During the past few decades, there has been a continual rise in interest in passive and active solar energy uses, not only in the governmental and commercial sectors, but also within the private sector. There is thus a need for taking measurements of solar irradiation and creating local and regional databases of irradiation and synoptic (meteorological) information. However, there is no guarantee...
Diffuse irradiance is a fundamental factor for all solar resource considerations. Diffuse irradiance is accurately determined by calculation from global and beam normal (direct) measurements. However, beam solar measurements and related support can be very expensive, and therefore, shadow bands are often used, along with pyranometers, to block the solar disk. The errors that result from the use of...
