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?

Thirteen posts in a row? And no indication of what you have done so far? You must be taking a test! All other posts have been removed ... to give you time to think about YOUR responsibility to let tutors know how you have tried to answer each set of questions. Remember this ~~

If all you do is post your entire assignment, **with no evidence of thinking on your part**, nothing will happen since no one here will do your work for you.

But if you are specific about what you don't understand about the assignment or exactly what help you need, someone might be able to assist you. **Ask specific questions! **
