The USPVDB Viewer, created by the USGS Energy Resources Program, allows users to visualize, inspect, interact, and download the most current USPVDB through a dynamic web application. The United States Large-Scale Solar Photovoltaic Database (USPVDB) provides the locations and array boundaries of U. photovoltaic (PV) facilities with capacity of 1 megawatt or more. Use these SepiSolar solar and energy storage checklists to gather all the information needed for an accurate solar or energy storage design. ven to help assist you. Please ensure if the cross section is showing a Typical Cut Roof, That you also show measurements ' ' & 'E' on the diagram. This checklist covers property and planning details, roof and loft condition, orientation and shading, available roof area and obstructions, proposed panel layout and output, inverter placement and DC isolation, AC isolation and generation meter.
