Item 6D13 SOUTHLAI<,,E CITY OF Department of Planning & Development Services STAFF REPORT June 1, 2011 CASE NO: ZA11 -021 PROJECT: Carlson Residence Solar Energy System EXECUTIVE SUMMARY: On behalf of David Carlson, Stark Service Co. is requesting approval of a Specific Use Permit for a Solar Energy System on approximately 0.46 acres located at 900 Ownby Lane. SPIN #7 DETAILS: Stark Service Co. is requesting approval for a Solar Energy System consisting of 4 solar energy panels approximately 56 square feet in area combined to form a 760 watt photovoltaic system in conjunction with the installation of a new high- efficiency solar -ready air conditioning system. The panels are proposed to be installed on the roof of the existing residence on the property. Specifications of the photovoltaic panels have been provided under Attachment "C of the staff report. ACTION NEEDED: 1) Conduct Public Hearing 2) Consider Specific Use Permit for a Solar Energy System Approval Request ATTACHMENTS: (A) (B) (C) (D) (E) (F) STAFF CONTACT: Background Information Vicinity Map Plans and Support Information Surrounding Property Owners Map Surrounding Property Owners Responses Resolution No. 11 -027 Dennis Killough (817) 748 -8072 Daniel Cortez (817) 748 -8070 Case No. ZA11 -021 BACKGROUND INFORMATION OWNER: APPLICANT: PROPERTY SITUATION: LEGAL DESCRIPTION: LAND USE CATEGORY: CURRENT ZONING: STRATEGIC LINK: TRANSPORTATION ASSESSMENT: TREE PRESERVATION: PLANNING & ZONING COMMISSION: STAFF COMMENTS: David Carlson Stark Service Co. 900 Ownby Ln. Lot 10, Block 5, Southview Phase II Medium Density Residential "SF -20A" Single Family Residential Zoning District This request meets Objective B6 of the City of Southlake's Strategy Map; Optimize the use of Technology. This request does not affect traffic on or around the property. Since the solar panels are being requested to be installed on the roof of the existing home, no trees will be affected by the request. Approved (4 -0) May 5, 2011 subject to staff's report dated April 29, 2011. Due to the limited nature and scope of the request, no review has been provided.

TX 76053 Case No. Attachment C ZA11 -021 Page 1 Designed for Maximum Reliability and Systematic Installation Solar systems must last decades in the harsh environment of your roof To ensure these systems last, meticulous engineering design was applied to build the next generation in solar system that eliminates exposure of weather sensitive components Andalay is designed for primary assembly at our factory, not at your home like ordinary solar systems. The result is an integrated solar system thatwill provide decades of reliable solar power performance. Case No. ZA11 -021 With "Good Looks" to Match Andalay's Meticulous Design I n addition to Andalay providing a more reliable system that delivers decades of solar power performance, it also delivers a cleaner and more attractive look With its slimmer panels, invisible electrical cabling and hidden mounting system, Andalaytakes less room Mile blending into your roof like a skylight Attachment C Page 2 I I/ / M olo TM A whole new look to solar power Andalay is an integrated solar power system Built -in Reliability & Safety Built -in electrical and ground connectors can't loosen or be installed incorrectly. Shorter wire lengths are less likely to fail by pinching or abrading. 70% fewer roof assembled parts means a longer lasting system. 25% fewer roof attachment points means greater roof integrity. Grounding process can't skip panels, connectors won't wear or corrode, for maximum longterm safety. 4 High Performance Latest generation monocrystalline cell technology. Output tolerance ofjust 3% meansthe promised power is delivered. Lighter weight and less space between panels so more can fit on.a roof. Lower electrical resistance losses due to shorter wire lengths. d Convenience and Safety for Customer and Installer Fully compliant with UL 1703 solar test and NEC safety requirements. Faster installation time means less interruption for customer. A lighter system that requires a single hand tool to install makes it safer for the installer. Easier to disassemble and reassemble in - futureif needed- Great Aesthetics No external racks or dangling wires for a clean., uncluttered look. No gaps between panels for a contiguous, smooth appearance. Panels and all hardware are flat black —they look like skylights!
