Simms Solar, Inc. review

Positive reviews:

“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.” – Jacques R. ⭐⭐⭐⭐⭐ June 10, 2021

“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. The equipment was installed super clean and aesthetically pleasing. After this experience I continued to call on Matt for other solar & electrical needs. 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.” – Rachael C. ⭐⭐⭐⭐⭐ November 23, 2021

Negative reviews:

“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.” – Graham E. ⭐☆☆☆☆ April 29, 2026

“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.” – Tyler P. ⭐☆☆☆☆ November 22, 2025
