angle of the panel is its +/- angle relative to true south (0°). Tilt angle is the angle the panel is tilted from flat. Finally, the reflectance of the ground surrounding the solar panels must be taken into account because sunlight can reflect off of a surface onto a tilted panel and alter the total solar irradiance collected. The local and solar ................
