Services
If you own your home why not own your electricity also? California is known for its sunshine so let that abundant natural resource work for you by installing a panel system from Golden State Solar. Solar panels absorb the energy produced by the sun and converts it to electricity for you to use. A solar panel system is your very own personal power plant that just so happen to run on free fuel.
Solar costs less than traditional electricity in many markets, whether you choose to purchase your system outright or pay as you go. We offer a range of straight forward and simple financing options, which makes going solar stress free and affordable. Simply put: awesome. We only use modern, low-profile designed panels that integrate elegantly into your roof.
My brother had used Golden State Solar and highly recommended them to do mine. The first thing that really impressed me was the owner came out and walked us through the whole process. All the other companies we received bids from only did emails and phone calls. Secondly, every time I called or emailed Tim, I would get an immediate answer or a call back the same day.

I had a small electrical job that needed to be done. Tim was responsive, scheduled a meeting, confirmed the previous evening regarding his timing, and showed up right on time. Tim definitely took precautions (Covid 19 time) by wearing a mask and making sure there was no contact (I miss the shaking hand days). Left the work area neat and clean. I would definitely recommend Tim for any project.

We cannot say enough positive things about Tim Dominguez and his company, Golden State Solar. We were in a bind and needed to have a solar system removed quickly. Within 24 hours, Tim and his crew removed the solar system, patched the roof and did it all in less than three hours! He came at exactly the time he said he would arrive and did a great job. We will have solar installed by Golden State Solar at our new home!!! You could not find a more efficient, curteous, and competent company.

I recently bought my house and everything was going great until I found out my Microinverters were not communicating to my Envoy. I desperately called the recommended Service Installers from Enphase. I couldn't get anyone on the line. The original installers went out of business, so I reached out to Golden State Solar. Which I have seen bill board ads by my house. I called and like that, I had Tim out today to troubleshoot the issue. I was not home at the time, but my wife mentioned that he was very professional and a nice man. I gave him 5 stars because I felt my need was very important and

I called Tim @ Golden State Solar to see if he could help me with moving my solar inverter. A little back story is this It's a Solar City system ( Tesla now ) I reached out to Tesla a month ago to move the inverter A MONTH . Spoke to Tim on Wednesday and he was out the next day and completed the job in around 4 hours. Very professional and affordable as well. Thank you Golden State Solar we are very pleased with your work. They even cleaned my solar panels while they were on the roof at no added cost. Highly recommend them!

They were wonderful. We had lost production from many of our panels and when we called the company that did our installation they had gone out of business. Tim fit us in the next day troubleshot our system and fixed it for a reasonable price. Additionally he spent extra time with us to explain clearly what had happened and showed us photos. We were so relieved to have it fixed. Very positive experience with Tim and Golden State.

We hired Golden State Solar on the recommendation of a family member whom had used them for their solar. We found them very easy to deal with and answered every question we had with great detail. The crew that showed up was very professional and Tim the owner was there the entire time to make sure everything was built correctly. Not a single problem arose during construction and when the city inspector was there I overheard him say what a beautiful job they had done. We are so happy that we no longer pay a PGE electric bill and even happier that we hired the right contractor to install our solar

We just upgrade our electrical panel for our new hot tub. Tim, from Golden State Solar was awesome! He did a huge amount of work in just 2 days! Nicest guy and he brought his son to assist, they both worked non-stop in 90* weather! We couldn't be more pleased that we chose Golden State Solar! In the future, if we ever need any electrical work again, I wouldn't hesitate to call him! Very professional and personable.

While getting quotes for solar for our home, we found many unprofessional and extremely corporate companies just looking to make a sale. Many of the companies we found were either subbing out the work or were very quiet about the quality of their panels and installers. Do not have the time to be checking lic #s and insurance credibility before they climb on our high roof.
Tim and his team were OUTSTANDING. Educated in all aspects and honest. We had a very smooth process with Golden State and could not be happier with the final product.

We just had our solar installation completed and we are very pleased with the results. Tim and his son were professional from start to finish. They came prepared for our initial meeting and answered our questions in a clear manner. Once we made the decision to go with Golden State Solar, Tim and his son were out within a few days to begin the job. Tim was in constant contact with us about the steps so there were no surprises. They were efficient and tidy and the job was completed in just a few days. I definitely recommend Golden State!

Tim was professional, worked steadily with the planning department for permitting and completed the project within given time schedule. The rewards of our system are clearly seen in the reduction of monthly invoices from PG&E.

Where do I start?! The best thing about Golden State Solar is Tim isn't like other companies who say they are going to show up and don't! He shows up when he say he is going to show up! He installed solar on my roof and I have been extremely happy with the results. Always on time and within the estimated budget. I definitely recommend Tim and Golden State Solar to anyone looking so save money on their electric bill.

I found Tim and Andrew at Golden State Solar recently and had them install solar for my well pump. None of the bigger chains wanted to take on a project that wasn’t cookie cutter. The other guys wouldn’t listen to what I wanted and so I thought I would find a company that actually wanted to do the project. These guys were great. They were reasonable, fair and easy to work with. They did what they said they were going to do when they said they were going to do it and their work was meticulous. I am very picky and I am very satisfied. I would highly recommend them.

I found Tim at TD Construction several years ago and have used him on so many projects. Is there nothing this guy can't do? He is an awesome woodworker and an excellent electrician. I recently had him help me with a couple of home projects. First, I bought a chandelier that was wrong for the application that I bought it for, but Tim came to the rescue and modified it (you could never tell) to work. Yay, cause I love it and didn't want to return it. Then he put in a solar well pump for me. Perfect job, he is always reliable and does what he says he is going to do. And he is reasonable

We initially met Tim to help repair loose wood and dry rot on our outdoor stairs. It just so happened we also needed a handyman to come build a wall in our renovated apartment. Tim definitely came in handy and helped build a wall in our apartment. Not only did he build a wall, he also mentioned other concerns, health and safety issues about the bathroom conditions. These were definitely concerns I had prior to moving in and I am very thankful that Tim did what he had to do to repair our bathroom structure. He is very knowledgeable and able to explain issues where it makes sense to someone like

Tim did a great job on the gas line for our fireplace. We got fabulous service from start to finish. He did everything he said he would and more. He was right on time for the in home quote and the installation. The job was done professionally and no need to clean up after. He left my house as it looked when he came in. He was very knowledgeable about his work and friendly. Fabulous service! Reasonably priced. Very happy with our experience. Couldn't have asked for anything more. Thanks Tim!!!

I have worked with Tim quite a few times now and his service is 2nd to none. Always shows up one time, nicely groomed, and a smile on his face. He cleans up after himself and can fix or build anything I have put at him. Another plus is he is licensed and insured. I also can't believe how reasonable his prices are for such high quality work. Thanks Tim!!!
