What is the efficiency of a PV module that produces 200W and is 1m x 1.5m in size? Provide only the number and round to two decimal places if necessary.

a) 10.00%
b) 13.33%
c) 15.00%
d) 16.67%

Answer :

The correct answer is b). 13.33%. The efficiency of a PV module with an area of 1m x 1.5m that produces 200W is 13.33%.

The efficiency of a PV module that produces 200W of power and has an area of 1m x 1.5m can be calculated by dividing the power output by the product of the area of the module and the average insolation (solar irradiance) received on Earth which is 1000 W/m2.

To calculate efficiency (in percentage), use the formula:

Efficiency (%) = (Power Output (W) / (Area (m2) x Insolation (W/m2))) x 100

Efficiency (%) = (200 W / (1 m x 1.5 m) x 1000 W/m2) x 100

Efficiency (%) = (200 W / 1500 W) x 100

Efficiency (%) = 0.1333 x 100

Efficiency (%) = 13.33%

Therefore the correct answer is b). 13.33%.
