If you ask most people, they would probably agree with the idea that putting a solar panel array in the hottest parts of the word that get the most sunshine is the best way to generate the most energy. Although its true that an abundance of sunshine is ideal for generating a lot of power using photovoltaic panels, too much heat can be a bad thing. If solar panels get too hot, they can in fact overheat. Once a solar panel overheats, its efficiency drops drastically, making it lose a lot of the energy it would otherwise gather from the sun.
What Causes Solar Panels to Overheat?
When we think about sunshine we often think about two main factors; heat and light. These factors are very much in play when it comes to designing and installing a solar panel array that is made to harness solar energy in the most efficient way possible. The light component of sunshine is essentially what a PV panel is designed to capture and use to produce electrical energy. Meanwhile, the heat element of sunshine can be detrimental to this process.
Let’s think about a typical solar panel array found on top of a home with a sloped roof. In order to prevent heat from reducing the efficiency of the PV system, it is essential for the panel array to have good airflow between itself and the roof of the house. It is also important for any solar panel system to have good airflow in order to reduce exposure to moisture caused by humidity. It goes without saying that moisture and electrical currents are not a good combination, but in addition to being a safety hazard, moisture in your solar system can wreak havoc on its efficiency.
Can Heat Cause Permanent Damage?
Solar panels go through a lot of rigorous testing before they are certified for use in a solar system. They are exposed to extreme levels of humidity as well as extreme heat and cold ranging from 85 degrees Celsius to negative 40 degrees. Once they pass these intense tests, they are deemed suitable for sale and installation. Owners can rest assured that their solar panels will be able to stand up to even the worst weather conditions without breaking. Although heat and humidity can do a lot to reduce the efficiency of a solar panel system, it is virtually impossible for a solar panel to be damaged by heat and humidity alone.
