The vast majority of us are aware of the existence of solar panels, which convert sunlight directly into electricity through the so-called photoelectric effect.
But what if I told you that there is such a thing as solar panels at night? In this article we will tell you a little about them.
LET'S TALK ABOUT PANELS
Technology is constantly increasing its potential and improving day by day, and it is not lagging behind when it comes to solar energy. Solar panels, as mentioned above, are responsible for converting sunlight into energy, even at times when radiation is at its lowest.
These panels have many advantages for the reduction of environmental pollution. They generate low greenhouse gas emissions and are a type of renewable energy, since the sun's energy is unlimited in practical terms. The major disadvantage is that these panels are not effective when it is raining, cloudy or dark. Therefore, technology is working day after day to solve this problem, creating solar panels at night, which are becoming more and more popular.
SOLAR PANELS AT NIGHT
These night panels have been developed to generate electricity at night. They are still under development, as they are not yet fully effective enough to be launched on the market. However, the fact that these first steps have already been taken is a huge achievement, as a few years ago this idea seemed unattainable.
But how exactly do they work?
Conventionally, a solar power system harnesses ultraviolet radiation. On the other hand, the nocturnal energy system relies on the infrared radiation emitted by the panels at night and the outside air temperatures when the sun is not shining.
Throughout the night, the solar cells radiate infrared radiation (heat), so that their temperature is somewhat lower than outside. The thermoelectric module therefore exploits this temperature gap to generate energy.
We will be watching the progress of these energy developments!
