The PV system performance will be simulated by PVsyst software. PVsyst is a software package to study, size and analyze different types of PV systems. For this research PVsyst will be used to simulate energy yield of a PV system with regards to local meteorological data. Energy yield will further on be used to calculate the cost saving benefits in the financial analysis, which will be essential in determining the feasibility of each site. Roof area in the campus varies from building to building therefore the simulation will be based on a defined system output. The main output needed for the financial analysis will be energy yield.
