*3.3.3 Load calculations*

The Power = voltage\*current P = 6\*3.3 = 20 W Total power (Energy consumption) = the power\*number of devices Total power = 20 W \*1 = 20 W Power (watts/hour) = total power\*required time loads P (W/h) = 20\*6 = 120 W/h The required power of cells = energy consumption/system factor The required power of cells = 120 W/0.81 = 148 Wh Battery capacity = the required power/system voltage Battery capacity = 148/12 = 12.31AH The cell Production = 18 The No. of Modules = battery capacity/cell production The No. of Modules = 12.31/18 = 0.68 ≈ 1modules
