Consider a 250 Wp rated crystalline silicon PV module. It results from a manufacturing process that consumes 8kWh/Wp of PV module.

a) What is the total energy consumed (in kWh) during the production of the module?


Assume that the PV module is used in a location where it gives an average annual PV yield of 500kWh over its lifetime of 30 years. Also assume that the Balance of System (BOS) requires a total of 1000kWh for its production.

b) What is the Energy Yield Ratio of the entire PV system over its lifetime of 30 years?


c) What is the Energy payback period for the entire PV system in years?
