Kolektor Surya Prismatik

Abstract

Solar collector is the essential item of equipment which transforms solar radiation energy to some other useful energy form, for example as the water heater. One of the shape solar collector, is prismatic which have ability to receive solar radiation intensity from all the sun's position, so that using solar energy as water heater can more effective. Solar collector can absorb solar radiation intensity and convert it to useful calor for heating the water inside the pipes of the collector, so the temperature of the water is rise and natural convection is happen by the basic of thermosiphon because effect of mass density fluid difference. From the experiment is found the best position to locate the collector which can produce optimal efficiency are 15 degrre from east to north
