<p>A solar trajectory projector is movable along an azimuth or zenith axis relative to the trajectory of the sun. A solar collector with a system of mirrors, a light guide, and lenses collimates the light and concentrates the light trajectory on a single point. A cloud sensor has photoelectric cells, an ammeter, and a programmable logic control that cuts the power supply to the concentrator upon detected presence of clouds.</p> |
