Description: Biomass resource assessment by county in the United States. Feedstock categories include crop residues; forest residues; primary and secondary mill residues; urban wood waste; and methane emissions from manure management, landfills, and domestic wastewater treatment. Additional information is available at <http://www.nrel.gov/gis/biomass.html>. For more information on the data development, please refer to <http://www.nrel.gov/docs/fy06osti/39181.pdf>. Although, the document contains the methodology for the development of an older assessment, the information is applicable to this assessment as well. The difference is only in the data's time period.

Name: US Photovoltaic Solar Resources (kWh/m/day) (NREL)
Display Field: AREA
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This data (units kWh/m2 per day) provides monthly average daily total solar resource information on grid cells of approximately 40 km by 40 km in size. The insolation values represent the resource available to a flat plate collector, such as a photovoltaic panel, oriented due south at an angle from horizontal equal to the latitude of the collector location. This is typical practice for PV system installation, although other orientations are also used.
