What do Tesla solar panels cost? Are they the best solar panel? (2023)

Tesla is often synonymous with high-end, luxury renewable technology, but its solar panel business can be a bit confusing. Tesla got into the solar industry in 2016 by acquiring SolarCity, with the goal of streamlining solar panel and battery storage manufacturing.

When Tesla took over, they retained the same sales and marketing infrastructure, but lacked the ability to produce solar panels at scale.

Tesla first partnered with Panasonic, in its Buffalo, New York gigafactory. Panasonic provided Tesla with solar cells, the component within solar panels that converts sunlight to electricity for energy generation.Unfortunately, Tesla and Panasonic’s solar cell production partnership ended in 2020 due to low demand from Tesla, although they remain in conjunction to build Tesla solar batteries for Tesla Powerwalls and electric vehicles.

Tesla then switched to using solar panels from third-party manufacturers, such as Korean solar giant Q CELLS, before introducing two lines of Tesla-branded solar panels for use in residential installation jobs.

Because of the mix of parties that can fall under the Tesla brand, clarity about what panels you receive when you purchase Tesla panels is a challenge. In this blog, we lay out what to expect.

    Does Tesla manufacture its own solar cells?

    No, Tesla is not the manufacturer of its solar cells.

    As noted above, until recently, Tesla had a partnership with international electronics giant Panasonic to create Tesla solar panels. The partnership was based around using the highly-regarded Panasonic HIT cells to create Tesla’s solar panels.

    After Panasonic’s departure from solar cell production for Tesla, we understand that Tesla no longer manufactures its solar panels. Instead, it appears to be using third-party manufacturers to source solar panels for installation jobs.

    The only exception is the Tesla Solar Roof, a solar shingle product, for which Tesla reportedly is making its own solar cells. However, the production and rollout of the Tesla Solar Roof has been hampered by cancellations and repeated delays.

    So what exactly are Tesla solar panels?

    The exact solar panels that Tesla uses on residential solar installations is constantly changing.

    With Panasonic out of the picture, Tesla first switched to using solar panels from Qcells. Then in April 2021, Tesla announced the launch of its own solar panel, the Tesla T420S.

    Since then, homeowners getting solar panels from Tesla have been offered either Tesla-branded solar panels or solar panels from Qcells. Further adding to the confusion, Tesla provides virtually no details about its solar panels on its website.

    So, what should you expect if you order Tesla solar panels?

    Well, right now it appears that for residential solar panel installations, Tesla is using two models of Tesla-branded solar panels, the H-series and the S-series. Both models appear to be Q CELLS panels with Tesla branding on them.

    Here are the key features of these solar panels.

    Tesla solar panel specifications
    ModelPower outputEfficiencyProduct warranty25-Year performance warranty
    Tesla T395H395 W20.1%25 years86%
    Tesla T400H400 W20.4%25 years86%

    Tesla T425S425 W19.6%25 years85%
    Tesla T430S430 W19.8%25 years85%

    Here’s a short summary of how Tesla solar panels compare to popular Tier 1 solar panel brands:


    Tesla uses large commercial-sized 72-cell panels, and each panel has an output of around 400 watts. However, when it comes to key technical specifications - such as module efficiency and temperature coefficient - Tesla’s solar panels are decidedly average compared to competing Tier 1 solar panel brands.

    For instance, the module efficiency of Tesla solar panels is 19.3%-20.6%, behind market leaders such as SunPower, which offers a solar panel with a max efficiency of 22.8%.


    Tesla offers three warranties. The solar panel product warranty is for 25 years, which is in line with the best solar panels on the market. The next is a 25-year performance warranty, where Tesla promises a maximum 0.54% annual degradation; this is slightly worse than average.

    Finally, there is the 10-year comprehensive warranty for the entire system, which includes the solar inverter, the (optional) Powerwall, and balance-of-system equipment. A 10-year warranty is pretty standard for inverters and solar batteries, but there is convenience to having all of these warranties from a single company.


