Follow up
The staff in the office were continuously helpful after the install was completed. They answered operational and rebate questions. They followed up with emails and calls as required to help me understand the operation of the new batteries and meet the requirements for the rebates. The new system works as well or possibly even better than my expectations.

A great solar-systems company to work with!
I've worked with Photon Brothers for my initial 7500 watt solar-panel/inverter installation, and then again to have the panels upgraded to 9848 watts, with a new Tesla inverter. Each time their work was done on-time, with no issues, roof leaks, wiring problems, and with impressive integrity. Recently I had to have my Telsa inverter replaced due to a defect issue; they diagnosed it on-line, ordered it and came out to replace it under their warranty at no charge. Again the work was done with impressive results. I'd highly recommend Photon Brothers for their workmanship and integrity; they've also been around awhile while other companies have gone out of business. I have no regrets for having hired on Photon brothers.

Don’t waste your time
I do not recommend Photon Brothers. 1. The permit review process has taken 5+ months and was continually denied by the city for minor things that are in the company’s control for submission (ie what paper size to submit for approval on). The delay was caused by the project managers submissions and delayed responses. 2. After 5 months for permit approval, we were told they would install the next Wednesday. On the Tuesday before install, we received a call that they don’t have solar panels to install with no timeline insight for having inventory. It’s almost as if they had no visibility of the project. 3. We asked for the design document of what was approved for permit. We approved the initial design from Photon Brothers with 28 panels because that is what will meet the needs of the house. The final design document only includes 14 panels, so only meets 50% of the requirement. There was zero communication about the changes from Photon Brothers, and only found out because we asked for the final documents. In summary, the 5+ months we spent in permitting process is not what we approved and doesn’t come close to meeting the needs of the house, with zero communication about any changes. 4. To get anyone on the phone towards resolution is near impossible. This is currently in progress. I will update the review if progress is made.

Run away from this company
I am the next door neighbor of a Photon Brothers customer. I happily agreed to let them use my driveway for access to the project. When I saw the support poles go up over 8’ high, I bécame very alarmed as that would partially block views from my property and be very imposing. After numerous discussions with my neighbor and the company they we’re very unwilling to make any adjustments or even talk about other posibilites. When I asked the project manager about the design process and why it needed to be so high all I got was “do you want to see the permit?” No willingness what so ever to talk about possible solutions even after I offered four possibilities. When pressed, they said to make changes would cost 75k and that they didn’t want to delay their payment. This company only wants to install and get paid. They don’t give a darn about those who have to live with the sloppy crap they build. STRONGLY RECOMMEND NOT EVER USING Photon Bros.

5-stars for Photon Brothers
5-stars for Photon Brothers (PB). They designed and installed 18 panels of solar electric for our home 3.5 years ago. On a steep tile roof, not an easy feat. It has been churning out 10,000 kwh / yr over that time (exceeding our consumption by 22%); we sell power back to Xcel 9 months of the year. (Nov-Dec-Jan less sun; no surprise.) The SolarEdge software that links the control panel to my home computer makes it easy to keep tabs on how the system is doing (and double-checking Xcel’s monthly credits for solar production). I am writing now to note that, when one of our roof tiles disintegrated recently, the PB supervisor agreed that the combination of a hard-to-detect stress crack by the original installers plus 3.5 years of rain and hail may have caused the tile to fall apart. PB stood behind their work; no charge to install a new tile. BTW, the 18 solar panels themselves have all survived the wind and hail !

Bad warranty
Photon brothers installed our system just over a year ago. One of our 38 panels got spider webbing throughout the panel. We have had no extreme weather, hail, etc… No one has been on the roof. They want us to prove what went wrong. The warranty will not cover the replacement cost of the panel which is 1215.00 to replace. Not sure what if anything the warranty actually covers. Our set was 81,000 before tax credits. I think the company should replace this panel.

Initial Contact
Sadly, I would not recommend this company. Our initial contact was a text message trying to schedule a consult that was pushed out by a week to begin with. It was established that if you can't even meet a consultation phone call goal, you will probably have problems with the end result. So not further action was taken.

The Photon Bros. installed our solar and battery system about 3 years ago. My wife and are very pleased with the quality of the component installations on our roof as well as the ones incorporated into our power service area; very clean and efficient. Although our solar system has generally performed flawlessly, we have had a couple of component issues since the original installation. The Photon Bros. promptly identified and solved those issues. Many thanks to the design, installation, and service teams at the Photon Bros. I would highly recommend using the Photon Bros. for anyone considering installing a solar system.

Great Experience
I initially came across Photon Brothers when I was wanting to add a battery to my solar system, since we had been experiencing frequent power outages several years ago. The company that installed my panels was not yet supplying batteries so I did some research on the brand possibilities and local companies that install them. Photon Brothers offered me the best price by several hundred dollars, but more important, they had what I had determined was the best battery --Tesla-- in their warehouse. When the battery they installed the battery they discovered the inverter had gone out, so I went ahead and had a new Tesla inverter installed. They gave me a $700 discount as a returning customer. The new inverter revealed that my 15+ year old panels were not generating much energy anymore, so I had new panels installed. The quote was for a 4.5 kWh system, but before installation, they called and asked if would be ok to install larger panels that would give me a 5.1 kWh system for the same price. I agreed of course and am hoping that they will give me another discount for this. They came when they said they would and got the job done on scheduled. It is now delivering over 6kWh at the peak and has reduced usage of power from the grid to almost nothing. Katlyyn Arnoldi, with whom I dealt on the bids, scheduling and payment has been difficult to reach by phone, but she shares an office with Andrew Cavinta, who was the project manager on the battery project, and he is generally available and been very helpful.

Run!
Incorrectly installed inverters and racking system. Wouldn't honor the warranties. Terrible customer service.
