Table 1 shows the results for different installation scenarios. It can be seen that for all scenario, the energy production from the PV system is depended on the installation conditions. The scenario 3 shows the higher energy out put but when compared with other scenario it is a very small percentage. Scenario 3 is 0.28% (1,429 kWh/year) and 2.05% (10,349 kWh/year) higher than scenario 2 and 1 respectively.

This value only shows the pre-feasibility technical study of the project. It needs more detailed study such as financial study in further works. Also, for the details of engineering work from the actual site is a very important issue as well.
