- Solar panels make less electricity in hot weather.
- High temperature reduces the voltage of electrons.
- Efficiency is maximum up to 25°C, then gradually decreases.
- Correct condition, cleanliness, quality increases the efficiency of the panel.
Solar Panel Energy Generation: Solar panels are completely dependent on sunlight. They capture sunlight and convert it into electricity. If there is no sunlight then solar panels also do not work. For this reason, many people think that when there is strong sunlight during the summer season, solar panels will also generate more electricity. Actually it is not so. Temperature also affects solar panels. If the temperature becomes high then the efficiency of the solar panel reduces slightly. Therefore, in extreme heat, the energy production of solar panels decreases instead of increasing.
Why do panels produce less electricity in extreme heat?
The answer to this is hidden in science. Actually, in sunlight, the photons emitted from the sun reach the solar panel. Reaching near the solar panel, they create an electric field, due to which electrons start moving and current is generated, which produces electricity. But when the temperature is high, the solar panels become very hot. Due to this, the movement of all molecules including electrons increases. That is, the electrons start moving more than necessary and they are not able to move to the place where they should be. Due to this the voltage reduces and energy production reduces.
Up to what temperature do solar panels work with full efficiency?
Solar panels work at their full efficiency up to 25 degrees Celsius. After this, as the temperature increases, the efficiency decreases by 0.5 percent with every degree. That means, if the temperature reaches 45 degrees, the efficiency of the solar panel can reduce by 10 percent.
How to increase efficiency?
For maximum efficiency of the solar panel, it is important to have the correct position of the panel. Solar panels should always be south facing, so that maximum sunlight can be captured. Similarly, it is also necessary for the panel to be clean. If the panels are dirty, there can be a reduction of up to 15 percent in energy production. Choose high quality panels for maximum efficiency. Even though their cost is high, they have a longer life span and will be able to generate more electricity.
