I had a solar system installed on my house in 2015 by SolarGains. They did great work at the time…read moreand it's been trouble free. I recently had an inverter fault and sent them an email asking to have a technician come out. Since it was 7 years later I really didn't even expect them to be in business let alone very responsive, but they happily proved me wrong by sending someone out the very next day to look at it! That's insanely good lifetime customer service that really deserves to be recognized. There aren't many companies out there providing that level of support, I would certainly go with them again for any project I had.

I talked to several companies about solar panel installation, and I selected Solar Gaines for the…read morefollowing reasons: -Solid parent company that is very competent and experienced in the solar industry -13.7 cent/kWh production guarantee, which is the highest I have seen (all companies I have read in their contracts are around 8.5 cent/kWh -Best price in terms of $/W I have encountered among companies -Included high quality inverter that can monitor on a per panel basis -Provided excellent details on how they manage repair work orders They are very flexible to work with in terms of scheduling for installation. The project manager I worked with is very knowledgeable and detailed. He discussed conduit runs to ensure it was aesthetically appealing and necessary components that need to be installed in order to pass county building codes. The project manager always returned my calls for any questions in a timely fashion, and their administrative team is very helpful for filing all necessary paperwork so that permits and tax incentives are filed in a timely fashion. Overall, Solar Gaines has been a great company to work with from project design, installation, to commissioning.

Working with these guys was easy, they went through all the options for our house and going solar…read moreso we could figure out which option made the most sense. There was no pressure so we could decide at our pace and they even helped us get a deal on a new roof at the same time. Have already referred friends to them and would use them again in the future.

I had a great experience with Lumina Solar when one of the inverters for my solar panels on the…read moreroof needed to be replaced. Their team was very responsive, scheduled the service quickly, and the crew showed up right on time. The replacement went smoothly and was completed much faster than I expected. The technicians were professional, efficient, and respectful of my property. I also have their SolarInsure 30-year warranty, which I highly recommend to anyone installing solar with them. Because of that coverage, the inverter replacement was fully covered and I didn't have to pay anything out of pocket. It made the whole process completely stress-free. Really appreciate the prompt service and hassle-free support--highly recommend Lumina Solar!

AVOID AT ALL COSTS - I am a real-estate investor and multiple homes owner, and all of the…read moreproperties I work with have solar panels. I am not new to the process, experience, or services rendered when it comes to solar panels. Working with this company has been the worst experience I have had to deal with, ever. They don't understand basic transactions with the electric company; they don't know how to smoothly transfer ownership from one party to another during a sales process; and to top it all off, they work extremely slow and are horrible with communication with their customers leaving you wondering if you are just stuck out of luck because they are "ghosting" you. Please, before deciding to work with them reach out to me and learn about my experience with them compared to other solar companies in the DMV area. I will be happy to take the time to save others from this headache.

I hired Solar-Verse to handle my solar installation. Their main sales pitch was that they would…read moretake care of all the paperwork for the Maryland government incentives.

Our 28 solar panels were installed last May and BGE finalized the installation in June. The system…read morewas originally sized to cover ~95% of our electric use. We opted for the micro-inverters so we can see how much power each of the panels is producing as well as the cumulative total. In 9 months we've accrued over 7 MWhrs of energy, even with our non-optimal orientation. The tax incentives paid for ~1/3 of the system. In addition to the savings on our electric bill, we receive about $960 from SRECs, green energy credits, a year. Plus there's a large boost in our home's equity. The sales and installation crew were the best! We're extremely happy with the whole package!

If you work full time and have a family, I would definitely recommend Celestial Solar…read more Choosing Celestial Solar has been one of the best decisions that we have made so far for our new home. As a family of 4 with 2 full-time working parents and 2 babies under two, Celestial Solar's support was nothing short of amazing for us. Jim and team are a good mix of professional and knowledgeable, and have been (and still are) genuinely nice to me and my family. They understand the complex nature of adding solar panels to your home and provide accurate estimates, recommend the best tech for your situation, walk you through the entire process, and have an awesome installation team who were efficient and installed everything without any hiccups. The extra support they also provide by completing permit paper work and communication on your behalf, mixed with the professional, yet fun, installation workers that my kids really liked, made this experience great for me and my family. We are now a few months into running our system and we have been overproducing energy, while Jim and team still keep in contact to make sure that everything is running smoothly.

Very easy to work with, Jim (the owner) was very easy to work with and plan with. Answered all of…read moreour questions and was very prompt with responses whenever a new one popped up. Gave us honest opinions on panel quality, recommendations, and laid out work expectations given their experiences working with the utilities. Installation was completed across 2 days due to the # of panels, they were very courteous, prompt, and efficient in getting the work done. We didn't have to hound Pepco or do anything additional, Jim handled it all for us. Our production for March 2026 was 1.3 MWh, electric bill was $8.94 (for cost of connecting to the grid). If you are considering solar, definitely give Celestial a call!

Sales: Our rep Greg was great to work with. Very responsive, knowledgeable, and we never felt…read morerushed or pushed into anything. We got panels installed in fall 2025 and got the system turned on in January. Greg answered a million questions and has continued to be our liaison and advocate. They under promised our production and have over delivered on our pepco savings. However, our roof was in rough shape but instead of letting us know that we shouldn't get panels before fixing the roof they said it would be fine and when we replace the roof in ten years they will remove and reinstall the panels for free under warranty. So after some big rains we realized we had roof leaks. Now the leaks were not coming in directly where they installed the panels, just close by. Our roof never had issues before, but with a bunch of guys climbing and hammering into it, there was bound to be issues. Without going into excruciating detail, the sales team has been great but the customer service from the company is lacking unless you get harsh with them. Having to wait 4 months to get panels reinstalled after getting a new roof, the techs not labeling the electrical so reinstall did not go smoothly, and two electrician visits because the first one didn't connect all the panels did not leave us impressed with the service. Finally all is resolved, but it's been a roller coaster. After everything my main takeaway is to make sure your roof is in really good shape before installing solar.
