As one of the leading manufacturers of electric vehicles and energy storage systems, Tesla has become a recognized name in renewable energy. Besides developing eco-friendly cars, Tesla also sells solar panels and solar roof tiles to residential homeowners looking to go green.
But how much exactly do Tesla‘s solar offerings cost? With factors like incentives, warranties and financing options affecting the final price, it can get confusing for the average homeowner.
This comprehensive 2,500+ word guide on Tesla solar panel costs breaks down all the pricing details to help you make an informed decision.
A Brief History of Tesla‘s Solar Business
Tesla entered the solar energy space in 2016 when it acquired SolarCity, one of the largest solar panel installers in the U.S. at the time. The goal was to provide integrated clean energy products, combining SolarCity‘s established sales network with Tesla‘s battery technology and manufacturing capabilities.
To ramp up solar cell production and lower costs, Tesla initially partnered with expert manufacturer Panasonic. But this partnership ended in 2020 due to flagging demand, prompting Tesla to source solar cells from alternative suppliers:
- Q CELLS: A Korean solar brand and one of the largest module manufacturers globally
- Heliene: A Canadian solar company offering high-efficiency panels comparable to the Panasonic cells
- Unnamed third-party suppliers mostly based in Asia
Currently, Tesla sells two lines of solar panels for residential installations:
S-Series: Mainstream solar panels with power outputs ranging from 420W to 430W
H-Series: High-efficiency panels ranging from 395W to 405W
All Tesla solar panels come with a 25-year warranty that guarantees at least 86% of original performance after 25 years. Let‘s look at estimated system costs next.

What Influences Tesla‘s Solar Panel Pricing?
While Tesla‘s solar calculator provides ballpark figures, your final price depends on several additional factors explained below:
Battery Storage Costs
Tesla‘s Powerwall battery enables solar panel systems to store energy for usage at night. Adding a Powerwall will cost $11,500 extra.
Incentives and Rebates
A 30% federal tax credit and additional state/utility incentives can lower out-of-pocket solar panel costs significantly.
Property Taxes
Most states exclude the value added by solar installations when calculating property taxes. This provides savings over the system‘s lifespan.
Electricity Bill Savings
Solar energy systems offset expensive grid electricity usage, helping recoup the hardware investment over time through utility bill savings.
Financing Options for Tesla Solar Panels
While cash purchases may be most economical, Tesla provides the following financing options to help pay for solar over time:
Tesla Solar Loan
Financing for the entire cost of Tesla solar panel hardware/installation at competitive interest rates.
Solar Leases/PPAs
Make monthly lease payments to a solar provider who installs and owns the system on your property.
Home Equity Loan
Leverage your home equity to finance solar panels through a collateralized loan product.
Tesla Solar Roofs: The Premium Rooftop Solar Option
For homeowners wanting complete reroofs with integrated solar generation, Tesla offers premium solar roof shingles with a sleek aesthetic. As per Tesla, average solar roof costs are $21.85 per square foot.

| Large | 45 | 11.4 kW | $118,000 |
*Includes installation costs but not federal tax credits
20-Year Cashflow Analysis
The upfront cost of installing a solar energy system may seem high, but tax incentives bring down the net purchase price. More importantly, electricity bill savings from solar energy offsets grid power costs over the system‘s 20+ year lifespan.
Here‘s a projection of the 20-year cashflows from installing a 10 kW Tesla solar system with one Powerwall battery:
Assumptions
- System Price: $30,000 (after tax credit)
- Financing: None/Paid Upfront
- Electricity Rate: $0.20/kWh
- Annual Utility Inflation: 2%
Within about 6 years, the cumulative savings from lower electricity bills exceed the upfront solar panel cost. Savings continue building over 20+ years from essentially free power generation.
Let‘s analyze additional scenarios for low, average and high electricity rates next.
Cost Savings Projections Across Electricity Rate Scenarios
Your actual savings from installing Tesla solar panels heavily depends on your local electricity rate and future utility inflation.
Places with already high electricity costs stand to benefit even more. See cost savings projections across three rate scenarios below:
5 Year Projection
| Electricity Rate | 5-Year Savings |
|---|---|
| $0.15 per kWh | $5,200 |
| $0.20 per kWh | $8,900 |
| $0.30 per kWh | $16,300 |
20 Year Projection
| Electricity Rate | 20-Year Savings |
|---|---|
| $0.15 per kWh | $43,100 |
| $0.20 per kWh | $86,500 |
| $0.30 per kWh | $183,700 |
Based on the projections, more expensive grid electricity translates to bigger long-term savings from switching to solar power.
Of course, electricity rates don‘t rise linearly year to year. But broadly, panels installed when rates are higher to start with realize greater savings over their lifespan.
Federal Solar Incentives and Trends
The Investment Tax Credit (ITC) remains one of the most lucrative financial incentives to install solar panels in the U.S.
