Solar power generation and warming temperatures

What is the relationship between air temperature and photovoltaic power generation?

The temperature of lake is higher (1.6 °C) than land, and the photovoltaic power generation is the same as the characteristic of the temperature (798 kW h). There is a non-linear relationship between air temperature, solar radiation and photovoltaic power generation.

Do solar power plants increase local temperatures?

Sun et al. (2022) addressed the photovoltaic heat island effect, revealing that larger solar power plants increase local temperatures, challenging theoretical models and raising concerns for large-scale installations (Sun et al., 2022).

Do photovoltaic power plants affect air temperature?

The effect of photovoltaic power plants on air temperature in the land is also studied. However, the impact of the temperature difference between land and lake on the power generation is less based on field surveys, and the impact in this part needs to be further researched.

Does climate affect solar cell performance?

Exploring case studies from diverse geographic regions reveals the varied impacts of climate on solar cell performance. In the scorching heat of Nevada, USA, where temperatures often exceed 100°F (37.8°C), solar cell efficiency faces challenges.

How does temperature affect solar power output?

Vmpp, representing the voltage at which the solar cell achieves its peak power output, undergoes a decrease due to a shift in the voltage-temperature coefficient caused by temperature increases (An et al., 2019). In terms of current output, solar cells exhibit variations with changes in temperature.

What is the relationship between air temperature and solar radiation?

There is a non-linear relationship between air temperature, solar radiation and photovoltaic power generation. Power generation presents a stair-like distribution with the increase of solar radiation. The air temperature 15 °C is a critical point.
