Method for Determination of Operating Temperature of Building Photovoltaic Module

There is no national standard and international standard about nominal module operating temperature (NMOT) test methods for Building Integrated Photovoltaic (BIPV) modules. An in-lab testing method for measuring NMOT of BIPV modules is proposed. Based on the real operation condition of solar cell, the effect of ambient temperature, wind speed and optimal load resistor to operating temperature were analyzed. The surface temperature, interior temperature and back temperature of BIPV module were measured and the NMOT was determined.

The increase of operating temperature on a photovoltaic (PV) cell degrades its electrical efficiency. This paper is organized to describe our latest design of an aluminum substrate—based photovoltaic/thermal (PV/T) system. The electrical efficiency of the proposed PV/T can be increased by ∼ 20% in comparison with a conventional glass substrate-based PV. The work will benefit hybrid utilization of solar energy in development of building integrated photovoltaic systems.

Accuracy And Precision

Solar glass of low iron content plays an important role to increase the optical absorption of solar cells. The national standard stipulates the iron content in the glass without specified testing method. In this paper, we conducted three parallel analytical methods (1,10-Phenanthroline spectrophotometry, FAAS and ICP-OES) to determine the iron content in the same glass and evaluated the results in terms of detection limit, accuracy and precision. Although all three methods can detect the existence of iron, the analytical results are different to some extent. At last we propose a preferred method for commercial solar glass monitoring.

In regard to its hygroscopic properties, particleboard is dimensionally unstable material when exposed to water or in the atmosphere of high level of humidity. Since today several different standardized methods for determination of thickness swelling exist, the aim of this study was focused on comparison of different testing methods. In this aim, three different methods for determination of water soaking and thickness swelling were compared, two of which were defined by national standard SRPS D.C8.104 and one was defined by European standard EN 317. The results of testing of both properties have shown no significant difference between the EN method based on 50?50 mm test pieces and the SRPS method based on test pieces of 100?100 mm format, suggesting that these two methods can be used alternatively. On the other hand, the results obtained by the SRPS method utilizing the 25?25 mm test pieces, differed significantly from both previous methods. The results were lower for both water soaking and thickness swelling regardless of panel thickness.
