Title

A NOVEL TIME‑ EFFECTIVE MODEL FOR DAILY DISTRIBUTED SOLAR RADIATIONESTIMATES ACROSS VARIABLE TERRAIN

Pages

  383-398

Abstract

 Accurate and precisess estimation of spatio-temporal variability of solar radiation is critical. Some commonly used modelsevaluate this variability using methods in which the data required for estimating atmospheric attenuation may not be easilyaccessible for some study areas. Here, a daily solar radiation estimation method which uses ambient AIR TEMPERATURE, aDigital Elevation Model, time of year, and monthly radiation estimates from Solar Analyst model has been proposed. Theobjective was to use AIR TEMPERATURE-based empirical models for atmospheric transmissivity and diffuse fractions to varytotal monthly radiation estimation from Solar Analyst, and then calculate total daily radiation as a fraction of total monthlyradiation by applying a daily transmissivity-based ratio, as AIR TEMPERATURE data are readily available at most locations onthe planet. Results revealed that daily solar radiation can be estimated very well, with Mean Absolute Bias Error of around40– 53 W m− 2 or Mean Bias Error of ± 10%, under all sky conditions at seven sites in diverse climate regions, using significantlyless input data. The presented method is an improvement over previously used methods with Mean Bias Error ofunder 10% but more input parameters. Furthermore, the hourly solar radiation values can be calculated using the presentedmethod using the ratio between daily and hourly radiation, for example from literature values and estimated daily insolation. The result also showed that the method is more useful for those stations with substantially higher numbers of sunny daysthan cloudy or partly cloudy days because the uncertainty of the model decreased from cloudy to sunny sky conditions. Theimplemented Digital Elevation Models environment of this method makes it applicable in many studies that need spatialestimation of solar radiation, especially for solar energy generation projects.
