| Summary: | This paper presents two methods to estimate hourly
solar radiation from available weather data. The two methods
presented in this paper are based on atmospheric
transmittance determination using available meteorological
data. In the first method a decision matrix was used while in the second method regression correlation of meteorological parameter was used. The calculations results were evaluated using statistical parameter. Though the result shows both of the methods perform well, more satisfactory results were obtained from first method with Root Mean Square Error of 87.6 Watt/m2, Normalized Root Mean Square Error of 8.29%, correlation coefficient of 0.95 and index of agreement of 0.97.
Furthermore, the first method only need RH and ambient
temperature data which commonly measured in every
meteorological station. |
