For slope, rooftops with a no slope were calculated as “flat” rooftops, which have a slightly larger suitable minimum square foot area for installation than roofs with a pitch. For aspect, any rooftop area oriented northeast, north, or northwest were all considered not suitable (too few direct hours of sunlight). </LI></UL>Once analyzed, the resulting solar insolation raster was used to calculate total solar potential"Abbreviations:W - WattKW - KilowattMW - MegawattGW - GigawattWH - Watt HourKWH - Kilowatt HourMWH - Megawatt HourAttribute Information:SolGenWH: Solar generation potential (in Wh), accounting for a system panel efficiency of 13% and that the kWh generation to kW capacity ratio was 1300SystemCost: Estimated dollar value for system based on size, for Minnesota average per watt cost for solar panel & installation at $2.74; estimate assumed that only 75% of max system capacity was going to be installed per system, or for larger systems that economies of scale would provide per watt savingsCO2Avaoided_lbs: Estimated avoided CO2e emissions in lbs (from Xcel 2017 community energy reports, which estimates 802 lbs / MWh when solar replaces conventional grid)</DIV></DIV></DIV> Engineering Solar GPI Insolation Environmental Sustainability Enterprise Geodatabase Feature Class dataset Esri 9.0.0 0 Simple FALSE 0 TRUE FALSE ReACT_BuildingFootprints_Solar Feature Class 0 OBJECTID_12 OBJECTID_12 OID 4 10 0 Internal feature number.
