Question

It is required to install solar photovoltaic module to supply electricity for a small house in Taif city, The residence devices in the bourse is shown in the table below. The module characteristics as follows: The system Voltage is 24 V DC and the buttery type and characteristic is as follows: 12 Volt 200 Ah Heavy Duty "Extreme" by VMAXTANKS Dimension: 20.8 L times 8.7'W times 9.0 H (9.8 h to top of terminals) Terminals Posts: SAE + 3.8" STUD (Posts included) MODOO: D.7 Bulk charging voltage required 14.4-14.9V; Float voltage: 13.5V If you know that the minimum peak sun time is 4 bout and autonomy day is 2: Calculate. How many module required, and its combination and parallel ? How many batteries required and what is he combination series and parallel ?

Explanation / Answer

a) Total appliance use =179.029 Wh/day

Total panel energy needed = 179.029*1.3 = 232.7377

Number of panels needed = 232.7377/3.43 = 67.85 mudules

The actual system should be powered by at least 68 panels in series combination.

b) Nominal voltage = 12V

Total appliance use = 179.029 Wh/day

Days of autonom = 2

Battery capacity = (179.029*12)/(0.85*0.6*12) = 58.05 Ah

Number of batteries = 58.05/20 =2.95

Three batteries in series combination are required.
