SunPower vs. Vivint Solar: Which Company Is Better? (2024)

Cost Comparison: SunPower Vs. Vivint

One of the first things most solar customers consider when choosing an installer is up-front cost and long-term expenditure. Below, we’ll explain why installation costs can vary among providers and include some information on relative costs of SunPower and Vivint.

Costs & Financing Options

Every solar installer provides access to different brands of solar equipment. The panels offered vary in efficiency, quality and durability, so the prices of those brands naturally vary as well. 

Some companies — like SunPower — are more expensive than others, in part because they provide such high-quality equipment that can meet greater energy consumption needs.

Companies can also vary in pricing because of the payment options available. Those that only offer cash purchases and solar loans will naturally be more costly up front than those that have no-money-down options like leases and power purchase agreements (PPAs). 

However, they will tend to save you more money on your energy bills over time.

Which Company Is Cheapest, SunPower or Vivint?

SunPower costs more than most of its competitors, in large part because its panels provide the highest efficiency and the company backs them with an industry-leading warranty. Vivint is significantly more affordable, although its panels aren’t as high-quality or efficient.

Both SunPower and Vivint offer these financing options:

• Cash purchase
• Solar loan
• Solar lease
• PPA

These options help keep solar solutions affordable and accessible to most homeowners.

Our Pick for Best by Cost – SunPower

In terms of pricing alone, Vivint is the clear winner. Its prices — even for equipment purchased with cash or through financing — are lower. 

However, SunPower provides much better quality for the money in terms of panel efficiency and warranty coverage. If you’re looking for the most value for your money, we’d recommend SunPower.

Warranties Offered: SunPower Vs. Vivint

Solar warranties are important to consider when choosing an installer. Having comprehensive warranty coverage not only provides peace of mind but also ensures you won’t be on the hook for expensive repairs or replacements in the years following the installation.

SunPower is the best solar company in the industry for warranty coverage. It provides an equipment, power production and workmanship warranty of 25 years. It also covers all repairs and replacement parts that might be needed in that timeframe.

Vivint offers the panel manufacturer’s warranty only, which ranges from 10 to 25 years, for purchased or financed equipment. It also provides a 25-year warranty performance guarantee for energy production. 

If you lease with Vivint — a less appealing option overall — it covers maintenance, workmanship, power production and roof leaks for 25 years.

Our Pick for Best Warranties – SunPower

SunPower provides much more comprehensive warranty coverage if you go with the more beneficial payment options (cash or loan). 

If you prefer to lease your equipment, Vivint’s warranty coverage is a bit better on paper. However, it has struggled with responding quickly to warranty claims, so we’d still recommend SunPower.

Coverage Area: SunPower Vs. Vivint

Most solar companies have specific states or territories they cover, so you won’t have the option to choose a provider that doesn’t serve your area. When choosing a solar company, coverage area is a good first criteria to examine to rule out companies that can’t serve you, saving you some research time. 

SunPower serves the entire country, so virtually every customer in the U.S. will be able to get solar installed by this solar energy company.

Vivint — now Sunrun — has a smaller but still impressive service area. It covers Washington, D.C., Puerto Rico and the following 20 states:

• Arizona
• California
• Colorado
• Connecticut
• Florida
• Hawaii
• Illinois
• Maryland
• Massachusetts
• Nevada
• New Hampshire
• New Jersey
• New Mexico
• New York
• Pennsylvania
• Rhode Island
• South Carolina
• Texas
• Vermont
• Wisconsin

Our Pick for Best Coverage Area – SunPower

Since SunPower serves all 50 states, its coverage area is more than double that of Vivint. SunPower is the far superior option when it comes to coverage.

Solar Panel Performance: SunPower Vs. Vivint

Solar panel performance is an important factor to consider, but customers often don’t check it when considering solar panel companies. More efficient panels tend to cost more up front, but they also usually lead to greater energy savings in the long run, so paying for better efficiency is typically worthwhile if you can swing it.

