Dual axis solar tracking system for a parabolic dish CPU water heater

Abstract The solar parabolic dish water heater is highly efficient but has limited hours of work only when sunlight perpendicular to its surface. Therefore, this aims continue the in daytime using a dual tracking system, depending on geographic location system (longitude and latitude angles) C # programming language. To verify effect dual-axis current study considered two types dishes, first was fixed, second rotating (by system). It observed that temperature at outlet type 22% higher than for fixed type; means proposed improved heat exchanger. highest value about 51.4ffiC exchanger 1:00 pm, while recorded 46.1ffiC. energy gained from heating pm both types, which 76.9 W 54.7 type. also type, most losses occurred during daytime, tracer useful sunny working radiation intensity.
