Whether you’re just starting your research or are ready to get a precise quote for your property, read on for expert insights on what to expect.
A Brief History of Tesla’s Solar Panel Business
Tesla made its initial foray into solar energy in 2016 when it acquired SolarCity, one of the largest residential PV installers in the country at the time. Tesla founder Elon Musk was also a co-founder and chairman of SolarCity, which was started by his cousins Lyndon and Peter Rive in 2006. The blockbuster $2.6 billion deal signified Musk’s broad vision for sustainable energy transportation and infrastructure under the Tesla brand.
Early efforts focused largely on integrating SolarCity’s existing sales and distribution network along with Tesla’s scalable battery pack technology. However, Tesla struggled with managing solar cell manufacturing, leading them to partner with Panasonic at their Buffalo Gigafactory 2 plant in 2017. Panasonic produced high-efficiency photovoltaic cells while Tesla packaged them into traditional solar panels and textured glass roof tiles.
But by early 2020, Tesla and Panasonic decided to end their solar cell partnership, with Panasonic pulling out of Buffalo plant operations completely eight months later. Tesla is now sourcing solar cells from alternative third-party suppliers like South Korea’s Hanwha Q Cells as they work to scale up and streamline their own in-house solar manufacturing line.
Today, Tesla offers two tiers of solar panels for residential installation – the standard S-series panels and high-efficiency H-series counterparts, detailed below:
Tesla Solar Panel Specs:
| Model | Power Output | Efficiency | Product Warranty | Performance Warranty |
|---|---|---|---|---|
| T395H | 395W | 20.1% | 25 years | 86% of rated power after 25 years |
| T400H | 400W | 20.4% | 25 years | 86% |
| T405H | 405W | 20.6% | 25 years | 86% |
| T420S | 420W | 19.3% | 25 years | 86% |
| T425S | 425W | 19.6% | 25 years | 86% |
| T430S | 430W | 19.8% | 25 years | 86% |
The H-series achieves higher efficiency thanks to 22.2% half-cut mono PERC solar cells, multi-busbar cell connections, and advanced low-stress lamination methods. But both H and S-series panels deliver over 19% efficiency and come with 25-year power and product guarantees – a testament to Tesla solar’s premium quality and performance.
Now let’s examine what all of this translates to when it comes to actual Tesla solar panel pricing for your home.
How Much Do Tesla Solar Panels Cost?
As you might expect for a luxury technology brand like Tesla, their photovoltaic solar panels sit at the higher end of price point spectrum in the wider residential solar installation market. Costs can also have significant regional variability depending on labor, permitting differences and state incentive programs.
However, on average most Tesla solar panel systems range from $2.65-$3.50 per Watt including installation charges. At the national median home price of 2,608 square feet, you would need a 7.5kW system with around 20 panels covering 400 square feet of usable roof space. This would cost roughly $19,875 – $26,250 before incentives based on Tesla’s pricing model as of mid-2022.
To get a more precise estimate matched to your specific home and location, Tesla offers an online solar calculator using satellite imagery of your roof, electricity bill history and current utility rates. After inputting your address and average monthly bill, their site will provide an automated recommendation for optimally sized solar array size along with estimated first-year savings and 25-year lifetime electricity offsets.
You can request an exact quote from a Tesla Energy sales advisor for free as the next step, who will evaluate your roof in closer detail and provide solar panel installment pricing tailored to your needs. Actual purchase prices may end up higher or lower than initial web calculator estimates depending on roof specifics, regional solar incentives and additional accessories like home battery Powerwall systems.
Let’s explore the additional cost factors that can alter your final pricing, both to your advantage and disadvantage.
Additional Equipment That Impacts Tesla Solar Panel Cost
Tesla’s online solar calculator provides system price estimates including their premium tempered glass solar panels, aluminum mounting hardware, cabling and a compatible inverter to convert DC to grid-ready AC power. But you may also want to invest in energy storage to unlock solar’s full potential:
⚡ Tesla Powerwall Battery
The crown jewel of Tesla’s energy ecosystem is their sleek rechargeable home battery solution designed specifically for solar energy storage. Powerwall allows your solar system to keep delivering clean electricity to your home around-the-clock, even when variable factors like weather disrupt generation.
The compact 528 lb, 51.5” x 34” x 7.5” module delivers 13.5 kWh of storage capacity – enough to run most homes during the evening and recharges each day from your panels. When combined with solar, Powerwall can provide indefinite backup power during grid outages to keep your essential appliances online.
Adding a single Powerwall unit to your initial Tesla solar purchase costs around $11,500 including supporting hardware and installation. Some local energy providers also offer incentives towards battery storage systems, discussed in the sections below. While not strictly required to benefit from solar panel installation, Tesla Powerwall maximizes your energy independence and cost savings over time.
Incentives Can Significantly Lower Final Costs
The main barriers for most homeowners interested in transitioning to solar power are high equipment, installation, and permitting costs across thousands of dollars. Thankfully federal, state/local governments, utilities companies and even some corporations offer solar incentives and rebates that let you recoup 30% or more of your initial investment in Tesla solar panels.
☀️ The Federal Solar Tax Credit
The most impactful incentive available is the federal Investment Tax Credit (ITC) that lets you deduct 30% of installed solar system costs directly from your income taxes. This includes nearly all expenses related to solar panel equipment, installation labor, permitting fees, site surveys and battery storage hardware.
You don’t need to pay any federal tax to qualify for the credit. If the ITC value exceeds your income tax, excess credit rolls over to subsequent years. There is no maximum limit either besides total system purchase amounts.
