4. Fire Station #4 in Corvallis has a solar cell array on its roof. a. The solar cells mounted on the top of the station are made by the company Trina Solar and are model TSM-235 PC. At the end of this document is the two-page data sheet for these solar cells.Data sheets are technical documents that contain important specifications about the solar cells. Look at the data sheet and find this information about the solar cell : [ 10 pts] Maximum voltage output at standard test conditions (STC) Maximum current output at STC Module Efficiency at STC Height of a solar cell module (give your answer in meters) Width of a solar cell module (give your answer in meters) b. Details about the solar cell array for Fire Station #4 is available here. How many solar cell modules are on the roof of the fire station? (be careful, there are fewer than 100) [ 2 pts ] c. Assuming that the light intensity hitting the solar cell array is 1.000kW/m², calculate the total power hitting the solar cells. [ 4 pts] d. Shown below is a graph of the electrical power generated by station on Saturday, October 30,2021, a generally sunny day in Corvallis. From the graph, estimate the average power generated in the afternoon, when the sun was the brightest. [ 2 pts]

e. Calculate the actual efficiency of the solar cell array on October 30th. f. Compare the actual efficiency you calculated to the value reported in the data sheet. If they don'tmatch, suggest some things (besides cloud cover) that you think might impact the efficiency ofconverting solar power to electricity. [3 pts]
