COMMERCIAL SOLAR CASE STUDIES

Advanced Solar is a full-service commercial solar EPC firm serving Maryland and the District of Columbia. Our sales, engineering, roofing, and installation teams are all in-house, ensuring that every step of every project meets our high standards.

Churches, nonprofits, municipalities and commercial property owners can often get a new roof and a lower electric bill with no capital outlay and no debt.

Advanced Solar has installed more than 4,000 systems and manages O&M on more than 4,000 DC and MD sites. Our grant team has secured more than $2 million in Maryland Energy Administration funding for commercial projects — plus federal REAP awards and DCSEU Solar For All support.

We have developed 3 MW of commercial solar projects with support from Maryland Energy Administration Grant Programs and 1.477 MW of commercial solar Community Renewable Energy Facilities projects in DC with the support of DCSEU, including 762.4 kW built in 2026.

DC's solar incentives make it possible for many property owners in DC and nearby MD to get free or discounted power without purchasing a system. These same incentives make system ownership an attractive option too.

DC's valuable Solar Renewable Energy Credits - which are also available in nearby parts of MD, make "zero-cent power purchase agreements" possible. They can also add 100s of thousands of dollars to the economic benefits of purchasing solar arrays.

Our investors will pay system purchase, installation, and monitoring costs in exchange for DC/MD incentives and tax credits. You get all the energy the system produces.

You can see more images of some of our recent commercial solar projects at the bottom of the page.

These commercial solar case studies show that whether you choose to own a system or get discounted or free power, Advanced Solar can deliver significant economic benefits.

Projected results. Actual savings vary by site, system and utility rates.

Westmoreland paid nothing for the system or the roof replacement, and locked in its electric rate for the next 20 years. Pepco’s rate is already 160% higher than the church’s solar rate — and Pepco’s rates keep going up. Developed by Nick Hayes.