    One of the biggest benefits of a Tesla solar panel system is its aesthetic appeal. Typical solar installations include skirting in an effort to hide all solar panel mounting hardware from the ground view, ensuring seamless integration into the roofing material.

    Tesla’s panels are also black in appearance, which ensures the panels are as aesthetically pleasing as possible.

    For more details, check out our full review of Tesla solar panels.

    Why are Tesla solar panels sourced from third parties?

    Tesla uses third-party panels for a few reasons.

    SolarCity’s business always sold third-party solar panels for its solar systems, and this practice carried over to their relationship with Tesla. Because it makes sense for Tesla to quote the cheapest cost solar panel to customers, it is not in its benefit to disclose the solar panel brand.

    With the former Panasonic partnership, those solar panels would technically be the “Tesla brand” solar panels. But, purchasing solar panels from other companies, like Qcells, was still practiced.

    Right now, it appears that Tesla is using Tesla-branded solar panels sourced from Qcells for most or all of its residential installation jobs.

    If you’re ordering a solar panel system, you should insist they provide you with the model and spec sheet of the solar panels they will be using. This will allow you to compare the solar panels against other leading solar panels in the market.

    How much do Tesla solar panels cost?

    Tesla solar panels range in price from $9,600 to $48,352, before incentives, depending on the system size that is best for your home.

    Tesla solar panel costs

    What is the right Tesla solar system size for your home?

    What do Tesla solar panels cost? Are they the best solar panel? (1)

    Tesla offers four standard solar panel system sizes. Image source: Tesla

    Until recently, Tesla offered a flat price for solar panel systems across the U.S. In March 2022, Tesla updated its solar pricing system, and there are now significant cost variations by state.

    In terms of cost per watt - a standard measure of comparing solar panel costs - Tesla solar panel systems can cost anywhere between $2.00 and $2.51 per watt.

    Luckily, estimating the potential cost for your home is pretty straightforward.

    You can go to the online portal and enter your address along with your average monthly electric bill to get a quote. In a trial run, we estimated the costs for a 2,300 square foot home with an average electricity cost of either $140/month, $280/month, or $420/month. Tesla recommended a 4.80 kW system, 9.60 kW system, and 14.40 kW system, respectively.

    The system sizes mentioned above are three of the standard system sizes that Tesla offers all residential solar customers. A fourth, larger system size - 19.20 kW - is offered in some markets, but you would need a very high electric bill to justify a system of that size.

    How much will a Tesla solar system cost for your home?

    It is actually pretty simple to figure out the cost of Tesla solar panels for your property based on your electricity usage.

    To determine the kilowatt hours (kWh) your home uses per day - and thus the system size you need - check your monthly electric bill. It will show you the number of kWh your home used that month. Divide that by the number of days in that month to get a daily usage figure.

    (Video) IT HAPPENED! For Only $0.22/w, Tesla 4.0 solar cell Can blow your mind!

    For example, if your home used 1,200 kWh in March, you would divide 1,200 by 31 to get an average of 38 kWh used a day. Based on solar system energy production estimates (shown in the table below), you’d probably need the 9.60 kW system.

    Final word on Tesla solar panels

    If you are a Tesla fan, Tesla solar panels are a great choice and can easily be installed with a Tesla Powerwall home battery for a completely renewable house.

    The solar panels might not be produced entirely by Tesla, but as long as you understand Tesla’s solar panel warranty, you should feel comfortable trusting a Tesla quote. Tesla does provide a 10-year workmanship warranty and at least 85% of nameplate power capacity after 25 years.

    But, Tesla solar panels are not the best option in the market in terms of panel efficiency. SolarReviews recommends these brands if you choose to shop for solar panels based on how efficient they are.

    Shop around and use our solar calculator to get a few competitive quotes before choosing a company and solar panel brand. After comparing costs, perhaps take advantage of Tesla’s price matching option if Tesla is your brand of choice.
