Question

Suppose you are designing a roof top grid connected PV system for home in Kansas City, MO.Peak sun hour (PSH) for Kansas City in summer, winter and yearly average are 5.5, 3.5 and 4.35hours respectively. Record low and high temperature is -28°C and 44°C respectively.Approximate geographical position: Latitude 39°N and Longitude 95 W. The roof of the house is not an ideal one. It faces 600 towards the south from the east. The roof has rise:run ratio of 3:4. Energy consumption information of the house: Yearly 3600 kWh. Maximum energy consumption was found to be in February, which is 350 kWh and minimum is 225 kWh, found tobe in June. Which PSH you'll choose to design this system and why? What would be the module's azimuth angle What would be the module angle? What is the average monthly load? What is the average monthly load? e. If you are supposed to design the system based on monthly load, which load size youе.should prefer to be in the safer side? (Points 2) f.Based on the answer of previous question (6.e), what will be the daily average load? g.Considering no losses what would be the DC system size (i.e. array size), and what would be its unit? (Points 3) h.Based on the losses listed in the table, what would be actual DC system size? (Points 3) i.You are considering DC to AC ratio 1.1 for the system design. Selected inverter has efficiency 97%. Based on this information calculate the ac rating of the inverter and hence the rated DC input power. (Points 2+23D4) j. Use PVWatts, input necessary information based on this problem, write down the annual energy production, highest and lowest monthly energy production.
