Abstract

A CSP farm design and analysis using light, servo-controllable, rectangular mirror arrays as heliostats is presented. Performance of such a heliostat for CSP is analyzed for diurnal and seasonal variations. The equations to program the heliostat for sun tracking are derived and the effect of shadowing on the heliostat efficiency is quantified. The optimal heliostat design process for a CSP farm is presented. A horizontal as well as vertical farm layout are discussed and compared. It is shown that a CSP farm based on the heliostat design presented here can be robust, low-cost, flexible and scalable.
