SUBJECT: Combined Review for Gunnala Residence: 6161 N. 44th Place. Application for roof mounted solar panels.
The owner of the property located at 6161 N. 44th Place submitted an application to add roof mounted solar panels on top of the residence.
Solar Panels
The home was constructed in 2000 and the applicant is proposing to add 8 roof mounted solar panel arrays with 66 total modules. The panels are rectilinear in shape and a maximum of 1’-4” in height and will be concealed by existing roof parapets ranging from 2 feet to 3 feet in height.
The solar panels will have black frames and the racking system will also be black or painted with a color that has a light reflective value (LRV) of 38 or less. The solar system inverters, photovoltaic meter and electrical disconnects will be placed on the outside of the house and will be painted to match the house.
