In an experiment to find a performance, a smooth sheet of solar hot water system, this. Faculty who have made the trial operation for a period of 5 days from the day of 19, 20, 21, 22 and 24 of the Finance Committee who may have made 2558 (2015) equipment produced by solar radiation, hot for a trial size of 1 × 2 solar square meters. The number 2 spot RT panel Panel Sunday, it must be installed in areas where the sun shines and there is nothing obscure the Sun, step into mission preparation have made to try to find a flow rate of the water. In the system to find an appropriate flow rate and temperature, is the best because the water flow rate will be in effect through the temperature of the water in the system for water flow rate at 0.05, 0.07, 0.11, 0.09 and 0.13 L/s "," "," ^ ", 2" in the experiment to find the flow rate L/s 0.05 "," "," ^ ", 2", it can make the water temperature at the maximum of 7 available.3.5C, The flow rate in L/s "" 0.07 "," ^ ", 2", it can make the water temperature up. 7 C, . The flow rate of 0.09 L/s "," "," ^ ", 2", it can make the temperature of the water used at the maximum rate of 70.4 C, flowing at 0.11 L/s "," "," ^ ", 2", it can make the water temperature at the maximum available, 68.7 C. The flow rate in L/s "" 0.13 "" ^ 2 "," the temperature of the water up. 68.3 C flow rate that best suits this system is 0.05 L/s "," "," ^ ", 2", because the temperature of the water can be made available. C more than 73.5, the highest value flow rate etc. Faculty Manager, flow rate at 0.05 L/s "," "," ^ ", 2" as the appropriate flow rate values of the system in a trial and in trial preparation team have conducted experiments on 19, 20, 21, 22, and 08.00-17.00 hours p.m. May 24, 2015. From experiments made to determine performance for maximum use temperature is the maximum temperature of the water running May 19, 2015 is 73.3 C at 14.50 hrs at flow rate L/s 0.05 "," "," ^ ",". 671.31 ", k is the average solar/" "^ m", "2", it can calculate the efficiency of a solar day at water temperature up 41.57% and is made to calculate the performance of the average solar day by taking the entire 5 to calculate the performance options to find solar. The results from the calculation of the efficiency of the solar was 38.53%
