Research of the cooperative pea.In this research study. The solar energy to the pavilion and northeastern purpose. To find the work efficiency of the power system of solar cells. The installation at the pavilion and northeastern Building engineering laboratory and industrial technology building 14 Sakon Nakhon is producing direct current size 280 watts used to load the light tube. LED Size 9 watts used 10 hours. Use DC water pump size 12 v. use 2 hours. Use alternating current system 220 v. 50 hertz used with load computer 2 hours. By the data 15 days 12 December 2558 to 26 December 2558 during 06.30 PM time 17.30 PM and 18.00 PM time 06. 00.The test data 15 days. Mean solar day throughout the 15 was 352.33 watts per square metre, mean the moisture in the air is equal to 52.94 grams / cubic meter. The average temperature on the panel is equal to 35.74 C mean temperature under the panel was worth 39.75 C mean pressure solar panels was 34.69 volts, current value, the average 1.05 =? The average battery voltage ampere 1 equals 13.76 v. The average battery voltage 2 equals. 13.15 v. mean flow battery 1 equals 0.59 ampere current charging current average battery 2มีค่า was 0.77 ampere current charge pump voltage is equal to the average 13.09. Volt, mean flow pump is to 0.35 ampere, mean voltage inverter was 184.18 v. The average current of inverter of 0.12 ampere. The average load voltage equals the average electricity 12.38 volt lighting lighting equals 0.64 ampere.The cause of performance of solar cell work not full performance since before the cloud came over the sun gives light hits down panel Seoul cell less. The electric power generated 15 days is 36.42 watts as a percentage of 13.00 percent of solar panels by manufacturers specify the temperature under the panels on the solar panels is different. Because the design vent pages.
