The Effect of Cloudy Days on the Annual Typical Meteorological Solar Radiation for Armidale NSW, Australia

摘要

The most common data for describing the local solar climate is through what is called Typical Meteorological Year data (TMY). Typical solar radiation data is very important for the calculations of many solar applications. Previously, the calculation TMY for solar radiation has been already conducted for Armidale NSW, Australia, as typical solar radiation years for Armidale were generated from the daily global solar radiation data measured for 23 years, utilising the Finkelstein-Schafer statistical method. By all means, TMY of solar radiation showed the how solar radiation is potential in Armidale and would be a real help for solar energy generation systems' designers in this region for all building applications varying between residential, educational, administrative and commercial for sizing and maximising efficiency of such systems by using the tabular TMY outcome for the each day of the year. However, in this study, cloudy days are considered, a revised TMY of solar radiation for Armidale is generated. It has been found that, the consideration of cloudy days has significant impacts on the potential of solar radiation in Armidale which is directly related to forming a real picture of this potential. Such impacts are affecting inversely the expected amount of energy generated and/or heat from solar radiation in Armidale.
