Compare test of solar hot water systems from image, and select an angle for a given application is very important. Outdoor test is still widely used for that purpose and a number of standards have been developed. Solar domestic hot water systems for the focus at home this year (TSDHWS). Extensive literature reviews have been carried out through development and implementation of these standards. The test standards can be seen, in a relative comparative assessment of common test equipment has not been reported. In this report, the qualitative comparison of these procedures has been rendered. Solar-only standard is broad evaluation tests to examine their advantages and limitations. It has been found that the operating conditions for some of the standards are strict and requires longer testing time. A new, comprehensive, and complete test program development. Three parameters, namely, (I) the characteristics of system efficiency (ii) solar energy loss coefficient and (iii) explains TSDHWS all day night loss coefficient. The first two parameters are reflected in energy harvesting stage performance, and a third said energy retention capacity. Seven-hour testing period, so testing may be in India all Web sites. Sampling rate of 1.5 hours, find sufficient measurements and data collection. Test results are repeatable and not sensitive to measurement error. A TSDHWS in the performance of a test place for 10 days can be represented in any test to predict its performance in any month of the year. Therefore, the new method is simple and can be applied to a variety of TSDHWS. It can be considered for adoption as a standard procedure.
