Agathon Solar

Each mark is one company we hold in the Grand Rapids area whose Google breakdown has been read, placed by its share of one and two star reviews. Agathon Solar is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

  I asked for a quote for a battery install. See the photos I posted, which will tell the story in pictures. The raw cost of Tesla Battery listed on the Tesla site with every component quoted by Agathon is under $10K. Agathon quoted $38K, meaning they are trying to charge $28K to install. I thought this was a mistake, so I called Greg Oliver, who provided the quote (he says he also owns the company), and he stood by the quote. In his words, "I don't know where you're getting your numbers..." As you can see from the photos, the numbers are from Tesla. If I were you, I would not waste your time wi

  From the initial consolation to the written proposal and the final installation working with Agathon was clear professional and helpful. They were thorough in explaining the process so there were no surprises. The installation work crew was efficient and friendly. Final instructions were clear. I’m glad to contract them and would recommend them without hesitation. They do good work as their name implies.

  My home has been largely powered by solar-generated electricity since 2018, but without a battery backup system. The original solar array on my home was installed by a well-reviewed company in the Detroit area. I utilized the Energy Sage online resource for information and to identify installers at the time.

  As a general rule, I do not review vendors, service providers and contractors (in fact, this may be my first). I contacted Agathon approximately a year and a half ago regarding a potential solar/battery installation. After numerous inquiries, all of which were answers promptly and comprehensively, Agathon installed a twenty-two panel solar system with an integrated battery storage system on my residential home. I have found Agathon’s communication, professionalism and responsiveness to be exceptional, starting on day one. Agathon’s team consulted with me throughout the process, ensuring that I

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

Its website also mentions free estimate and family owned, but not in a sentence we can quote cleanly.

• It is also reviewed on ConsumerAffairs. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
• It posts on LinkedIn, Facebook and X. A page that stopped posting years ago tells you something a listing will not.

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

• —The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
• —We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
• —We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
