    Unprofessional, pressure-sale tactic, model calculations not up to date, price inflated.

    Chris and his team took care of the entire process while we didn't spend a single penny out of our pockets for installation.

They were not the cheapest quote, but they were the most thorough and well-thought out. Scheduling, payment and installation all went like clockwork. Exceptional crew, highly efficient and professional, cleaned up well. Excellent communication throughout. Got a beautiful new roof that I'm very happy with. Highly recommend without reservation.

Where other contractors canceled appointments, arrived late, or were just no-shows - Mikel (out of their Hudson office) arrived on time and did a thorough assessment of the roof including taking drone footage. He sat with me and walked me through the whole process clearly, explaining all my choices in materials and didn't push any product or add-on. I did receive marginally cheaper quotes, but they did not leave me feeling like my home was in good hands in the same way that Mikel did, and I felt the extra money was likely to be worth it. Once I decided to go ahead with them, again, everything was done very professionally. I was kept informed of times and everybody showed up exactly when they said they would. I made a small change to the scope of the work in replacing additional plywood sections of the roof, and these were easily accommodated on short notice. On the day of the work, the crew showed up on time and Jurgan (the site foreman) kept everything moving with minimal disruption to us. I was working from home, and my wife and kids were in and out of the house for school and errands. Despite replacing the entire roof of the main building and two additions over approximately 9 hours, there was minimal disruption to our days. The house was protected during the work, and even with snow still on the ground, their cleanup crew constantly walked the property picking up and disposing of any debris, nails, old material etc. Ultimately the roof was replaced successfully and looks good. Every step of the job was explained to me, every question answered, and every decision explained. The team was professional, punctual and courteous throughout. A couple of weeks in and we've had snow, rain and strong winds. Everything is still perfect. I can highly recommend Mikel and Jurgan from Golden Group, Hudson.

I was immediately connected to a human vs. an AI bot and have been guided through the process by the entire way. Randi had been my trusted guide and has been incredibly transparent the entire way. From the honest sales, pricing, and "human-centered" payment structure their approach to sales and support truly sets them apart. My install was smoother than I could've imagined and the install crew was informative, honest, and methodical in their set-up and clean-up. Deepest thanks to Cody, Jay, Mike, and Sean for getting us set up and running. Highly highly recommend and would work with them again.

After doing a little research and asking around we chose to go to with Isaksen Solar and I HIGHLY RECOMMEND! From the very first consultation to the final installation, our experience was excellent. They took the time to explain the process in detail, answered all my questions, and made sure I felt confident in my decision to make the change to solar. The installation crew was on time, respectful, and worked great together. They completed the work on schedule and left the working areas exactly the way it was when they arrived. I couldn't be happier with how easily the system was integrated with my home, both aesthetically and functionally as seen in the pictures. Their whole team outdid themselves with their commitment to me as a customer from start to finish. They followed up after the installation to ensure everything was running smoothly and that I understood how to monitor my system's productivity. If you're considering solar, Isaksen is definitely the way to go! They made the entire process easy, transparent, and worry-free.

    SO AWFUL!! Completely untrustworthy liars. I made an appt for a $49 "service call" for Friday,…read moreand actually moved/cancelled all my patients for that day to make it work, as that was their first available time. I'm re-doing the kitchen, need an electrician to bring it up to code-- and I wasn't sure exactly what I needed done. (Because they need to know.) I called 3x the week before to confirm the appt. Two days before the scheduled appt they ask me to move it up a day, to Thurs, the next day. I say fine-- thankfully I had cleared that day too. I then hold off doing work on my floor so the electrician will be able to walk on it the next day. I ask if the electrician will be able to do any work on this "service call" but I now hear that the "service" described is just giving a quote. The receptionist says she'll find out if any other work can be done. I'm surprised that the appt wasn't booked with this in mind, as I had requested. Anyway, she calls me back when I'm in the middle of work, and says she needs to hear back by 4pm (in 10 minutes!) whether I still want the appt. Then she calls the next morning to say that appt is gone, as is the Fri appt! At this point, I don't trust this company AT ALL. I never said I didn't want the appointment. An appt had been scheduled. If someone calls the customer to say "I need to hear from you in the next 10 minutes or I'm not coming tomorrow" that is pretty outrageous. Perhaps worst of all was hearing her lies defending this unprofessional, unreliable, deceitful practice the next morning when she informed me she cancelled. She said she'd been trying to reach me. If this were true, why was I not informed every (any?) time I called? This is not the way to run a business. Also, requiring that the customer know exactly what is necessary before booking an appointment is not the way to run a business. Charging $49 for a quote but calling it a "service call" is not the way to run a business. Nor is lying. But moving and then cancelling an appointment capriciously, with ridiculous rationalizations, is so disrespectful and unprofessional. DO NOT TRUST THESE PEOPLE. It messed up my work schedule, and my whole kitchen remodel schedule, delaying it at least a week. In the future I'll call an electrician who can answer my questions directly, book his own appointments, is straightforward and honest, and doesn't charge for a quote and call it a "service call."

