A solar panel measures 0.53 m by 1.5 m. Indirect sunlight, the panel delivers 7.5 A at 4.2 V. If the intensity of sunlight is 300 W/m2, what is the efficiency, as a percentage, of the solar panel in converting solar energy into electrical energy?
Find the power absorbed by the panel by using the intensity of sunlight and the area of the solar panel. Find the power delivered using the voltage and current. Use the power delivered and power absorbed to find the required efficiency as shown below
