(25 points) Recall Assignment 3 where you sized a PV array for a residence in Cincinnati, OH with monthly electric loads (in kWh) as follows in order from January to December: 750, 650, 600, 600, 700, 1000, 1250, 1400, 1200, 900, 600, 700. In that assignment, you sized the array using the peak sun hours under the assumption that all of the solar energy collected would be net-metered to the grid. Now, let's say that the utility company is no longer accepting solar energy produced from a residence, so you need to re-size the array with a battery such that there is no solar over-generation. Design Description and Methodology:Use the Excel Template for hourly solar calculations found on Isidore. Use the LG PV modules and inverter you used in Assignment #3.Develop the spreadsheet model for an average day of the critical month only. This would be a month where solar PV generation is high relative to the electric load (once your model is built, you can easily check a few months if youre not sure of the critical month).Determine the number of modules that maximizes solar use with NO over-generation (i.e., no solar energy should be wasted).Size your PV array using the module specification sheet and Solar Edge inverter that accompanied Assignment #3. Again, assume 12% efficiency losses due to partial shading, wire losses, dirt/dust, and other miscellaneous factors.For your battery bank, assume only one Tesla Power Wall is feasible. See the notes in the Lecture Materials section on Isidore for a discussion on batteries, a suggested algorithm for modeling your battery bank, and the Power Wall specifications. To keep it simple, you may assume no losses in charging/discharging the battery.Compare your answer to your previous design where you used peak sun hours assuming a fully net-metered system.Economic Analysis: What is the cost of your solar PV system? How much electric energy will it save? What is the simple payback of your system? (Assume the installed cost of one Tesla Powerwall is $10,500).What to Submit: A pdf file summarizing your work that includes screen captures of your Excel sheets. Graphs are important in conveying a lot of information, so paste the default graphs from the Excel template. Describe your array size and how it differs from your answer in Assignment #3 for this same residence. Show your work and assumptions for your economic analysis. Submit your Excel file as a backup to document your work.
