While sunny warm days seem to be best for solar energy generation, silicon PV panels can become slightly less efficient as their temperature rises. This is due to a property of the silicon semiconductor, which means that these class of Solar PV panels have a ‘negative coefficient of temperature’: this means they produce less energy when really hot.
The overall power coefficient is negative, indicating decreased efficiency at higher temperatures. Contrary to what one might expect, solar panels actually become less efficient as they get hotter. This inverse relationship between temperature and efficiency is due to the physics of how solar cells work.
As surprising as it may sound, even solar panels face performance challenges due to high temperatures. Just like marathon runners in extreme heat, solar panels operate best within an optimal temperature range. Most of us would assume that the stronger and hotter the sun is, the more electricity our solar panels will produce.
So, while cooler temperatures are actually better for solar panel production, the warmer regions make up for their heat with extra sunshine. Cooler regions tend to be at slightly less advantageous angles from the sun and the equator but make up for it in great efficiency when the sun is shining.
It’s a range for the temperatures at which a panel can produce at its best. Here’s an example. A 200-watt panel at 20 degrees Celsius (68 degrees Fahrenheit) might only produce 180 watts when the panel reaches 45 degrees C (113 degrees F). The ideal day for a solar panel is actually cold, sunny and windy.
When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F). Panels with a lower temperature coefficient, closer to zero, perform better in high temperatures.
