“…If PV panels can keep producing electricity at an efficacy of 80% or higher for their entire expected lifespan, then they can be considered to have served their purpose. In the past decade, advancements in technology and durability have led to a five-year rise in the assured useable life span of PV modules, from 25 to 30 years [ 53 ]. To accurately predict PV degradation over time, a physics-based degradation model is applied.…”

“…A large-scale photovoltaic plant has been built all over the world, and the long-term stability of their power generation capacity is becoming more important [3]. Predicting the exact level of electricity production during the lifetime of PV modules is the key factor in the PV industry [4,5]. However, the information provided by the manufacturers only allows an approximate sizing of the PV system.…”

This study presents the measured data of the "Oued Keberit" PV plant over a period of four months (January to April 2022) after nearly 6 years of outdoor exposure to the climate of Souk Ahras, eastern Algeria, in order to evaluate the performance of the solar PV system. This evaluation includes the calculation of PV system performance variables such as module performance, final performance and performance of the module references, system losses, photovoltaic friendly efficiency, system efficiency, performance ratio and capacity factor based on measured data, allowing comparison of actual PV system performance and reference values determined by manifacturers. The results showed that the four-month average values of the parameters Eac, Yr, Yf, PR, h, CF are 1.06375125MWh, 4.08h, 4.25h, 1.06, 16.40%, 60.28% respectively. Also, the high efficiency of the photovoltaic system was obtained during winter, due to the low temperature and the sufficient amount of solar radiation. However, the photovoltaic system generates a lot of energy during summer, although there is less output than during the winter season. This is because summer has maximum values for sunshine duration and solar radiation.

This paper presents an outdoor performance monitoring method for degradation studies of perovskite modules, focusing on a large‐area perovskite module (81.9 cm2) over a long‐term monitoring campaign. The module underwent an industrial lamination process to prevent long‐term degradation from environmental factors. The characterization procedure involved degradation correction and determining the temperature coefficients and electrical parameters of the module using initial days of measurements. The results demonstrated temperature coefficients for Isc, Voc, and Pm (α′, β′, and γ) of −0.071%·K−1, −0.119%·K−1, and −0.113%·K−1, respectively, indicating a minimal temperature influence on this technology compared with conventional ones. Using this coefficient, the STC electrical parameters were retrieved from 1‐min power output data, resolving the uncertainty of the indoor/outdoor IV curve measurements caused by the curve scan direction (JV hysteresis effect). We also highlight the initial remarkable capacity recovery effect of almost 16% during the first 2 days of operation. Additionally, a procedure that includes the IV curves analysis taken every 10 min and their translation to standard conditions has been implemented to evaluate the degradation of the module over the long‐term outdoor campaign. The results show three different trends over the period.
