Photovoltaics (PV) is the conversion of light into electricity. I didn't take physics in school but…read moreI did ok in math so let's take a quantitative review on PhotonBrothers (PB). It's important to understand that PB is a installer not a manufacture. Different manufactures have different models. EnergySage.com is great for general research panel efficiency: SunPower: 22.8% LG: 22% REC: 21.7% PB is a certified installer for REC group a Norwegian company that started in 1996. My specific solar panel model number is REC355AA (alpha series with HeteroJunction HJT cell technology (RECgroup.com) My system: 14 REC x 350 watt panels producing 4,900 (4.9 kW) total solar power. To put this number in perspective, a typical 3 ton central A/C system consumes about 3 kW when it's running. Timeline it took about 3 months from initial call to certification. I went though a co-op with city of Denver (SolarUnitedNeighbors.org). Read up on "Net metering" and "Investment Tax credit ITC" renewed 26% for year 2021-2022 Everybody from sales: Krista T. Projector manager: Eric H. And installers: Jerry & Kyle they were all competent in their lane of work. They all praised their management and liked the company culture. Solar can be purchased with cash or financed with a 20-year loan just like purchasing a car or appliance. It's an investment for your house and your money saving won't break even until around year 10. Loan payment will be around $80-150 per month depending on the kW size of your system. Your electric bill will be significantly reduced to nothing but you still have to pay the $6 monthly service fee plus your Natural Gas utility bill. Most panels will have a 25 year warranty but the biggest difference is Tesla SC330 panels only guarantee Output of 80% efficiency at the end of term. REC355AA panels guarantee is at 92% efficiency.

My experience with Photon Brothers has been nothing short of infuriating. I want to be absolutely…read moreclear so nothing gets lost: the communication, customer service, and basic professionalism I received were shockingly poor, and I deeply regret choosing this company. Photon Brothers wasted 6 months of my time and cost me roughly $17,000 due to their negligence. I repeat, DO NOT UNDER ANY CIRCUMSTANCES CHOOSE PHOTON BROTHERS. There are many solar companies out there, take your business elsewhere!! This is a company that puts customer service LAST and will throw you under the bus and leave you hanging the when issues arise and they need to do something that inconveniences them or impacts their bottom line despite contracts, written and verbal promises and basic honorable/professional business norms. Our family moved into our new home in June and immediately began comparing solar proposals. I ultimately chose Photon because Sam Johnson (senior sales rep) appeared knowledgeable. I was explicit with Sam about the type of roof and shingle I had--I even sent him the official documentation from the roofing company detailing the type of roof and shingle. He assured me multiple times that Photon could handle it and told me he had built extra labor costs into the contract for exactly that reason. We signed a contract and approved financing. Then came the site visit with the installation supervisor, Drew Perry. I was on the roof with Drew as he inspected everything. He told me directly that the roof was suitable and we were "good to go." Every step of the way, Photon reassured me the system would be installed before year-end so I would receive substantial expiring federal tax credits. Throughout this process, I repeatedly checked in with the project manager, Kaitlyn Martinez. Responses were rare, slow, and unhelpful--but when she did reply, she also confirmed everything was on track for installation before year end. Install day--November 24--was when it all fell apart. Only that morning did the installation team realize they had completely overlooked the shingle type and couldn't install the system, even though I had disclosed this upfront and even though their own supervisor had inspected the roof in person. The install crew told me they messed up and would make it right and still get it done before year end. Kaitlyn (project manager) called--one of the only times she ever did--and assured me there would be no added cost and they would still complete the project by year end, I was reassured again that they would uphold the contract and their promises. That turned out to be untrue. After several incredibly frustrating conversations with Sam and co-owner John Johnson, where I had to constantly call them for updates, I was finally told that Photon would NOT complete the project at all. They openly admitted they made the mistake but refused to honor the contract or their repeated promises because it would cost them more in labor. John specifically told me that--even though the error was entirely on their side--they were not willing to take the financial hit to fix it and I was just out of luck. They refused any sort of compensation for my lost time and money. John initially tried to blame me because I had a difficult roof, then blamed Drew Perry (instillation supervisor), then blamed his Ops team then just told me verbatim "construction is difficult" and I need to understand that, so too bad for me. As a result, I've lost more than six months of time and a ~$17,000 tax credit, all because Photon Brothers failed to do their job, failed to communicate, and then refused to take responsibility for their own mistake. Based on my experience, I would strongly caution anyone considering this company. They overpromise, underdeliver, and when their internal failures come to light, they deflect, delay, and ultimately leave the customer holding the bag. I cannot recommend them under any circumstances.

