The front cover of solar photovoltaic modules is mostly made of 3.2mm, 2mm or thinner glass. When under wind or other dynamic loading stress, the performance of the PV modules might be affected. This article analyzed data of dynamic load test on several different types of PV modules, and got the conclusion that the dynamic load stress could harm the string ribbon or interior circuits of the PV modules, and would therefore lead to capacity reduction and less insulation.

Different Types

Solar photovoltaic systems have long been used to generate power for various applications since the 1990s. The efficiency of the solar photovoltaic model is determined by the available solar radiation and various environmental factors such as humidity, temperature, dust, snow, bird droppings, etc. This environmental factor reduces the performance of the photovoltaic modules. This document discusses the different technologies for cleaning PV modules with their performance in different environments. The problems associated with the different types of cleaning systems are also discussed.

The following thesis paper investigates the possible methods to perform a dynamic load test on a morphing winglet. A morphing winglet design capable of deflecting in the cant direction was developed by a joint partnership between Ryerson University and Bombardier Aerospace. In order to validate the model and complete a proof of concept, a loading fixture was required to test the structural integrity of the winglet under a defined load. Upon completion of an enumeration study of planar four-bar linkages, a passive R-P-R-P mechanism was designed to apply a constant perpendicular load throughout the cant motion. A design of the half size loading fixture was developed, optimized and manufactured to integrate with an existing cant module. The dynamic loading model was validated by producing a positive correlation between the theoretical analysis and the experimental results, leading to a successful proof of concept for a full scale test.

And Function

Dynamic load test is to measure the natural vibration characteristics of the bridge structure or the forced vibration characteristics under dynamic load, and to evaluate the driving performance, driving safety and comfort of the bridge through dynamic load test. In order to evaluate the stress state and working performance of a reinforced concrete box-ribbed arch bridge, the load test of the bridge is carried out. Dynamic load test is used to test the inherent fundamental frequency, damping ratio and impact coefficient of the bridge through pulsation test and sports car test. Through the experiment with the key parts of the stress (strain) and displacement load and other important data, through analysis and study, the comprehensive analysis of the phenomenon of calculation and test, a comprehensive performance evaluation structure and function whether meet the design requirements, to provide technical basis for the safety of the bridge operation, and provide the original material for the bridge maintenance and management in the future.

This paper made the same size of reinforced grouting material vertical bending cantilever beam and reinforced concrete ones, respectively for the same static and dynamic load test, the static load for drab one-time loading level, dynamic load as low reversed cyclic loading, observe their cracking and deformation condition, draw the response relationship between the load and displacement hysteresis curves, skeleton curves, Test and data results show that the stress and deformation of the reinforced grouting material member is close to or even better a reinforced concrete member, so it is reliable to replace concrete with grouting material.
