A test array, located at 42.4 degrees latitude, has 16140 -Watt panels for a total capacity of 2.24kW. Monthly output for the array for the year 2019 is given in the table below. The array has a tilt angle of 22.6 (roof pitch 5:12) and is oriented 15 degrees west of due south, i.e., azimuth of 195 according to the system that PV-Watts uses. Answer the following: a) Calculate the observed total annual kWh produced and capacity factor for the year; b) Compute the predicted annual output from PV-Watts for this array with default derating factor of 14.08% given in the web page; c) Calculate the derate factor that when applied in PV-Watts gives the total annual output observed for 2019 (Hint: because the actual output from the array underperforms compared to PV-Watts, the derate factor must be greater than 14.08\%); d) Create a plot of monthly output values in kWh with values from parts a-c; e) short answer: What factors might explain why the actual output is not as good as PV-Watts? Discuss in 1-2 sentences. Open-ended, there is more than one possible correct answer. A test array, located at 42.4 degrees latitude, has 16140 -Watt panels for a total capacity of 2.24kW.
