Are Tesla Solar Panels Worth It? Cost, Lease and Payback

At Tesla’s average per-watt prices, an 8-kilowatt (kW) solar system works out to between about $20,300 and $27,600 in the eight states where Tesla published averages from its internal data, on a page it last updated October 3, 2025. Until the end of 2025, a 30% federal tax credit would have taken roughly $6,100 to $8,300 off that bill. The Internal Revenue Service (IRS) says the credit “is not available for any property placed in service after December 31, 2025,” so a system you buy in 2026 gets no federal credit. Whether the panels pay you back now depends heavily on what your utility charges per kilowatt-hour (kWh), and on what it pays for power you send back.

The short answer: in Connecticut, Massachusetts and New York, where electricity is expensive, this site’s math puts a cash purchase at about 8 to 9 years to break even (about 7 in New York with its state tax credit). In lower-rate Arizona, Florida and Texas, it’s about 9.5 to 12 years. Hawaii and California look faster on paper (4.4 and 5.4 years), but those two figures count every kWh at the full retail rate, and new solar customers at California’s big three utilities usually get less than that for power they export, as do new customers of Hawaiian Electric, which serves Honolulu. Leasing cuts the upfront cost to about $600, but Tesla itself says ownership “delivers greater lifetime financial benefit.” And the Solar Roof is gone: Electrek reported on August 20, 2026 that Tesla stopped supplying the tiles.

Is Tesla solar worth it? Payback by state

This table is this site’s own calculation. It takes the average price per watt in eight states from a Tesla cost page last updated October 3, 2025, prices an 8 kW system with it, and divides by what that system’s modeled yearly output would be worth at the state’s average 2025 residential electricity rate. The output figures come from PVWatts, a solar production calculator from the Energy Department’s National Laboratory of the Rockies (NLR), for a south-facing roof in one city per state.

*Doesn’t hold for new customers of California’s three big utilities or of Hawaiian Electric: their exports usually earn less than the retail rate used here, so payback runs longer than shown (details below).

How the table was built: system cost = 8,000 watts × Tesla’s price per watt. Output worth = PVWatts’ modeled first-year output (alternating current, from an 8 kW panel rating, using typical-year weather data) × the state’s 2025 average residential price from the U.S. Energy Information Administration (EIA). Payback = cost ÷ output worth. The PVWatts runs modeled a fixed roof mount with a 20-degree tilt, facing due south, with 14.08% system losses. It’s simple payback: no panel wear over time, no change in electricity rates, no loan interest, no repair or inverter costs, and every kWh valued at the retail rate.

What moves your real number:

• How your utility credits power you send back. In the territories of California’s three big investor-owned utilities, Pacific Gas and Electric (PG&E), Southern California Edison (SCE) and San Diego Gas & Electric (SDG&E), customers applying for interconnection since April 15, 2023 take service on a net billing tariff, and the older net energy metering tariffs are closed to new enrollments. The state’s utility regulator says export credits under net billing are “usually lower than the retail rate,” though they “can rise above the retail rate on late summer evenings.” Solar power is first used to serve your own home, and net billing customers must take a specific time-of-use rate. Those rules cover the territories of those three utilities; if a different utility serves you, check its own export rules. On Oahu, Hawaiian Electric’s current export program pays 13.5¢ per kWh for power sent to the grid from 9 a.m. to 5 p.m., 32.9¢ in the 5 p.m. to 9 p.m. evening peak and 18.9¢ overnight (its 2024 to 2026 rates), against the 40.40¢ statewide average residential price in the table. Its other islands pay less than that average too: Maui 13.1¢, 6.6¢ and 18.2¢, Hawaii Island 14.8¢, 10.6¢ and 23.1¢, and Molokai 17.4¢ to 27.2¢. Lanai is the one exception, at 40.8¢ in the evening peak. Hawaiian Electric says its export rates “will be updated every 3 years” and are “locked in for the first 7 years of any new interconnection agreement,” so a system hooked up in 2027 may get different rates. Your own utility’s residential rate can also differ from the statewide average used in the table. The more of your output you export at rates like those, the longer your payback. Ask your installer or utility how exports are credited before you sign.
• State incentives. Tesla’s cost page points to New York’s state tax credit of 25%, up to $5,000. On the New York row, that cap applies, and it cuts the payback from 8.8 years to about 6.9.
• Your own quote. The per-watt figures are a sample of averages “for 8kW solar systems or larger, based on Tesla Energy’s internal data,” on a page Tesla last updated October 3, 2025 (the table itself carries no date), and the eight states are a pricing sample, not a map of where Tesla installs. To buy, Tesla says that when you place an order “you can see your estimated purchase price based on your selected system details.” To lease, you enter your address and average electric bill for an estimated monthly price, and the contract you get after the design stage spells out your pricing.

