1Solar — Colorado - Centennial, Colorado

Ezra has performed well representing my repair needs. He has kept me in the loop about what the repair work entail, scheduled technician arrival, then he followed up with me to be sure the work was performed to my satisfaction. I recommend 1 Solar because of their attention to your system needs and prompt follow through with any questions I had. Good customer service is hard to find these days and 1 Solar shines with their customer service.

The staff at OneSolar has been very kind and helpful throughout the process. Ezra has been our main point of communication and has been great. All of the technicians have been good as well, including Ryan who was very good at explaining things in a way we could understand and answering all of our questions.

As in a previous review, I wanted to give a 2.5. The problems we have been having are primarily due to a lack of communication. The owner of Valor Roofing and Solar (the company that sold the system)was out to our house after we had a bad experience with the first sales person. We were able to upsize the system to our needs, and we're starting to save money on our electricity.
From what I understand, 1Solar is the installer used by Valor.

Communication between the installers and us was terrible. Almost every time they came out to work on the system, or when an inspection was scheduled, we did not receive a heads up ahead of time. Sometimes we needed to let them in the house, and luckily we just happened to be home.

The rest of the problems are with the so called concierge they assigned. Before installation had begun, he was sending out emails every week to update us even though nothing was happening. Since then, he has never reached out, and when he answers my emails, he doesn't follow through on his promises.
We have been trying to get snow guards for the solar panels since May when our gutter installers recommended them. Without them, the snow will melt such that it sends down an avalanche that will take out the gutters. Eduardo said I need to buy them from the company or my warranty will be void. Eduardo sent a picture of them, and he said an invoice that needs to be paid before a work order can be done. There was no link to send payment. I've emailed multiple times over the last week and a half with no luck, and called to leave a voice mail with no response yet. Then I called the secretary of the owner of Valor Roofing and Solar with no response from her yet either.
Now it's October. The snow will be here soon, and we're no closer to getting the snow guards than we were in May!

I know this is two different companies I'm complaining about, but I think subcontractors need to communicate with the general contractor.

Giving 2 stars since 2.5 isn't an option. Its not that it is a bad company. They just don't seem to be competent. We have had their solar panels for a couple of years now and it has been a very rough road. At first, we were told that we don't use enough electricity for the program. Then we were told that we could purchase as long as we bought 2 extra solar panels to meet the minimum requirement. So we bought the "2 extra." Unfortunately, they haven't produced enough electricity to meet our needs so we are paying for solar panels and an electric bill. There was also the numerous times our panels went down. We lost months of production and had to have them come out to repair multiple times. After a few months with no production and multiple repair technicians, they finally found a loose neutral wire was causing the issue. When we asked to be compensated for their error, we were denied. I would definitely recommend finding a solar company that stands by their work and makes it right if they make a mistake. I wish we had gone with a different company. I wish our "2 extra" panels produced enough electricity to meet our needs. I wish we hadn't have had to push and push and push to get the things our salesman promised us (electrical panel upgrade and attic insulation). I wish I had done more research before choosing this company. I am now stuck with a system that is insufficient.

Ezra has been so lovely to work with! He's quick to communicate updates about my project to me, and talking with him about my project doesn't feel like just talking to a rep about business - his friendliness makes him feel comfortable to talk to and gives me a sense of trust that I'll be in the know of what's going on with my project every step of the way.

I am not giving a positive review do to: they do not fulfill their promises, they outsource their work, phone number they give you can never reach anyone, can only text that number. That company (Nova Source) canceled 2 appointments & took them 3 months to finally come out here. I had to pay a lot higher utility bill & being on a fixed income it was very hard to pay it. Plus having to pay for our non working solar! And no one seems to give a hoot! Except for: one tech that had to input our new serial number & got the system working again.

1Solar took over fulfilment of the service I originally arranged with Titanium Solar. Much was lost in the transition. But we did work it out and as of a few hours ago my system is generating power!

Most od the stars in my review go to the customer support team. Deb, Sarah, and Hunter especially; each was responsive ans receptive and helped to clear up the confusion when it would manifest.

Last year 1 solar hooked up our solar panels, on 9/24/2021.
1 Solar employees drilled a hole into my roof and just filled it with caulk, and did not replace it with a new shingle.
I was told this would be addressed but it was never taken care of and no one from the support team is responding to this issue.

1 Solar also ran a conduit along my roof (Which looks terrible), apposed to going through the attic. They decided to cut through another shingle to do a right angle turn.

Avoid this company
