The promotion of solar energy has seen more and more people installing solar panels in their homes. Solar panels can produce enough electricity for our use when there is plenty of sunlight. However, when the sunlight is scarce, the power generated by solar panels will not be enough for us to use. Have you ever thought of using the light from a flashlight to generate electricity from solar panels? Can solar panels really generate electricity this way? Here we will take you to explore this question.

Can solar panels work with the light from a flashlight?

Yes, it is possible to make solar panels generate electricity using both flashlight light and sunlight. In fact, you only need to understand the principle of solar panels’ power generation to understand it. However, the general purpose of flashlight light is for illumination, so their light intensity is relatively mild, for the solar panel power generation efficiency will be extremely low, if you want the solar panel to use the light from the flashlight can generate electricity efficiently, then the flashlight light intensity should be strong enough, and generally only LED lights and fluorescent can make the solar panel power generation.

Solar panels use flashlight light to generate impacts

Waste of resources: even very efficient LED lights will waste a certain amount of electricity and then converted into light energy, and most of the solar panel photoelectric conversion rate of 15% to 20%, which means that the solar panel using flashlight light work will not only be the original loss of electricity will also be photoelectric conversion loss. This solar panel using flashlight power is far less than the amount of power consumed, completely meaningless.

Cause light pollution: solar panels can work with flashlights, such flashlights for solar panels can produce a certain amount of electricity, but at the same time will also cause light pollution. Light pollution can seriously affect the natural life of animals and damage the local ecological environment. When someone is driving through this kind of photovoltaic station, it may cause the owner of the car to be blinded for a short time, and traffic accidents may occur directly. If this kind of light pollution is then emitted through the glass curtain wall or the coating of the wall, it will also produce even more serious light pollution, affecting the normal life of people in the neighborhood.

What is the difference between sunlight and the light produced by a flashlight?

Difference in light intensity: sunlight is produced by nuclear fission due to solar energy, flashlight light is produced by people to simulate the process of natural light. Generally speaking, for example, on a sunny day that kind of sunlight intensity of light, flashlight is simply not able to produce. The electricity generated by solar panels using light from a flashlight is inherently less than sunlight.

Spectral difference: the sun’s spectrum is very rich, including a variety of wavelengths of light, so that the sun in our eyes can almost be said to be transparent, but for the flashlight light spectrum is relatively single, there will be a specific spectrum of the missing, can not cover all the spectral components of the sun, resulting in flashlight light is relatively mild. And the flashlight’s spectral irradiance fluctuates violently, even with the same light intensity as the sun, using the light of the flashlight to make solar panels to generate electricity will be extremely unstable.

Conclusion

Solar panels can use flashlight light, but the power generation efficiency will be very low, and if it is to be used on a large scale, it will cause a serious waste of resources and destroy the balance of the ecosystem, and it is not recommended to use it.