This federal program offers a tax credit equal to 30% of the total system cost, including installation labor and hardware expenses. Based on legislation passed in 2020, the commercial and residential ITC percentage will gradually phase down over time per the schedule below:
| Year | Residential ITC % | Commercial ITC % |
|---|---|---|
| 2022+ | 30% | 30% |
| 2024+ | 26% | 26% |
| 2026+ | 22% | 22% |
| 2028+ | 0% | 10% |
So homeowners building solar systems in 2023 or 2024 can still capitalize on a 30% and 26% credit respectively before the incentive starts stepping down further.
The phaseout schedule gives homeowners a few years to get quotes and plan financially for panel installations. Acting ahead of the scale back by starting the process now makes most economic sense.
State governments and utilities also offer additional incentives like rebates to improve solar panel affordability.
Key State-Level Solar Incentives
While federal tax credits provide the biggest boost, state and local solar incentives can provide thousands in additional savings.
Here are some top state-level incentives homeowners can leverage across the U.S.:
California
- Up to $9,000 back through state solar rebates under the California Solar Initiative program
- Time-of-use electricity rates reward solar customers for generating surplus energy back into the grid
New York
- 25% back in tax credits under NY-Sun incentives
- Up to $5,000 additional rebate from utilities like National Grid
Florida
- No sales tax on solar panel installation equipment
- Property tax exemptions on the added value from solar systems
Massachusetts
- Income tax credits and property tax exemptions
- Solar loans through Mass Solar Loan program
The Database of State Incentives for Renewables & Efficiency offers a full breakdown of current solar rebates and exemptions by state.
Impact of Solar Incentives on System Payback Periods
The incentives above, especially the federal ITC, can dramatically accelerate ROI timelines for Tesla solar installations.
Assuming average electricity rates, here‘s how the payback period changes under two incentive scenarios:
| Incentive Scenario | Payback Period |
|---|---|
| No Tax Credits | 11 years |
| With 30% ITC | 5-6 years |
The significant savings from tapping into federal and state solar incentives make Tesla systems cashflow positive even faster.
Emerging Solar Financing Structures
For homeowners wanting to go solar with minimal upfront costs, third-party financing models like solar leases and PPAs help eliminate panels as a major capital expense.
Under these agreements, an external company handles system ownership, installation and maintenance for your property. The homeowner simply pays a fixed monthly lease rate to essentially "rent" the solar panels on their rooftop.
Typical terms are 20 years over which the solar leasing provider recoups their hardware investment through your lease payments. But you as the property owner get to enjoy lower grid energy bills immediately!
Pros
- Little to no upfront solar costs
- Immediate savings on energy bills
- System maintenance/performance worries handled by leasing firm
Cons
- Monthly payments ultimately cost more than owning over 20 years
- Locked into lease contract with escalators
- No access to tax credits
If going solar for minimal investment is prioritized over maximizing lifetime savings, solar lease/PPA models remain an option to consider.
Just be sure to run the numbers and compare total 20+ year costs against direct purchase scenarios accounting for incentives.
The Solar Purchase Process
Now that we‘ve explored Tesla solar pricing models and incentives in detail, let‘s walk through the buying process from start to finish.
Step 1: Request quotes from Tesla and multiple local installers
- Have companies provide customized quotes catered to your roof and energy profile
- Compare pricing across vendors
Step 2: Vet installers carefully before selecting your preferred vendor
- How long have they been in business?
- Can they provide referrals or case studies from past residential projects?
- What permit/inspection process do they follow? How will they handle project logistics?
Step 3: Choose financing
- Decide whether to buy outright or pursue solar loans/leases after comparing total 20-30 year costs
Step 4: Installation & Activation
- Full installs generally take 1-2 days with another few days for inspection
- System activation occurs after securing clearance certificates from the local utility
The best way to maximize savings over 20+ years is buying solar outright if possible to capitalize on federal tax credits and available state rebates. Tesla provides competitive hardware pricing, but quotes from multiple installers is recommended.
Make sure you understand the full purchase and installation process before committing to an installer.
Additional Equipment Needed With Solar Panel Installations
Beyond the solar modules themselves, full solar energy systems require other critical components:
- Racking: Rails that physically attach and anchor solar panels to rooftops. Aluminum and galvanized steel are common durable materials.
- Wiring: Transmits generated DC electricity from panels to the inverter equipment. Outdoor-safe cabling is mandatory.
- Conduit: Enclosed tubing to protect wiring between array and electronics.
- Combiner box: Aggregates output from multiple panels into one input for the inverter.
- Inverters: Converts raw solar DC output to usable AC power for home grid integration and usage.
- Batteries (optional): Stores excess solar energy for nighttime usage as backup resilience.
Tesla‘s website provides detailed guides on system components they use for their installations. Reputable solar installers generally use high-grade electrical infrastructure.
When evaluating installer quotes, be sure to validate that factors like permitting, inspection, monitoring hardware and electrical safety gear are included. Avoid providers cutting corners on vital wiring and racking equipment.
