Design of a Stand-Alone (Off-Grid) Solar PV System A small health center requires a reliable power supply. Your task is to design a complete Stand-Alone Solar PV System to meet the load requirements based on the technical data provided below. Given Data: Daily Energy Requirement (EL): 4.8 kWh/day System Voltage (EL): 24 V DC Average Peak Sun Hours (PSH): 5 hours/day Solar Panel Specifications: Max Power (Pmax): = 300Wp Voltage at Max Power (Vmp): = 32V Current at Max Power (Imp): = 9.38 A System Losses: Assume a total system loss factor of 20% (0.8 efficiency). Autonomy: The system must provide power for 2 days without sun. Required Calculations: Total Array Capacity: Determine the total Watt-peak (Wp) required for the solar array. Module Configuration: Calculate the total number of panels (Ntotal). Determine how many must be in series (Ns), and how many in parallel (Np), to match the 24V system (considering Charge Controller requirements). Battery Bank Sizing: Calculate the required Amp-hour (Ah) capacity of the battery bank assuming a 50% Depth of Discharge (DOD). 1 Charge Controller: Determine the minimum current rating (Amps) required for the Charge Controller. Required Deliverables (Design & Mapping): Your final report must include the following visual elements, similar to the DC Winding layout: A. Solar Array Layout Diagram: A "Developed Diagram" showing the physical arrangement of the panels (Series strings and Parallel connections). B. Single Line Diagram (SLD): A schematic showing the flow of power

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 = 1
