Various cooling methods have been developed to keep solar panels cool and operate optimally to mitigate the negative impacts of high temperatures. One of the simplest passive cooling methods involves positioning solar panels strategically to maximize shade during the hottest parts of the day.
Effective cooling methods for solar panels are essential to maximize energy production and extend panel lifespan, resulting in a higher return on investment (ROI). Factors like sunlight intensity, location, and panel materials influence panel temperature and performance, making temperature control crucial.
The most obvious way to cool a solar panel would be to use the same methods that we use to cool anything else: air conditioning, water, refrigeration, etc. The problem with these methods is that there must be a balance between the energy that each system uses versus the amount of extra production that you’ll get from the system.
Even if the summer temperatures were to creep towards boiling point, the reduction in power output would be only around 20% (assuming other conditions remain constant), according to Solar Energy UK. Solar panels become slightly less efficient with every degree they heat up beyond 25°C.
This patterned layer helps cool the panel by redirecting some of the thermal radiation responsible for heating the panels up in the first place. Their experiments, although only in a lab setting at this point, were able to show a 23-degree reduction in the temperature of the cells.
While extreme heat can reduce a solar panel’s efficiency, they continue to function effectively, even in high temperatures. In the UK, around 40% of a solar panel system's energy is generated in the summer, showing its strong performance in warmer months.

Does Solar Panel Cooling Boost Output? (+Video)
This increase means that on a hot, 90-degree summer day your solar panels are sitting at closer to 180-degrees. Wow. Because solar panels tend to lose about .46 percent of power per degree Celsius above their standard test conditions, this will equal up to a 10-25 percent power loss to your solar panel output.

Do solar panels get hot in summer? Understanding the impact.
Summer has more daylight hours. However, high temperatures can lower solar panel efficiency. An average solar panel loses 0.3% to 0.5% of its efficiency for each degree Celsius above 25°C (77°F). This implies that we could observe a discernible decrease in efficiency on hot summer days when temperatures reach 150°F or above.
