Sunpower is the best choice that I have made. I am running my air-conditioning in 3 rooms and I am only paying less than $100.00 per month thanks to Sunpower. In fact they are only covering 75% of my home due to my neighbor trees partially blocked.

I never got to see any product or talk to an installer. After setting up a consultation, they called back a few days later and said we were not good candidates for solar, even though my roof has is sunny all day. I am frustrated that I can’t even get someone out here to tell me why or explain what they think the problem is

Overall my experience with SolarCity/Tesla has been amazing. Great customer service every time I've called to get a status update or help move the process forward. Installers that came out were contracted (around March 2019) and did an amazing job. SolarCity/Tesla upgraded me to the newest panel for free as well due to supply issues (SC330 instead of SC320), and my panels are doing amazingly!

The Final Word

Availability
SunPower equipment is currently available in 40 states, while SolarCity solar systems are offered in 20 states.

Individuals in Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Maryland, Massachusetts, Nevada, New Hampshire, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Texas, Utah, Vermont, and Washington D.C. have access to both SunPower and SolarCity solar energy systems.

SunPower systems are also available in Florida, Georgia, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Michigan, Minnesota, Missouri, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Virginia, West Virginia, Wisconsin, and Wyoming, while SolarCity does not offer service in these states.

SolarCity operates in Washington, while Sunpower does not.

Payment Options
SolarCity allows customers to purchase a solar system outright, finance a system with a loan, lease a system, or utilize a system by signing into a power purchase agreement (PPA).

SunPower also allows outright purchases, loans, and leases, but the company only offers PPAs to commercial customers, which means residential SunPower customers do not have access to the PPA option.

Equipment
SunPower and SolarCity both manufacture their own equipment. SunPower holds 750 solar technology patents and makes the highest efficiency solar panels currently available on the market. According to testing, SunPower’s panels deliver 44 percent more energy per watt than competitive products and can maintain their production better than other panels in partly-shaded conditions. In addition to being extremely efficient, SunPower solar panels are all black and designed to blend in better with the rooftop than traditional blue panels.

While SolarCity’s panels are not on par with SunPower’s in terms of efficiency, the company does produce and offer solar shingles, which are a unique product in the industry.

Installations
SunPower performs its own installations in select areas of California. Outside of these areas, the company’s installations are performed through a network of dealers. In addition to performing the installation, the dealer also acts as the customer care center for the life of the solar energy system.

SolarCity, on the other hand, performs all of its installations with its own in-house team. However, several customers have reported issues with delayed and incorrect installations.

Warranties
SunPower offers industry-leading warranties, including a 25-year warranty on equipment, a 25-year warranty on labor and installation, and a 25-year warranty on system performance.

SolarCity provides its customers with a 20-year warranty on equipment, a 10-year warranty on labor and installation, and a 25-year warranty on system performance.

Battery Storage
SunPower does not produce its own batteries, but its systems are compatible with Freedom CPAP batteries, which are manufactured by Battery Power Solutions.

SolarCity offers Tesla Powerwall batteries to its customers, which are designed to seamlessly integrate with the company’s solar equipment.

Referral Program
SunPower’s referral program rewards customers with $100 for every qualified homeowner they refer who has an in-home consultation, regardless of whether or not the referee actually purchases a solar system.

SolarCity pays customers $250 for each referral that installs a solar energy system.

Recommendation
SunPower and SolarCity have similar offerings in terms of payment options—although SolarCity provides PPAs for residential customers while SunPower does not—and battery storage. 

While SunPower does outsource a majority of its installations to certified dealers, the company offers some of the best solar equipment available and incredibly lengthy warranties, which is why SunPower is recommended over SolarCity for those who live within a state where its products are available.
