Integrated collector storage solar water heater with compound parabolic concentrator – development and progress

This paper presents up to date developments in integrated collector storage solar water heater (ICSSWH) using compound parabolic concentrator (CPC) collector. Performance of integrated compound parabolic concentrator storage solar water heater (ICPCSSWH) is affected by various parameters such as positioning and arrangements of water tanks, reflector types, absorber surfaces, glazing and other design parameters. The various designs of ICPCSSWHs and their performance analysis are reviewed. Recent developments in CPC based ICSSWH show a hopeful design to consume solar energy as a reliable heating source for water heating applications. But, by its collective collection and storage function undergoes significant thermal losses to ambient, particularly at non-collection periods.
