On top of that, they're just good down-to-earth people. We hired them last spring to re-roof our home, replace some rotted eaves and fascia and replace our old solar system (it was inefficient and malfunctioned quite a bit). We are very happy with what we got for the price we paid, it was a good value. It looks so much better than it did before and is consistently producing more energy. I feel like they helped us make the right decisions through the whole process, especially for system size to be able to keep our NEM1 status. The new roof looks great and works really well. I waited almost a year to write this review to make sure there wasn't any water intrusion during the winter storms - not a drop anywhere. They were in the mid-high range in pricing on the bids we got, but I'm happy we spent a little more went with them. Can a roof be sexy? Ours sure is. All in all, if you need a new roof or solar system or home battery, or all of the above, call Volt. They are a competent and professional group of local people who are really f**king good at what they do.

The new system eliminates our PG&E bill, totally offsetting our yearly power consumption from our well pump and swimming pool.

Their electrician also did very nice work, integrating the conduit, wiring, and boxes in a seamless and clean professional install. A few months in, the system is cranking out the power.

The only downside was that my furnace is in the crawlspace above my laundry room they had to remove the trim and some drywall to get the new unit in there. I would have liked to know that in advance (that the new unit was larger than the space opening could accommodate) because their quote to repair the drywall and trim work was way more than I was willing to pay, so I found a Handyman that would do the work for much less money. Bottom line, they did a great job and I was happy with the overall work. I would just make sure to ask them if the new unit will fit into the space that you have available. Just so that you don't get a surprise extra expense.

I would have given them a 5 star review if not for two disappointments given at the bottom…read more I went with Chico Solar Works because they could also replace the roof (Chico Roofing Company) and I was willing to pay a premium to have a single company to deal with if anything went wrong. Also, they have been around for quite a while, I knew a few people who had used them for solar and their prices weren't out of the ballpark. Once the installation began it went quickly and smoothly, taking only a couple of days for installation and PG&E approved the installation within a few days. Note that they also had to upgrade our breaker box to 200A and they did a great job of matching the adobe texture and paint color where they had to cut out for the larger box. There were two things that were a bit disappointing. One was that the monitoring app showed incorrect "Consumed" energy information. It was including the produced power so when the sun came up my Consumed power went up at the same time as the produced power from the panels went up. According to Enphase this is a rather common issue and yet it took a couple of weeks to get Chico Solar to recognize there was a problem, which included my talking to Enphase a couple of times. Even after it was agreed there was a problem it took another month to get the issue resolved. It was disappointing that the people who do the installations couldn't recognize there was an issue even when I described it to them. The second issue is that (at least) one of the panels has a scratch a couple of inches long. At least initially this is not going to be an issue but I suppose it could lead to early failure. I have not reported that to Chico Solar. I should also mention that all the installed equipment was as quoted except for the panels. The panels were from a different supplier and had an additional 10W output with nearly the same specs otherwise.

They designed a system to meet only 80% of my needs why on earth would I want that ?

I told them to add $500 for them to split.

I spent about three years shopping for a solar energy system. I received quotes from a few vendors…read moreand spent countless hours reading on the Internet. I was very concerned about warranty issues and also about how the installation would affect my S-tile roof. One company misled me about their warranty coverage (I found out by reading the fine print) and another failed to give me a copy of their warranty after three requests. There were a few quirks to my installation that would require some creativity and care, and I was not encouraged by the lack of accurate information or personalized attention I received from these other vendors. I thought perhaps I would not ever have solar on my house. Based mostly on Yelp reviews, I decided to contact United Sun Energy. The first call I received back was from Phillip Egan himself. Subsequently, I found everyone involved to be professional, helpful, and friendly. Shawn is an easy to talk to no-pressure sales / coordinator. He showed me some new hardware that they use for S-tile roof installations that no-one else had mentioned. The office staff is pleasant and efficient. They have experienced solar experts handling design and installation issues. When the unique circumstances of my house and my requirements came into play, my request for a detailed plan was answered with a visit to my house by their project designer and by Mr. Egan. They crafted an excellent solution on the spot. They were patient and cheerfully re-wrote the proposed contract (which is detailed and in plain language) as I changed my mind a few times regarding some of the equipment to be installed. Theirs is the only contract among the vendors that I contacted that specifically warrants against damage to your roof. A quiet and very polite crew came to the house to install the panels. They were extremely careful during the installation, and left my roof and property in better condition than when they arrived. Ryan came next, and installed the electrical system. He is a craftsman and and gentleman and did a superlative job. I cannot say enough about what a great job he did. The system has been in place for about three months, and is working perfectly - exactly as promised. It took a long time to find the right team to install my system, but I am glad I was patient and diligent. The whole process, which I feared would be an ordeal, was extremely easy and pleasant. The cost was exactly as promised in the contract, with no surprises. I wholeheartedly recommend this company if you are considering solar.

But what caught my attention at first, was that instead of focusing on selling us anything, our salesperson simply tried to educate us on the options and the system itself. Everything was put into simple, logical terms - especially the financial end of it. I felt like we finally got to the point that we could truly make an informed decision. It turned out that there were a couple of good choices, but United Sun Energy also happened to give us the best value. They were one of the 2 lowest bids and they had the most complete warranty, plus lots of experience. It's now been a little over a year since we installed our system and we have been just as happy with our system after their installation as we were confident when we made the decision.
