Proposed Models to Improve Predicting the Operating Temperature of Different Photovoltaic Module Technologies under Various Climatic Conditions

Abstract

The operating temperature is an essential parameter determining the performance of a photovoltaic (PV) module. Moreover, the estimation of the temperature in the absence of measurements is very complex, especially for outdoor conditions. Fortunately, several models with and without wind speed have been proposed to predict the outdoor operating temperature of a PV module. However, a problem for these models is that their accuracy decreases when the sampling interval is smaller due to the thermal inertia of the PV modules. In this paper, two models, one with wind speed and the other without wind speed, are proposed to improve the precision of estimating the operating temperature of outdoor PV modules. The innovative aspect of this study is two novel thermal models that consider the variation of solar irradiation over time and the thermal inertia of the PV module. The calculation is applied to different types of PV modules, including crystalline silicon, thin film as well as tandem technology at different locations. The models are compared to models that are described in the literature. The results obtained in different time steps show that our proposed models achieve better performance and can be applied to different PV technologies.

Enhancement of PV Panel Power Production by Passive Cooling Using Heat Sinks with Perforated Fins

“…According to the PV panel data sheet [43], in this scenario, the t NOCT should be 45 ± 2 • C, while the operating temperature from simulation was 47.16 • C. Taking into account the good matching between results and expectation, further validation was conducted. Therefore, by comparing the results from modelling with those obtained by using the acknowledged Equation (1) [14,47], the following variation of the operating temperature was obtained (Figure 6).…”

Modelling, simulation, and measurement of solar power generation: New developments in design and operational models

“…The re-engineering of empirical solar power generation models is advocated by the introduction of explicit power generation models; by introducing double linear correlation (Schwingshackl et al [ 16 ], Mattei et al [ 17 ], Olukan & Emziane [ 18 ], Nguyen et al [ 19 ], Barykina & Hammer [ 20 ], Brito et al [ 21 ], Sarniak [ 4 ], Ayaz et al [ 22 ], Agyekum et al [ 23 ], Akhsassi et al [ 24 ], Kaldellis et al [ 25 ], Abe et al [ 26 ], Zouine et al [ 27 ], Muneeshwaran et al [ 28 ], Kalogirou [ 29 ], Cotfas et al [ 30 ]); in retrospect, Schwingshackl et al [ 16 ] demonstrated that incorporating wind data into the SPGMBCT models improves the prediction of cell temperature compared to standard methods. In the same manner, Mattei et al [ 17 ], observed that the cell temperature model based on the thermal properties in lieu of wind speed or irradiance is weak in predicting cell temperature.…”

“…Pertinently, Olukan & Emziane [ 18 ] modified the SPGMBCT model without the wind speed; however, they recorded a good prediction of cell temperature. Outstandingly, Nguyen et al [ 19 ] modified the SPGMBCT model with wind speed, thermal inertia (thermal diffusivity) and irradiance to obtain a better prediction of cell temperature. In the same vein, Barykina & Hammer [ 20 ] applied the Faiman model/parameters to achieve a better prediction of cell temperature relative to the standard model.…”

Numerical Modeling in Energy and Environment

“…Several works were aimed at renewable energies, such as Damota et al [1,2], who analyzed a vertical axis wind turbine Savonius type with CFD (computational fluid dynamics). Nguyen et al [3] developed two models to improve the precision of estimating the operating temperature of outdoor photovoltaic modules. Shen et al [4] conducted experimental tests and numerical calculations to analyze the hydraulic vibration and possible exciting sources of analysis in a hydropower system.…”
