  • "Great Solar Experience"

    Reviewed May 02, 2020

    We have used GSP for solar systems on two of our houses. Did a great job and highly recommend Tucker as very knowledgeable sales rep. We have been very happy with the system itself and zero electric bill.

    I am so impressed with Golden State Power. Tucker was very professional and asked questions about our needs, looking to the future to make sure we will be covered for the next 25 years. We chose them because they are not a company that sprung up over night, they have been doing solar since 1999. They really cared about the way it looked on our home and they do MORE than solar. We were able to get a new HVAC for our home through GSP and it was a much better price and quality than anyone we had quote us. We are set for the future and absolutely love our solar and HVAC. Their customer service team has been very professional and I highly recommend Tucker and Golden State Power for your solar!

    "Great service and fair pricing"

    Reviewed Apr 15, 2020

    I had Golden State Power add nine more panels to my existing system in June 2019. They installed panels on time at a fair price. GPS did contact me before, during and after install to keep me informed and updated. In Feb 2020 I had an optimizer go bad (existing system that was installed 3 years ago). GPS replaced at no charge to me.

    Great company!

  • "Golden state power, is awesome"

    Reviewed Apr 14, 2020

    When I started work with them, all my questions were answered.
    Darren made sure that I understood all aspects of what was going to be happening.
    I would recommend golden state power, any time.
    It has been a few months since I have had my solar system put in, and they still call me to see how things are going.
    I'm so glad I chose them to install my system.

    Thank you. April

    "Great customer service and easy process!!"

    Reviewed Apr 14, 2020

    We absolutely loved our experience with GSP! We purchased a new home during the summer last year, and with the 100 degree+ summer, our first PGE bill was ridiculously high. We had a few friends who had purchased solar through GSP and raved about it and decided to make the switch! Tommy, our sales rep, was super attentive and made our end of the process seamless. Pricing was extremely affordable, in comparison, we’ve had several friends and family members who have installed their solar with big national solar companies and are paying twice what we are, many of whom are on a lease. GSP’s excellent warranty was also a big plus for us. We are happy to support a local company, and it is so great to be able to call with any questions and get a real person on the line. GSP also constantly monitors our system, and provides a handy app where you can monitor your solar production (which my tech nerd husband loves!) Overall, we are so happy to be paying a small fraction of what we were for our energy and would highly recommend GSP!

    Emily and Darron were great. They answered all of my questions (which were many) and never made me feel like I was a bother. They were very precise on when install will start and finish. It was about 30 days for the entire project to be done from signing the docs to producing power.

  • "GSP"

    Reviewed Jul 12, 2018

    Started with several companies visits with quotes. GPS was prepared and not only answered any questions but offered insight to what we needed. GPS did not bad mouth any other companies but made sure to let us know what we could from them and should expect from any company we chose. Their Finance percentage rate was the seal on the deal. We did have some trouble getting the PTO from PG&E but I am told PG&E works at their own pace. Overall we are happy with our Solar but we are waiting for end-of-the-year true up bill to see how we did with our purchase.

  • "Fantastic Local Company!"

    Reviewed Jul 11, 2018

    I shopped around for awhile and vetted lots of different companies. I narrowed it down to 2 and after talking back and forth with both for awhile and designing different system sizes and comparing prices, interest rates, and warranties Golden State Power was a no brainer. Once they go my business, they kept to exactly what they said they'd do and the timeline. I'm very happy with their equipment and service and recommend them to anyone looking to put solar on their home! My electric bill has been about -$80 the last two months :)

    "Highly reccomend Golden State Power"

    Reviewed Jul 11, 2018

    We spent several years researching solar and installation companies. We were convinced that our roof and placement didn’t lend itself to effective solar installation. Golden State Power designed a system and showed us with computer modeling that it would be effective and give us the ROI we wanted. Their crew were a delight, installing our system quickly and efficiently. Our system was up and running within a couple of weeks from start to finish. We are beginning our third year with our system. We love getting that check at true up time from the electric company!

  • "Couldn't Be Happier"

    Reviewed Jul 10, 2018

    Golden State power did an excellent job and did everything they said. Best part is they have continued to monitor my system and let me know when there was a problem that they needed to fix after the job was completed. Going to be happier with a service they provided.

    I hired Golden State Power to install 28 solar panels on to my roof. It took about 5 days to have all the parts delivered and installed. The crew that worked on my house was very professional, and did a great job. They also cleaned up any mess. I was very happy with their work!

  • "Amazing from Start to Finish"

    Golden State Power was amazing from start to finish. They had contractors build me a large shade structure to mount my solar panels on. The design was efficient and looks great. My experience with the entire team was nothing but positive.

We just answer your question and make sure you know whats coming next. This requires a truly professional staff. You will be glad that you are working with us.

A true professional is created through a process of trial and error, education, and above all, experience. We have a reputation among our peers for being the company that gets the call when things are unusual or specifically challenging. This allows us to improve our craft in ways that others have not.
