Overall a very good experience. George was knowledgeable and forthcoming. I felt comfortable throughout the whole process. George took care of all the complicated details of the installation and subsequent inspections. His installers were respectful and professional. I highly recommend this company.

Beware of Evolution Solar – Dishonest and Untrustworthy

I wish I could give zero stars. My experience with Evolution Solar has been extremely disappointing.

Initially, George Tannous came across as professional, but that quickly changed once the project began. It became clear that corner-cutting was part of their process. Throughout the project, I encountered numerous misleading statements—not just from George, but seemingly reflective of how the company operates overall.

The positive reviews they have online are hard to believe after my experience. I’ve documented messages and interactions that speak volumes about how they conduct business. The person handling their accounting, who appears to be a co-owner, was particularly difficult to deal with—unprofessional and evasive, especially when issues arose.

They breached the contract multiple times, frequently shifting blame to suppliers or other third parties instead of taking responsibility. Thankfully, I identified problems early on and kept a close watch on the project. Because of that, they had to redo parts of the job, which likely cost them more—but it shouldn’t have been necessary in the first place.

They even tried to remove battery parts that was included in my original order, claiming it wasn’t useful. That decision should be mine, not theirs.

I’ve also posted a detailed review on Yelp with photos and screenshots to warn others. Be very cautious if you’re considering working with Evolution Solar. In my experience, this company is not trustworthy and does not operate with integrity.

I made a payment date error and see for yourselves, his text message threats, this has been the entire experience. The Adel person in accounting, I bet he has not accounting degree or experience, I see it in his billing and money hungry and no customer service, everything ends with a lawsuit or lien threat.

I am thrilled with the services I received from Evolution Solar! I had contacted Evolution Solar to inquire about a solar system for my house due to a referral from a friend who used their solar system installation services a couple years ago under NEM 2. My friend was very pleased with the process with the company and strongly recommended that I contacted them. And what a recommendation it was! I did not know much about solar systems, but I had heard about the change of regulations from NEM 2 to NEM 3. I was surprised that the owner & CEO of the company, George, answered my call and had a great and informative conversation with me about the options and the most economical system configuration for my house based on my consumption. The whole process went very smoothly.
Evolution never oversold the system and provided the best option for my specific case with the solar panels and battery system. The whole process from my call until the installation and Permission to Operate from PG&E took about 5 weeks.

The system looks great and works perfectly. I have called them several times after the installations to ask questions about monitoring the system and every time I called, they clearly explained the monitoring and answered all my questions. I highly recommend Evolution solar without reservations. It was absolutely the best experience I have ever had with any contractor! Thank you George and company!

Evolution Solar installed a solar system on our house over 2 years ago. I just called Evolution Solar (George) for questions about monitoring. George immediately answered the call and explained everything very clearly, so I decided to write the review about our experience from the day we contacted Evolution Solar:
We appreciated how seamless the process was with Evolution Solar. Everything
was explained clearly, the team showed up on time, and there were no surprises. Best of all, we worked directly with George, the owner. That personal attention made all the difference. It was the best experience I have ever had with any contractor. Evolution
Solar is a professional company with excellent customer service and long history in the solar industry.

My experience with Evolution Solar exceeded my expectations in all manners. I spoke to George directly during my first call, and he stayed in touch with me through every stage. His knowledge and patience really stood out, he explained the pros and cons of different panel options and batteries, helped me understand the payback timeline, and never once rushed me.

Once I gave the green light, the process moved quickly. Their crew was punctual and respectful, taking extra care to minimize any disruption. You can tell they take pride in their work. George even stopped by 3 weeks after the install to make sure everything was functioning properly. That level of follow-through is rare. I wouldn’t hesitate to work with Evolution Solar again!
