Leaking Roof, Misleading Info, Incomplete Installation, etc

Signing with GreenBrilliance has been a disappointing experience. On the one hand, their proposed timeline was quick and the system is working ok. On the other nightmarish hand...everything else. Communications throughout were inconsistent and there were frequent problems with details. They struggled with the contract--they misspelled my name. They struggled with the payments--they couldn't find the money we wired them for a few days. They struggled with installation--they mistakenly had system materials delivered to our house instead of to their warehouse without warning us. So we came home the day before the installation to find the inverter and other elements (another large box, dozens of bolts and long metal poles for mounting the panels) sitting in our front yard. They were apologetic about this, and I was able to move everything into the house, but I can't help wondering what would have happened if I'd already left for work before this was dumped on my lawn. Inverters aren't cheap! What would have happened if it had sat there all day? BUT: our real problems started *after* installation... See, we were determined to install panels *without* drilling holes in the roof. We'd seen panels mounted on the parapets of rowhouses before, and that's what we wanted. This was very important to us, so we asked GreenBrilliance if they drilled through the roof when they installed panels. They assured us that there would be "no penetration involved and no drilling involved." Again, I cannot stress enough that this was very important. It was our final question before signing a contract with them! Our panels were installed in spring 2022. It was a mediocre experience (see above). But then: we found out that GreenBrilliance had misled us about their solar panel installation! They did, in fact, drill holes in our roof! Almost worse...they didn't perform that (unwanted by us) installation correctly! We had our first roof leak in fall 2023. GreenBrilliance's roofing department came out and explained that the holes in the roof hadn't been correctly caulked by GreenBrilliance. We had our second roof leak in spring 2024. GreenBrilliance's roofing department came out and explained that there were still other holes that hadn't been correctly caulked by GreenBrilliance. I complained to GreenBrilliance about this misrepresentation, and they promised to look into it. For the past 3-4 months, their main response has taken three tracks: 1) to first insist that they're conducting an investigation, 2) to subsequently try to convince me that it is, in fact, best to have holes drilled in solar panel installations, and 3) to stop responding to my emails and phone calls. Upshot: we've been very disappointed in GreenBrilliance's effectiveness AND in their customer service. They misled us about what they were going to do to our house--and then slowly stopped responding to me after I insisted on them reimbursing us for that misrepresentation.

GreenBrilliance PV System underperforms contractual output by about 12% and falling.

This is a long term review after 22 months of operation. I compared quotes for a residential rooftop PV system in SW Pennsylvania from 6 companies and chose GreenBrilliance (GB) as the lowest cost provider. There was about month delay due to their submission of a permit request to a neighboring local government. System installed quickly once approved. It took about 3 months after installation for the bi-directional meter to be installed, but most of that time is likely due to my local utility and not GreenBrilliance. System has been operational for 22 months with no downtime or repairs. However, the system output is below the output specified in the contract. For the first 365 days, output was 11% below contract specification and for the most recent 365 days, it is 12% below. Even a calculation using the best Jan, best Feb, etc. since the system has been operation is 8% below spec. And these are values for a brand new system, which will degrade with time. My roof has no shading by trees or other objects, so that cannot be a source of lost generation. I contacted GB about the underperformance. After some delay, they replied that the system is operating fine and they will not do anything to address the underperformance with respect to the contract.

Can't meet their promises

We are in process with GreenBrilliance and throughout they have failed to meet their promises. Delays in submitting or resubmitting permit application. Missed their scheduled dates and the follow-up dates.

THE BEST SOLAR COMPANY IN THE MARYLAND, VIRGINIA AND DC AREA!

I got proposals from 6 companies through Energysage and 2 from other companies. Peter Kyle the solar consultant from Green Brilliance not only offered the most efficient panels with the best warranty and the newest most powerful Enphase inverters but also the best price and service agreement. Peter also took the time to make a design that made me and my wife happy. I signed the contract February 13 and on Feb 14 Anmol Mangla the Field Engineer came to our house as scheduled to do the site survey. He took care of all the plans and permits in a couple of days. There was a couple of weeks wait on Montgomery County and Pepco Power Co. to approve the permits and interconnection. Then Evan Miller the project coordinator worked out all the details and got the installation scheduled for March 20. The install crew did a great job putting the panels in the correct place, Jose the electrician got my approval before installing the rest of the equipment. Everything was done perfectly the same day.The next morning Anmol came back and the County inspector was there an hour later to check the plans and work, which he approved. Then another 10 days waiting on Pepco to do the remote interconnect. April 1 we were getting all our power from the sun. I don't think anyone could get it done faster, better or at a lower price. I found everyone at GB to be the nicest, most professional people I have ever dealt with. They responded to my emails and calls within a couple of hours, if not immediately. Even with bad weather our first power bill was only $4.39. Thank you David Naylor

Happy with my system

Got a Silfap 400 14 panels 6.8kWh system with SolarEdge inverter installed by GreenBrilliance for my 1800 sq townhome. $25k system before the tax credit at 1.99%. I am very happy with the productions. Thank you Evan Miller.
