Permits and Variances for Solar Panels, Calculation of Impervious Cover

In May 2012, Maryland passed legislation aimed at promoting the adoption of solar energy by streamlining the permitting process and incentivizing solar installations. The law mandates that any calculations of “impervious surface” required for permits or variances related to zoning, construction, or stormwater management should only take into account the foundation or base supporting solar panels. This provision applies across the state, including in charter counties and Baltimore City, with the exception of specific “critical areas” such as the Chesapeake Bay Critical Area and the Coastal Bays Critical Area.

By focusing solely on the foundation or base of solar panels when determining impervious surface, the legislation effectively reduces the bureaucratic hurdles and costs associated with installing solar energy systems. This move is significant as it encourages individuals, businesses, and communities to embrace solar technology by removing unnecessary barriers to its implementation.

It’s worth noting that while the law does not explicitly define the term “solar panel,” it is understood to encompass both solar photovoltaic (PV) and solar thermal panels. This broad interpretation ensures that various types of solar energy systems can benefit from the incentive, further advancing Maryland’s renewable energy goals.