This means for a $20,000 Tesla solar panel installation, owning the panels outright would make you eligible for a $6,000 federal tax credit. Leased solar PV equipment also qualifies for tax savings incentives, but under a reduced ITC percentage and with equipment owner receiving majority credit benefit.
Starting 2023, the ITC will gradually phase down to a permanent 10% credit for commercial and residential systems. So purchasing your Tesla solar plus Powerwall system sooner than later means maximizing federal savings.
📉 State & Local solar incentives
Beyond the blanket federal ITC program, many state and municipal governments offer their own additional financial incentives for homeowners switching to renewable energy sources. DSIRE USA provides a comprehensive database of state, local, utility and federal incentives searchable by zip code and technology type.
Popular solar incentive programs include:
- Direct cash rebates that partially refund installation charges upfront. Often funded by carbon-linked cap-and-trade programs.
- Sales tax exemptions on solar equipment purchases that save you up to tens of thousands.
- Property tax exemptions that exclude PV system value addition from increased home valuation assessments. Prevents property tax hike.
- Renewable Energy Credits (RECs) that you can sell per generated MWh as tradeable carbon offset instruments.
- Net metering bill credits when fed-back excess solar electricity exceeds personal usage needs. Payoff occurs at annual true-up.
- Low-interest solar loans through state green banks / credit unions that beat conventional financing rates.
In solar-friendly states like California, combining local, state and utility solar incentives can shave $10,000 or more extra off your final Tesla solar panel system costs after federal ITC. Run a personalized DSIRE incentives report using your zip code to uncover every available option.
💸 Other Tesla Solar Incentive Opportunities
Some employers, military branches and even brands like Tesla themselves also offer eco-conscious incentives if you install solar panels or sustainable products at home.
For example, as a solar industry leader, Tesla provides their own employees with a $500 bonus for going solar at their personal residence. Elon Musk’s environmental dedication permeates corporate culture from top to bottom.
Veterans, active-duty service members and military families also qualify for 10-15% instant discounts on Tesla solar panel and Powerwall products installed at their homes.
Research all avenues to maximize incentives beyond conventional residential solar programs – you never know what environmental or ethical initiatives could score you bonus savings!
Financing Options For Tesla Solar Panels
Even after factoring available solar incentives, the sheer upfront expenditure of equipping your home with customized Tesla panels + battery storage is daunting for average homeowners.
Thankfully you don’t have to pay your entire 15-25 year solar system investment back in one huge lump sum – various flexible financing options can ease the initial purchase pain and spread repayments over months or years. Let’s examine popular avenues to fund your Tesla solar transformation:
⚡ Tesla Solar Loan
For convenient in-house financing, Tesla offers its own solar & battery loan program with straightforward terms for qualified residential applicants covering full system costs.
Tesla Solar Loan highlights:
- Fixed annual percentage rates (APR) as low as 2.49% – 7.49% based on creditworthiness
- No early repayment fees or penalties
- 15-year max loan tenure for 100% purchase amounts
- Quick conditional pre-approval decisions within seconds
- Start payments only after your solar installation activates
Loans applications are currently available online for homeowners in AZ, CA, CT, FL, HI, IL, MA, MD, NH, NJ, NM, NV, NY, OR PA, RI, TX, UT, VA, VT & WA states.
If shopping as a cash buyer instead, Tesla guarantees your final solar price with a 60-day installation deadline once 10% payment is made.
💵 Cash Purchases
Paying the full cost of your customized Tesla solar + Powerwall system outright in a lump sum means no loan interest charges or financing fees chipping away at long term savings. You’ll also maximize federal tax credit and incentives values for year-one returns.
However, fronting $15,000 – $35,000+ in one go requires sufficient cash savings set aside or arranging your own third-party financing. Home equity loans often offer the lowest rates thanks to secured collateral – just ensure repayment terms match expected solar payback period.
🏡 PPA Agreements
If low upfront costs are most essential, Power Purchase Agreements let homeowners lease their solar systems from a third-party investor or solar company who claims equipment tax incentives and rebates in exchange.
You pay a fixed kilowatt-hour rate for “solar electricity service” based on actual generation with no system ownership. Rates increase at a fixed percentage yearly often lower than regular utility. Functions similar to a solar loan but often zero down payment.
Ending PPA contract or selling house requires either negotiating fair buyout deal or transferring agreement to subsequent homeowners. Look out for prepayment penalties while trying to settle buyouts as well.
Tesla Solar Panels vs Complete Solar Roofs
As a final pricing comparison, should you consider taking the solar leap with Tesla’s high-efficiency panels mounted conventionally on your existing roof or their integrated tempered glass solar shingle roofs that completely transform your home’s exterior finish?
While more visually striking, Tesla Solar Roof systems are notably more expensive starting from $33-$42 per square foot depending on roof tile mix required. Installation is also substantially more complex. You can request a custom Solar Roof quote from Tesla as well.
For the median 2,608 square foot American home at $100 per square foot, total Solar Roof costs range from $75k on the very low-end to $130k+ for larger premium houses. Even with solar incentives and rebates, that likely surpasses most homeowners’ budgets.
By comparison, adding a 20-panel 7.5 kW Tesla solar system runs around $20,000 as outlined previously. Unless you specifically want an integrated photovoltaic glass roof aesthetic for design appeal or storm resilience, traditionally mounting premium panels from their H-series line likely makes better economic sense for most.
You still retain the option of combining high-efficiency Tesla PV modules with their sleek Powerwall batteries for sustainable electricity plus energy storage. Overall value is hard to beat!