For scale, Tesla’s own cost page says the payback period for a solar system “typically” spans 6 to 12 years, citing a Department of Energy planning guide.

How much do Tesla solar panels cost?

Tesla’s cost page quotes the Department of Energy’s all-in range of $2.74 to $3.30 per watt and says that puts an average 8 kW home system at “between $21,900 – $26,400.” Its own averages for the eight states in its sample, on a page last updated October 3, 2025, run from $2.54 a watt in Arizona to $3.45 in Massachusetts.

Where the money goes, per the Department of Energy figures Tesla cites: materials are typically 43% of the cost, installation labor about 7%, and design, engineering, project management, approvals and other overhead 28%. Tesla also says its permitting fees to building and electrical departments ran about $110 to $760 per installation in 2024.

What you get: Tesla’s current panel is rated at 420 watts, measures 71.1 by 44.7 inches, and is “assembled in Buffalo, New York.” Tesla says it has “three times more power zones than traditional solar panels” to make more power under shade. For a purchased system, Tesla’s warranty page says the panels are guaranteed by their maker to at least 80% of nameplate power for at least 25 years, and Tesla’s payment page lists a 10-year comprehensive warranty alongside it.

Who installs it matters. Tesla’s solar page says “Tesla or a solar panel installer will work with you,” and that Tesla or a Tesla Certified Installer designs the system. That affects two things below: the lease is offered only in Tesla’s direct service territories, and the referral discount counts energy products only if Tesla installs them. Confirm that Tesla itself is your installer before you count on either.

What happened to the federal solar tax credit?

For a system you own, it’s over. The Residential Clean Energy Credit was worth 30% of the cost, and the IRS says it isn’t available for property placed in service after December 31, 2025. It was also nonrefundable, so it only offset tax owed, though unused amounts could carry forward to later years. The same IRS page still carries older wording about the credit beginning to “phase out in 2033,” but its controlling line is the December 31, 2025 cutoff.

One thing to watch: Tesla’s payment-options page still shows the Investment Tax Credit as “Yes” for cash and loan buyers. For a homeowner, that’s the credit the IRS says has ended, so don’t count on it in your math. Tesla’s cost page itself says federal tax incentive amounts “may continue to change” and tells you to check the IRS website.

A leased system is different, because Tesla owns it. Tesla’s lease page says that, as the owner, it “earns eligible incentives and applies them to reduce your monthly lease payment.” EnergySage, writing about the One Big Beautiful Bill Act signed July 4, 2025, says the companies behind leases and power purchase agreements (PPAs) can still claim a 30% commercial credit under the tax code’s Section 48E. That credit has a deadline. The tax code now says it “shall not apply” to solar property placed in service after December 31, 2027. The 2025 law’s effective-date note (Public Law 119-21) applies that cutoff to facilities whose construction begins more than 12 months after July 4, 2025. Construction is the leasing company’s milestone, not your signing date. So unless construction on your system began by July 4, 2026 (ask Tesla), a leased system generally needs to be in service by December 31, 2027 for that credit to apply. Ask Tesla whether your quoted payment assumes it and what happens if installation slips.

Is a Tesla solar lease worth it?

It depends on what you’re comparing it with. Tesla’s lease page says leasing gives “the lowest upfront and monthly costs” and that ownership “delivers greater lifetime financial benefit.” EnergySage makes both cases. Because the homeowner credit ended while the commercial credit survives, it says “leasing solar panels may now be more affordable than buying them yourself.” It also says a lease “almost always provides much less long-term savings than owning a system outright that is purchased with cash or a loan.”

Here are the terms Tesla lists for a solar lease:

On paying it off early, Tesla’s FAQ says: “No. Not at this time but you can exercise buyout options beginning after year five.” Its section on selling your home, though, lists “Pay off the lease early before the sale” as an option, next to transferring the lease to the buyer. Ask which applies before you sign.

Tesla doesn’t publish lease prices. You see an estimated monthly price after you enter your address and average electric bill. What you can work out ahead of time is the escalator. This site’s calculation from Tesla’s 3% yearly increase: the payment in year 25 is about double the year-one payment, so a $100 monthly payment becomes about $203, and over the full term you pay about 36.5 times your first year’s total. Compare that with how fast your utility rates have been rising before you assume the lease stays cheaper than the grid.

A lease makes the most sense if you can’t or don’t want to pay cash or take a loan, or you want Tesla handling repairs for 25 years. If your credit is excellent, Tesla’s own loan starts at $0 down, and you own the system.

Does Tesla solar offer financing?

Yes. Tesla lists three ways to pay: Tesla Financing, a lease, or cash.

