Jordan Grimmer | Senior Editor

SunPower and Sunrun are both well-known names in the solar industry. SunPower has been in business since 1985, setting it apart as one of the oldest and most reputable solar companies in the industry. Sunrun was founded in 2007, but even though it has been in business for a shorter period of time, it has grown to become one of the nation’s largest residential solar companies.

SunPower is the top-rated solar company on BestCompany.com based on reviews, but it is worth noting that it has substantially more reviews than Sunrun, which affects a company’s overall rating. But, both Sunrun reviews and SunPower reviews are favorable with the majority of customers giving their chosen company a 4-star or 5-star rating.

This is the third time you have asked for me review, once again I will provide you with my honest opinion and feedback. We looked at a number of solar providers and SunPower was the best option for our home. We installed the beginning of December 2022 and the panels overproduced what we used for the month exceeding our expectations. Our son and 3 of his friends have also moved forward with SunPower and have either installed or are waiting to get installed. I highly recommend SAVKAT ( local dealer) and SunPower. The panels are made here in the USA which I like.

Stay far away from this company. I’ve had my system for four years. I’ve had repeated issues. Customer service is terrible. I’ve had to call multiple times. The agents speak heavily accented English that is difficult to understand and they always promise that someone will call me back. No one ever does. I wouldn’t recommend this company to my worst enemy.

Fast, reliable, up front. They walk you through the whole process and they are there ever step of the way, even after install. They address any questions before during and even after the process, I can still call them up for trouble shooting. They stand by their work. Easiest process ever and felt I paid for what I received. No hidden anything.

The Final Word

SunPower and Sunrun are both great options for your solar energy needs, but there are a few differences between the companies to be aware of as you compare solar companies.

Industry-leading solar panels

Both SunPower and Sunrun offer customizable solar panel systems that will be fitted to your specific home, but SunPower’s solar panels are known to produce and maintain energy beyond typical solar panel systems from other companies.

SunPower offers customers its M-series solar panels which generate and deliver 60 percent more energy per watt than competitor panels. This means that the company could install fewer panels on your roof while maintaining high energy production. The M-series panel performance also makes them a good option if you live in a cloudier region or shaded area.
 
If you are concerned about your home’s curb appeal with newly installed solar panels, SunPower’s panels are also more aesthetically pleasing than those of its competitors. SunPower’s panels are black, and have minimal and sleek mounting systems, resulting in a solar panel system that blends in with a roof. Traditional solar panels are blue with highly visible mounting systems.

Solar battery storage

SunPower offers a battery storage option called SunVault™. The SunVault system pairs with SunPower Equinox®, the company’s residential solar power system, which charges the SunVault battery during the day when the sun is out and can be discharged at any point if the homeowner needs it. SunVault storage is covered by a 10-year warranty.

Sunrun offers a battery storage option called Brightbox. The system can be purchased or leased, and provides homeowners with a reliable power source if there is a blackout.

Solar monitoring

SunPower and Sunrun both provide mobile apps that can help you monitor and track panel performance. The SunPower app, mySunPower™, and Sunrun app, mySunrun, are both available for iOS and Android devices.

SunPower solar energy systems also include a consumption monitoring kit that allows homeowners to track their own energy consumption.

The bottom line

SunPower and Sunrun are both reliable solar companies that offer customizable solar solutions. What your decision might come down to is whether or not the company’s services are available in your state — SunPower has a much wider state coverage area than Sunrun. Check which company is available in your state of residence.

SunPower does set itself apart as an industry frontrunner with more than 30 years of experience. In addition, it has high performing solar panel systems that could help you generate and maintain more energy.
