Select EPUD shade form

Use the graphic links on this page to select a shade form customized for the Emerald Peoples Utility District. Choose a form with the appropriate tilt and orientation for your purposes, then pick either the rectangular or polar style chart. The leftmost table column contains the range of applicable PV array tilts (0 to 90 degrees), and the top table row contains the range of applicable array orientations (South is 180 degrees) corresponding to the shade forms available at the intersecting rows and columns. More information about the sun path charts that form the basis of these shade forms is available here.
