125 NEC code requirements for a shut-off, and more efficiencies and reliability of <br />126 micro inverters of low voltage; and risks for snow covered panels and subsequent <br />127 low output, with the dark panel color attracting the sun and melting snow to bring <br />128 them up to full production in short periods of time; with three months of each year <br />129 considered a "write off' due to the location of the sun, even though Minnesota <br />130 works quite well for solar power. <br />131 <br />132 Further discussion included which option was better: going through the lottery <br />133 system with only one out of four applications selected on average; or a straight <br />134 loan from the SPPA for a two page application fo r PACE financing. <br />135 <br />136 Mr. Kampmeyer advised that of the 44 applications they submitted last year, 22 <br />137 were approved, which was higher than normal; with the City of Golden Valley <br />138 submitting 8-10 applications and four approved; while other communities <br />139 receiving no approvals. Mr. Kampmeyer advised that the lottery system received <br />140 300 applications in 2014 with 106 of varying sizes selected. <br />141 <br />142 At the request of Chair Stenlund, Mr. ye vised that aisles for access of <br />143 other equipment on the roof were provi pical 40 K system taking up <br />144 4,000 square feet in one open area. <br />145 <br />146 Mr. Schwartz noted that the City had a number o uildings just on the city <br />147 campus with roofs of varying sizes, displayed by map (e.g. new fire station, <br />148 skating center, city hall, public works building, and police station) providing <br />149 campus solar rooftop space. Mr. Schwartz questioned if a Made in Minnesota 40 <br />150 K project was pursued, would it prohibit another type of project on another city <br />151 facility's roof %i*ceth 't has up to six meters available at this time. <br />152 <br />153 r. Weir responded that it would not, with plenty of rooftop available; and noted <br />154 4the desire to install solar arrays on newer rooftops, but some facilities of the size <br />155 that could allow both a 40K and a 100 K system on the same rooftop; and with six <br />156 meters available, should provide more flexibility as well. <br />157 <br />158 Commissioners and/or staff sought additional information, with Sundial <br />159 representatives offering to provide that information to staff for dissemination: <br />160 which portions of the solar systems are recyclable (e.g. racking and rails made of <br />161 aluminum an silicon); and whether one 40K per meter would impact any other <br />162 meters, or simply mean adding another meter. <br />163 <br />164 At the request of Member Gjerdingen, Mr. Kampmeyer advised that maintenance <br />165 and operational responsibilities would be outlined and built into a contract. <br />166 <br />167 Mr. Kampmeyer reviewed typical moving of panels and the system if required <br />168 with any unforeseen repairs for a roof, with the panels coming apart and picked <br />169 up for assembly or disassembly as the case may be; with the preference for <br />170 installations on rooftops that are less than 5-7 years old to avoid that potential. <br />Page 4 of 11 <br />
