Abstract The main goal of this work is to utilize the green house gas (mixture consisting of carbon dioxide, methane and nitrous oxide in the mole ratio of 1: 3: 1) filled conventional solar collector panel for natural circulation system (NCS) and wind assisted circulation system (WACS) to study the boosting effect in the performance of solar collector panel of both the systems. From the experimental results, the daily average system efficiency increased up to 8.14% and 8.38% for NCS and WACS. It was observed that the hourly average efficiency varies in line with the variation of incident solar radiation and was found to increase with increase in circulation rate of water across the collector. It the available wind velocity is sufficient in the location, WACS with gas filled in the collector panel under normal atmospheric pressure (WACS-GAS) would suitably replace the NCS and WACS as it can function without electricity and can be installed in remote areas where electric supply is on high demand.
