1. A home in Chicago receives 5.5 hours of sunshine per day throughout the year. The household has a daily electricity usage of 18 kWh. An array of photovoltaic modules is required to provide this load. The array comprises 395-W modules. The array of modules must adhere to the following specifications: Vmp = 55V, I = 6A, V = 65V,1 = 6.5A; the recommended voltage for the maximum power point tracker (MPPT max) is 1,000 V, and the recommended current for the power conditioning unit (IPCU,max) is 36 A. A battery operates at 100 V and 25 Ah. The battery stack must provide three days of power delivery (in the event of the sun not shining), and the batteries may not discharge by more than 70%. The power conditioning unit has an efficiency of 97%. (a) Calculate the number of photovoltaic modules required, and specify how they should be connected. (b) Specify the energy requirement (kWh) and number of batteries. (20 points) 1. A home in Chicago receives 5.5 hours of sunshine per day throughout the year.