SunPower solar panels are the most efficient available for home solar power systems. They have an efficiency rating of 22.7%, and are backed by a warranty that guarantees less than an 8% dropoff over 25 years.

Vivint (Sunrun) installs equipment from the following solar manufacturers:

• LONGi — panels only
• Costco — panels only
• Enphase — inverters and microinverters only
• Tesla Solar — panels and Solar Roof shingles, as well as Tesla Powerwalls and EV chargers

These brands are still tier-one and considered a good value, but they pale in comparison to the Maxeon panels.

Our Pick for Best Panel Performance – SunPower

SunPower is uncontested when it comes to solar panel performance and efficiency degradation, so it’s the better choice if you’re looking for high-quality, high-efficiency panels.

Customer Experience: SunPower Vs. Vivint

The customer service provided by solar panel installation companies should also play into your decision. Not only will it affect your experience, but it can also affect the long-term cost of going solar and how much you save on electric bills.

Below, we’ll discuss the service provided by both of these companies and what you can expect in terms of the overall experience.

What Customers Say About SunPower

SunPower has mostly positive reviews and an A+ rating with the Better Business Bureau (BBB). Given the company’s size, this speaks volumes about how it manages customer relations.

Many of the company’s positive reviews mention things like:

• Fast installation timelines
• Quick responses to warranty claims
• Professional and timely installation crews
• Knowledgeable staff willing to educate customers on solar and solar incentives, including the federal tax credit

SunPower also has some negative reviews, most of which mention that the company is too large to provide optimal customer service. There are some complaints that the company is slow to respond to customer inquiries, that there is confusion among the different departments and that activating the solar panel system can be delayed in some cases.

Below are some reviews that paint a clearer picture of SunPower’s service.

“When I decided to go with solar in my house, I contacted six companies to give me a presentation and proposal. SunPower sent a very knowledgeable sales consultant who spent plenty of time answering every question I had and more. They manufacture their own equipment (panels, battery backup, etc.) in the USA. Huge advantage so you deal with a single company for service and warranty. Their panels are 400 watts (other companies 300-350), requiring fewer panels. The entire process was flawless from beginning to end and I am enjoying energy independence.” — Pablo L. via Yelp

“I have a love-hate relationship with SunPower. On one hand, the product manager was great, the installers friendly the solar system looks clean and neat. On the other, customer support is horrible. They forgot to turn the monitoring system from install mode to Wi-Fi. Luckily, I was able to get the app working on my phone. I know this sounds petty, but I spent thousands on the system and part of that is the monitoring.” — Adam S. via Yelp

What Customers Say About Vivint

Unfortunately, Vivint has a long history of customer complaints and a reputation for poor customer service. Many customers complain about:

• Poor communication, especially after the installation process
• Slow response times to warranty claims
• Misleading marketing and lease-first business model that pushes less beneficial solar leases and PPAs
• Overly aggressive sales tactics
• Delays in installation and solar energy system connection

There are also some customers who are pleased with the service they get from Vivint, so your experience will likely depend on the representative assigned to your project.

Below are some customer reviews that give an idea of the service you might get if you decide to go with Vivint.

“Go solar at no cost! Vivint Solar is the way to go! We’ve had our photovoltaic solar for over seven years now, and we’ve had steady savings since we installed our units. Their service is very thorough and dependable. The manager goes out of his way to service his clients and explains thoroughly the advantages of having photovoltaics.  They now have solar battery backups in case of blackouts and power outage[s].” — Emmie A. via Yelp

“By far the worst business I have ever worked with in my entire life. Save yourself the headache and do not work with Vivint/Sunrun. I removed my panels as I was rebuilding my home. Six months later, construction is complete and I requested them to re-install the panels. I [paid] the re-design fee. Fast forward six more months… no progress. I constantly keep calling them asking for an update and their… out-sourced customer service constantly keeps telling me, ‘we will look into it and get back to you.’” — Darren D. via Yelp
