1. Background and ObjectiveWith the sustainable development of economy and society, the demand for energy willcontinue to grow. It is a significant task for economic and social development toincrease energy supply, ensure energy security, protect the ecological environment andpromote sustainable economic and social development. The exploitation andutilization of renewable energy is an inevitable choice to ensure the sustainabledevelopment of society. Port Hedland has a tropical desert climate with plenty of sunshine all year round. Theannual average temperature can reach 30 degrees Celsius and the highest temperaturecan reach 46 degrees Celsius. There is a great potential for Port Hedland’s solarresources. The assessment of solar energy resources in Port Hedland provides basicinformation for the development and utilization of solar energy in Port Hedland,which is of great significance to the utilization of clean energy, rational planning ofsolar industry, and the promotion of coordinated development of local economy andecological environment.2. Data sourceThe assessment of solar energy resources is the basis of solar energy development andutilization. Because there are few meteorological observation stations in PortHedland. All data were obtained from the measured total radiation of stationLearmonth and Broome B in each month from 2014 to 2018.The solar radiation data in Port Hedland are calculated according to themeteorological method. This report uses the radiation and observation data from 2014to 2018 to analyze and evaluate the solar energy resources in Port Hedland, so as toprovide scientific basis for rational development and utilization of solar energyresources.3. The assessment of solar resource3.1MethodologyThere are three important indicators for the assessment of solar energy resources ina region, namely GHI, DHI and DNI. The mathematical expressions (Formula2.1.1.) of these three indicators are: GHI=DHI+DNIcos(θ)3.1.1Since it is difficult to obtain GHI data of Port Hedland directly, this study first
