  • NABCEP Certified

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

Multiple Financing Options

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

Easy to work with and responsive to all questions, before and after the installation. Knew all the regulations, Fed, state, and city so there were no surprises in terms of cost. Worked well with the roofing company in terms of setting a schedule. Did the work quickly and cleaned up after themselves. Set up the app for me.

Keenan S and the SunPower team were the epitome of professionalism throughout the entire process of quoting, planning, installing, credits and rebates. To the penny, SunPower's quote was accurate. From our $1000 SunPower cash-back to our tax-rebate, everything went perfectly. Keenan is a great representative who believes in his company, says what he is going to do and does what he says.....as good as it get. Thank you Keenan!

Overall, I am very satisfied with SunPower by Solar Technologies. The sales representative was helpful and did not put pressure on us to make the purchase. She was also very good at helping us to get the right system for our needs. There were delays in getting permits due to Covid and that is understandable. There was also a delay in starting construction due to issues with Tesla's ability to provide the Power Wall battery. The company did a poor job in keeping us informed about the delay and letting us know what options were available to us. I had to call to find out abput the delay a few months after we got the permit approved. Then I found out that I could get the panels installed while waiting for delivery of the Power Wall. Installation was great and done very professionally. I would have given five stars except for the company's not keeping us informed during the delays.

The installation was not done appropriately. There were panels that were not tightened down and I discovered them when inspecting the panels. Also, I was told certain things could be done that I requested, that when it came to the actual installation, it was determined that it could not be done. This after I repeatedly asked if it was certain that the electrical line could run though the attic, not on the roof. Obviously, I was not in a position to cancel the project at that time, not that I would have anyway. But, there was a lack of transparency from my perspective. Also, I was told I could evaluate how each panel was functioning from the Sunpower app. When I checked the app out, it was not possible and that Sunpower (Solar Technologies) monitors the function of each panel and would contact me if there were a problem. I would not know, since I have had no follow-up from the company.

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.

I have already recommended this company to friends! They are a very trustworthy company. Installation had a few hiccups because the city of Oakland sent an inspector that required things I didn't think were necessary. Other than that, the glitches got worked out and everything Now that my panels are up and running, I'm seeing that they are producing at the estimated rate I was given which is a good sign. The Tesla batteries are performing well and overall the equipment is great. Their customer service is great overall. They are very accommodating and responsive to your potential problems.

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.

The system works. However, there were defects that did not allow for optimal electric cost saving. It took company a long time to make repairs. Solar Technologies also requested multiple change orders that did not make sense. We had to push back on these change orders.

While the system works the original design was very flawed. The panels were placed where the sun only hits in the afternoon whereas half should have been on an adjacent roof. The trueup last year was over $400.00. The salesperson indicated tome that his design would be sufficient to power any future needs even if I installed an outlet for an electric car. Obviously that was not a true statement.
