“…The temperature is a crucial parameter that affects the performance of PV modules. In order to calculate the temperature corrected performance ratio, PR corr , firstly the temperature corrected DC energy output, E corr , must be performed using the temperature effects with the following equation [18,19]:…”

The aim of this paper is to present three years of an evaluation of the performance and degradation rate of three different crystalline silicon-based photovoltaic (PV) modules in the Saharan environment. The PV modules are: mc-Si (multi-crystalline), c_Si (mono-crystalline, back contacted) and HiT (heterojunction with intrinsic thin-layer); they are installed in Saida which is located at the proximity of Algeria's Sahara. Two methods were used to calculate the degradation rate; the effective peak power of the PV modules and the temperature corrected performance ratio. It was found that the HIT technology performs worse than the other technologies with the highest degradation rate, ranging from −1.53%/year to −1.92%/year. The mc_Si PV and c_Si PV module technologies present a lower degradation rate than the HIT technology in the range of −0.74%/year to −0.83%/year and −0.58%/year to −0.79%/year respectively.

“…Although there are various research efforts that focus on the degradation rate of PV systems worldwide [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], there is lack of references describing the behaviour and degradation analysis of existing PV systems in the United Kingdom (temperate maritime climate). Therefore, in this paper, the data of 3000 PV installations across the UK are refined, and the extracted degradation rates are analyzed over a period of ten years (2008 to 2017).…”

“…Similar results were reported by [19] where the degradation rate in southern India was observed at -1.3%/year. Furthermore, in Thailand, the degradation rates were widely different, ranging from -0.5% to -4.9%/year [20]. A study conducted by [21] found that the PV degradation rate based on the long term of outdoor exposure in northern Thailand was equal to -1.5%/year.…”

This article presents the degradation rates over eight years for 3000 PV installations distributed across the UK. The study considers three PV cell technologies, namely, monocrystalline silicon (Mono-Si), polycrystalline silicon (Poly-Si), and thin-film Cadmium Telluride (CdTe). The available raw data undergoes three key stages: normalization, filtering, and aggregation, before the degradation analysis of the considered installations. This algorithm can be considered as one of the paper contributions. Results show that a maximum degradation rate of-1.43%/year is observed for the CdTe type, whereas Poly-Si and Mono-Si PVs have annual degradation rates of-0.94% and-0.81% respectively. Moreover, this article exploits the monthly mean performance ratio (PR) for all the examined PV sites. The highest PR value of 87.97% is calculated for the Mono-Si PV installations, while 85.08% and 83.55% is calculated for Poly-Si and CdTe installations, respectively.

“…The degradation will differ from cell to cell, module to module, etc., hence it is more useful to talk about a population of degrading modules than of the degradation of an entire system. Most causes for performance loss can be associated with the module package but some degradation of the semiconductor device cannot be excluded [3] [4] [5]. Potential induced degradation (PID) can reduce the efficiency of a PV module.…”

The solar photovoltaic (PV) market has grown very rapidly throughout the past 15 years and is quickly becoming an international, non-subsidized market with increased demand for performance certainty. An increasing number of studies analyze long-term monitoring data to determine degradation rates, or "rates of change" (RoCs). Analyses of long-term monitoring data give insight in the performance of PV power plants over time, but are found to be sensitive to uncertainties, especially those related to irradiance measurements using silicon reference cells. The case study analysis shows, however, that the RoCs are much lower if reference cells are adjusted for soiling, drifting and sensor replacements or if satellite irradiance data is used. This indicates that the impact of biased irradiance data should not be underestimated. It was also found, that the distribution of RoCs is strongly influenced by the age and size of the selected systems, underlining the importance of system selection. The case study analysis indicates that crystalline silicon PV systems operating for 8+ years are expected to show a "rate of change" of −0.5% per year or fewer. In this paper the 15-minute data has been collected from a solar photovoltaic generating station installed on the roof of engineering college building and efficiency/degradation of solar panels have been analyzed and reported.
