In this paper, some results of accelerated ageing tests on 15x15 cm2 mini-solar modules are presented. Two identical sets of mini-modules were created for two types of accelerated test – continual thermal stress at the 80 °C temperature in dark chamber and continual humidity test at the temperature of 37 °C and relative humidity (RH) over 95 %. Standard lamination process for normal EVA was used for EVA and TPU samples to prepare ordinary PV structure with white TEDLAR at the backside. For double-glass samples with PVB incorporated, an autoclave treatment was additionally applied. Commercial mono-Si solar cell (5x5 cm2) was inserted into each mini-module to evaluate and compare the main solar cell parameters before, during and after the degradation procedure. No significant degradation was observed for EVA mini-modules, while the changes in samples with TPU encapsulant are unacceptable.
