Impact of Using Tracking Surfaces on Necessary Solar Radiation Collecting Area in Stock Raising Applications

We tackle the impact of using steerablesolar collectors on the collecting surface in stockraising applications. The comparison is made withresults obtained in a previous study based on fixedsolar collectors. Tracking surfaces with fixed east-westaxes and surfaces that can be rotated about twoorthogonal axes are considered. Insolations on fixedand movable surfaces are calculated from hourlyglobal and diffuse irradiation data. The reduction inthe necessary collecting surface in order to achievesimilar heat quantities is evaluated. The reportedresults apply to the region of Timisoara, Romania,situated on the 45 deg. northern parallel. Thecalculation is based on recent local measurements ofthe hourly irradiance.
