In an age where fossil fuels are in rapid decline, it seems clear that the future is solar. Several countries now run almost entirely on solar energy, whilst major players like the US, China, and India have increased their solar energy output more than tenfold in the last decade.
You may be familiar with the newsreel images of shiny solar panels glaring away in the desert, but how much do you actually know? Few people are aware of exactly how solar energy works, and the multitude of benefits that come with it.
If you want to get a better understanding of what the future of energy truly looks like, then read on to find out how does solar energy work.
How Does Solar Energy Work? The Science Part.
Put simply, solar energy harnesses to vast energy emitted from the sun to generate electricity. It is estimated that more energy from the sun reaches the Earth every hour than all of humanity uses in a whole year.
Therefore, it’s important to put that energy to good use. A solar panel directly converts the energy from the sun into useable electricity. It does this by allowing particles of light (photons) to knock electrons free from atoms. This process generates a steady stream of electricity.
This process is instant and continuous. It is a much more straightforward process than, say, the conversion of coal into electricity.
How Do Solar Panels Work?
So you know the basics of how solar power works, but what about the panels that fuel it? Solar panels are made of solar cells, which themselves are made out of silicon. These cells have both a positive and negative charge like a battery, which creates electricity.
So how does solar power work in the long run? Your average solar panel lasts anything between 25 and 45 years, with barely any maintenance needed to keep them going. Investing in solar is a lifelong guarantee.
What About When It’s Not Sunny?
Many people who aren’t aware of how does solar power works assume that once the clouds appear, that means no more energy.
Clouds may not be ideal for solar energy, but they aren’t fatal. Solar power works just fine when the sun is hidden behind clouds and rain, albeit at a slightly reduced capacity. Many countries such as the UK, Germany, and France, all famously overcast countries, generate huge amounts of solar energy.
What’s more, you can also store up and save solar energy for later use. Taking advantage of a Solar Generator allows you to stock up on solar energy when the sun is shining, for you to use on a rainy day.
You can even use personal, portable solar generators to harness energy from the sun wherever you go.
Solar energy is one of the most powerful tools we have for fighting climate change. It’s important that everyone understands the benefit it can have and the future of solar energy is bridge for us.
