Are Tesla Solar Panels Better?

When looking at customer reviews of Tesla solar panels, it appears the early reviews were below average, but the recent reviews are overwhelmingly positive.

It appears Tesla had a shaky start getting into the solar side of their business, but they’ve been improving their processes, and customer service, over time.

For those looking for the most advanced solar technology, at the most affordable price, Tesla solar panels are the best choice.

Sunrun Solar Panels

Sunrun solar is actually a finance company that specializes in solar power purchase agreements (PPAs) and solar leases, according to The Solar Guys. This essentially means that Sunrun owns the solar panels installed on the homeowner’s roof; the homeowner just pays Sunrun a monthly fee for using the solar panels. However, Sunrun now offers an ownership option for customers who wish to have their own system, although this is not as common.

Cost of Sunrun Solar Panels

As mentioned above, homeowners only have to pay a monthly fee to rent Sunrun solar panels; the exact costs will depend on your average electricity use. As far as installation goes for those wanting to own the system, you can expect to pay between $15,000-$29,000 upfront.

Pros and Cons of Sunrun Solar Panels

Like Tesla, Sunrun’s solar panels have their own set of pros and cons worth considering before making any commitments:

Pros of Sunrun Solar Panels

  • Sunrun’s solar panels are incredibly durable, and the company performs regular tests to ensure that. In fact, a 2017 hailstorm only damaged one panel out of the 3,000 that were in the area.
  • Because Sunrun continues to own the panels as you use them, they are responsible for the costs of installation, maintenance, and permits, meaning you should not expect any exorbitant fees upfront or during the life of your Sunrun contract.
  • Sunrun offers plenty of flexibility in the way customers can pay their monthly bills.
  • Sunrun will monitor your system for you—no app needed.

Cons of Sunrun Solar Panels

  • The solar panels have a shorter warranty period, spanning 20 years.
  • Customers are required to sign a contract to use Sunrun’s solar panels. In the event you no longer want to use your solar panel system, you will have to pay for the rest of the monthly costs left on the contract in addition to the costs of the system’s hardware. The final cost for ending a contract early will vary but can be as high as $25,000+.
  • Sunrun’s Brightbox, their version of a battery storage solution, is said to be limited compared to Tesla’s Powerwall.
  • Customers have complained that Sunrun’s customer service is difficult to reach when needed.

Are Sunrun Solar Panels Better?

According to Consumer Affairs, Sunrun is actually a lower-rated company than most solar energy businesses, including Tesla. Out of 130 reviews, Sunrun received a 2.4/5.0 rating overall.

However, despite these reviews, if you want to save on upfront costs and not have to worry about regular maintenance, Sunrun seems the way to go over Tesla. And although Sunrun requires locking into a contract, if you do not plan to move to a new home anytime soon, this should not pose a problem.

When it comes to solar panel systems, two of the top choices a homeowner could go for are Tesla and Sunrun. The two companies are giants in the solar power business but offer their own pros and cons.

Tesla has quickly become a big name in the solar industry. They have an unbeatable price, backed by a price match guarantee, and somehow do it all while offering the most advanced solar technology on the market. Having the ability to control the system through a mobile-friendly app, and the durable, aesthetically-pleasing appearance of the panels, may make it well worth the investment.

Sunrun, in contrast, has minimal upfront costs, but they require customers to lock into a contract, which may pose a financial challenge should you decide that you no longer wish to use their services. However, because Sunrun owns the solar panels, the maintenance and installation process and fees associated with ownership are theirs to handle, so you will have less to worry about.
