This exercise involves the design of a grid-connected PV system with net metering for a residential building. The objective is to calculate the necessary components, including the PV array, inverter, and other equipment, to meet the building's daily energy consumption of 30 kWh. The system will utilize 350 W solar panels, with an assumption of 5 peak sun hours per day. Additionally, the exercise includes an evaluation of the system's cost, projected savings, payback period, and return on investment (ROI), incorporating the impact of net metering on energy consumption.
