The efficiency at which Concentrated Solar Power (CSP) and concentrator photovoltaic (CPV) systems can generate electricity is directly dependent on the capacity of a solar tracker to attain the most precise alignment with the sun’s positional shifts, enabling for sunlight to be accurately focused. Sensors play a key role by providing the necessary feedback as to whether or not correct positioning is achieved. If a system is slightly off-target, the sensor will provide the critical data that is needed to get back on track with the sun’s cycle and the perfect rotation. As such, the choice in a sensor solution is an extremely important consideration.
