The graphs show the performance of a crystalline silicon solar panel. Figure 1 Current (A) 4 12 10 14 10 8 6 4 2 0 0 10 20 1000W/m² 800W/m² 30 600W/m² 40 400W/m² 600 550 500 450 400 350 300 Power (W) 250 200 150 100 50 0 50 Voltage (V)  200W/m² Current (A) 16 14 12 10 8 6 4 2 0 0 10 25°C Figure 2 20 50°C 30 <75°C 40 50 Voltage (V) a. The efficiency of the solar panel is the ratio of maximum power output to solar power input. The efficiency of the solar panel is given as 22.5%. From Figure 1, what is the area of the solar panel? b. The "fill factor" of a solar panel is the ratio of maximum power to the product of the cell short circuit current and open circuit voltage. Fill Factor = Pmax/IscVoc What is the Fill Factor for the solar panel at 1000 W/m²? Is it the same at 200 W/m²? c. Figure 2 shows the effect of temperature on cell efficiency. Cell efficiency decreases with temperature. The data were measured at 1000 W/m². Temperature dependence on cell efficiency can be expressed as nt no = 1y(TTsc) = Where nt efficiency at a temperature T, no = efficiency at a standard temperature Tsc. The y is the constant of proportionality. The standard temperature is 25 deg.C. From Figure 2, what is the value of y? The graphs show the performance of a crystalline silicon solar panel.
