The aim of the study is to improve thermal performance of passive serpentine flat plate solar collectors using striped technique. Striped mechanism was applied on absorber plate so as to diminish thermal fusion in the plate and investigation enhancing practice of energy conversion from the collector units to the working fluid. Study was conducted or carried out using experimental testing. Demand of domestic hot water has mostly been filling with conventional flat plate solar collectors. Conventional solar collectors are relevant for high flow rate that requires high operational costs. In the past, serpentine solar collector was ignored due to large pumping requirements at higher flow rates. However at low flow rate, serpentine collector is more economical and efficient. Therefore, striped absorber plate of the serpentine solar collector in varoius modes were designed by Solid Work and CATIA. The effect of the configuration parameters of striped serpentine solar collector was investigated and good result was obtained. The analysis was done by decoupling the last striped from whole system. So that the result of the second stripe became inlet boundary condition for the last of four segments. For the collector mass flow rate of 0.00285kg/s and solar radiation of 650w/m2, temperature of absorber plate and water at collector exit became 353k and 336.9k respectively.
