Does Solar Panel Temperature Coefficient Matter?
If you are trying to maximize the amount of energy that your solar panel system can generate, then your solar panel’s temperature coefficient is something that you want to be familiar with. Your solar panel’s temperature coefficient has to do with the influence that the panel’s temperature has on its productivity.

Solar Panel Temperature Coefficient
The temperature of your solar panel has a direct effect on its ability to generate electricity. This has to do with the laws of thermodynamics and how heat limits any electronics ability to produce power.

For solar panels, this impact is reflected through the temperature coefficient, which is expressed as the percentage decrease in output for every 1 degree celsius (°C) increase in temperature from 25°C (77°F). Solar panels are tested for their efficiency at 25°C, and that is why this is used as the reference point.

Does is Matter For your solar project ?
A solar panel’s temperature coefficient is not the only factor that influences a panel’s overall power output, but it is a good starting point for calculating a more realistic level of production for your specific setup.

When you are choosing the best solar panels for your project, you can think of how hot your panel may get and use that to estimate how efficient they will be on the rooftop. The good thing is that unless your solar panels are exposed to an exorbitant amount of heat, the decrease in efficiency will likely be negligible, even on a hot summer’s day.

If your roof is designed to absorb a massive amount of heat, and you are also living in a location that can see temperatures of 43°C or higher frequently throughout the summer, the loss will be greater, but still not so severe that it will make a long-term impact on your energy savings.
How to minimize solar panel efficiency loss
Within the scope of the solar panel’s temperature coefficient, the primary way to mitigate loss in efficiency is through the reduction in temperature of your solar panels. Here are some of the factors that influence the panel’s temperature:

The type of solar panel installation has a direct effect on the panel’s temperature. 

The material of your roof can have an impact on the solar panel’s temperature.
Certain rooftops absorb more heat than others.
Make sure to take into account your roof type when making your analysis.
