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

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Solar shingles last between 20 and 30 years, which is about as long as solar panels and standard asphalt shingles last. Their exact life span depends on the manufacturer and the quality of installation. You can increase the longevity of your solar shingles by conducting regular inspections and maintenance and making any necessary repairs as quickly as possible.

Most solar panels last 25 to 30 years and have a warranty to match. Over time, you’ll see a diminishing electrical output. This is normal wear, but certain things can hasten solar degradation. These include heavy rainfall, high temperatures, constant humidity that corrodes the frame, and cracks or chips in the glass.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.

You’ll need to make sure you have a big enough solar panel to meet your well pump’s power demands, but you can use solar power to fully operate your well pump. It’s also a good idea to have battery storage to hold the solar power so you can still use your well pump after dark.
