunrun review
The largest residential solar company in the United States. Sunrun's scale brings nationwide service, flexible $0-down financing, and long-term system maintenance — at a price that runs higher than local value installers.
Sunrun is our pick for homeowners who want a big, established national brand and financing flexibility. As the largest residential installer in the U.S., it offers something most local shops can't: lease and power-purchase-agreement plans that put solar on your roof for $0 down, plus a nationwide service network and long-term maintenance on financed systems. The honest trade-off is price — a Sunrun purchase runs higher per watt than a local value installer, and its lease/PPA plans mean you don't own the system. If you value convenience, financing options, and brand stability over the lowest possible price, Sunrun is a strong, safe choice.
Sunrun at a glance
Who they are
Founded in 2007 and headquartered in San Francisco, Sunrun is the largest dedicated residential solar company in the United States. It is publicly traded (NASDAQ: RUN) and has installed solar for hundreds of thousands of homes across the country — a scale no local installer can match. For Dallas–Fort Worth homeowners, that scale is the whole story: it shapes how Sunrun prices, finances, installs, and services a system.
Sunrun built its business on a simple idea that reshaped the industry: instead of asking homeowners to pay tens of thousands of dollars up front, it would own the solar system and sell the power. That is the essence of its lease and power-purchase-agreement (PPA) model, and it's the reason Sunrun grew so fast. Over time the company added loan and cash-purchase options too, so today it can meet a homeowner wherever they are financially — from $0 down to full ownership.
The company operates through a mix of its own crews and vetted local installation partners, depending on the market. In practice, that means the salesperson, the design team, and the crew on your roof may be different groups coordinated under the Sunrun brand. The upside is consistency of process and a company big enough to still be around in 20 years to honor a warranty; the trade-off is that the experience can feel less personal than a small local shop where the owner walks your roof.
It's worth being clear-eyed about Sunrun's position. Because it competes on financing, brand, and service rather than the lowest sticker price, it is rarely the cheapest quote a DFW homeowner receives. What it offers instead is optionality and stability: the ability to go solar with no money down, a nationwide support footprint, and the reassurance of the biggest name in the business standing behind the system.

Equipment & warranty
Because Sunrun operates at national scale, it isn't tied to a single panel or inverter brand the way some boutique installers are. Instead, it sources Tier-1 equipment and matches components to each market and roof. Here's what to expect and how the coverage works.
Panels
Mainstream Tier-1 modules (brands vary by market). Efficient, well-warrantied monocrystalline panels rather than premium designer brands.
Inverters
Typically microinverters or string inverters with optimizers, giving panel-level performance and monitoring on most installs.
Storage
Sunrun's own battery plus compatible third-party options for whole-home or essentials backup.
The warranty structure depends on how you pay, and this is one of the most important things to understand about Sunrun:
- Lease / PPA: Sunrun owns the system and covers it bumper-to-bumper for the life of the agreement — usually 20–25 years — including monitoring, repairs, and equipment replacement. If a part fails, it's their problem, not yours.
- Purchase (cash or loan): You get the manufacturers' warranties on the panels (typically 25 years), inverter (often 12–25 years), and battery (usually 10 years), plus Sunrun's own workmanship warranty on the installation.
- Production guarantee: Many Sunrun plans include a guarantee that the system will produce a specified amount of energy, with compensation if it falls short.
The lease warranty is a real advantage
On a leased or PPA system, you never pay for a repair, an inverter swap, or monitoring — Sunrun handles it for 20–25 years because they own the equipment. For homeowners who don't want to think about maintenance, that hands-off coverage is genuinely valuable, even though you give up ownership to get it.
Pricing & financing
Sunrun's defining feature is that it offers every major way to pay for solar — and the right one changes your cost and ownership picture entirely. Here's how the four paths compare.
| Option | Upfront | You own it? | Best for |
|---|---|---|---|
| Lease | $0 down | No | No cash outlay, hands-off maintenance |
| PPA | $0 down | No | Paying only for power produced |
| Solar loan | $0–low down | Yes | Owning with monthly payments |
| Cash purchase | Full price | Yes | Lowest lifetime cost |
For a cash or loan purchase, expect Sunrun to land around $3.50–$4.00 per watt in the Dallas area — noticeably higher than local value installers that sit near $2.75/W. You're paying a premium for the brand, the nationwide service network, and the financing infrastructure.
With a lease or PPA, there's no per-watt sticker at all. Instead you pay either a fixed monthly amount (lease) or a set rate per kilowatt-hour the system generates (PPA), typically with an annual escalator that raises the payment a small percentage each year. The appeal is obvious — $0 down and immediate savings versus your utility bill — but read the escalator and contract term carefully, because over 20–25 years a leased system usually costs more in total than owning one outright.
The ownership trade-off in one line
If your top priority is the lowest lifetime cost, buy the system (from Sunrun or, often cheaper, a local installer). If your top priority is no upfront cost and zero maintenance, Sunrun's lease or PPA is one of the most established ways to get there. Our guide to paying for solar breaks down the math on each path.
What to expect: the install process
A Sunrun installation follows the same broad arc as any solar project, but the national-scale process is worth walking through so you know what you're signing up for.
- Consultation & quote. A Sunrun advisor reviews your energy usage, roof, and goals — often remotely using satellite imagery — and presents your financing options (lease, PPA, loan, or cash).
- Custom design & agreement. Sunrun's design team produces a system layout, production estimate, and pricing. You sign the agreement that matches your chosen payment path.
- Site survey & permitting. A technician verifies your roof, electrical panel, and measurements, then Sunrun pulls city permits and files the utility interconnection application on your behalf.
- Installation. A Sunrun crew or local installation partner mounts the racking, panels, inverter, and any battery — usually completed in one to three days.
- Inspection & permission to operate. The city inspects the system and the utility grants Permission to Operate (PTO). Your system switches on, and monitoring begins.
Start to finish, budget roughly 6–12 weeks. The install day itself is fast; permitting and utility approval are what take the most time — and that's true of every installer, not just Sunrun.

Who Sunrun is best for
Sunrun isn't the right answer for everyone, and a trustworthy guide should say so plainly.
Choose Sunrun if…
You want $0 down, prefer a hands-off leased system with maintenance included, value a big national brand's stability, or want financing flexibility to compare lease, loan, and cash side by side.
Look elsewhere if…
Your #1 goal is the lowest total cost (a local value installer usually wins), you want to own the system and claim its full value yourself, or you prefer a hyper-local shop where the owner is on your roof.
