OLUWABI ABAYOMI

2. SOURCE OF WEATHER PARAMETER
• PVSYST – Software (meteonorm 6.74)
• Some other data was taken from (Pvgis.com)
Algorithm of the calculation:
• The Olmo model was used for the calculation
Irradiation for different Azimuth and Tilt
angles respectively.
• All other arithmetic was done on Excel
