SOLAR CONCENTRATOR GUIDANCE

In this work we discuss the control of a solar concentrator located at Temixco, Morelos, Mexico. This place accounts with the greatest constant illumination in Mexico. For the construction of the concentrator we use a recycled parabolic plate (NEC). This plate was totally covered with aluminum. Its opening diameter is of 332 cm, the focal length is of 83 cm and the opening angle is of 90deg. The geometry of the plate guarantees that the incident beams, will be collected at the focus. We obtain up to 2000degC of temperature concentration with this setup. In order to optimize the operation of the concentrator we use a control circuit designed to track the apparent sun position.
