How does the solar system work?
Are you new to the solar system? Curious to know about its working? Such curiosity is common when you get to know new things about the solar system. So, the main question is how does the solar system work? Is the working same for the residential and commercial solar system?
Well, the working of the solar system depends on the sun’s energy i.e heat and light which otherwise is called radiation. As discussed earlier, once the sunlight covers the solar panels it generates electricity. These panels are designed to absorb the sun’s light in any condition. Be it the rainy season, windy weather, winters or snowfall, solar panels can work in any condition.
How is this possible since the solar system is connected to the sun? Is solar energy-efficient for solar panels to work? Yes, the solar system is connected to the sun and solar energy is efficient for solar panels to function.
Take for example it is a cloudy day during the afternoon hours, but still, there is light, isn’t it? It’s not that you can’t see anything or it’s turned completely dark. This is because the sun is already present in the sky only the clouds have covered it. Even if the clouds cover the sunlight the reflection of the sun is enough to get the light and also for the working of solar panels.
So, this is how solar panels work even in extreme climate. Moreover, with solar batteries, you can even save energy to use it later. This is an extra benefit along with other advantages of the solar system.
