Residential Solar Panels

Your solar panels will require permits and inspections in order to ensure that they are safe for use. We encourage you to review our solar panel requirements before applying for a permit.

Note: Maryland state government and the federal government have renewable energy incentive programs, including tax credits and rebates, which you may be able to take advantage of. Please see the Maryland Energy Administration – Residential website and the – Tax Credits, Rebates & Savings website for more information.

Permits Required

Your solar panel(s) will require a building permit and an electrical permit. Prior to the issuance of the building permit, an electrical permit must be filed using the building permit number. If the solar panel(s) will power a hot water heater, a plumbing permit will also be required prior to the issuance of the building permit.

Permit Process

Many factors affect the speed with which your application(s) are approved. For best results, it is critical that you carefully review your application and design documents prior to submission to ensure that all necessary documents are included and that the design is compliant with the county code. Normally, permits can be issued within 5-7 business days if the application is complete, accurate, and code-compliant.

Construction Document Requirements

Submitted documents must contain sufficient information for the plan reviewer to be able to review the proposed construction.

If your solar panel(s) will be attached to the roof of a structure, please provide:

  • ___ Two (2) complete sets of detailed construction plans – drawn to scale – to include:
    • ___ Manufacturer’s installation specifications

If your solar panel(s) will be free-standing, please provide the two (2) sets of detailed construction plans noted above, plus:

    • ___ Measurements from the proposed solar panel(s) to existing/proposed well and/or septic area
    • ___ Road name

Upon inspection, your solar panel(s) will need to be certified by a licensed Master Electrician as having been installed per manufacturer’s guidelines, product specifications, and all articles of the International Building Code (IBC) and National Electrical Code (NEC) as adopted in Carroll County.
