<br />13 <br /> <br />Alternative Layout <br /> <br />An alternatfve, larger-sized system is proposed for a better system value. The array will sized to 53.12 kW DC / <br />39.9 kW AC and will be located on two roofs at the city hall, the south facing roof and the southeastern facing <br />roof. The southern facing roof is the optfmal one in terms of power productfon, and the maxi mum number of <br />panels that physically fit was placed here. The southeastern facing roof was determined to be the second-best <br />optfon, as it is larger in area and peaks higher off of the ground but does not face due south. This roof face <br />contains the remainder of the solar panels. <br />Trees are a bigger consideratfon on the southeastern roof. One tree in partfcular is currently growing directly <br />over the roof surface of the southeastern face and will cast substantfal shade onto the array. This report <br />assumes this tree will be trimmed. Panels were not placed on the lower most portfon of this ro of to mitfgate <br />some of the effects. If the city or it’s council cannot or does not want to trim this tree, Apadana will work with <br />the city to possibly relocate the most shaded modules or get rid of them and proportfonally reduce the cost of <br />the array. Another tree that will cast shade is found to the south of the southern facing roof. We simulate that <br />this tree will not cast as much shade, as the sun will be closer to directly over head when the shade from the <br />tree hits the roof surface. Other trees around the building may also cast more shade in the future as they grow <br />but this will depend on tree species. <br />Equipment for this system would use the same Znshine modules, SolarEdge inverters and racking as the main <br />proposed system. Disconnects and other related solar equipment would be upsized to handle the higher <br />current as necessary. Pricing and productfon are attached at the end of this report. <br />
