  • Additional Services
  • Multiple Financing Options

  • High Positive Review Rating

SunPower Master Dealer

As the only SunPower Master Dealer certified in the Bay Area, Solar Technologies builds solar energy systems that are almost unmatched by many of its competitors. Solar panels from SunPower are the industry’s best, averaging around 22.8 energy efficiency, and built to withstand extreme temperatures. Companies like Solar Technologies that achieve Master Dealer Status achieve high marks in the following areas:

  • Technical Experience
  • Installation Quality
  • Customer Satisfaction
  • Financial Health
  • Service and Support

25-Year Power and Product Warranty

Solar Technologies also protects its solar installation systems through SunPower's Complete Confidence warranty. This guarantee applies on three fronts: first, it ensures that the system will perform at peak efficiency and performance throughout its entire projected lifetime (25 years). In the event that any system component significantly underperforms, the company will service or replace the part for free.

The second area the warranty protects is against system or solar product defects. In the event that a solar panel, solar inverter, or other system component is revealed to be damaged or defective, Solar Technologies will replace it at no cost to the homeowner.

Lastly, the warranty covers all the labor required to build the system; in the event the solar panel system requires maintenance or repair due to installation errors, the company will provide this service at no cost to the homeowner for the lifetime of the system.

Additional Services

In addition to installing quality, industry-leading solar panel systems, Solar Technologies provides homeowners with the following services:

  • Solar Energy Storage — includes both SunVault Storage by SunPower, and the Tesla Powerwall to harness and store the SunPower Equinox systems surplus energy to be used in emergencies

  • Ongoing Maintenance and Monitoring — allows customers to monitor the performance of their system, and request maintenance appointments when needed

SunPower by Solar Technologies provides multiple financing options to help homeowners make the switch to solar. In addition to direct purchase, which requires a significant upfront investment for immediate solar panel ownership, the company also allows homeowners to finance through a zero-money down third-party solar loan, or to rent the solar panel system through a solar lease. Each of these options carry inherent advantages and drawbacks, and customers are encouraged to speak with one of the company’s energy specialists to determine the best financing route for them.

NABCEP Certified

They rushed into the job without giving time to evaluate my roof. It clearly needed replacing. A few months later when I did replace my roof it was no longer eligible for a tax credit Plus they quoted me about as much as the entire solar cost to remove and reapply the panels. They did not credit my college which was my motivation for picking them. When I pointed this out to them they ignored me.

Jeff guertin San Leandro, CA

I was happy at first but was upset with them later. Part of my frustration was my own fault due to me not downloading the app or Taking in information better. One problem that seemed to repeat was that different parts of the company were not communicating with each other well enough. When my new panel was installed there was a miscommunication between the electrician that caused the project to last 3-4 days instead of 1. Later I was irritated when I belatedly downloaded the app and saw my solar not working during the sunniest part of the year. Issue was that I was given permission to operate and told so in an email, but I was not aware that my panels were turned off before that event and it was myself who had to turn them on. Found it irritating, the gap between what one person thought they were telling me and what I really understood. I know the issue was explained to me but the clarity of the issue and the coordination of it was not done well.
