Solar irradiance measurements by means of optical fibers and silicon detectors.
An experimental system has been constructed for the continuous measurement of solar irradiance using silicon diode detectors not directly exposed to solar radiation. The received incident solar radiation is conducted from the roof of the building to the detectors by an optical fiber. An electronic computer receives the signal and processes it, introducing the necessary corrections to calculate the total solar irradiance in W m(-2). The system measures with a proved accuracy to better than 3%.
