Intermountain Wind and Solar

Poor Communication.

I have been less than satisfied with the service provided by Intermountain Wind and Solar. The lack of communication throughout the permitting, installation, and inspection process was very frustrating. Had I not been diligent about calling regularly, I believe this project could have been delayed by another three months. It was not that I expected weekly calls, but when milestones should have been met, there were no calls or emails to explain what was happening. For example, it took 20 days from the time my engineering design was completed by IMWS for it to be submitted to the city/county. On September 3, I was told the project package was ready for permitting and that the municipality typically takes about a week to approve and issue permits. However, IMWS did not submit for permits until September 20, a delay of 17 calendar days, or about 2.5 business weeks. Delays continued at nearly every stage of the project. The system was installed on November 19. It then took another two weeks before the Tesla battery was provisioned. Four weeks later, the critter guards were finally trimmed to satisfy the city inspection requirements. After that, there was no contact until April. I just received my ownership documents on April 1, 2026, five months after the project started and about 3.5 months after installation. There were also many instances where I called and emailed without receiving a response. I was never clearly told which email addresses to use to contact support or my project manager. The customer service was extremely poor. When I expressed my frustration about the lack of communication, they implied it was my fault for not emailing the correct addresses, even though the employee I had been contacting had left the company two months earlier. There was no way for me to know that. Project timeline: August 23 – Project signed and initiated September 3 – IMWS engineering package completed and ready for permit submission September 20 – Submitted for permits after a 17-day delay October 6 – Permits approved October 20 – Rocky Mountain Power net meter approved October 22 – Installation scheduled November 19 – Installation completed; inspection still needed and critter guards needed trimming November 29 – 10-day delay; installers failed to install a required placard. IMWS mailed one to me, and I had to install it myself and send photos December 2 – 13-day delay after installation; project sent to power company for inspection December 8 – I called because I had not received a response about the placard, and they had no record of my email December 11 – I emailed because the critter guards still had not been trimmed December 15 – Project marked complete and all punch-list items finished Overall, the biggest issue was not just the delays, but the lack of proactive communication and the poor customer service throughout the process.

Good Product Poor Follow-up

I chose IMWS because the product was highly rated and the sales people seemed to know what they were doing. The product is fine and was installed correctly. It just took forever for the installation to happen. My sales rep left the company and the district manager didn't seem to have enough time to make sure my order was properly prioritize. Any service comes from Utah. I've had problems with the reporting system continually dropping my internet signal. I emailed the district manager after having no response from the service guys. Finally one service guy called back and we were able to resolve the issue. The service manager never responded.

Fine except for one issue

They were the most professional when I got assessments, all those years ago.

Sales was helpful

Sales rep was helpful. Install crew didn't seem to agree with some of the install plans, the team wouldn't install equipment on first date scheduled. Came back a couple weeks later on next available date, went ahead with original plan. Sales rep was unavailable during install, and since the two departments didnt communicate well, it caused issues. Sales cycle seemed long, 6 months plus, almost all of it was waiting on IWS, the city and HOA approvals just took a couple days to schedule and complete. IWS electricians, architect, and install crews were usually the bottle neck. I don't think their price was much better or worse than other options. And they don't provide financing. Havent needed much support after install two years ago, so we're pleased with that.

Off-grid Super Performer

My small off-grid solar electric self-installed system needed repairs which were handled professionally and efficiently with excellent equipment and performs without a glitch for five years now. However, I tried to contact IWS for an additional system upgrade last year and could not get them to respond to email or phone requests. I had to go elsewhere. Am I too rural? Am I too small?

Do Your Research

They send a sales person to "sell" you the system. They make promises and non-stop calls after the visit to get you to buy the system. Over 2 years after having my solar system installed, I've never banked enough credits to have year round "no-payments" to Rocky Mountain Power. This is a big sell point, and it just didn't happen. Makes the pay back time for the system quite a bit longer. I'm disappointed that I did not research the right system on my own to get it right, because IWS did not get it right for me!

It took to long to get it installed

I signed the contract on Sept 14 was told it would be installed in 4 to 6 weeks, 13 1/2 weeks later we got to turn on our solar panels. It took from Sept 14th to November 12th to get started on the installation, then from Nov 12th to Dec 17 to finish the project. You would think with a company this large that this would be a no brainier as to how long each step takes, but it seems that the next step was not even thought of until the first step was finished. Your communications need work, I had to send emails to find out what was going on. And the sad thing is I dont remember ever getting a response to MY email, I would get information about 4 or 5 days later. The salesman was AWESOME he bent over backwards for us, but he is not in charge of installation. When someone pays $20,000.00 for a product you would think they would let you know what was going on almost weekly. We are excited to see if our investment is going to pay off as promised.

They tried

I was disappointed that I wasn't allowed more input, planning and designing MY system. I have had a lot of training in solar and told the sales person that I wanted to be involved. I wasn't told until after the installation was complete that the panels couldn't be tilted further South to take advantage of the winter sun. The panels were installed on a shop with a 2 in 12 pitch metal roof on steel purlins, requiring a ballast system. I don't think the panel install crew had ever installed a ballast system before. They put things in backwards and crooked and out of line. Wherever they made or used a hole in my roof, they pumped silicone into the hole and right onto whatever was under the roof; carpet, tool boxes, freezer, overhead door, car, etc...When I mentioned it to them they said they would clean it up, but they didn't. The install crew was gone for five hours for lunch and supplies. I was very pleased with the supervisor and electrician and thought they were very professional. I am still waiting to begin to use my panels, because I have no net meter yet. The monitoring didn't work because the shop is metal and far from my wifi source, so I had to run another conduit to the equipment to hard wire it to the internet. I had also pre installed conduit to the main breaker, but cannot tell that I was given any discount for that.
