| Temperature and climatic test chambers for solar technology  Terrestrial thin-film photovoltaic (PV) modules, type suitability and type approval are described in IEC standards; these comprise different processes for testing of the suitability of the design; howvever, they have identical temperature and humidity testing procedures. Climatic Testing for PV modules: 1. Temperature shock cycling test (10.11); 2. Humidity freezing test (10.12); 3. Damp heat test (10.13). Tests for fulfilling of the requirements are: determination of the maximum output; determination of the temperature coefficients; measurement of the nominal operating cell temperature; performance under standard testing conditions; performance at nominal operating cell temperature; hot spot endurance testing. write your comments about the article :: © 2009 Construction News :: home page |
