Summary

An empirical study was performed to obtain a new anisotropic model for estimating of individual hourly sums of solar radiation on vertical south-facing surfaces. The procedure consists of correcting statistically the isotropic model by taking into account the anisotropic character of both sky diffuse and ground reflected solar radiation. Based on the data measured at Budapest-Lörinc station a simple correction function was obtained.

Zusammenfassung

Es wurde eine empirische Studie zur Entwicklung eines neuen anisotropen Modells zur Bestimmung der individuellen Stundensummen der Sonnenstrahlung auf vertikale Südwände durchgeführt. Das Verfahren besteht in einer statistischen Korrektur des isotropen Modells durch Berücksichtigung des anisotropen Charakters der diffusen Himmelsstrahlung und der vom Boden reflektierten Sonnenstrahlung. Mit in Budapest-Lörinc gemessenen Beobachtungsdaten wurde eine einfache Korrektionsfunktion erhalten.
