What causes high potential difference between solar cells and PV modules?
However, several factors can induce high potential difference between solar cells and the PV module frame due to electrochemical interactions (Carolus et al., 2019, Kwembur et al., 2020, Luo et al., 2017, Yamaguchi et al., 2020).
Some of these factors include module encapsulation and design, solar cell's anti-reflection coating, PV system electrical topology and inverter type, environmental/climatic factors (such as humidity, temperature, UV radiation, soiling, etc.), and grounding conditions of the front glass (Carolus et al., 2019, Luo et al., 2017, Naumann et al., 2019).

How much energy does a solar PV system produce in Tehran?
Based on the average data collected, assuming constant power production for one hour, the average energy produced by the PV system in Tehran was 246.1 Wh. Dividing this amount of energy by the installed capacity of the solar panel, the daily PV potential at the study point was calculated to be 4.101 (kWh kWp −1 ).
What is the PV power production potential in Tehran?
The main results of this study revealed that: The PV power production potential in Tehran, characterized by a cold and wet climate, was 4.101 kWh kWp −1 with a capacity factor of 17.09%. In contrast, Ahvas, with its warm and dry climate, had a potential of 3.271 kWh kWp −1 and a capacity factor of 13.63%.
Does weather affect solar energy production in Iran?
The results of this study indicated that the changes in weather patterns in Iran have a direct impact on the estimated solar energy production using Solar Atlas or PVsyst software. This is because weather conditions affect the amount of sunlight that reaches the solar panels and the efficiency of the panels themselves.
Is solar potential overestimated or underestimated in Tehran and Ahvaz?
These values differed significantly from the estimates provided by PVsyst and the Global Solar Atlas. The Global Solar Atlas overestimated the PV potential by 15% and 18.2% in Tehran and Ahvaz, respectively, while PVsyst underestimated it by more than 15% in both locations.
