2. INTRODUCTION: Focusing collector is a device to collect solar energy with high intensity of solar radiation on the energy absorbing surface. A focusing collector is a special form of flat collector modified by introducing a reflecting ( or refracting) surface (concentrator) between the solar radiations and the absorber. Focusing collectors can have radiation increases from …

Solar collectors are heat exchangers. Solar collectors transform solar radiation into heat and transfer that heat to a medium (water, solar fluid, or air). Then solar heat can be used for heating water, to heating or cooling systems, or for heating swimming pools. They can be classified in two groups: 1. Flat-plate collectors, 2.
