    Imagine how bad your experience must be to purchase and put up a 2 ft  3 ft sign in your yard.
    Owen J.

    I'd give zero stars if I could. They talked me into getting a Tesla Powerwall 3 since the rebates made it almost free. The battery doesn't charge or discharge properly and they are claiming that nothing is wrong and that nothing can be done. Essentially, I now have the equivalent of a $13,000 inverter. Do would not advise anyone to use Photon Brothers and, whatever you do, don't buy a Tesla Powerwall unless you want to overpay for what is effectively an inverter at this point. Update: Once again, my Powerwall 3 isn't working. It is stuck at 67% charge and stopped powering my house last night. I've now put signs up in my yard that say: "I hate my Photon Brothers installed Powerwall" and I've ordered magnetic bumper stickers with the same statement to put on my car. Signs are going out to some family members that say: "I don't trust Photon Brothers" to put in their yard. Overall, my experience with Photon Brothers has been extremely negative and I strongly warn anyone from working with them. Please note that this is the first time I've left a negative review for a company on Google Maps. I've had large repairs/improvements not go as planned, it happens. A few years ago I had a company install a minisplit heat pump so my family could cool their bedrooms. They were training some new installers and a bunch of the refrigerant line connections leaked. It took two summers to find all of the leaks but I felt that the company was supportive and determined to get the problem solved. While the experience was frustrating, I was always thankful that I had these issues heat pump with that company because I knew they would get the system working. This not how I feel about my Photon Brothers experience. At this point, I hate my Photon Brother's installed Powerwall. It has been over two months of dealing with them and I have no hope that this system will ever run properly. From this post, you can hopefully see that this has been a lot of work for me and no progress has been made. You should probably ask yourself if you want to pay extra for a battery and then end up spending a bunch of time trying to get it working properly. I know I had better things to do with my time, you probably do too. My advice, don't do it, you don't need the hassle in your life.

The team ran into some problems that were outside of their control and handled them extremely well. The spray makes a mess but they covered beforehand, and then cleaned up very well afterwards. Re cost, I obtained seven estimates. Only two came in cheaper, and I those estimators did not leave me with a good level of confidence that they would have quality work.

    We purchased a new home in '21 and knew we wanted to do at least three things right off the bat: 1)…read moreinsulate the attic, 2) install solar, and 3) an EV charger. I was pleased to find that REenergizeCO did them all and were more than just an installer but on mission to increase energy efficiency. From start to finish communication was fantastic. They first did the insulation and we noticed a difference almost immediately. They also took care of submitting the Xcel rebate paperwork for it. The solar panels and EVSE came a bit later. Again, they took care of all the paperwork with Xcel. The system has been working without flaw since and saving us tons of money in this inflated energy cost environment. We had them out recently to detach and reset the panels for a roof replacement. They took the opportunity to slightly tweak the layout for better efficiency. Still the same commitment to quality!

OGS were great at communicating, accommodating to my schedule and got the work done at a fraction of the price quoted by others. The two gentleman showed up on time, were courteous throughout and made sure I was 100% satisfied with the project. They even made sure to get everything cleaned up and left how they found it - even better. Would highly recommend this company and I wasn't paid for this review. Great job, thank you!

    One star is too generous for OGS, Off-Grid Solutions. I wouldn't trust OGS to replace a lightbulb…read more I had to hire an experienced journeyman electrician to do a forensic inspection of OGS' work and the inspection found numerous code and safety violations by OGS that required remediation. Some of the OGS' mistakes could have caused a fire. The inspector commented that the (OGS) work appeared to be done by an inexperienced person. OGS failed at every step and then extorted me to pay them immediately in cash before the work was complete and before the City electrical inspection. The even clumsily FORGED a changed contract long after the "work" was finished, changing the terms; I had never seen that contract version until 6 weeks after the work was supposed to be completed. I have since learned from OGS that an "apprentice" may have been used on the project, mostly unsupervised, which is illegal in Colorado. I believe that the reason they wanted cash before the inspection is that they didn't not expect their work to pass inspection. We had a detailed contract for a straight-forward electrical panel capacity and amp upgrade. The contract specified that two employee electricians were to take one day to complete installation of a detailed list of equipment and get the permits and inspection done. They sent one (not two) freelance "electrician", who appears to be just an apprentice who is not allowed to work without in-person supervision, who had never seen the work order and did not have a copy. The "electrician" brought and started installing a breaker box that was the wrong brand and 1/3 less capacity than the minimum specified. After a 2nd day of work, OGS were still missing parts, but demanded full cash payment; they said it was too much trouble to bring the remaining necessary parts soon. OGS deliberately delayed requesting City inspection for no valid reason--a homeowner was home every day in January. They threatened to sabotage my follow-on project if I did not pay them cash immediately before the contracted work was completed and inspected. And did. The contracted work is still not completed, weeks later. After numerous threats, I may file extortion charges against them and seek a form of restraining order. IMHO, the GUYS AT OGS ARE NUTS and certainly should not be licensed electricians. The OGS reply to this has substantial misrepresentations; no surprise. Deal with them at your own peril.

We live…read morein an older ranch that had very minimal to no insulation and we were struggling with heating and cooling our home for many years. After shopping around they were able to give us exactly what we needed and we already notice a difference with the mini heat wave that we are having currently here in Denver.Scheduling was relatively easy and we were able to get on the calendar within a month. Pricing was competitive and they offered to price matching should we find another company that we liked. Other companies, however did not offer as many services for the amount that we paid. Guardian is also filing our upgrade with Xcel energy so that we get all the offered rebates that we don't have to do that ourselves, which is definitely a nice touch. The installers arrived in a timely manner, and were done within one day with a job that was estimated to take two. They also kept things tidey and cleaned up once finished. We also had a ton of questions and Brian, who helped us, was always able to reply and patiently explain things. He was incredibly flexible with planning to our unique situation, and was very knowledgeable. From the beginning, he gave us a bunch of literature, as well as testimonials, and a résumé for the company which definitely put us at ease at the level of experience that was held by Guardian. I would absolutely recommend Guardian for any insulation needs that you may have for your home; And I wish I could say that we would use them again, but I think that our problem is thankfully solved all thanks to them.

Then next one that came looked in the attic and took measurements before giving a quote. When Brian with Guardian Insulation arrived, he took the time to understand why we wanted insulation. He explained the work they would perform, even sealing all places, like electric line holes in the walls to prevent air leaking in or out of the house. He showed how this would apply for a rebate Excel Energy, and we received a $600.00 rebate too. They also provided an energy audit checking for air leaks in the house, before and after the work. The price was competitive with the other companies and the work was performed in a professional manner, cleaning up before they left. I would highly recommend this business.
