Solar panels are designed to resist severe temperatures. Therefore it is doubtful that they will ever get too hot to work. However, there are still some heat-related factors that may affect the overall efficiency and energy production of your solar panels.
What is the maximum temperature that solar panels may reach, and how does this affect my system?
Heat reduces the energy production of solar PV modules by a small amount, measured by the panel’s temperature coefficient. We’ll look at how temperature impacts solar panel efficiency and output and why Tier 1 solar panels are a solid investment in this post.
What is the ideal temperature for solar panels?
Like any other electrical equipment, solar panels perform best when the temperature is kept as low as feasible.
Solar panels are measured at 25 degrees Celsius (77 degrees Fahrenheit) with 1,000 watts of light per square meter shining on them to determine their rated maximum output.
While these Standard Test Conditions (STC) are somewhat unrealistic, they are designed to ensure that your panels can produce power under ideal conditions. Most solar panels, for example, are 250-350 watt panels. Thus they should be able to generate 250-350 watts of power under the testing mentioned above circumstances.
The “solar panel max temperature” for most solar panels is quoted at 185 degrees Fahrenheit, which appears to be relatively high. On the other hand, solar panels are hotter than the air around them because they absorb the sun’s heat, and because they are constructed to withstand extreme temperatures, they will not decay.
What does it mean to have a temperature coefficient?
The temperature coefficient is the percentage decrease in energy output for each degree Celsius over 25, or 77 degrees Fahrenheit, in degrees Celsius. It is preferable to have a low-temperature coefficient.
Because the loss in output is so low (about.5%), you won’t notice any difference in the performance of your solar panels.
