Tesla solar reviews are mixed in a predictable way: owners and reviewers like the price, the app and the Powerwall pairing, while the most common complaints involve slow customer service and installation timelines. Tesla panels are mainstream hardware, and Tesla's quoted price per watt has generally run below the national average. This guide summarizes what owners and independent reviewers report, with the points to verify before you sign.

What Tesla solar owners and reviewers say
Independent reviews line up on a few themes. EnergySage rates the panels as middle-of-the-pack on specifications and notes a reputation for customer service and installation-timeline problems, while saying production delays have eased. This Old House describes service in some reviews as "slow and inefficient," with others saying it has become easier to reach. Both note that experiences vary by location.
What owners tend to like:
- Upfront online pricing. You can get a quote without a sales visit.
- Lower quoted price per watt. See the table below.
- One ecosystem. Panels, inverter, Powerwall 3 battery, EV charger and app all come from one company.
- Price match. Tesla advertises matching comparable competing quotes; ask for the current terms in writing.
What owners and reviewers report as problems:
- Customer service and communication. Delays, hard-to-reach staff and slow responses.
- Installation and permission-to-operate timing. One owner told a reviewer that a delay caused them to miss that year's federal credit, though Tesla refunded the difference.
- Shorter workmanship warranty. 10 years, versus 25 from some installers.
Tesla solar panel reviews: specs, price and warranty
| Item | Reported figure | Source |
|---|---|---|
| Panel models | TSP-415 and TSP-420 (415 W and 420 W), about 20.3% to 20.5% efficiency | EnergySage |
| Product and power warranty | 25 years each; 98% output in year 1, at least 87.2% at year 25 (EnergySage) or 85% (This Old House) | EnergySage, This Old House |
| Workmanship warranty | 10 years | This Old House |
| Average price from marketplace quotes | $2.81 per watt | EnergySage |
| Price from Tesla's online quote tool | $2.30 to $3.10 per watt | This Old House |
| National average used for comparison | $3.33 per watt | This Old House, citing SEIA |
| Powerwall 3 | 13.5 kWh; 10-year warranty, at least 70% capacity retained after 10 years | This Old House |
Treat these as typical ranges. Your price depends on system size, roof complexity, battery choice, local permitting and, since the federal homeowner credit ended, how the system is financed. Our cost per watt guide shows how to compare quotes on an equal basis.
How Tesla sells solar: cash, loan or lease
Tesla offers cash purchase and loans, and its support site describes a lease in its direct service territories. The Tesla lease terms listed there are a 25-year term for solar (with or without Powerwall), $600 upfront, payments starting at permission to operate, and a 3% annual payment increase. Tesla lists a 95% availability guarantee measured every two years, with compensation if it is missed. Buyout is available after year five at the price in your contract, and the lease can be transferred if you sell. Availability depends on where you live, so confirm what you are actually being offered.
Because the federal 25D credit ended for systems finished after 2025, a purchase no longer carries a 30% federal credit. A lease places that decision with the owner. Read our comparison of loan, lease and PPA before you choose.
Tesla Solar Roof and company news
Tesla Solar Roof is a separate, far more expensive product, and Aurora Solar reported in August 2026 that it had been discontinued, with no formal public announcement; existing installations remain under warranty. Tesla launched a conventional all-black rooftop panel in January 2026, per the same report. If a salesperson offers a roof product, confirm it is still sold and who services it.
Reported complaints and regulatory issues
Local TV station KEYT reported in November 2023 on a California homeowner who said a Tesla system was never connected and that Tesla did not resolve it; the station also reported that California had taken disciplinary action against Tesla Energy and that Tesla was appealing. Tesla did not respond to the station's requests. This Old House reported a Better Business Bureau rating of F as of February 2025. These are reports about specific cases and a rating snapshot, not a verdict on every install. Check the current BBB profile and your state contractor board for the entity that will do your work.
What to verify before signing with Tesla
- Who is the installing entity, and is it licensed in your state? Verify on your state licensing board.
- Written timeline from contract to permission to operate, and what happens if it slips.
- Exact panel, inverter and battery models in the contract.
- For a lease: the escalator, the year-25 payment, buyout rules and transfer process.
- Roof warranty coverage and who pays if the roof needs work later.

Frequently asked questions
Are Tesla solar panels any good?
Tesla's panels are conventional monocrystalline modules of about 415 to 420 W with a 25-year product and power warranty. EnergySage scores them as middle-of-the-pack on specs. Most criticism concerns service and timelines rather than the hardware, so compare the full package against local quotes.
How much do Tesla solar panels cost per watt?
EnergySage reports an average of $2.81 per watt from marketplace quotes, and This Old House reports $2.30 to $3.10 per watt from Tesla's online quote tool, against a national average of $3.33. Your price depends on system size, roof and battery choices.
Does Tesla offer a solar lease?
Tesla's support site describes a 25-year solar lease in its direct service territories, with $600 upfront, a 3% annual payment increase, a 95% availability guarantee and buyout after year five. Availability depends on your location, so ask for the contract before comparing.
Is Tesla Solar Roof still available?
Aurora Solar reported in August 2026 that Tesla Solar Roof had quietly disappeared from Tesla's website, with no formal public announcement, and that existing installations remain under warranty. Ask Tesla directly before relying on any roof-product quote.
What should I check in a Tesla solar quote?
Confirm the licensed installing entity, equipment models, timeline to permission to operate, warranty split between product and workmanship, and for leases the escalator and buyout terms. Then compare the price per watt with at least two other bids.
