"Don’t use the plumbing! Called to have Kohler toilet tank plunger repaired. Whole installation is $20. Labor is an hour at $80 so the price is $150, at most. No, they charged $450–BS! These guys are a scam. No prices and I told them to have the repair person call me before arriving. No call, no prices. And, then the repair person has the stones to tell me that everyone overcharges!! Let’s start with not using Beacon!!!"

We are a full service, owner operated solar company headquartered in Eldersburg, Maryland. We design and install custom solar electric and back up battery systems for homes and businesses in Frederick, Carroll, Baltimore, Montgomery, Howard, Prince George's, Anne Arundel, and Washington counties. We do not provide service to existing systems that were installed by another company.
"We had Celestial Solar complete the installation of our solar unit at the end of May 2025. The whole team did an amazing job from start to finish - design, county approvals, utility company, SRECS, installation, monitoring system, and even helped me with a state grant program. Jim (owner) was always available and the whole team was super helpful and communicative. We had ZERO issues - so smooth. Our system was designed for 100% offset and we have out produced usage every day since install. The panels look great. We couldn't be happier with our choice. I received over ten different estimates from the leading solar companies and not only was Celestial competitive with the most competitive prices, but offered higher quality materials and completes all the work in house. Highly recommend."

"Hot water issue. Technician gave estimate for hot water tank replacement of 8 year old lightly used tankless. In light of the phenomenol price tag, did some homework. Hit the reset button. Fixed. Hmmmm. Maybe it was the tankless that confused him. Really glad it was a free estimate (unlike Len's who charged me $315 and didn't fix it)."
