Is subscription solar worth it?
By Jake Breaux, solar industry expert · Updated
The short version
The answer turns on one question, and it isn't price: how long are you keeping the house. Plan to stay twenty years and you want to own the panels, buying usually beats subscribing on lifetime cost. Three to fifteen years, or genuinely unsure, and the subscription is the better shape: nothing down, no lien on the property, repairs and insurance carried by the provider, and a commitment that stops at 36 months inside a ten-year agreement.
Who should not subscribe to solar?
Start with the no, because it's the shorter list. If you can pay cash and you're confident you're staying in the house for twenty years, ownership usually wins on lifetime cost. If the roof needs replacing, do the roof first. Heavy shade, a credit file under about 650, renting, a condo, panels already up there, or a budget that no new monthly bill fits: all noes.
That list costs us deals every month. We lead with it anyway, because the alternative is selling a subscription to somebody who needed a roofer, and that phone call comes back eighteen months later with interest. The product fits a specific person. Anybody telling you it fits everyone hasn't asked you enough questions yet.
Is subscription solar worth it?
It turns on how long you plan to own the house, more than on any number in the quote. If the answer is three to fifteen years, or you honestly don't know, a subscription is usually worth it: nothing down, no lien on your title, and somebody else paying for the repairs. If you're certain you're staying twenty five years and you want the asset, buy it and hold the cost floor.
The old advice had this backwards. Sellers used to be told that moving soon was a reason to skip solar. With a subscription it's closer to a reason to sign one, because there's nothing to pay off, nothing for a buyer to qualify for, and no filing sitting in the county land records. The flexibility is the product.
What does it cost, and what do you save?
Nothing up front, and the first bill arrives when the system switches on, not when you sign. Typical savings run around 40% of the current electric bill, so roughly $120 a month on a $300 bill. That's an estimate rather than a promise, and it moves with your roof, your shade and your usage. A small grid connection charge from the utility stays on your account either way. Ask what that one is. It doesn't go away, and quotes have a habit of forgetting it.
Two numbers to ask for before you compare anything to anything. What the subscription costs in month one, and what it costs in month 120, after the 1.9% annual increase has compounded. Any quote worth reading can produce both in a minute. Then test the savings claim, ours included, against what power really costs where you live (EIA Electric Power Monthly), and check the production assumption underneath it withthe federal PVWatts calculator. Both are free, and neither one is selling you anything.
The four ways to get panels, side by side
| Structure | Upfront | Lien on the home | Term | At sale |
|---|---|---|---|---|
| Cash | Full system cost | None | None | Easy, the panels are yours to sell with the house |
| Solar loan | $0 to some | Usually a UCC fixture filing | 10 to 25 years | Pay it off at closing, or the buyer takes on the loan |
| Lease or PPA | $0 | Often | 20 to 25 years | Buyer has to qualify and assume, or you buy the contract out |
| Subscription | $0 | None | 36 months inside a 10-year agreement | Walk after month 36, nothing for a buyer to assume |
The bottom row is why the comparison is usually short. Everything in the "at sale" column above it is a negotiation; the subscription row is a phone call. What the bottom row does not give you is ownership, and if ownership is what you're after, the top row is the honest recommendation. The structure-by-structure version of this is atsolar lease vs subscription.
What's the catch in the contract?
Two of them, and both live in the paper rather than the pitch. The commitment runs 36 months inside a written agreement of ten years, so there's no fee to cancel any time after month 36, and anybody selling you a three year contract flat is skipping pages. The second is the escalator. The price rises 1.9% a year, fixed. It's small, it's disclosed, and it exists.
Three years at 1.9% compounds to about 5.8% in total, which is a different animal from a 2.9% to 3.9% escalator running for twenty five years on a lease. That gap is most of the argument for this product, which is exactly why we name our own number before anyone asks. The long version is at solar escalator clauses. Whoever is selling to you, make them put a finger on the cancellation clause, including what the provider may choose to do if you leave inside the first three years. That part is discretionary, not promised.
What happens when you sell the house?
Nothing dramatic, which is the whole point. There's no lien to clear and no balance to pay off, so the closing doesn't wait on a finance company's paperwork. If the buyer wants the panels they can subscribe in their own name. Nobody is obligated to. If they don't want them, the provider takes the system off and repairs what it touched, at no charge to the seller.
Set that against the lease version, where a buyer has to qualify for a contract they didn't choose, and deals die in the inspection period over panels neither side wanted. The closing-table breakdown, structure by structure, is atselling a house with solar.
Get your number
No article can answer this for you, including this one. The number that settles it is your own bill against your own roof. Run your bill through the estimator and a real person follows up with figures for your address. If you want the mechanics first, start withhow the model works, or read the catch inwhat $0 down really means. And if the federal tax credit is the reason you're shopping at all, read what changed with the 30% credit before you assume it's still waiting for you.
