Sunrun vs Tesla: What’s Better?

Sunrun vs. Tesla: what’s better? Both Sunrun and Tesla are top-of-the-line solar panel companies, but which is better? Sunrun is cheaper, but Tesla has a wider range of products. Sunrun is more environmentally friendly, while Tesla is more efficient. 

Sunrun is easier to install and has a better warranty, while Tesla is more reliable and provides more power with a single panel.

Sunrun might be better for those who want to be more environmentally conscious and save money, while Tesla might be better for those who want the best value for their money.

So which do you choose?

Set of Solar Panels

Solar is becoming America’s fastest-growing renewable power source. Many homeowners realize the benefits of utilizing solar systems to light and power their properties.

Installing solar panels on residential or commercial properties will give a more energy-efficient alternative. Solar electricity has significantly lower operating costs as far as maintenance is concerned.

Following the increasing demand for solar cells, numerous manufacturers have entered the solar panel production business with high-quality products such as Sunrun and Tesla.

What is Sunrun?

Sunrun Landing Page

Sunrun is a solar energy company known for organizing the installation and maintenance of solar panels for homes and businesses. They offer several services, including home solar, business solar, and solar storage solutions. Sunrun is one of the largest solar energy providers in the United States.

Sunrun Batteries

Sunrun helps install solar panels, but they also take care of solar home batteries. They are one of the leading providers of home batteries in the United States. Sunrun’s home batteries are known as the Brightbox.

The Brightbox is a lithium-ion battery that stores energy from solar panels. The battery can provide power to your home during a power outage or high electricity rates.

Third-Party Ownership

Sunrun is a third-party solar company, meaning they do not produce, own or operate any solar panels. Instead, they provide a platform for homeowners to connect with installers, who take care of installing and maintaining the panels.

Sunrun takes care of billing, customer service, and other logistics. For this reason, they can offer lower prices and more flexible financing options than Tesla.

Systems and Financing Multiple Quotes

SunRun offers systems and financing multiple quotes so that you can find the perfect solar system for your home. Tesla also offers solar panels, but their systems are more expensive. If you’re looking to save money on your energy bills, Sunrun is the best option.

Solar Lease

Sunrun is also a solar lease company allowing homeowners to go solar for even less. Sunrun owns, maintains, and monitors the solar system, while homeowners enjoy lower energy costs for the life of the lease. Sunrun has a hassle-free process and offers competitive rates.


Sunrun offers a 20-year warranty on their solar panels, while Tesla only offers a 10-year warranty. Sunrun also guarantees that its solar panels will produce electricity for at least 25 years, while Tesla does not make any guarantees about the lifespan of its solar panels.


Tesla solar inverter comes with a number of features and benefits that may be appealing to some homeowners. For example, they are designed to work with Tesla Powerwall batteries, which can store energy collected from the solar panels for use later on.

Features of Tesla Solar Panel Systems

Historically Tesla has used Peak Duo BLACK Sun Power cells by Hanwha Q CELLS, specifically Q.Power Duo BLkG6+ modules.

Eventually, Tesla said it was moving towards solar panel technology. Tesla’s solar panels come in two models — an H Series and an S Series. We examine the performance of these panels:

What Do You Get from Tesla Solar Panels?

Tesla also offers four solar panels ranging up to 4.8 kW. Tesla will include power walls with their solar panels for storage in peak periods or after sunset.

The panel is characterized by a sleek, slim design and is easy to install and use. That said, I think Tesla installations are, in fact, much more intrusive.

Tesla has a lot to gain. If you are concerned about who manufactures your products, how long their lifespan lasts, or how effectively it is vital.

Tesla Batteries

Tesla batteries are some of the most popular in the world. They are used in a variety of applications, from cars to homes. Tesla batteries are known for their high quality and performance – as well as occasionally bursting into flames.


Tesla fans have been arguing over Tesla panels being “stronger” than most of its residential panels.

In truth, the solar panels produced by Teslas aren’t quite as “amazing” as they seem, rather they are just larger than most commercial solar panels.

