0/10 DO NOT RECOMMEND This company has honestly given me such a run around. If you get panels make sure to mention you want critter guard.. the 1k up front will save you SO MUCH $$ and time... they of course never mentioned it as an option.. when we had an issue... like OCTOBER- they came out decided it was not their fault (which took a month I might add) - then I said that I would at least like to hear you are going to offer it to new customers so they don't have this issue of never hearing about these problems the person on the phone said "we dont get any incentive in telling you or installing it so we really dont have to mention it." This is 2 years after install.. we will still owe pretty much the whole balance.. honestly this move has caused more problems then it has been worth... do your research and do yourself a favor... find a better company.. a manage would never call me back.. just pawned the conversation off to other employees. Not a great company at all.. BTW - its February and the roof is STILL NOT FIXED

We originally signed with another solar company and quickly realized something didn’t feel right. Promises were made about “American-made equipment,” but after doing our own research, we discovered the inverters were being sourced overseas from Alibaba. That was a huge red flag. We also learned the company didn’t even hold their own contractor’s license and was subcontracting the entire install. It felt like commissions were being prioritized over our long-term investment and peace of mind. That’s when we connected with Michael Shafer at ION Solar — and everything changed. Michael helped us cancel the predatory contract, walked us through every detail transparently, and made sure we fully understood what we were getting. No pressure. No gimmicks. Just straight answers and education. ION Solar completed the entire installation in-house, which gave us tremendous confidence in the quality and accountability of the work. The professionalism, communication, and attention to detail were on another level. If you’re considering solar, do yourself a favor and talk to Michael first. He genuinely cares about doing what’s right for the customer and making sure you’re protected long term. We now have peace of mind knowing we chose one of the best solar companies in the area — and in the nation. Highly recommend.

I was initially impressed with the sales pitch, reviews, and early follow-up (August 2025). However, as weeks, then months went buy, customer service became a repeating horror movie. The sales rep assigned to me blocked my telephone number and left ION. I was not provided with a dedicated contact person to handle the poor communication between customer service, inspections, construction, financing, etc. Scheduled appointments turned to no shows, where I took off from work to be available. Or, workers showed up before the scheduled appointment, and I had to leave work to meet them because to reschedule could take weeks. Finally, in late November the system passed inspection and was supposed to be up and running. Now, 12/17/25 I'm waiting for the communications between the panels and the separate monitoring company to be fixed. Also, I'm unable to download the monitoring app and cannot get help with that. The operations manager has yet to return my calls; nor can I get anyone to follow-up. I'm now stuck with a $32,000 financing agreement that begins 01/01/2026 for something that doesn't work. This is, by far, the largest and most costly mistake I've ever made. ION is bullshit. My advice---do not waste your time, health, and money on ION. The company is not worth one star.

Frequently Asked Questions

What does ION Solar check during a home assessment?

It measures the roof, tests the service panel, and assesses the roof and attic’s quality and strength.

How soon does installation happen after permits are approved?

Installation typically happens within one day after permits are approved.

Can weather affect solar production?

Poor weather may temporarily reduce production, and snow covering the panels can also affect output.
