摘要: The impact of photovoltaic (PV) hot-spots is assessed through the analysis 2580 polycrystalline silicon PV modules distributed across U.K. were categorized into eight different groups using percentage power loss. All modeled cumulative density function, state-of-the-art geographical mapping, and performance ratio (PR) analysis. Significantly, it was found that 92.15% affected by hot-spotted string are located in northern U.K., where effect low-temperature levels, heavy snow, hoarfrost more significant. Finally, distribution only one solar cell likely (82.41%) coastal locations. Hence, locations expect to have lower risks for causing multiple cells modules, compared central colder PR all examined analyzed. It evident mean significantly reduced due existence modules. least difference between healthy equal −0.83%, whereas most calculated at −15.47%.
