Panel Shading lets you optimize the geometry of rows of flat-plate solar collectors (PV or solar thermal) by visualizing on an annual basis how much the rows shade each other each hour of the day, each month of the year. The tool accepts a location and the dimensions of the panels and environment as inputs, and produces a chart depicting the degree to which the panels are shaded each hour. By adjusting the panel dimensions, tilt, and spacing, shading can be minimized during critical periods. Screen Shots
