I checked the first PG&E bill after installed and calculated. ROI is less than 10 years which I was told before installation.

Great service and knowledgable employees.

Great sales person, efficient installation

Great product that is reliable. This is our second purchase of SunPower products. The first was to reduce our carbon footprint some 10 years ago, this time I wanted to add battery back-up and needed additional panels to ensure the batteries would be fully charged. It works very well here in Florida and I don't really understand why Solar is not required for new buildings given the amount of sun we enjoy, great way to conserve energy.

Great product and warranty. Eco solar did my installation and was very professional.

Great product and Energy Concepts was a wonderful company to work with.

Great and easy to work with. Always communicating about what's going on with your project.

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.
