Answer :
The total number of panels lost 154 panels.
The available panels for a week after the power failure and maintenance is 46,346 panels.
To calculate the number of panels that can be produced in 2 quarters, we need to consider the production capacity per hour, the number of shifts, and the number of working days.
Number of cells produced per hour:
10 solar tabber stringer machines ˣ 100 cells per hour = 1,000 cells per hour
Number of hours worked per day:
24 hours - 75 minutes break = 23.25 hours
Number of cells produced per day per machine:
1,000 cells per hour ˣ 23.25 hours = 23,250 cells per machine per day
Number of cells produced per day by all machines:
10 machines ˣ 23,250 cells per machine per day = 232,500 cells per day
Number of working days in 2 quarters:
5 working days per week ˣ 4 weeks per month ˣ 2 quarters = 40 working days
Total number of panels produced in 2 quarters:
232,500 cells per day ˣ 40 working days = 9,300,000 cells
Since each panel is composed of 200 cells, we divide the total number of cells by 200 to find the number of panels produced:
9,300,000 cells / 200 = 46,500 panels
On day 2, due to a power failure from 3:05 pm to 6:25 pm, production was halted for 3 hours and 20 minutes. Assuming the machines were not able to produce during this time, the loss can be calculated as follows:
Number of cells lost during power failure:
10 machines ˣ 100 cells per hour ˣ 3.33 hours = 3,330 cells
Number of panels lost during power failure:
3,330 cells / 200 = 16.65 panels (rounded to the nearest whole number)
From days 2 to 4, 4 solar tabber stringer machines will be pulled out for maintenance. Assuming the remaining 6 machines are still operational, the loss can be calculated as follows:
Number of cells lost due to maintenance:
4 machines ˣ 100 cells per hour ˣ 23.25 hours per day ˣ 3 days = 27,600 cells
Number of panels lost due to maintenance:
27,600 cells / 200 = 138 panels
Therefore, the total number of panels lost due to the power failure and maintenance is 16 panels (from the power failure) + 138 panels (from the maintenance) = 154 panels.
To find the available panels for a week after the power failure and maintenance, we subtract the lost panels from the total panels produced in 2 quarters:
Available panels = Total panels - Lost panels
Available panels = 46,500 panels - 138 panels = 46,362 panels
Therefore, the available panels for a week after the power failure and maintenance is 46,346 panels.
