Summary Long‐term energy production of photovoltaic (PV) systems is predicted and evaluated using a degradation rate analysis. It is one of the most important factors to consider before investing in PV power plants since it indicates the system's dependability and, hence, profitability. This paper examines the degradation rates of three different PV module technologies in a mountain/cold region, over a 5‐year period; including monocrystalline silicon (mono‐Si), polycrystalline silicon (poly‐Si), and amorphous silicon (a‐Si). This study has been performed using different statistical techniques such as classical and seasonal decomposition (CSD), seasonal and trend decomposition using loess (STL), Holt winters (HW), and linear regression (LR). According to the obtained results, a‐Si modules have the highest degradation rate with values varying between 1.12 and 1.17%/year, followed by mono‐Si (0.69–0.98%/year) and poly‐Si (0.11–0.75%/year) technology respectively. This research included an economic analysis to determine the Levelized Cost of Electricity (LCOE) of the three investigated systems. The findings show that crystalline technologies (poly‐Si and mono‐Si) are more cost‐effective than a‐Si, with an LCOE of 0.099 USD/kWh, 0.108 USD/kWh, and 0.138 USD/KWh respectively.

“…How the generated electric current of a PV cell is directly dependent on the solar irradiation (Kumar et al, 2020), the maximum power generation is achieved when the PV cell is placed orthogonally to the Sun, ensuring the maximum incidence of direct sunlight over the cell's surface. Most PV systems, however, are installed using static mounting on the ground or rooftops (Chandel & Chandel, 2021), decreasing the energy harvesting in reason of the constantly changing angle between the PV module and the Sun. A simplified ratio of the electricity not harvested by a PV module concerning its angular deviation from the Sun can be expressed by…”

The photovoltaic module position related to the Sun greatly affects its power production due to the latter being dependent on the irradiation incidence. One-axis trackers are used to physically move the modules so they follow the Sun's daily trajectory and hence increase energy harvesting. This paper investigates how relevant the actuating angular step of a one-axis tracker is concerning the daily and annual energy photovoltaic energy production. An east-west rotational axis with a fixed tilt angle is experimentally analyzed with four different steps: 2°, 5°, 10°, and 30°angular movements. Results are obtained over 1 year and compared to the energy production of a fixed mount photovoltaic module. Only a maximum difference of 1.68% is observed between the tracking strategies. The sky's condition is also considered, where clear or mostly clear days (60.9% of the analyzed period) contributed to 78.8% of energy production.

Herein, the feasibility of a grid‐connected photovoltaic (PV) power generation system with five tracking models in Hefei is evaluated comprehensively. The comprehensive evaluation of grid‐connected PV power generation system mainly includes three aspects: technology, economy, and environment. The results show that the performance ratio of grid‐connected PV system with dual‐axis tracking device is the highest among the five kinds of PV systems with a value of 81.2%, while the performance ratio of grid‐connected PV system without tracking device is the lowest with a value of 77.3%. The grid‐connected PV system with dual‐axis tracking device is economically attractive, so users can be encouraged to purchase and install such systems to meet their electrical energy needs in Hefei. Furthermore, the grid‐connected PV system with dual‐axis tracking device is the most environmentally friendly and contributes to carbon emission reduction. Finally, it is concluded that the adoption of dual‐axis tracking grid‐connected PV power generation system in Hefei area is very attractive, and can provide a certain reference for the local promotion and use of such grid‐connected PV power generation system.