We first met with the company's president, Willie Mein, to discuss how the entire system operates, as-well-as details about the different components of the system. Willie invested quite a bit of time, including climbing around on our roof, to create a custom design for our particular home. The installation of the system was quite an undertaking but the installers accomplished it in a timely and professional manner. We've been very pleased with our system due to the significant reduction in gas usage to heat our water over the past three years. Our system had been problem-free until we recently noticed the hot water heater being activated when it shouldn't have been. We called Custom Solar to see if they could service our system to determine the problem. Their responsiveness was impressive. Eric, a valuable technician, did some troubleshooting on the phone but then offered to stop by our house on his way home from work. He was quickly able to ascertain that it was simply a matter of the plug being slightly disconnected from the outlet. Should we have needed a replacement part, Custom Solar would have been able to repair the system within a day or two. They have been very committed to providing excellent customer service throughout every step of the process.

One star is too generous for OGS, Off-Grid Solutions.

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.

They have provided great support in answering our questions after the installation. For example one of our micro inverters failed and they came down the same day to replace it, even though it's a 1.5 hour drive from their location to our house in Denver. They even helped us apply for Denver County rebates and provided the needed information for our EV Charger rebatel.

I also informed him that I intended to leave an online review. During our conversation, he responded by saying, "I'll sue you for defamation." And, " I can't wait to see everyone on Reddit laugh at you" That response made me question whether customers feel comfortable leaving honest negative reviews after receiving that kind of warning. Based on my experience, I cannot recommend this company. I encourage anyone hiring these contractors to have security cameras and to document the condition of their home before and after service. In my opinion, moving a customer's security camera without permission is a serious security concern. Xcel's website has a list of companies you should use I'll provide a list below.

I thought it was weird Rex Roofing was interested in the job I initiated as a Yelp Project because…read moreI haven't seen anything remotely resembling my 1200sqft 1970 ranch house on their website or socials, and I'm in Longmont while they're based in Castle Rock. Stay far away from them if you're not in a reasonable service area. They are an insurance claim chaser company and will step all over you to get at your payout. They sent different people out to inspect and provide quotes (gutter and soffits/fascia was the scope requested). I did not ask for a roof assessment but the gutter guy thought it might be eligible for an insurance replacement, so I said sure send the guy on out and let's see what happens. That's where it got really.... interesting. My first appointment was for a Friday. I asked for a specific time so I could manage my work schedule around the inspection. A time was agreed upon. Nobody showed up. I had to initiate contact to find out that they would not be coming that day due to the time/distance. We rescheduled and on the rescheduled date, I reached out early to confirm the time and was told the inspector would be 30min late. I readjusted my work calendar and was notified it would be an additional 15min. This turned out to very much work in my favor. The inspection was very thorough and took about 1.5hr. At the conclusion of the inspection I was told they can convince the insurance company to replace the roof. They showed me what ended up being a contract, but was not presented as such explicitly by name. I was asked to sign before they revealed the "fine print" on the back page - which involved having the insurance company sign the check over to Rex Roofing rather than me (I have USAA). This didn't sit well after discussing with several people and reviewing the fine print. I voided the contract within the 72 hour grace period so I can get a second opinion, gather additional quotes, and control my own insurance payout (if that happens). Instead of responding to me to confirm they received my email (always document in writing! With time stamps!) they forwarded it to the inspector who started texting me asking to "resolve" the situation. I explained, as I had in the email, that I would be taking my insurance payout myself and I requested a "cash price" quote from them. I was then told there was no way my insurance company would approve it without the inspector present, a number of wild assumptions and insinuations were made, and I was essentially berated by text by the salesman for exercising a legal right to void the contract. I had to block his number because he would not stop texting me to mansplain how I had no idea what I was doing as a homeowner and he was the only person who could convince my insurance adjuster to cover the roof. Turns out he was right - they talked me into opening a claim, the adjuster said the roof is perfectly fine and they would replace only one portion of one downspout that had hail damage. I can't tell you how the "value" of this company compares to others because they said they would do the work "for a price agreed upon with the insurance company" without providing a scope of work or any numbers of any kind in writing - so I guess they're not really interested in much besides doing the job for as much as they can squeeze out of the insurance company. I might not have made a USAA claim myself but everyone else in my family has.
