Abstract
Shade mitigation systems and devices to mitigate adverse effects of shade on a primary photovoltaic cell powering a load via an output terminal. The shade mitigation devices include a relay switch and a secondary photovoltaic cell. The relay switch selectively completes a circuit between the primary photovoltaic cell and the load when energized. The secondary photovoltaic cell is electrically coupled to the relay switch and is mounted in a position to monitor illumination on the primary photovoltaic cell. The secondary photovoltaic cell energizes the relay switch to selectively complete the circuit between the primary photovoltaic cell and the load when the secondary photovoltaic cell is illuminated by at least a threshold illumination. The secondary photovoltaic cell stops energizing the relay switch to selectively open the circuit between the primary photovoltaic cell and the load when the secondary photovoltaic cell is shaded sufficiently to illuminate it below the threshold illumination.
