The energy consumption rate of the average american is 1402 watts during the day and 1052 watts per night. a small town with a population of 452 people wants to meet its energy demand using only renewable energy systems. they plan to use a combination of solar and pumped storage hydroelectric technologies. the solar electric panels will provide the energy required during the day as well as pump water from a lake to a reservoir for hydroelectric power generation. the hydroelectric power will be used for nighttime power requirements. the top of an ideal location for the water reservoir is 78 m above the proposed hydroelectric pump/generator system. the hydroelectric pump/generator system has a 55% pump efficiency and a 65% generator efficiency. individual solar panels have an area of 2.8 m2with an efficiency of 35%. the average irradiance for the town is 800 w/m2assume that the day starts at 7am and night starts at 6 pmdesign the power generation system for the town by estimating: i. minimum depth of the reservoir required if the average area across the reservoir is 2105 m2,ii. the minimum size of the penstock pipe requirediii. the number of solar panels required in the arraynote: 1.state your assumptions clearly2.be sure to account for potential head losses due to friction. 3.neglect minor losses
