If you are concerned about getting solar installed in a DC Historical District, Advanced Solar is familiar with the codes and requirements and can design and install a Solar Photovoltaic System to power your home using the DC Free Solar Program, with the equipment invisible from the front of the house, as per most Historical District requirements.
The only component you will see is the AC disconnect switch as required by PEPCO, which dictates that the disconnect switch needs to be near the PEPCO meter with nothing mounted in front of the meter. Therefore, nothing can obscure the meter from view due to the need for PEPCO personnel to quickly find and disconnect power during service to their electrical system.
