Three years into her 20-year Sunrun solar lease, my client called with a simple question: how to get out of a Sunrun solar lease early. She was selling her house. The buyers didn't want to take over the lease. She needed a path.
"Transfer it or buy it out," I told her. "It's a standard process. You'll be fine."
That answer cost my company $4,200 in a service credit, cost her six weeks of delayed closing, and taught me a lesson I've since baked into every pre-install checklist we hand to new homeowners.
I build and service residential solar systems for a living. I've seen plenty of Sunrun solar panels — they're good equipment. The problem I'm about to walk through isn't the panels. It's the lease contract and what happens when you need to leave it early. I've been handling residential solar and storage orders for seven years, and I've personally made (and documented) four significant mistakes, totaling roughly $8,200 in wasted budget. This was the first one.
The surface problem: "I just want out of the lease"
Most homeowners think a solar lease exit works like canceling a subscription: you call, you pay a penalty, you're done. It doesn't work that way, and the gap between those expectations is where the money goes.
Everything I'd read about solar leases said transfers are easy when you sell your house. In practice, I've watched three out of ten prospective buyers walk away from a home when they heard "assume the solar lease." Some don't pass the credit check. Some don't want to inherit 17 years of payment obligations with annual escalators.
Put another way: getting out of a lease isn't a transaction. It's a negotiation with a company that has calculated its numbers very carefully.
The buyout math nobody explains upfront
My client asked for a buyout quote. I assured her it would be reasonable. They'd given me that advice in training: "The buyout is always an option." I didn't read the formula.
The quote came back at $19,800 for a 7.2 kW system that was three years old. Let me put that in context: 7,200 watts × $2.75 per watt (SEIA's average residential installed cost for Q2 2021) = $19,800. A brand-new system, same size, cost exactly what Sunrun was asking for three-year-old equipment. The three years of lease payments she'd already made — about $5,400 — counted for nothing in the buyout equation.
That's when I decoded the formula. The buyout is built from the remaining lease payments (discounted at roughly 6%), plus the federal tax credit Sunrun claimed, plus administrative costs. It's spelled out in the "Purchase Option" paragraph of the contract — buried around the middle. It's not designed to be a fair market price. It's designed to keep Sunrun whole.
They warned me about this in training, actually. "The lease buyout number won't make sense to clients in the first few years." I didn't internalize it until I saw a client's face when she read the quote. $4,200 and one incident log later, I understood.
The math only becomes reasonable around year five. That's when the Fair Market Value Purchase Option — it is in the contract, and almost nobody reads it — starts to apply. At year seven, I've seen buyouts priced at 35 to 45 percent of the original system cost. In the early years, buying out a lease is the most expensive way out.
What the exit actually costs
Here's the breakdown from my client's lease exit:
- $3,000 — the price reduction she accepted to get the third buyer to take the lease assumption
- $504 — four extra lease payments during the extended process
- ~$700 — duplicated utilities, mover rebooking, and storage fees
- 6 weeks — the delay between the expected close and the actual close
Total out-of-pocket: about $4,200. That doesn't include watching two offers fall apart because of a device on the roof.
A quick caveat: my experience draws from eight documented lease exit cases, all with Sunrun, mostly in California and Texas. If you're in another state, or signed a contract after 2022, your terms might differ. But the shape of the problem is the same.
The equipment restriction that made everything harder
Partway through the process, my client asked about adding a battery. Her realtor thought home storage would make the house easier to sell. We looked at the Tesla Powerwall 2 — a powerwall 2 battery life expectancy question comes up often, and the answer is solid: Tesla guarantees 70% capacity after 10 years, with 37.5 MWh of warranty throughput, and owners typically get 12–15 years.
But we couldn't add one to a leased system. The lease's equipment schedule is a fixed list: panels, inverter, monitoring. Third-party hardware counts as a "modification," which requires written approval. In practice, we'd have to renegotiate the lease just to attach a battery.
She didn't add the battery. The house sold without it, at a $3,000 concession.
I keep coming back to the same solar system sentence when explaining this to new clients: a solar system, in one sentence, is a 25-year energy partnership — and who owns it changes what it costs you.
What works instead: the lease exit checklist
After 2021, I built a checklist. My team has caught 47 potential lease issues with it over the past 18 months. Here's the short version — the same one I send every homeowner who signs a Sunrun lease through our office:
1. Call Sunrun's lease exit department first
Ask for a written payoff statement and your amortization schedule. Not general customer service — the lease exit team. The statement doesn't obligate you to anything; it just gives you the actual number.
2. Find the Fair Market Value Purchase Option
If you're past year five, this can drop the buyout substantially. If Sunrun's quote seems high, ask explicitly for the FMV calculation. I've negotiated buyout quotes down by as much as $2,000 with that one sentence.
3. If selling: pre-qualify buyers early
Start the transfer application before you list the house. Have buyers complete Sunrun's credit pre-check as part of their offer. This filters out the DTI failures that cost my client six weeks.
4. Ask about relocation
Sunrun doesn't advertise this, but leases can sometimes move with you within their service area. I've seen it approved for homeowners moving in-state. Not guaranteed, but worth one phone call.
5. Compare the buyout price to a new system install
Get both numbers side by side. If the lease isn't past its midpoint, a new system is usually the better economic choice. Past year seven, the buyout can make sense — and ownership gives you the right to modify the system.
6. The DIY option after ownership
One client who bought out at year seven built a workshop battery backup from surplus panels. For reference, how many watts can a 50 amp charge controller handle? Roughly 720W on a 12V system, about 1,440W on 24V, and up to 2,880W on 48V. His whole setup cost about $700. That flexibility only comes with ownership.
The bottom line
Getting out of a Sunrun solar lease early is possible. It's a process, not a phone call — and the economics shift dramatically after year five. If you're in the early years, the transfer route is usually your best exit. If you're past year seven, the buyout starts to look fair.
The most efficient thing you can do is exactly what I didn't do in March 2021: get the payoff statement, read the purchase option paragraph, and make the decision based on the actual numbers. Not on a confident guess from someone who says they "know the drill."
That lesson is now the first page of our pre-install packet. I still wish I hadn't needed to learn it the hard way — but at least the $4,200 wasn't entirely wasted.
