This article is going to provide information on solar panels, information regarding how they work as well as the sorts of financial and environmental benefits that you get by using them. This is useful to know if you are considering getting a solar installation or if you would just like to know more about solar energy.
How Solar Panels Work
In this article we're going to be focusing on PV solar panels, the kind that generate electricity. You should also be aware, however, that solar thermal panels also exist, which you can use to provide you with hot water in your home.
When it comes to solar panels information about how the electricity generating solar cells work, it is going to have to come in a basic form. The specificities become very complicated and anyone without a degree in physics would probably find it very hard to follow. In simple terms however, it is quite easy to understand.
The first thing to say is that electricity is the name we give to the energy we get when electrons flow in a material. So the job that solar cells have to perform is to get light striking them to make electrons flow to your house.
The main challenge when it comes to solar energy is to get light and to convert it in to electricity. This is achieved in large part by the material which solar cells are constructed out of. Usually that's silicon, but it could really be any semiconductor as one of their properties is that when light strikes them, electrons move.
Just getting the electrons to move is not enough though, they actually have to flow in a single direction. That's why solar cells have got to be put together in a specific way. The way they are made is that one half is charged positively, and the other half is charged negatively. This means that when the light hits, and the electrons are made to switch sides, they will no longer be in balance.
Nature always likes to restore balance when it can, so we simply provide them with that opportunity by attaching a wire which goes to your house. The electrons flow along this wire, and this of course means that you are getting electricity flowing to your house.
Benefits for the Environment
Whenever anyone gets solar cells installed on their roof they are helping the environment, another important piece of solar panels information. The reason for this of course is because the more renewable energy that is used, the less energy that we get from fossil fuels is required.
When it comes to ceasing using so much energy from fossil fuels, the whole reason that this is so important is because by using fossil fuels we are exacerbating the problems of global warming. The more we use renewable energy then, the less energy we need to get from carbon-emitting fossil fuels.
Financial Benefits
As soon as you start using solar energy you are going to start saving money on your energy bills of course. However to calculate the financial benefits you have to contrast this with the cost of the installation in the first place.
When these are the only two factors involved, then with the current state of technology, it doesn't look very good. It takes a long time with savings alone to pay off the cost of the installation. However that is not the case when you consider the feed in tariff in addition.
The feed in tariff is a government scheme which pays you for all of the solar energy that you produce. You still get to use it as well of course, so that's two ways of making money. With this considered as well, it's a much better deal and means that you pay off the installation costs much sooner.
