Reviews frequently highlight smooth installations, clear timelines, and responsive follow-up when components need replacement. Several customers mention predictable scheduling from contract to PTO. Some feedback notes delays in communication during permitting or after installation, especially around battery activation. Overall ratings reflect strong satisfaction with workmanship and support once service is engaged.

The installation process with Ipsun Solar went smoothly and the company responded promptly to any issues that arose. I can confidently recommend Ipsun Solar to anyone interested in the installation of solar panels.

The whole process worked pretty smoothly. There was a predictable gap after signing a contract before work began but I didn't have to do anything and they contacted me when all the approvals were in place. Installation happened in a day. PTO was a couple weeks after that. A week after PTO they contacted me and told me that one of the inverters wasn't working so they came by and replaced it. Since then, for the last six months, there have been no problems.

I promised Ipsun a glowing 5-star review if they managed to keep up the good work, but they didn't. I got a LOT of proposals for my solar panel job and Ipsun was one of 2 companies that had solid contracts and lower price than others. They were even willing to fix clauses in the contract that were objectionable - something the big companies refused to do with the usual "trust us not to screw you" response.

My salesman/liaison George was great throughout the process. The engineers insisted on submitting 2 unapprovable designs to county permitting, but still managed to get the permit ahead of schedule. Then came the ecstatic surprise of almost immediate installation (this, with tax credits expiring and everybody rushing).

It was downhill from there. The crew left a lot of trash, especially the electrician that worked on my breaker box. I hope their work is better than their workmanship. I was promptly billed and paid for completed installation in early November. After some hiccups, the system passed inspection, in plenty of time to get the tax credit and well ahead of their estimated installation date.

But then things completely fell apart. The 15 minute process to request Permission to Operate took over a month. They sent me a bill for PTO being approved in case I wanted to pay early (I didn't). They didn't update the details of the installed configuration with the utility, so the utility didn't approve. I finally complained enough to get them moving in time to get permission to operate on December 31, in the afternoon. The post-PTO liaison that contacted me by mistake a month before PTO never contacted me after PTO. I might have upset her while pushing for PTO.

In summary, Ipsun charged me a better price than other proposals. They got me the tax credit that they told me there was only a slim chance for because of my late decision to install solar. George was great to work with. But the end-of-year crunch that almost lost me the tax credit that I was ecstatic to have within grasp, and that caused me to beg them to enable, killed the fifth star and glowing review.

They still got the 4 stars. I paid less than other big companies quoted. And I can recommend people that don't trust contractors that propose unfair contract terms to get a proposal from Ipsun.

Rose Hendricks on Ipsun Solar

We're deeply disappointed with our experience with Ipsun Solar. We purchased a battery backup, and there was a long period of silence between installation and permission to operate. We received permission to operate conveniently right after we followed up after several months of silence. Then, following the permission to operate status, we had press again in order to receive instructions to turn the battery on. We received a pdf for us to follow the instructions on our own. When we did so, the entire house lost power. The Ipsun electrician was able to restore power to the house, but not to fix the issue with the battery. In the days that have followed, we ask for an update each day and receive either radio silence or deferral of responsibility to the battery manufacturer. In addition, as a result of the battery issue, our solar panels (not acquired through Ipsun) are now not functioning. Overall, communication, project management, and follow-through have been terrible.

UPDATING this post as communication improved and Ipsun was able to get the issue resolved. We now have a functioning battery, which resolved the issue with our solar panels as well. We appreciate all that Ipsun did to get things back on track.

David Fischer on Ipsun Solar

One of my solar panels failed this summer. I only discovered it three weeks ago checking the app and seeing a tiny alert. It took a couple weeks of contacting Ipsun to get in contact with the right service team. But once they got on it, they worked the problem, figured it out with a couple of house calls and roof climbs, and ultimately replaced a faulty panel under warranty.

Because my panels are from 2019 and hard to get now, I got a newer one about 20% more powerful.

Ipsun is my original system designer and installer. I'm glad I chose them to do the work. They've worked with on a couple of items over the years. I recommend them to all my neighbors considering a home solar install.
