According to our March 2023 survey of 1,000 homeowners with solar, a Sunrun solar system costs $15,000 to $20,000. These figures reflect a cash purchase, and Sunrun is known for its leasing options. With a lease-based system, you pay nothing upfront, have a set monthly payment and will never own your system. As a result, you will save more over time by buying your system outright or with a loan.

Tesla solar panel systems cost around $15,000 to $30,000. The company also offers solar financing options, including loans and leases.

The above numbers are based on several factors that can differ from buyer to buyer. The final cost of your solar system will depend on your system size, provider and location. However, you can lower your overall cost by claiming incentives and rebates, like the federal solar tax credit.

It’s nice to know there are companies that place a priority on customer care — Sunrun is a wonderful example.” —Viola U. via the BBB

The presentation was outstandingly professional. The installation was quick, and my system is already producing as expected.” —Landon via the BBB

“I met with over a dozen companies before deciding to ‘bite the bullet’ and go with Tesla Solar. Oh my goodness, did I make the right choice! To begin with, its presentation was unlike any other company I interviewed — it really impressed me, and the interactive approach was A+! I’m overjoyed to have gorgeous black solar panels on my roof! The solar panel installation was painless, and the installation crew was extremely friendly and professional!” —Vance A. via the BBB

“An absolutely terrible company to deal with. Due to a problem with the equipment, [Tesla] shut down the system for two months. [Tesla] still billed us (an estimated usage) for the time the system was shut off. I called customer service to ask when the system would be repaired and they didn’t know. The customer service is one of the worst I’ve ever dealt with. I wish I worked with another company.” —Lee J. via the BBB
