By actively rotating your panels from East to West to follow the sun's daily arc, they squeeze significantly more yield out of the exact same equipment. . elastic instabilitiesof single-axis solar PV trackers are provided. Sectional and aeroelastic model tests are used to discern stiffness-driven from damping-driven instabilities. This efficiency boost is why trackers are now the default for utility-scale solar—data from Lawrence Berkeley National Lab indicates they are now. . Single axis tracking simply means there is one axis of rotation. The axis of rotation is horizontal, usually orientated North-South with the modules facing toward. . Horizontal uniaxial photovoltaic panel orientation does something remarkably similar for solar arrays. Conversely, when it moves around two axes. .
