Numerical procedures and their practical application in PV modules analyses. Part I: air mass
2019
Abstract The subject of the article is aspects of PV modules and cells measurement, with the use of natural sunlight. A light source is an important element during calibration and measurements of solar cells and modules. All designers of artificial light sources try to recreate natural light using so called measurement tables. The correctly performed measurement, i.e. meeting all the appropriate atmospheric conditions, guarantees obtaining the result with the use of a reference spectrum. The article has two main aims. The first aim of the article is to answer the question asked earlier - if the sunlight spectrum registered in appropriate conditions is so good that it serves as the reference…
Numerical procedures and their practical application in PV modules’ analyses. Part II: Useful fractions and APE
2019
Abstract The article regards aspects of PV modules tested with the use of natural sunlight. The analysis of spectral structure of solar energy resources in southern Poland, carried out on the basis of meteorological data originating from SolarLab PW Wroclaw and AGH Krakow, Poland [ 1 ] was used in the article. It is a continuation of the article: Analysis of solar energy resources in southern Poland for photovoltaic applications [ 1 ], describing the method to determine spectral parameters of average photon energy (APE) and useful fraction (UF) with the use of a solar radiation spectrum simulator. This article, however, includes an experimental presentation of their impact on PV conversion …
