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

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

The best way to save money on solar panels is to take advantage of federal and state solar incentives. For example, the solar investment tax credit (ITC) offered by the federal government can save 30% of your total—if you can take the entire credit, which is based on income taxes owed—or an average of around $9,000. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for state and local incentives that could save you even more.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.

There are a few qualifying questions you should ask a local solar panel company before hiring them:

  • Will you handle permits for the installation?

  • Does your total price include the equipment and labor?

  • How long do you expect the installation process to take?

  • What kind of workmanship warranty do you include with your installations?

  • Who should I contact if I have a problem with my system after installation?

  • Do you install the panels or outsource the work to third parties?

  • Will you file for solar incentives for me?
