DO NOT use Simms Solar. After completing our install in-December 2025, and full payment against the contract, we are still without any solar power. He said at the time he was still waiting authorization from SDG&E to have our system approved before 'going live'. It is now end April and we still have not had the Solar 'approved and connected'. I subsequently made inquiries on the Contractors State Licensing Board (CSLB) website, to learn his license is under suspension. He did not disclose this at anytime, albeit the CSLB states "The licensee is not entitled to operate during the period of suspension until certain requirements are met." On checking with SDGE they have advised that the solar permit application submitted by the contractor had expired. All attempts to get Simms Solar Inc to submit the required permit have failed. I am pursuing his illegal operation with the CSLB. Matt Simms lacks integrity and ethics insofar as his professional behavior and operations. He is not to be trusted. read more

We can tell you that Simms Solar ( Matt Simms) abandoned the project because he had not wired the system properly, he left two seniors with unsafe wiring and walked away. He also cov-ownes ASP Solar buyers beware. Not sure how he sleeps at night. read more

Don't do business with Simms solar. At the very end of our project, we needed to complete the interconnection with SDGE. Matt has not responded to any of my calls or texts to get this done after saying all along that "we're good to go". After calling the county they have no record of any plans submitted which he said he did. Furthermore the inspector noticed many panels install incorrectly as well as other system components. Now I am having to pay another company over $20K to fix his mistakes. We are taking Simms solar to court and moving forward with litigation. Do not do business with Simms solar. read more

Matt Simms from Simms Solar has now abandoned the installation leaving us no option but to go to his bond company and hire a new company to complete the installation do not use this company. read more

Do not use this business there are better options matt has stopped communicating and stopped responding. He Has not finished the project he owes us pannels and has not set up our app through enphase. All previous communication was basicly excuses. I used his buisness because he was a long time friend I should have looked up his buisness first I went on good faith but if you look at his reviews you can see this is not a company or man you want to do buisness with. Be a man matt keep your word!!! read more

Do NOT use Matt Simms/Simms Solar. He "ghosted" us after panel and battery install, didn't finish the final project requirements necessary for passing city inspection, never filed the necessary application with SDGE (which should have been done before install), and never filed the battery rebate application when he went as far as to tell us the application review was in "final stages". Beyond unethical. Took full payment up front. This was back in late 2024 and we JUST got permission to operate. Sadly, I see he is still doing this to others. read more

We hired Matt Simms to install our solar panels back in 2023. It was nothing but a headache since they don't know the local protocols in my city, which I was able to find on the city's website. It took more than 6 months and a lot of calls and emails to get the solar up and running. Fast forward to November 2025, I cannot get my internet to connect to the panels, so I texted Matt Simms for help. He said someone will come out next week Wednesday. Wednesday came and went, no one came out, so I texted him again. He said he will come out himself the following day. The next day came and went. Now he's not responding to my text messages. Stay away from this company! I will not use the again for any of my other properties for future solar projects. read more

We recently hired Simms to do a solar install project on our home and it has NOT gone anywhere close to planned. We signed the contract in early August 2022 and the panels were installed in late September. The panels were NOT installed per the agreed upon site plan and two of the panels are severely shaded by the other installed panels and producing about 50% of the other panels. However, that's the least of the issues we're facing. They installed the panels before officially getting the city permit and after many weeks of saying they were waiting on the city, I contacted the city and found out that the permit was never submitted. Upon confronting Simms with this info, they then submitted the permit in late December and it failed permit review. They never corrected the permit submission and have now ghosted us. They no longer return calls or emails. So the current state is an unpermitted install not to plan with NEM 3.0 coming very soon with potentially large financial implications. They've left us high and dry with no clear path on completing the project in time for NEM 3.0. There are more trustworthy solar companies to do business with so look elsewhere. read more

