Develop of Local Flat Plate Solar Heater

A new system of local flat plate solar water heater “LPSH” recommended to be used for heating as step maximizing renewable source energy instead traditional power.The is heat from the atmospheric temperature. Evacuated, double and single glasses were fabricate with same dimensions installed at a latitude angle 31 degree facing towards N-S direction.The experiment has been carried out 24th March 2021 between 8.00 AM 5.00 PM.The collector efficiency depends many parameters such type glass cover, wind velocity overall top loss transfer coefficient.Top coefficient (Ut) plays an important role design collector.Taking this point under consideration present work reduce improve efficiency.The result shows that (LVDG) higher compared (LDG) (LSG).The instantaneous obtain was reduced in (LVDG). The (LVDG), (LSG) achieve around 79, 68 45 %, caused by high increase 12:00 pm.The decreased coefficient. maximum Ut recorded (2.51, 3.77, 6.35 W/ m2 K) pm, respectively.
