What Causes Solar Panels to Overheat?

Most people in Australia, who go for solar power installation Sydney, believe that solar panels in the hottest regions will generate a higher amount of energy. It is true that an abundance of sunshine is vital for energy generation. However, a high amount of heat is bad for solar panels. Too much heat may result in solar panels overheating.

What Happens When Solar Panels Overheat?

  • Just like any other electrical system, solar panels get overheated as well.
  • In the case of solar panels overheating, the temperature of the solar system increases, resulting in a significant reduction in energy efficiency.
  • The solar panels start losing a lot of energy, which otherwise they would have converted into electricity.

What Are The Common Causes of Solar Panels Overheating?

  • When it comes to solar power installation Sydney, there are two factors to keep in mind about sunshine – light and heat.
  • Light is that component of sunshine that is absorbed by solar PV cells in the solar panel to generate DC current.
  • Luminous flux refers to the brightness of light emitted from a source in terms of its energy.
  • Higher the luminous flux, the greater the electricity generated.
  • On the other hand, the heating element of sunshine is detrimental to solar panels.
  • Excess heat negatively impacts the ability of a solar panel (system) to convert sunlight into electricity.
  • To prevent solar panels overheating, it is essential to have a good airflow between the panels and the house roof.
  • If you are planning for solar power installation Sydney, having good airflow is essential for the solar system to keep functioning seamlessly without any overheating issues.
  • A proper airflow also prevents the accumulation of moisture in case of excess humidity.

Do Solar Panels Overheating Cause Permanent Damage?

  • For solar power installation Sydney, solar panels from some of the best manufacturers are available in the market.
  • The manufacturers perform a lot of rigorous testing on the panels before certifying them for use.
  • The quality tests of solar panels involve exposing them to extreme levels of humidity.
  • The temperature testing is also done from plus 85 degrees Celsius to minus 40 degrees Celsius.
  • Only once the solar panels pass the stringent quality checks, they are approved to be sold for solar power installation Sydney.
  • Solar panels are designed and manufactured to withstand extreme weather and climatic conditions.
  • Excess humidity and heat can reduce the efficiency of the solar panels.
  • However, it is unlikely that overheating will result in permanent damage.

Warning Signs of Solar Panels Overheating

  • Energy efficiency of the solar panels reduces drastically
  • Temperature of the solar system is higher than the normal range
  • Thermal losses
  • Reduced power output

Solar panel overheating is definitely possible and results in a decline in the performance and efficiency of the solar module.