†The same page says “All contracts require a $1,000 progress payment towards your total system cost at the time you finalize your system design.” That doesn’t square with the $600 lease upfront (a $100 deposit plus a $500 progress payment) on Tesla’s lease page, so confirm the amounts in your contract.

With financing, the first payment is due 35 calendar days after the system gets permission to operate, and you can change your payment type until installation begins. Tesla doesn’t list its loan rates on that page, so compare its quote with a credit union or home-equity rate. A loan’s interest adds to the payback years in the table above, which assume cash.

Is the Tesla Solar Roof discontinued?

Electrek reports yes, and Tesla’s site no longer offers it. Electrek reported on August 20, 2026 that Tesla told its certified third-party installers that solar roof tiles “are no longer available to order,” citing two sources close to the program, one of whom said Tesla had concluded the product wasn’t financially viable. On October 31, 2026, tesla.com/solarroof redirected to Tesla’s solar panel page, which offers no Solar Roof. Tesla’s cost page, last updated October 3, 2025, still mentions “our solar roof and solar panels.” Wood Mackenzie estimated, per Electrek, that Tesla installed only about 3,000 Solar Roof systems in the US across roughly seven years.

If you need a new roof and wanted solar built in, your Tesla options are now a conventional roof plus panels. Tesla’s panels use its Panel Mount hardware, with skirts that keep them close to the roof and “no visible fasteners.”

Can Tesla solar panels power a whole house?

Over a year, often yes. In the eight cities modeled above, an 8 kW system would make about 10,000 to 14,000 kWh a year. The EIA says the average US residential customer bought 10,791 kWh of electricity in 2022. So an 8 kW system roughly matches an average home’s yearly use in the cloudier Northeast cities and makes about 30% more in Phoenix. Tesla says the more energy you use, the more panels you need, and lists large homes and air-conditioned homes as ones with higher needs.

Hour by hour is different. Panels make power when the sun is out. Tesla’s pitch for nights and outages is the Powerwall: pair one with the panels to “store your excess energy for use whenever you want,” and Tesla says the battery “can keep your lights on when outages occur.” That adds a lot of money. What a Powerwall costs and which utilities help pay for one is in Is a Tesla Powerwall worth it?.

Buying with a referral link

As of October 31, 2026, Tesla’s referral page showed $400 off for “Solar Panels & Powerwall.” The Refer and Earn rules are narrower. They list solar panels as the only product that earns a buyer benefit, so a Powerwall on its own isn’t on the buyer list. You qualify only if you have never owned a qualifying Tesla product and you use the link before you order, and energy products count only if Tesla installs them. Tesla’s page names the Model 3, Model Y, Cybertruck and solar panels as qualifying products for loyalty benefits. It describes those as available if you “currently own” a qualifying product and buy another using the same Tesla Account, while a note further down says “currently or have previously owned.” Ask which applies to you.

If you qualify, this site’s Tesla energy referral link shows the current offer. (Full disclosure: Trendy Tech Tribe earns a referral reward if you buy Tesla-installed solar panels through it.) Already drive a Tesla? The Tesla referral guide covers what a link can do for you now, and the Tesla tax credit guide covers which car credits ended. If your winter bills are what’s pushing you toward solar, why your electric bill is high in winter breaks down where that money goes.

Tesla solar questions

How much does a Tesla solar system cost?

At the average prices on a Tesla cost page last updated October 3, 2025, $2.54 to $3.45 per watt for systems of 8 kW or larger in its eight-state sample, an 8 kW system works out to about $20,300 to $27,600. Your estimated purchase price shows up when you place an order with your system details.

Is there still a federal tax credit for solar panels?

Not for a system you own. The IRS says the 30% Residential Clean Energy Credit isn’t available for property placed in service after December 31, 2025. On a lease, Tesla owns the system and says it applies the incentives it earns to lower your payment.

How long do Tesla solar panels take to pay for themselves?

On this site’s simple math with Tesla’s average prices (from a cost page last updated October 3, 2025) and 2025 electricity rates, about 8 to 9 years in Connecticut, Massachusetts and New York, and 9.5 to 12 years in Arizona, Florida and Texas, for a cash purchase with every kWh valued at the retail rate. Where exports are credited below retail, as for new customers under California’s net billing tariff or Hawaiian Electric’s export program, it takes longer.

How long is a Tesla solar lease?

25 years for solar or solar plus Powerwall, with payments rising 3% a year, $600 upfront, and a buyout option after year five.

Can you still buy a Tesla Solar Roof?

No. Electrek reported on August 20, 2026 that Tesla told its certified installers the tiles are no longer available to order, and tesla.com/solarroof now leads to the solar panel page.
