Pros and Cons of Tesla Solar Panels

✔ Allows customers to receive an instant online quote
✔ Offers a solar panel price-match guarantee
✔ Provides 24/7 solar panel monitoring through their mobile app

✘ Customer service can have lengthy long wait times for repairs
✘ Powerwall battery systems are not available for purchase separately

Tesla Solar Panel Design Options

Tesla designed its minimalistic solar panels with no visible grid, a concealed edge, and a low profile, so your system doesn’t attract unwanted attention after installation. The panels interlock when installed, forming one solid solar panel array. Along with their modern aesthetic, the panels withstand temperatures of up to 185 degrees Fahrenheit.

Tesla offers standardized solar system sizes: small (12 panels), medium (24 panels), large (36 panels), and extra-large (48 panels). This makes the process of purchasing a system more simple and straightforward.

  • Wattage: 425 watts
  • Weight: 47.4 pounds
  • Dimensions: 82.4” x 40.9” x 1.57” (including frame)
  • Frame type: Black anodized aluminum

Other Solar Products Offered by Tesla

Tesla offers energy storage and an alternative solar power generator with its battery backup and solar roof offerings.

  • Powerwall—Tesla allows customers to store the excess energy their solar panels generate with a home battery backup. The Powerwall battery collects energy for you to use at night or provide backup power during an outage.
  • Solar roof—The Tesla solar roof is an alternative to solar panels and replaces your current roof with solar shingles. The solar shingles act as mini solar panels, harnessing sunlight to produce electricity for your home. This is an option to consider if you’re already considering installing a new roof.

Tesla Solar Warranty Options

All Tesla solar panels come with a 25-year performance guarantee which states performance is guaranteed by the manufacturer to at least 80% of nameplate power capacity for at least 25 years. This is somewhat vague language when compared to other solar installation companies’ warranties that state your guarantee is good for 25 years with no power capacity conditions applied to it.

Tesla also includes a 10-year comprehensive warranty. This warranty applies to all components of the solar system, and it helps with issues involving the Powerwall, inverters, and any roof-mounting problems and roof leaks.

Tesla Solar Reviews

Tesla, Inc. currently features a A+ rating on the Better Business Bureau (BBB), and it is not accredited. It should be noted that some companies decide not to obtain accreditation from the BBB because it comes at a cost.

Critical customer reviews on the site mention difficulty in scheduling maintenance or installation of Tesla solar products. Other reviews mention how friendly and helpful Tesla’s customer service representatives are and the amount of savings.

Read over some of the comments Tesla Solar customers have about their experiences here:

“The whole procedure was smooth and easy for me. Neal was an excellent advisor, clear, concise and knowledgeable. The installation company kept me up to date via email. It took very little effort on my part. My electricity bill has [been] $0.00 for the last three months!”—Randy W

“[Tesla Solar] had the statistics and details for me to ultimately negotiate the deal. Once I made my decision, the professional workmanship and wonderful customer service has been second to none. The install team really takes pride in their craft, and the communication has been first[-]rate.”—Al H.

“Recently bought a home that already had SolarCity / Tesla solar panels on the home. With the purchase of the home, there was an amendment to adjust the pricing per kWh for our new contract. We closed in June’21 and now in Oct’21 we still have been charged the original rate, and not the amended rate that was agreed upon on the transfer agreement. I have contacted Tesla many times, only to continue to be told I am right, it should be changed soon….”—Brandon S.

“I needed my solar panels removed because of needed roof repair. I informed Tesla of the issue and submitted the signed removal/installation documents on two occasions however I never received a scheduled date for the work. Due to the urgency of the needed work, I used a certified independent contractor to removed the solar panels and I informed Tesla beforehand of the removal and requested that Tesla reinstall the panels.”—Robert F.

Tesla Solar Installation

Tesla handles your residential solar panel installation from start to finish. Here is how the installation process works:

  1. Site assessment—After ordering your panels, Tesla surveys your roof using remote aerial technology to measure its area and slope.
  2. Design—Before installation, Tesla designs your system to fit your home’s structure and energy needs.
  3. Permitting—Once the home analysis and system design are complete, Tesla will begin the installation, ensuring all necessary permits and inspections are completed.
  4. Installation—You can choose a date for your Tesla solar panel installation. Tesla claims that installation is finished the same day for most systems, and you only need to be at the house during the first hour. If you also ordered a Powerwall+ with your solar system, it will be activated and configured to Self-Consumption Only mode after installation. This means that the Powerwall will produce only enough energy required to power your home and charge your Powerwall.
  5. Inspection—Tesla will work with your local building department to arrange an inspection after installation is completed.
  6. Energization and activation—Tesla then works with your local utility company to receive Permission to Operate (PTO) for your Tesla system. The company states that depending on your location, this may take one to six weeks.

Tesla Solar App

The Tesla app allows you to manage not just your Tesla solar system but any Tesla products from anywhere, 24/7. This includes integrating your solar panels, Powerwall, and Tesla electric vehicles into one user-friendly space.

The Tesla app displays a real-time power flow, showing how your Powerwall, grid connection, and solar system work together to provide energy to your home.

Here are some of the energy preferences you can customize your Tesla Powerwall with using the Tesla app:

  • Self-Powered—This preference lets you minimize your carbon footprint and become more energy independent.
  • Time-Based Control—This setting helps you lower your utility bill and maximize your economic benefit if your energy usage varies throughout the day.
  • Storm Watch—This setting lets you set up your Powerwall to react to inclement weather events that may cause a grid outage.
  • Vehicle Charging During Power Outage—This preference makes your Powerwall and Tesla electric vehicles balance your charging and energy needs during any power grid outages.

Tesla Solar Payment Options

To help customers estimate the cost of installing solar panels, Tesla provides them with a cost calculator based on their location and average monthly electric bill. To help you get an idea of how much a Tesla solar system costs, we received a quote for a single-family home in Chapel Hill, North Carolina, with an average monthly electric bill of $170.

Tesla allows customers to own their system through a cash purchase or loan in select states.

  • Solar loan—Solar loans work similarly to a home or auto loan, with customers paying a monthly fee to own their panels and benefit from solar incentives.
  • Purchase—You may also purchase a Tesla solar system outright if you have the funds available.


System size Wattage Total Price Price After Incentives
System size Wattage Total Price Price After Incentives
Small 4.25 kW $9,647 $7,139
Medium 8.50 kW $19,294 $14,278
Large 12.75 kW $28,941 $21,416
Extra-Large 17.00 kW $38,588 $28,555
Solar Roof (6106 sq. ft.) 13.40 kW $137,300 $101,600

*Prices do not include the cost of a Powerwall home battery.


We received a quote for $11,840, which included the cost of installation and discounts from the 26% federal Residential Renewable Energy tax credit. Only customers who own their solar panels can take advantage of a federal tax credit on the cost of their system installation. In addition to a federal tax credit, some states will offer their rebates to solar customers.
