Abstract :
This paper reveals effect of variation of natural and forced convection heat losses on performance of prototype parabolic dish collector with black nickel chrome coated receiver. In general, concentrated solar collectors have high efficiency as compared to flat plate and parabolic trough type solar collectors. Therefore for water heating application high efficiency can be achieved. Design of solar parabolic dish collector consists of truncated cone shaped helical coiled receiver made up of copper at focal point. This prototype was evaluated for its performance during month of April and May 2010.
