RESEARCHES

Before the construction of full-size prototype constructions, the models in 1:5 scale were made, their effectiveness of insulation from air sounds in acoustic conditions in situ has been tested, among others based on some of the requirements of EN 1793-6: 2018.

Laboratory tests of selected physical parameters of models of such devices were carried out. In addition to the effectiveness of insulation from air sounds, their electrostatic parameters, vibration parameters using LDV laser techniques, as well as resistance to long-term vibrations at the main resonance frequencies, including the ability to maintain initial photovoltaic parameters were also studied.

In order to examine the effect of long-term vibrations on the mechanical parameters and energy efficiency of PV panels, models 1:5 were tested in artificial lighting conditions on the same specially constructed laboratory test stand, on which their vibration parameters were tested. Their more accurate characteristics after completing the entire measurement cycle were obtained in ML System laboratories.

The tests allowed to determine the possibility of introducing both solutions (glass-PV-glass and PC-PV-PC) as useful for further research at the design, construction and testing stages of the future prototype installation, consisting of two full-size HPVNRB panels with a total dimensions of 4000x4000x10 mm, to be tested in true road/rail communication conditions for the prototype site location.

The solution was intended for implementation in hot Cypriot climate, as well as in Polish conditions requiring increased protection against hail (summer) and ice (winter).