    I talked to absolutely every one about a solar panel installation. I easily spent months on…read moreresearching the topic, vendors, and installation techniques. Ultimately I settled on on a mechanically mounted system for my flat roof, which was wonderful. Some vendors would not touch a flat roof. Some only installed ballasted systems. Some vendors assumed that they could use a lift to get onto my roof when they actually needed a crane. Some just wanted to overcharge me with the hot new technology, sweeping the nation. After reviewing multiple bids, I settled on Sunbug to install my system. Chris Miller was a no nonsense saleman throughout my whole research phase. He answered all of my questions, and disabused me of any misinformation I may have had. He was polite, but firm, which is exactly what a layman consumer needs when making a large, delayed gratification purchase like a solar system. Once I signed on the dotted line, their team actually moved fairly quickly through the rest of the process. We were able to install my system before the end of the tax year, so some of that delayed gratification is delayed just a little less. I would give a five star review, but there were a few hiccups. Once I signed the dotted line, the team was less responsive than I needed with my subsequent questions. They installed the inverter in my basement without my input, which is a problem when I plan to finish my basement. We quickly fixed that by simply moving it, but we could have avoided that problem altogether by filling me in on the plan first. I chalk that up to some disorganization, and rushing to complete systems before the end of the tax year. Another silly issue is that their electrician upgraded me to a 200A panel, which is wonderful. For some reason though he reinstalled the same 100A main breaker I originally had, which makes no sense. Now I have to pay some one else to upgrade my main breaker. A month later I am actually still waiting for an inspector to check off on their work so that I can turn the system on, but that may be more an issue with the inspector than with Sunbug. In any event, I am mostly pleased with my purchase, and look forward to bathing my roof in sun shine in the coming years.

    They never returned my call. So I can't speak to their work. They were highly recommended by a…read morefriend in MA. So I'm disappointed

    I have been dealing with this company for almost two years now and have had nothing but one bad…read morecustomer experience after the next. I made the mistake of signing up at their booth in Home Depot and have been paying for it ever since. It all began with signing up in October and being told that my system should be installed and running by May just in time for peak production season. After I signed all the paper work I never heard anything back. Finally last July I contacted them and after Several attempts managed to speak with someone who informed me that my project had gotten "Lost". They expressed their deepest regrets and apologies and told me I would be fast tracked as a VIP account. Which apparently meant another 5 months of waiting. So I finally did end up with Solar Panels in December 14 months after I had originally signed up. Fast forward 2 months to February and I have water damage all over my living room ceiling. After I contacted them they were very prompt about sending out someone to take pictures and then a few weeks later another person showed up to take pictures. Fast forward a few more Months to July and no one ever came back to actually fix the problem. After an email and multiple phone calls I have been told that nothing was done after the pictures were taken and that they in fact never actually did anything with the pictures so they are now going to need to send someone out a third time to take pictures. So while I would say that Solar panels are a worthwhile endeavor do not use NRG. I recommend to all my friends that they use any company they can find but them.

Met the sale representative and every looked good so we signed up. That was august, the panels were installed free on October and now its January 2015 and they are not turned on. Sent emails and made calls and finally spoke to a Rep at base head quarters in Houston , TX. The local building inspector is all set, local utility company is all set. The only missing is that the paperwork at the headquarters has not been completed. August to Jan.... I have not paid a thing to this company as i have no bills. But it seems that the solar panels are generating energy that is going to someone. Just saying, do not be in any rush dealing with this company. Steve Vayo Grafton, MA
