Had them quote me on solar and, while I ended up not buying solar at all, the staff were extremely helpful. The quote was well organized, provided me with a lot of information, and the no-pressure sales was a welcome change.
If I do ever decide to put solar on my house, I’m definitely going with Advance Power Redding.

Very clean install. Crew did nice work hiding the electrical routing.

My one star review: 3 Strikes and you’re out. Darn it. I liked these people. Yet after several blunders I cannot recommend. They installed my array 1.5 years ago. The salesman was great. Easy to work with. When the team came to install, the foreman was testy and argued about where to install despite what the salesman and I agreed to. Ultimately he relented but was very rude. When they did the trenching, they did not compact the fill. Ultimately, when it rained it left a deep trench across my driveway. I call the salesman. He came out and agreed it was not right and promised to fix it the next day! They never showed up. Recently I thought about adding 8 panels (they undersized the array). I ask to get an estimate, no one ever called. Don’t waste your time with these folks.
Addendum: They did come out, apologized for issues, and gave a great bid. Sometimes we need to forgive mistakes.

Excellent service, ongoing friendly knowledgeable assistance. Job completed very quickly. Highly recommend hiring them for all your solar needs.

Were extremely knowledgeable and helpful! Honest company doing great work!

I have had they extreme pleasure of working with Greg and his crew on a small project that started with 1 panel and it grew into a system that ran a house as well as a couple outbuilding s with a washer, drier, refrigerator, freezer, a submersible well pump and even a small milking machine. Greg not only kept everything affordable, but also provided and education that made adding on to the system a breeze. Now another but larger project looms on the horizon, the first and ONLY call will be to Advanced Power. That should be the call you make as well.

These Guys rock!. Professional people who do a quality job. I am now fully off grid and functioning with a piece of mind that came to me at a great price. Very professional staff, great communication throughout every step of the process. There was a fire that threatened my home and burned my property on the same day installation was to take place, their communication as paramount. They called each morning willing to do the job that day, because we had missed the appointment, they came out within hours of the roads being opened back up and were very supportive of my situation. They also handled all of my solar permits with ease and kept me in the loop at every step. Their installation is VERY clean and sanitary, everything is routed perfectly. I have told everyone how great Advanced Power and their staff is. We will be doing business in the future for sure! Major thanks to Greg, Berek, Everett, Pete, everyone at advanced power for their top notch communication skills and workmanship!

We rarely write reviews, but in Redding, not many businesses stand out as exceptional. Greg was so above & beyond we hope by giving him a plug it will encourage others to use his services. We have used his crew a few times in the past years for helping install & maintain various off grid solar components, but we had never interacted with Greg before (we were always happy with his crew, especially Berek).Anyways our garage with our off grid solar system was cooked in the Carr Fire. We called him up and he was up the next day to figure out how we could get power back to our house with our main goal of getting our well pump working again to get some water to our many fruit trees that managed to survive. Once he got the system working he found out our well pump was fried as well (as well as a few other of our DC components) and after Greg contacted the local well company and found they were a week out he installed a new well pump himself and did all the electrical and plumbing work. Our home is a do-it-yourself build (every contractor dreads these – and not by us, we bought it that way) and its pretty confusing system and wiring. But its up and running with all new components and we couldnt be happier, lucky for us technology has made a big jump since our original install and it appears to be so much more efficient and easy then before. We would not consider using another solar company. Thanks Greg & Crew!

Pete gave us excellent customer service. He is a fantastic resource. We highly recommend doing business with Advance Power. We will be doing more business with them.

I am off grid and needed an updated solar system for a rental residence and one for a barn/shop. I was referred to the owner, Greg Tomsik at Advance Power. He did a great job and his price was fair. He is professional and has helped me with referrals on other matters. His staff are easy to work with and I feel like they have all become friends. I couldn’t be more satisfied.

Had them install solar panels at our house in May, 2017. First Class service. Did what they promised, when promised, with no surprises. Workers were tidy and respectful. Anthony and Berek kept us informed and answered all our questions throughout design and installation. System performs as promised. Definitely recommend.
