TesTs of hail simulaTion and research of The resulTing impacT on The sTrucTural reliabiliTy of solar cells badania symulacyjne wpływu opadów gradu na niezawodność konsTrukcji ogniw słonecznychThe mandatory tests of resistance to hail is carried out in order to qualify solar cell modules according to standards (IEC 61215 and IEC 61646). The efficiency of modern photovoltaic systems decreases significantly, when the crystalline structure of solar cells is damaged as a result of climatic factors, such as wind, hail, etc., which are similar to mechanical-dynamic effects. This work presents a conducted research of efficiency and reliability of solar cells, simulating hail effects. A testbed was created specifically for carrying out experimental research. During the research, solar elements were exposed to impact, cyclic dynamic loads, with the frequency of revolutions of the balls simulating hail ranging from 5 to 20 Hz, the amplitude of the impact excitation acceleration of the solar cell -up to 986 m / s2 and the force amplitude -up to 1129 N. Experimental research results revealed the reliability of photovoltaic modules of different sizes during the simulation of hail. The proposed assessment methodology of hail effects can be successfully applied in studies of the influence of mechanical-dynamic effects of solar cells of different structures.

In comparison to the traditional solutions, active bearings offer great operating flexibility, ensure better operating conditions over a wider range of rotational speeds and are safe to use. In order to ensure optimum bearing performance a bearing control system is used that adapts different geometries during device operation. The selection of optimal controller parameters requires the use of modern optimization methods that make it possible to quickly achieve the assumed parameters. This article presents the method that has been employed to select the parameters of a proportional integral derivative (PID) controller, in which both stochastic algorithms and hybrid methods have been compared. The results show that all of the used algorithms were able to reach the global optimum but only the hybrid algorithm was repeatable in all runs within a low value of the standard deviation. The best solution will be proposed in the future to control an active foil bearing. Analysing of this paper would help to prevent failures of active foil bearing used in the designed rotating machine.
