Total Load demand for the entire house can be calculated per night based on the data given in the question. From the questiion we have following data :
Total power consumption of bulbs=4*20=80Watts and they operate for 5 hours hence total energy per night consumed by light bulbs is 80*5=400Whr
Total energy consumption for a TV of 50W for 3 hours=1*50*3=150Wh
Therfore total energy consumption per day/night=550Wh.
Now since the site has peak sun hour of 5 in the lowest month which means that there are 5 hours per day which receives total radiatons of 1000 watts/hr.
Now to calculate the no of solar panel considering the 5 PSH and 550Wh as total power consumptions
Total Output from Solar panel required= 550/PSH= 550/5= 110Watts.
Hence choosing 3 no of solar panels with 50W connected in series to give an output of 150W which will adequate for supplying the entire load. 50W as mentioned on the solar panel is rated output which can not be achieved under any operating conditions.
Hence the rating of individual solar panel shall be 50W and qty 3 and connected to give an output of 150W.
Household with 3 people has following load. Four 20-watt lights for 5 hours per night and...
