You are evaluating a solar system in a commercial building. the photovoltaic system has an area of 50 m2 and an efficiency of 22%. the insolation for a given day is shown on the plot below (note that each bar represents one hour of the day) i. what is the amount of electricity generated by the solar system for the day [kwh]? 3 pts ii. if the electricity use peak occurs from 16: 00-18: 00, how much does the system reduce the peak demand [kw]? ii. for peak shaving purposes, you wanted to store 10 kwh of energy using a flywheel. the s2p flywheel has a mass of 200 kg, a radius of 1 m, and ring shape factor (k- 1). with what frequency does the flywheel need to turn 800 700 2 pts 600 500 400 300 드 200 100 0 1 2 3 4 5 6 7 89 101112 1314151617181920212223 hour of day
