The Milwaukee Historic Preservation Commission voted to hold a certificate of appropriateness application for rooftop solar panels at 2591 North Summit Avenue (Northpointe North Historic District) after an extended discussion about visibility standards, energy production and economic viability.
Staff presented mock-ups showing the panels on the front (east) elevation and advised that the application could not be approved at the staff level because of front-facing visibility. The applicant’s contractor provided a mock-up indicating panels on the east slope would yield substantially greater production than the rear (west) slope; the contractor’s estimate suggested moving the array to the rear would reduce production by roughly half and could be economically unviable, according to the applicant.
Commissioners reiterated National Park Service guidance the commission uses as a benchmark — preferring nonvisibility on primary elevations where possible — and said the commission has previously worked with applicants to locate arrays to less-visible roof planes. Several commissioners asked the applicant to supply three contractor quotes and technical information about expected annual production and lifecycle economics before the commission makes a final decision.
The commission’s chair moved to hold the item for one month to allow the applicant to provide contractor documentation and, if possible, third-party production figures; the motion carried. Staff said if the applicant moves panels to a rear roof that meets staff-level visibility guidelines, staff can approve the COA administratively.
The discussion emphasized the commission's repeated approach: permitting solar energy systems on rear or less-visible slopes where feasible while balancing renewable-energy goals against preservation of primary facades.
Clarifying details
- Property: August Rome House (Tudor Revival, circa 1909) at 2591 North Summit Avenue; corner lot with visibility from multiple public ways.
- Applicant position: Contractor mock-up indicated east/front elevation yield is materially higher than rear/west placement; applicant stated rear placement might be economically unviable.
- Commission direction: Applicant to provide three contractor quotes and objective production/economic data for commission consideration; item continued to next regular meeting.
No final determination was recorded; the item will return after the applicant supplies the requested technical documentation.
