TO: Hillside Building Committee
DATE: November 8, 2017
FROM: Paul Mood, P.E., Town Engineer
SUBJECT: Combined Review for Bishop Residence: 7154 N. Hillside Drive. Application for roof mounted solar panels.
The owner of the property located at 7154 N. Hillside Drive submitted an application to add roof mounted solar panels on top of the house.
Solar Panels
The home was constructed in 1994 and the applicant is proposing to add 4 solar panel modules/arrays on top of the house. The panels are rectilinear in shape and a maximum of 1’-6” in height and will be concealed by an existing 1’-6” roof parapet.
The solar panels will have black frames and the racking system is currently shown as bare metal. It is staff’s recommendation that the Hillside Committee address the bare metal framing and stipulate that the framing be black. It also appears that the existing flat roof color does not meet the maximum LRV of 38. The Hillside Committee may want to address this issue.
The solar system inverters will be located inside the garage. The photovoltaic meter and electrical disconnects will be placed on the side of the house. The photovoltaic meter is shown to be painted the same color as the house. It is staff’s recommendation that the Hillside Committee stipulate that the electrical disconnects be painted the same color as the house. The plans show the proposed color as adobe with a LRV of 50 which exceeds the maximum LRV of 38. The Hillside Committee may treat the electrical equipment as accents.
