1. Do solar panels reflect heat?
First of all, the answer to this question is yes, although most of the light will be absorbed by the solar energy and converted into electricity when it hits the solar panel, you need to know that when the solar panel absorbs and converts the sun’s rays, the panel material does not absorb certain wavelengths of the sun’s light completely, which will reflect this part of the heat out, so the solar panel will also reflect the heat. .
It is worth mentioning that this phenomenon of reflecting heat basically exists in the entire natural world, and solar panels can absorb most of the heat carried by the light, and will only reflect a small part of it, so you do not need to be too concerned.
According to the actual data surface, the installation of solar panels around the home temperature will be lower than the home without solar panels, which is due to the vast majority of the sun’s rays are absorbed by the solar panels, and only a small portion of the heat is reflected out of the result, so the installation of solar panels will not lead to the temperature of your neighbourhoods due to solar panels reflecting the heat and rise.
2. Is there any way to reduce the heat reflected from solar panels?
(1) Apply anti-reflective coating on the surface of solar panels
There is a special type of anti-reflective coating, called ARC, because this type of material usually has a very low refractive index, so this type of special anti-reflective coating on the surface of the solar panel can effectively reduce the reflection of light, so that more light enters into the interior of the solar panel, and thus reduce the solar panel on the reflection of heat, so it can be applied on the surface of the solar panel anti-reflective coating is a good way to reduce the reflection of heat. Thus, applying anti-reflective coating on the surface of solar panels is a good way to reduce heat reflection.
(2) Texturizing the surface of solar panels
Texturizing refers to the manufacture of tiny textures or grooves on the surface of solar panels, such texturizing can make the sun’s rays refracted many times on the surface of solar panels, which compared to solar panels without texturizing, these textures can effectively avoid the direct reflection of light, increase the absorption of light by solar panels, and thus reduce the heat reflected by solar panels.
(3) Optimize solar panel materials
Different solar panel materials have different absorption capacity of the sun’s rays, the use of light absorption capacity of the material can improve the overall light absorption rate of the solar panel, and thus reduce the heat reflected by the solar panel. With regard to the common solar panels on the market today, monocrystalline solar panels have the highest light absorption rate, and you can choose to use monocrystalline solar panels to minimize the reflection of heat.
(4) Thermal Management System
Thermal management system can not directly reduce the solar panels to reflect heat, but through the thermal management system can reduce the overall temperature of the solar panels, which can not only make the solar panels run efficiently, strengthen the absorption and conversion of light, and thus reduce the reflection of heat, but also effectively reduce the heat emitted due to the rise in the temperature of the solar panels themselves.
(5) Light trap design
Light trap design refers to the creation of multiple reflections inside the solar panel, so that the path length of light in the semiconductor material will increase, in order to increase the absorption rate of light on the solar panel, so that the solar panel will reduce the reflected heat, so the choice of solar panels that have been designed for light traps is a good way to reduce the reflected heat from the solar panel.
(6) Adding a tracking system for solar panels
A tracking system for solar panels ensures that the solar panels remain in a perpendicular position to the sun’s rays, in this way, the light can enter the interior of the solar panels well, which in turn is absorbed by the solar panels, so the heat reflected by the solar panels is naturally reduced, so adding a tracking system to your solar panels is a good way to reduce the heat reflected by your solar panels.
(7) Regularly clean the surface of solar panels
As solar panels work outdoors for a long time, the surface of solar panels will be attached with a layer of impurities, such as dust, which will affect the absorption of light by solar panels. Therefore, you should clean the surface of your solar panels on a regular basis, so that the solar panels can work efficiently, and thus reduce the reflection of heat, which is something you should pay attention to.
3. In conclusion
Solar energy irradiation on the solar panel will inevitably emit heat, the best working temperature of the solar panel in 25 ℃, so in the hot summer is not the highest efficiency of the solar panel is the spring and autumn, in the summer to reduce the temperature of the solar panel can effectively improve the efficiency of the solar panel, solar panels reflecting heat on the surrounding buildings do not have much impact on the most important is the solar panel! The solar panel itself, by optimizing the solar panel material, surface treatment and tracking, thermal management system is a good way.