Matt came highly recommended by two separate coworkers that both got their systems installed by him. I have been wanting to install solar for several years so far but unfortunately had some personal matters to take care with the home before beginning to make upgrades. But I saw the writing on the wall, the tax credit for solar is going to be reduced in 2020 and the utility companies are going to push for even more restrictions when Net Metering 3.0 comes out within the next year or so, I knew I had to act now to make solar even more worthwhile. I contacted Matt via phone and to get a estimate, all he needed was recent SDGE bill in order to figure out my usage and what size system I needed. He got back to me within an hour or so with both a purchase price and a financing price. The estimate clearly laid out total price, where the panels would be placed on my roof, interest rates and the estimated savings I would receive over 25 years (the typical life of most panels). That's pretty good for a contractor, most struggle to get you full estimates quickly or want to waste your time chitchatting about how good their company is, but Matt got straight to the point which is awesome. Since the panels last for 25 years or so and my roof was original since I moved in over a decade ago, I thought it was a good idea to get it replaced. Matt was able to get some roofers to look at my house and give me a estimate within the same week. I took their estimate and went to another coworkers friend who does roofs and got the process going. Even though I didn't use Matt's roofer, he was very patient in the process of waiting for it to get replaced. The very next week after my roof was done, the system was installed and it looks beautiful. The pipe run looks clean, install overall looks very professional. Matt did all the necessary work of submitting plans, pulling permits and making the process go smoothly with the city and power comapny. My system got turned on and now my panels are making me power. The meter spins backwards for the majority of the daylight hours no matter how much stuff I got running in the house, which means no more overage charges. I'd love to say that I went solar to help the planet, which is great and all. But the main reason is because SDG&E is the worst. Everything they've done is to overcharge San Diego residents for power, we pay more for electricity than almost anyone else.  I'm glad to know that I won't be getting screwed every summer when I turn on my AC. I'd like to thank Matt for the professional install and I would gladly recommend his company to anyone for their solar needs. read more

Simms Solar - Professional install, looks very clean. Pipe run isn't super visible either. - Solar Installation Near Me

Matt is the guy for solar if you live in Ramona. Super professional and 100% honest, which is extremely rare to find in this industry. We had Enver Solar install our system, big mistake. They offered a lifetime warranty but are out of business and won't answer our calls. What a nightmare. Matt Simms was recommended to us by a friend in Ramona. What a relief to hear a solar guy someone actually recommends. Well now we know why. Matt came to our house to do a checkup on our system and everything works fine now. He gave me a great education inside and outside of my home. Several times he had the opportunity to try to sell me something but he never took advantage. I was really floored by how honest Matt was. It's just so rare in this industry. Safe to say he's my new solar guy now. If you live in Ramona or near Ramona you're lucky to read this review. We highly recommend Simms Solar which is rare for us to recommend any contractor yet alone a solar company. If you have any issues with them you can contact me directly! hah that's how much I trust these guys. 5-Star Solar Operation for sure. read more

Simms Solar are my go-to solar guys. First they did my home and the whole process was smooth, fast & easy. Every single person I came in contact with was professional and polite.

I am a Realtor and a Property Manager so I have misc. questions and jobs for Matt every so often. No matter what the situation, he is happy to step in and help me. He has saved me on a couple of solar jobs that he didn't even install. His knowledge and professionalism is an asset in this industry and I highly recommend him and his company. read more

I can't say enough good things about Matt Simms and Simms solar. They are so knowledgeable about solar panels. They installed a ground mount system at my house. Their pricing was the best (by far) of all the bidders. Now that the panels are in operation, the savings that were forecast are right on the estimates! I couldn't be happier.

Was very against the salesy solar people I had met previously - then we met Matt and his team... they give you the bid and let you decide! Super easy to work with and very accommodating- I would HIGHLY recommend! read more

Easily the best value on the market. I researched various other companies and was not able to find anyone that even came close to their price. The owner, Matt, seemed like he really cared about doing a great job in a professional manner. He was extremely knowledgeable when it came to answering my questions and believe me, I had a lot of questions. I really appreciated how careful they were in making a clean installation without harming my home or yard. I could not be more satisfied with my new solar system. Even my brother, who works in the solar business, could not believe the deal I was getting for such a great system. read more

I went with Matt Simms after researching my options in San Diego for solar panels. My previous home solar company wanted to force a sell on my panels after only one month of living in this new home. Matt is more about providing quality service with an honest approach rather than making a business transaction. His team was very professional and completed the project with cleanliness and had complete reassurance that I had the best company working with me. I HIGHLY recommend Simms Solar for solar and home battery systems. read more

Matt the owner is great. He will not pressure you into buying solar, rather he will sit down with you and your electricity bill, his quote and tell you your options. Then it is up to you. The day of install his guys showed up and in one day my solar was on the roof. Our biggest SDGE bill since then was in winter and we paid $13. After the install, he has been available with any questions I may have. (Yes the owner of the company answers his phone and assists you with questions) It's been great. If i could, I'd give him 37 stars. But not 38. ;) read more

