Last time we concentrated on the solar automatic gate openers, this time we’ll take a bit of a deeper look into how solar panels work and how to use them in fencing. This time let’s start with finding some good ways to use solar power in fencing and then actually turn to the explanation of how solar panels exactly work.
So…using solar power in fencing. As mentioned before then widely used solar automatic gate openers in Melbourne is no news. But are there any other ways you can use solar power panels in fencing? Let’s see. Hmm..feels like a famous Australian TV show “Pointless” where you try to guess the answer that has been named the least. Hard one as we got the most popular answer out of the way.
1. Solar automatic gate opener for domestic, commercial or industrial usage
2. Solar powered electric fence for livestock
3. Lights for your fence powered by the solar panels
The last one was more for the sake of having that lucky number 3, but in reality it’s good to have lights showing you the way in the dark that are powered by the solar power to save the environment and a bit of your money. But solar automatic gate openers and solar powered electric fences would be our TOP 2.
Now that’s out of the way, let’s look how do solar panels actually work.
Okay! Solar panels! According to Live Science, solar panels allow photons or particles of light to knock electrons free from atoms and thus generating a flow of electricity that way. Solar panels comprise many smaller units called photovoltaic cells. Putting it simply in a human language photovoltaic (Huh! Even typing it is tedious, don’t want to think about pronouncing it!) means that solar panels convert sunlight into electricity. So when you connect the cells together, you get a solar panel.
Anything else we need or should know about solar panels? Yes. Well…no, if you think that your knowledge about the solar panels should stop with knowing that they produce electricity from the sunlight. But that’s just elementary! Let us dig deeper!
Photovoltaic cell is made of two slices of semi-conducting material, which in most cases usually is silicon. To put it simply, for photovoltaic cell to work it needs an electric field, which occurs when opposite charges are separated. This is why silicon used in photovoltaic cell is “doped” with some other materials to create a positive and negative electric charge. This is why you get a “sandwich” that is made out of two slices: one with a negative charge and the other one with positive charge.
If to be precise of what that stuff they dope the silicon with is, it’s phosphorous for the top layer of the silicon to add extra electrons making it a negative charge, and adding boron to the bottom layer so there will be less electrons to make it to have a positive charge, and woilaaa, you have an electric field at the junction between silicon layers. So when your solar panels sees some sunlight, then photon of sunlight knocks the electron free, that electric field created between the silicon layers will ohs that electron out of that silicon junction.
Almost there! Last thing we’re going to mention about the solar panels to finish it off. So electricity has to flow right? And metal conductive plates on the side of the cells collect the electrons pushed out of that silicon junction by the electric field and transfer them into wires and here you go: flowing electrons like any other source of energy.
Here you go! The science behind the solar panels with the help of Live Science.
