We decided to put Solar on our home and contacted five different solar companies. One of the…read morecompanies was from the bay Area, they presented the SUNPOWER solar panel to us and after doing the homework, we decided to go with SUNPOWER Solar Panels because they are the best of the best. The bay area company submitted a bid for our system. We contacted Alternative Energy Systems in Chico, as they install only SUNPOWER Solar Panels., we requested a bid from them "Apples to Apples", for the SUNPOWER Solar Panels. The bid came back totaling more than 15% LOWER than the bid from the bay area company. We signed a contract, and the installation process was unbelievably smooth, they took care of everything from start to finish. The installation crews we're professional, knowledgeable, considerate and friendly. They have the highest qualified electricians working for them, ensuring only the best for their clients. Always checking with us and explaining any concerns that we had. This was an enjoyable experience for us and there is no doubt that we have chosen The Best Solar Company in California for our installation. Alternative Energy Systems.

There are never any hard sell tactics or pressure into getting things we don't need and can't afford. Never! I like how the company keeps a written record of the make/model of the units and detailed notes & checklist on maintenance & repairs. A paper copy of this is provided at the time of service for our file. There is no question about the history of the unit and its possible needs in the future. We have joined the Maintenance Club for $149/year which gives us heating & air maintenance every six months. With an older house such as ours, this brings us peace of mind. We highly recommend Climate & Energy Solutions.

We have had a great experience with Ohm Solar Solutions in Chico. We found out about this Company…read moreat the recommendation of our roofing contractor. We had a solar installation that needed to be removed in order to complete the re-roofing. We contacted the original installer of the solar panels to handle the removal, but needed to send a letter to them because it is impossible to reach anyone with that business by phone or email. They never gave out a phone number for texts and were extremely frustrating to work with initially. They came out, said the 3 roofing contractors who told us the solar installation was done incorrectly were wrong, promised to send an estimate to remove and reinstall, took down my email address, and we never heard from them again. Our roofing contractor worked with Ohm Solar Solutions to remove and reinstall the existing solar installation. Brandon was our Ohm sales representative. He called back to make an appointment the same day that I called to inquire about installing additional panels. At the last minute, we decided to also get a battery. The prices were fair, based on the current market and the impact of tariffs. Ethan, their case manager, was assigned to us. He responded within minutes to my text messages or phone calls. When they schedule a time to come out, they arrived or let me know there would be a delay. I can still text Ethan if I have questions and continue to receive excellent service from Ohm Solar Solutions. Everything is up and running. They assisted with apps that keep us informed about the power being generated and how it would be distributed. We are still connected to the grid with PG&E, which is needed if we have a series of cloudy days, but PG&E is also purchasing excess power generated by our system. We could not be happier! What a contrast to our experience with the other solar business!!

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.

Workers came out and worked on my system three times never talking to me just leaving door hangers saying the came out. 2. They designed a system to meet only 80% of my needs why on earth would I want that ? They shorted the panels I needed and I would've paid for and thought I was paying fir a system that would zero out my PG&E bill . 3. My annual True up has been running $3500.00 4. They owe me 12k the difference between the financed price vs the cash price since 2017 the one year anniversary of the system I got in March 2016 . * Because I thought the two sales guys where very knowledgeable and helpful , friendly. I told them to add $500 for them to split. Thus the financed price was to be 39,000 plus the $500 totaling $39,500 which I paid thinking I would get the cash difference once the Hero program informed them it was paid in full . The county refunded their Hero set up fees around $3000.00

First of all, in June of 2025, they replaced the coil in our air unit and supposedly fixed a Freon…read moreleak, and....charged $75.00 to travel from Chico to Corning, 20 miles. $1900 later our air conditioner worked. Less than a year later, March 2026 we are having hot weather and the air stops working, the 'new' coil has froze up again. Called them to fix it thinking that they should have guaranteed their work from 9 months ago. They came out 4 hrs after they said they were on their way. Once again they said we had a small Freon leak and fixed it...again. They leave and we are thinking all is good. 5 days later we receive a bill, in an email, for $410 to once again fix the 'small' Freon leak that they had 'fixed' 9 months before. I will NEVER use this company again, nor will I recommend them to anyone. Now Giuseppe is responding with excuses, as usual, as to why there is a problem with their service. First off, he tries to say that this was an old unit. Not true! The inside unit is 15 years old and the outside unit is 15 years old. Both installed new when we purchased the house. He has no idea how old our units are as he has NEVER been to our house. They replaced the coil 9 months ago, because of a leak, according to him, yet 9 months later this NEW coil has a leak. Hmmmm, maybe he installed an OLD unit and charged us $1900.00 for it. If you notice the response that he has for other negative reviews, it is always an excuse and someone else's problem. He cannot take responsibility for anything as far as I can see.