Simms Solar - Solar Installation Near Me

When his employee was unable to come to my house for an inspection of current solar system, not installed by his company, owner Matt Simms drove all the way from Ramona to Oceanside for about a 20-30 minute job. He was professional, courteous, and was a tremendous help pointing out shoddy work and trouble spots. I wish I knew about Matt's company before I installed my system. Any and all future solar work will be done with him. Thanks again Matt! read more

Simms Solar did an outstanding job on my house. I've had my system running for about a year and have seen no issues. Matt was very professional and NOT pushy. He walked us through every step of the process and answered questions that we had (if you know me, you know I ask a lot of questions). I recommended contacting Simms Solar and discussing your options. I'm saving over $100 a month on averge. Hope this helps if you considering Simms Solar. read more

The owner, Matt Simms, was our lead contact throughout the project and was always responsive to questions throughout the project. It was a pretty big job since we also were having a new roof installed at the same time. Simms Solar worked hand-in-hand with the roofers so that there were no down times. Both projects were done on time with the schedule we were promised at the outset. I waited one year to write this review because I wanted to verify that the bottom line cost to us was what was promised. We just received our 1 year "True Up" statement. In a year that we used our AC and heater more than normal, we ended up with a $200 credit with our utility company! Bottom line was that there were no 'negative surprises' in getting the solar system. I give Simms Solar my highest recommendation as they were great during the bidding, installing, follow up questions, and the results were as promised. Its also nice having the owner be the contact person as Matt has a strong incentive to perform as promised. We were given a recommendation by friends for Simms Solar when we were bidding the job out and now are happy to do the same for Matt Simms going forward. read more

So glad we went with Simms Solar. Great customer service, no pressure, and weve had no problems or issues. Recommend them to anyone.

Wonderful solar company. Matt Simms came out and looked at our older system which we wanted replaced with newer more efficient panels. They were here on time and the work was done quickly and efficiently. Excellent job, great guys. Have recommended them to a few friends already. Reasonably priced too. read more

Simms Solar came out and installed solar on my house and they were the best. The whole process was easy and the crew was pretty cool. I've recommended them to my mom and my friend at woek. I love not having to pay SDG&E!! read more

I was so incredibly happy that we decided to go with Simms Solar. They came out and gave me a bid at the end of March and worked around our busy schedule to find a time to do the installation. The installation was a lot quicker than I thought it was going to be and the guys that did the work were incredibly nice. My neighbors are old and are very uptight about noise and I mentioned that to the owner and he and his crew went above and beyond to accommodate that. They were the cheapest bid we got and I could not imagine how anyone else could possibly do a better job. I cant wait for summer to come so we can run our AC guilt free! Thanks so much Simms Solar!!! read more

Simms solar came and installed panels on my house last weekend and they a great job!! They came early in the morning and worked all day and we barely even knew they were there. The panels look great and the owner Matt was there the whole time over-seeing the project. I wish yelp had a 10 star option, because that's how good these guys were!!! read more

I have been kicking around the idea of getting solar for awhile now. It's a tough time we are living in and let's face it....... every penny counts. I decided to call a couple companies to see what it was all about. Mostly whether it was beneficial or not. After the third company coming out, I just was getting more and more turned away from the idea of getting solar. The sales pitches, the haggle, the lies, and on and on..... I decided to call one more guy.... A highly recommended local company Simms Solar. Matt responded to me promptly and came over the same day to size up and price the perfect system for me. There was no haggle..... There was no lies...... There was no pressure..... I found my company. Upon signing contracts, Matt was out within the following week and did his install in a short and very clean manner. I was so impressed. Now I'm not one to give shout outs or gloat but I feel that he deserves it. I highly recommend Simms Solar. You did a great job!!! read more

Simms Solar - Solar Installation Near Me

Recently had Simms Solar install some additional panels to my existent solar roof array. Met with Matt Simms first and he went over several different options with me then he answered several questions I had regarding the job. Matt is incredibly knowledgeable and his team did a super job. I actually contacted several other companies to provide me with additional bids but most of them weren't interested because the job wasn't big enough for them. Matt had no qualms about helping me with this smaller job. I wouldn't hesitate recommending Simms Solar for any solar job you have. He went out of his way to accommodate me regarding scheduling and I couldn't be happier with the job that was done. Great company to deal with. read more

Great Customer Service! Went to 3 other companies before going to Simms Solar. Matt can get it done quicker and worth less headache than the others. The other companies said 2 to 3 weeks for inspection, Simms had me up and running 4 days after installation. The technician Casey was awesome and did his best not to interrupt us while installing the panels. read more
