good company, good people and good products

SunPower's customer service is genuine and effective

Definitely the best solar panels on the market. When I am making a large investment for solar panels, I want to make sure they have the best warranty, and are the most efficient. SunPower definitely hits the mark with the product and the warranty.

Great process from start to finish. Up front and honest. My system looks and performs better than expected.

Good product & service; productivity of the panels so far seems excellent

Sunpower had my 86 year old grandfather sign a 20-year lease. He died 4 years later and now this lease is the responsibility of his next of kin. Predatory? Beware of this company.

Piece of crap company. Once getting my load controller installed I had to turn it on and off to be able to have my dryer work. This was before the system was activated. Then I had to turn the controller off to have heat, hot water, dryer, stove working in my house. I had to pay for an internet upgrade and now having to look into pest control issues with pigeons and mites because the company wants me to now pay for bird netting through them or I void my warranty.

good system reliable, good performance no breakdowns

Excellent high performance panels.They perform better then the other manufacturers i am familiar with.

excellent customer service and follow-up throughout the process, professional installers but never received final review of system once it was installed

Excellent & efficient staff. Very helpful through entire process

Everything from start to finish was as promised. They deserve 10 stars

Efficient, one-stop shopping with great products

Easy to deal with and provide a quality product.

Best panel available - most power produced and looses least amount of production over time.
