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."

Solar Panels questions, answered by experts

The average-sized home in the U.S.—around 2,500 square feet—will require between 15 and 34 solar panels to power the whole home. The specific number, however, will have less to do with home size and more to do with how much energy you use each year and the amount of sunlight in your region.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.

Solar batteries can be a great investment to help maximize your solar savings and make your system and home more valuable, but they’re most beneficial to customers who don’t have access to net metering. If your state or energy provider doesn’t provide net metering, batteries can be a great way to offset consumption even when your panels aren’t producing power. They also come with the added benefit of providing electricity through blackouts, so they’re valuable in areas prone to severe weather that could cause frequent blackouts. Your installer can help you decide if batteries are worthwhile.

Yes, you should tell your home insurance company about your solar panels. Even if you believe they’re covered by your existing policy, installing a solar panel system is a significant change to your home. This can affect coverage and premiums. By discussing your new solar panel installation with your insurance provider, you can be sure you have enough coverage and that the policy completely covers the panels against damage.

Solar panels have a life span between 10 and 40 years, depending on the type of panel. For example, monocrystalline panels can last up to 40 years, while thin-film ones only last between 10 and 20 years. The longevity also comes down to keeping up with solar panel repairs and their related costs .
