A study, Solar Panels Warm Up and Cool Down Cities, published recently in the journal Nature Cities, found that complete coverage in a city with rooftop photovoltaic solar panels could increase daytime temperature up to 1.5 degrees Celsius during peak summer and can decrease temperature at night up to 0.6 degrees Celsius.
When sunlight strikes a solar panel, it generates direct current (DC) electricity through the photovoltaic (PV) effect. However, solar cells are sensitive to temperature changes, and this sensitivity is primarily attributed to two key factors: the temperature coefficient of voltage and the temperature coefficient of power.
It’s complicated: Rooftop solar cells can affect the temperature of a building in several different ways. (Courtesy: iStock/MarioGuti) A systematic review of 116 papers looking at how solar panels affect the surrounding environment has found that they can significantly warm cities during the day.
Prolonged exposure to high temperatures can lead to the degradation of materials used in solar panels. Over time, excessive heat can cause the soldering connections between cells to deteriorate, leading to reduced panel performance and potential failure.
Pavao-Zuckerman, lead author Greg Barron-Gafford of the University of Arizona School of Geography and Development, and their research colleagues recently published their findings in the journal Nature Scientific Reports in a paper titled "The Photovoltaic Heat Island Effect: Larger solar power plants increase local temperatures."
This increased absorption, in turn, could increase soil temperatures and lead to greater sensible heat efflux from the soil in the form of radiation and convection. Additionally, PV panel surfaces absorb more solar insolation due to a decreased albedo 13, 23, 24.
On the other hand, cold temperatures can initially boost the conductivity and voltage output of solar panels, but prolonged exposure to extreme cold can result in decreased sunlight availability, increased resistive losses, and reduced panel efficiency. To mitigate the effects of temperature on solar panel efficiency, certain measures can be taken.

Environmental factors critically affect solar PV performance across diverse climates. High temperatures reduce solar PV efficiency by 0.4–0.5 % per degree Celsius. Dust can reduce PV output by up to 60 %, especially in desert regions. Terrain factors like albedo and snow present mixed effects on PV energy generation.

As the temperature of a PV panel increases above 25°C (77°F), its efficiency tends to decrease due to the temperature coefficient. The coefficient measures how much the output power decreases for every degree Celsius above a reference temperature (usually 25°C). Higher temperatures cause the semiconductor materials in photovoltaic cells to become more …

But here''s the catch: as much as they love soaking up the rays, high temperatures are actually a buzzkill for their efficiency.
When utility-scale PV systems are located near urban centers, increased solar absorption of PV fields compared to surrounding terrain is observed which can warm the ambient air, increase ambient temperatures in the nearby cities, as well as in peri-urban and suburban areas .

Solar panels can actually increase the temperature in urban areas during the day. This happens because they absorb a lot of sunlight, which can warm the surrounding environment. Here are some key points: Solar panels absorb about 90% of the sun''s energy. They convert only 16-20% of that energy into electricity.
A typical crystalline silicon solar panel might lose 0.3% to 0.5% of its efficiency for every 1°C increase in temperature above 25°C. On a hot summer day where panel temperatures might reach 60°C (140°F), this could translate to a 10-15% decrease in power output compared to the panel''s rated efficiency.
