Step 1: Calculate Total Array Capacity First, determine the total daily energy that the solar array must generate, accounting for system losses. E_generated = Daily Energy RequirementSystem Efficiency = 4.8 kWh/day0.8 = 6 kWh/day = 6000 Wh/day Next, calculate the total Watt-peak (Wp) required for the solar array using the average peak sun hours (PSH). P_array = E_generatedPSH = 6000 Wh/day5 hours/day = 1200 Wp The total array capacity required is 1200 Wp. Step 2: Calculate Module Configuration Given: Total Array Capacity (P_array): 1200 Wp Solar Panel Max Power (P_max): 300 Wp System Voltage (V_sys): 24 V DC Solar Panel Voltage at Max Power (V_mp): 32 V Calculate the total number of panels (N_total). N_total = P_arrayP_max, panel = 1200 Wp300 Wp/panel = 4 panels Determine the number of panels in series (N_s). For a 24V system, a single panel with V_mp = 32 V is suitable for charging via an MPPT charge controller. N_s = 1 panel/string Determine the number of parallel strings (N_p). N_p = N_totalN_s = 4 panels1 panel/string = 4 strings The module configuration is 4 total panels, with 1 panel in series per string and 4 strings in parallel. Step 3: Calculate Battery Bank Sizing Given: Daily Energy Requirement (E_L): 4.8 kWh/day System Voltage (V_sys): 24 V DC Autonomy: 2 days Depth of Discharge (DOD): 50\% = 0.5 First, calculate the daily energy requirement in Amp-hours (Ah). E_L, Ah = E_L × 1000 Wh/kWhV_sys = 4.8 kWh/day × 1000 Wh/kWh24 V = 200 Ah/day Now, calculate the required battery bank capacity, considering autonomy and DOD. Battery Capacity (Ah) = E_L, Ah × AutonomyDOD = 200 Ah/day × 2 days0.5 = 800 Ah The required battery bank capacity is 800 Ah. Step 4: Determine Charge Controller Minimum Current Rating Given: Number of parallel strings (N_p): 4 Solar Panel Current at Max Power (I_mp): 9.38 A Safety Factor: 1.25 (standard practice for continuous current) Calculate the maximum current from the solar array. I_array, max = N_p × I_mp = 4 strings × 9.38 A/string = 37.52 A Determine the minimum current rating for the Charge Controller, applying a safety factor. Charge Controller Rating = I_array, max × Safety Factor = 37.52 A × 1.25 = 46.9 A The minimum current rating required for the Charge Controller is 46.9 A.
