79 power savings through less consumption were anticipated due to heat from the roof 80 over the ice surface, a long time issue experienced during a portion of the year in 81 cooling the indoor ice arena space. Mr. Culver opined that the solar panels would 82 absorb some heat, helping with that energy loss. 83 84 Based on the long-term analysis provided by Sundial, Mr. Culver reviewed 85 estimated operation and maintenance costs for the City at year 6 of approximately 86 $7,500; but advised additional information was needed for staff's review and 87 analysis on what those actual maintenance costs assumed, or what components they 88 included; and figuring in the replacement of the eJ�vement system in year thirty as that 89 is incorporated into the City's long-term capital,,,,1 program (CIP). As 90 with any asset the City owns, Mr. Culver noted that, assuming thirty-year life for 91 the panels, replacement costs would need to be estimated at the end of the life cycle. 92 93 In conclusion, Mr. Culver advised that staff was recommending entering into a 94 Letter of Intent with Sundial Solar initiating the process of negotiating more final 95 and specific terms for Power Purchase Agreement. Mr. Culver suggested staff 96 returning to the PWETC at their August meetin h those final provisions, and 97 subsequent recommend a n to the City Coun for their fin,pproval in 98 September of 2015. ""°��iii�lllllll m, 99 100 At the request of Member Leigler, r. Culver clarified that the previous Letter of 101 Intent entered into with the Metropolitan Council was still being pursued, and was 102 specific to community garden shares, and would still be needed since the City 103 consumes more power than could be generated on, city campus roofs, and if 104 pursued, would allow the City to obt ' energy offset from that community solar 105 garden system,1,,,,11ii1 well. 106 107 7thequest of Me er Le z, Mr. Cu advised that staff continued to check 108 nces provid art of Sundial Solar's proposal; and those reviewed to - 109 proven favorab r. Culver further clarified that the Letter of Intent 110 would be nonbinding, an teps in the analysis and review process would be 111 completed before entering int ower Purchase Agreement. Member Lenz noted 112 that, since this is new technology, there was no long-term history available. 113 114 At the concerns expressed by Member Wozniak regarding losses from severe 115 weather, Vice Chair Cihacek noted there would be a clause provided in the final 116 Agreement addressing natural disaster costs and remedies; and noted that individual 117 panels could be removed and replaced if the entire system wasn't damaged. 118 119 Again, as with any other City asset, Mr. Culver noted the City's insurance would 120 address losses as part of the City's overall insurance liability costs and provisions. 121 122 Member Stenlund asked if both panel systems had their own inverters, or each panel 123 had individual inverters; recommending that the City pursue individual inverters Page 3 of 5
