Calculation of solar PV module efficiency

Given values: irradiance-1000 watt per square meter, solar module rating=345 Watt peak at STC, module length=1998 mm, module width=1010 mm;

Module Efficiency(η)=Module Rated Power/(Irradiance× Module Area)×100
Module Area=Module Length ×Module Width (1998 mmx1010 mm)
Module Rated Power is the power output of the solar module under standard test conditions (STC), which is 345 Watts in this case.
Irradiance is the amount of sunlight falling on the module surface, given as 1000 Watts per square meter.

Answer is 17.1%
