Fraudulently Activated Loan

GreenBrilliance fraudulently activated my loan. Their excuse was that my six month rate lock (already way to long to wait for install) was about to expire so they went ahead and marked my work complete and activated my loan. The funny thing is, after communicating with Dividend Finance, in order to mark work complete the installer must provide photos of the completed project to Dividend. GreenBrilliance had never set foot on my property either then or now. The thing is, I was left out of the loop for all of this. I ended up be informed via an email from Dividend congratulating me on my new system. According to Dividend this is relatively common practice, albeit in most other situations the project had at least been started. In my opinion GreenBrilliance is dead to rights and they have an open investigation with the VA Attorney Generals Office as well as DPOR.

Easy, simple and adorable

My coordinator was Evan Miller This is my first time getting solar so I did plenty of research. Green sage pointed me to Green brilliance and I'm glad they did. They were nice and professional. Even for someone like me who needs constant updates the communication was good and kept me feeling informed. So far love my solar.

Poor communication with delays

After receiving approval from my HOA the permits were submitted and I noticed the time was taking very long. I inquired on the status and was told the they were beholden to the county. I did another follow up with a long delayed reply and they said they needed to make changes to the permit. I proceeded to ask if it were possible to complete the project by end of the year so I can get the tax break for the next tax return. When this started on October 2022 they said it would not be a problem. More delays with the permits occurred. I finally got on the county permit page to discover that the team made multiple submissions, which appeared to be error on their side. This delayed the approvals by almost a month and could not install by December 2022. All throughout the response time was less than desired. Took 3 days to a week to reply, just to tell me no update or we will not be able to schedule as originally discussed. Once that was completed we scheduled the install. I noticed that the design was not followed. They installed one set of arrays in a different location. This change ended up delaying scheduling inspection as the county required the as built to match the design. After a couple weeks I noticed my bill was trending higher than usual but couldn’t figure out why. We were able to get the system inspected and turned on which is when I got access to the system via online portal to discover that my system was turned on and left on after the installation for 3 weeks. Because I didn’t have a net meter configured any over production was seen as consumption. The system was turned off after the inspection was complete. I did get this resolved and made whole. Poor communication, lack of understanding the permitting process, not following the design contribute to me giving GreenBrilliance a less than desirable recommendation. Taking 5 months for a small residential PV install is far too long. The equipment works fine. No issue there. They resolved my high bill issue. They want to make the relationship work but communication needs to improve.

Good Installer with excellent value

I selected Green Brilliance from the Energy sage marketplace. Their quote was the cheapest, with one of the best offerings for Solar panels and the best inverter in the market. It was not a bait and switch, the cost provided in energy sage was very close to the final cost (I added extra panels which increased the cost). My Sales rep John Lee was informative and upfront in the sales process. Once the project moved onto the implementation phase, the Green Brilliance team took care of doing all the paperwork for HOA, Utility Company, and County. There were a few delays in the project, but I am happy with the installation. I was always able to reach the Implementation team when I have questions or concerns. I would recommend Green Brilliance to any potential client thinking about going solar.

Look elsewere

3.14.23 Update: Panels have not yet completed inspection and no communication from and follow up by the GreenBrilliance team. Beware of newer positive reviews, they cannot be from real customers. Read the reviews carefully, here and elsewhere. This company will ghost you shortly after the contract has been signed. The sales process estimated twelve weeks from contract signing to system turn on. Not true, at 20 weeks and counting. They will low ball the estimate to get you to sign and then take their time to file plans and permits, install the panels, schedule inspection. Given my experience with them to date, I concerned about their ability to maintain the installation should something go wrong. But for now, just hoping to the system goes live soon. The project manager does not communicate. It takes several e-mails to get a response. Poor customer service in every regard. If I could redo, I would have chosen another company, paying more for better service.

Love solar power

We had a great experience with GreenBrilliance installing our solar panels (spring/summer 2022). We had shopped around with a few other companies, but GreenBrilliance had the most competitive quote for the timeline that we preferred. Our consultant John Lee did a great job setting up the site visit and drawing up a contract that fit our needs. Throughout the installation process, GreenBrilliance had good customer service, keeping us appraised of where they were in the process and what we could expect next. In the end, we paid more than we had anticipated, though this was due to our roof being in worse shape than everyone realized. GreenBrilliance worked with us and the roof contractors to ensure that the final price was fair. Since installation, we have much enjoyed our solar panels and have not had any issues.
