Abstract
A solar sensor for the detection of the direction of incidence and the intensity of solar radiation comprises a housing () made of a plastic material that is permeable to at least some of the solar radiation, the housing () having a curved side () facing the incident solar radiation and the housing () optically acting as a lens and having an internal focal plane () defined by the lens characteristics thereof. At least two photosensors () are embedded in the plastic material of the housing (), each photosensor () having a sensor area () sensitive to at least the part of the radiation to which the plastic material is permeable, and the sensor areas () of the photosensors () being arranged in a substantially common plane () located in front of or behind the focal plane (), seen from side () facing the incident solar radiation. The direction of incidence of the solar radiation is determinable based on the intensities of the solar radiation received by the sensor areas () of the photosensors ().
