Direct normal radiation
WebAs part of the research for techniques to control the final energy reaching the receivers of central solar power plants, this work combines two contrasting methods in a novel way as a first step towards integrating such systems in solar plants. To determine the effective power reaching the receiver, the direct normal irradiance was predicted at ground level using a … http://solardat.uoregon.edu/NorthwestSolarResourceMaps.html
