Solar Radiation and Uncertainty Information of Meteonorm 7
Abstract
The solar radiation database meteonorm is widely used for solar thermal, PV and building simulation in form of stand alone software or included in the most common simulation software (like PVSyst or Polysun). Version 7 appears in November 2011 (www.meteonorm.com). This article shows the news concerning the solar radiation database as well as the uncertainty and trend information. Uncertainty of the yearly values of global and direct radiation as well as beam radiation will be given. Uncertainty is an important information for planners. Up to now this information hasn’t been included in common solar radiation databases. The variation of uncertainty throughout the world is quite big.
