Reviews

One homeowner praised a smooth installation and said the system eliminated the electricity bill. Three customers described door-to-door visits; two said they had no-solicitation signs. Another customer reported that installation took months because parts were missing and warranty repairs came with extra charges.

Customer Reviews

Supreme

Their salesman came to the door and I have signs saying no solicitation and they tell you we’re not selling anything then proceed to try to sell u solar. Then they get upset and speed off in the neighborhood where there are kids present.

Mike Davies

Absolutely the worst purchase I've ever made. Far too expensive and they don't fix items under warranty without charging even more. The install process took months because they don't have all the parts needed and don't remember to come back. I highly recommend to not spend a cent on their product. All their warranties are lies to scam you into buying. Nothing is free.

I have no solicitation sign and yet they still rang the doorbell and knocked on my door. They would start by saying has Excel energy contacted you? Then saying this is not a yes or no answer, excel is moving to clean energy then he proceeds with selling solar energy. Seriously!!! What a tactic, and he proceeded with I’ll come back next time it looks like not a good timing after I said I’m not interested. You’re not Excel energy so stop using their name so you can talk to homeowners and sell your product!

Jackson Hamm

Highly recommend this solar company! From start to finish, the experience was great. The team was professional, easy to talk to, and super helpful with all my questions. They made the whole process smooth and straightforward, from the first visit to the final installation. The solar system completely eliminated my electricity bill, which has been amazing. If you’re thinking about going solar, definitely go with this company. They’re reliable, efficient, and really focused on doing things right. Even the guy who knocked on my door was respectful, kind, and took the time to understand my situation. That meant a lot.

Came to my door twice so I interrupted a work meeting to answer. They are either unable to read or they have zero respect. I have this sign right outside my front door and I don’t know how to make it any clearer that I don’t want to be bothered. The guy ended his pitch with “we will stop by next time we’re in the area.” No. Do not. I’m not interested. FYI TO ANYONE WITH A SIMILAR EXPERIENCE Many cities in Colorado require door-to-door solicitors to have a permit/license, and to respect “no soliciting” signs. I encourage you to contact your city and report them. You can also leave feedback and a complaint with the BBB. You can also report deceptive business practices and violations of the Colorado Privacy Act (such as requiring that you provide additional information to get on their “no knock” list) to the Colorado Attorney General through their website. RESPONSE: Giving people extra work instead of following the law and respecting their no soliciting signs is unacceptable. I don’t have time to contact every solicitor to provide additional personal information so that I can be left alone, that’s why I put the sign up.

Frequently Asked Questions

How long does ION Solar's installation take after permits are approved?

ION says installation typically happens within one day after permits are approved.

Will ION Solar customers still receive a utility bill?

Yes. ION says customers still receive a monthly utility bill; a small grid-connection fee is typical, and additional fees depend on electricity use and system production.