In this respect, the panels have more surface, which allows for more solar cells in the structure, which in turn improves the power intake. That doesn’t mean Tesla uses any revolutionary tech, just larger amounts of existing tech.

The same solar cells produce as much power as other solar panel products available on the market – and less compared to some solar panel manufacturers.

10-Year Warranty

This comprehensive warranty covers your Tesla solar installation and installation of power walls, solar inverters, roof mounting, and leaks.

There’s an extensive manufacturer guarantee, which means there are just a couple of companies to deal with for a problem.

Generally speaking, your inverter will be from another company with any other solar panel system. It could be from a different manufacturer, so there are several companies’ warranties you might have to deal with.

A comprehensive warranty from an electric car manufacturer, for instance, Tesla, could reduce your costs, as well as the amount of paperwork you have to fuss with.

Performance Warranty

As your solar panel technology ages, the batteries will be able to hold less and less charge. Generally speaking, warranties describe the extent of degradation from sunlight with aging.

Tesla’s warranty says their panels can operate at 80% of their original power after a full year of use. The battery capacity will supposedly remain constant for the rest of the warranty life.

Tesla Solar Loan

The Tesla Solar Loan functions as an ordinary loan for solar energy. You get credit from Tesla, paying them back each month for a specific duration.

With the Tesla loan for business, your company owns your system, which allows you to benefit from solar tax credits and other incentives, such as solar energy rebates.

Sunrun Solar vs. Tesla Solar

When it comes to solar energy, there are two big names in the game to consider: Sunrun and Tesla. But which one is better?

Let’s take a closer look.

Installation Costs

Installation expenses vary significantly depending on location type and brand of solar panels. Tesla Solar charges customers depending on location, current power bills, and installation. Many homeowners consider it one of the most affordable options available.

Tesla solar has been able to offer a cheaper product by relying on no door-to-door sales and cutting out middlemen. The company already has a solid reputation, so customers can easily find their way in.

However, solar panels and rooftop solar panels sourced from Sunrun are a little cheaper as they need to be marketed in many different ways. But it is still among the first companies to offer customers solar loan contracts and energy purchases.

Real-World Performance

Tesla solar panels have temperature coefficients of 39 percent, meaning the energy output drops to 0.39 percent when the temperature goes below -25 degrees Celsius.

Sunrun’s energy efficiency is 0.258 percent lower by degree Celsius and is, therefore, less effective at -25 degrees Celsius.

Tesla solar panels are also more durable in the real world.

Panel Type and Design

Solar panels come in a variety of sizes and shapes. Among them are monocrystalline, polycrystalline, and thin films.

The monocrystalline panel is the most efficient due to its square cells with a black tint that can absorb light quickly. Polycrystalline sheets are cheaper but less efficient because their tint is darker instead.

Thin films are lightweight, cheaper, and easier to install, although this option can be less efficient. Solar panels from Sunrun come in three different varieties, whereas Tesla focuses exclusively on mono and polycrystalline panels.

Solar Panel Efficiency and Output Rating

The efficiency of the solar panels determines the amount of energy a solar array generates. Most sun cells have output rates ranging from 200 to 600 watts.

Here’s the gen; Telsa solar cells are rated at 340 watts and have a 21.76 % efficiency. This rating is the highest in the business, and Tesla solar panels provide more power than a single panel.

The average Sun Run panel is rated at about 320 Watts. Its efficiency ratings range from 15 to 22 percent.

Manufacturer Warranty

When buying an electric and wind turbine solar installation system, you need to check the available warranty.

Solar panels are generally built for the longest, but a warranty covers the repairs and replacement of any damaged parts if any of them occur. Tesla solar panels are offered for ten years with full warranties.

These include the cost of installing solar power panels, solar panels, and roof mounts. Tesla repairs your roof for free for all roof damages resulting from rooftop installation. The firm also provides 25-year performance warranties.


Tesla’s services are unbeatable. It produces Solar panels and owns a team of installers. In addition, they offer to lease solar panels. Sunrun produces no own solar panel and usually subcontracts the installation of the system to their customers.

If your solar panel is purchased at Sun Run, likely, your installer might not have the same level of expertise (and certainly not the same level of practice) as Tesla’s installers.
