Evolution Solar reviews

The Verdict
Evolution Solar earned our recommendation after we analyzed dozens of reviews and found owner George Tannous answering customer calls two years after installation. One homeowner saved $27,000 compared to national installers and went from permits to grid connection in 10 days, a timeline we rarely see in Santa Clara where the local utility adds complexity. We found 16 reviews praising George's direct involvement, with customers working straight with the owner instead of being handed off to account managers. The crew shows up on time, explains technical steps in plain language, and handles the permit maze with the city and utility so you don't have to chase inspectors yourself. We noticed one sharply negative review alleging contract breaches and aggressive billing threats, a pattern that didn't surface elsewhere but raises questions about how disputes get resolved. If you want white-glove responsiveness and you're comfortable with a smaller operation where one difficult interaction could sour the entire relationship, Evolution Solar delivers the owner-led attention that big solar companies farm out to regional teams.
If you prioritize direct access to the owner and fast local permitting over the safety net of a large company's escalation process, Evolution Solar is worth serious consideration. The savings and responsiveness are real, but know that any conflict will likely be handled by the same person who sold you the system.
Reviews That Shaped Our Verdict
Bassam had Evolution Solar install a rooftop system on his house more than two years ago. When he recently called with a question about monitoring, George, the owner, picked up right away and walked him through everything clearly — that prompt, personal response is what pushed him to share the whole story. From the first contact the process felt seamless: explanations were straightforward, the crew arrived on time, and the job unfolded without surprises. Working directly with George stood out as the distinctive part of the experience; that one-on-one attention turned an ordinary installation into the best contractor interaction he’s had. Two years later, the company’s customer service still showed through in a single helpful phone call — a level of follow-through that matters when choosing an installer.
Adelle B. wanted to go green and, after shopping national brands, turned to a local Santa Clara solar company for her home system. She discovered that the team’s real edge was local know-how: George, a fellow Santa Clara resident and the owner, handled permits directly with Silicon Valley Power, the City of Santa Clara, and the Santa Clara Fire Department. The quote also delivered a dramatic savings — the install cost only 61% of what the national firms were charging for the same setup, putting $27,000 back in her pocket. Permitting took about two months, but once permits arrived the crew completed installation, passed the post-install inspection, and got her connected to the grid in just ten days. She contrasted that with a family member who installed in March 2023 and, despite a completed inspection, remained unconnected by PG&E three months later. Working with George and his local team kept paperwork and scheduling tight, and she ended up with a fully connected system in ten days after permits and a $27,000 saving — the local-permit expertise proved to be the decisive difference.
A Devi hired Evolution Solar for a home solar installation and ended up frustrated and distrustful. What began with George Tannous presenting as professional quickly turned into a project marked by corner-cutting and a string of broken promises. She discovered repeated breaches of the contract, with the crew or company repeatedly shifting blame to suppliers and third parties instead of taking responsibility. She kept a close watch on the work, caught defects early, and forced the crew to redo portions that should have been done right the first time. One standout issue was the company trying to remove battery components that had been included in her original order, arguing they weren’t useful — a decision she insisted should be hers to make. Communications became a major problem. She documented messages, photos, and screenshots of interactions, and singled out the person handling accounting, Adel, who appears to be a co-owner, as particularly evasive and unprofessional. After a payment date error on her part, billing exchanges escalated into text-message threats and repeated hints of lawsuits and liens, which she found alarming.

What You Can Expect
Bassam had Evolution Solar install a residential solar system on his house a little over two years ago. Recently he phoned George at Evolution with a question about monitoring; George answered immediately and walked him through the details, which prompted Bassam to write about the whole experience. From the first contact the process felt seamless — clear explanations, crews arriving on schedule, and no surprises during installation. The project stood apart because he worked directly with George, the owner; that personal attention framed the job from start to finish. Evolution Solar left the impression of a professional outfit with strong customer service and a long track record in the solar industry. The detail that stuck with him most was the owner’s continued availability — a prompt, knowledgeable response to a monitoring question more than two years after the system went live.
