The function of a solar cell is very simple. It takes light, and it makes it into electricity. It’s very simple, but that doesn’t mean it is easy. Imagine if you were tasked to create something that could actually do that, most people wouldn’t know where to start. Well, by the end of this article, you’re not going to be an expert in how to build solar panels, but you should at least understand the principles involved.

How Does Light Become Electricity?

To answer this question of how it is that light becomes electricity, we have to be more clear about exactly what light is and what electricity is. There isn’t room to go into detail about this of course, but we can get a general idea.

A Photon

The most important thing to know about light when it comes to solar panels is that it can be viewed in two ways, as being made up of waves and as being made up of particles. In fact both is true, which is a bit strange, but this is something that has come out of quantum physics.

In terms of solar cells, the most useful way to think about light is as being made up of particles of light. That is what a photon is, it is the name for a particle of light. If you’re wondering how light can be thought of as being particle based, in terms of waves it is the smallest packet of waves that you can get (if that makes it any clearer!).

What Is Electricity?

Electricity consists of the uniform flow of electrons in a substance. The substance has to have certain qualities which allows this to happen, they have to be made up in a particular way. When the conditions are right, then we call that material conductive, because it can conduct electricity. This applies to metals mostly.

There is another type of material though which conducts electricity in a slightly different way. It still has to do with the electrons flowing, but this flow can be created by the existence of “holes” in which there should be an electron. This hole will attract an electron, so that is how electricity can flow as well. Substances that do this are called semiconductors.

Solar Cells

With this information, the way that a solar panel actually works can be described more easily. The first thing to know is that they are made of a semi-conductive substance, often silicone. The important thing about this is that when a photon hits the semiconductor which the cell is made of, it pushes an electron out of its orbit and this creates a “hole” in it, like the ones described above. This is what causes electricity to flow.

It’s not quite as simple as getting a semiconductor and hooking it up to some wires though. There are actually two halves, one of which has to be negatively charged and the other half has to be positively charged. In their normal state, these halves are balanced, but when light hits them the balance is upset and that is what makes the electrons move in a uniform way.

How The Solar Electricity Is Made Useful For Your House

A little bit more work has to be done before the electricity can be used in a house though. It comes out as direct current (DC) but houses run on alternating current (AC) so it has to be converted before it can actually be useful.

On the way to the converter, however, it makes a stop in a battery. This is a DC battery, and that’s where the electrical energy from the solar cells are stored, so that it can be used when needed.

Locating The Optimal Solar Power System Installer

If you want to “go green” and save money, then considering solar energy might be a good option for you. Solar power allows people to reduce their monthly electricity bills, while also utilizing the Australian rebate program to make solar system installation more affordable and beneficial. At first, knowing where to begin in order to buy a solar energy system can be intimidating. To help with the procedure, you can hire a professional installer, but there are some aspects you should personally take into consideration before beginning.

The first factor is cost. This is obviously an important factor for many people, but it might not be relevant in the way you think it should. When investing in a solar energy system, it is actually more beneficial to buy a system that may be on the costly side (as long as it has the quality to back up the price). The reason for this is that you “get what you pay for”, and as solar energy systems tend to last for more than twenty years, you will be making a good investment.

A second aspect to look at when finding a solar energy installer is their warranty. As mentioned before, solar systems should reliably work for at least twenty years, and a solar power installer should have a warranty to back this up. The solar panels in a photovoltaic system degrade at 0.5% to 1% a year, but this should still leave you a lot of time to benefit from your renewable energy source. Having a warranty that is actually backed by a company in Australia is also pivotal – in certain instances another country may back the warranty, which means you could end up paying very high postage fees to send them any damaged equipment should something run amiss.

Workmanship is one other important but usually neglected factor. Quality solar systems can be very eye-catching. Your contractor must be able to inform you of what sort of mounting system they often use, and also if they allow air to flow beneath the panels or not. Unprotected cables must be taken note of; they are significantly less able to withstand the temperature of the sun than the panels are, therefore all external wires should be in a UV guarded conduit. You can even ask for recommendations from other clientele and check to see if an installer will show you a selection of their earlier work. A good quality solar technology system needs to be straightforward but effective.

The last thing it’s best to take note of is merely how well you get along with your contractor. Are they really ready to respond to your questions and are they available to help? Confirm they are licensed by the “Clean Energy Council”, because this is quite important. All installers have to have this certification in order for the government to pay out its refunds to you. Should you pay attention to the particulars, you’re definitely halfway to owning a wonderful renewable power system, but make sure your installer is willing to meet you in the middle and support you along the journey.

Are you having a hard time in finding the best solar panel for you? Well I cannot blame you since there are really numerous models of panels rising in the market nowadays. To help you give solution to your problem. Here are some of the Pennsylvania Solar Panels.

The first kind of solar panel is made possible to give answer to the never ending demand of those customers that do not have vast roofs. We all know that the solar panels and its accessories are quite huge that obviously requires vast roof, this only connotes that some people who do not have big roofs will be deprived of having the system installed.

The first models of solar panels somewhat requires a huge roof due to the size of the said device, so inventors have created a new model that will fit into the roof regardless of its size and together with this is the flexibility feature since the older solar panels are known to be brittle, these new features make the solar panel live much longer that before.

Solar Panels especially made for homes. The main purpose why renewable source of energy had been introduced in the market is to encourage the people that there are still a lot of ways that we can make to have a green living. This kind of panel is made easy so that customer can easily deal with it. All you have to do is to look for the spot in your roof where sunlight hits often and there you install your solar panel. Actually most of home owners do not solely depend on this source of power, they use it together with the source of electricity that they used to have so that when winter comes they will still have source of power that can be used.

As the time pass by, we can see that the devices and new technologies get smaller and smaller. Solar panels are not left behind; there is a new model that is showing off in the market that is very tiny and very thin. This is what they call the Nano Solar Panel. Although it is very small, it transmits heat energy from the sun at 20% higher than the amount of energy harnessed by other type of panels.

Pennsylvanians do not let yourself be deprived of this great opportunity. I have provided you some of the best types of Pennsylvania Solar Panels. Make your choice, now!

We cannot deny that scientists and inventors really possess genius minds for they can think of things that we never imagine of being into reality, just like the renewable source of energy. They have thought of something that can replace that burning of fossil fuels as source of energy since in gives of dangerous waste that gives bad effects on the environment. Having this discovery a part of everyday living can be a great help in rejuvenating the beauty of nature.

One of the greatest achievements that they have is the Alternative Energy that has been launched worldwide. Pennsylvania is one of the countries that really patronize this project. Actually there is a lot of Pennsylvania Renewable Energy that they choose from. Allow me to give you a peek on that alternative energy and how it works.

Wind as the source of energy. This kind of energy source makes use of turbines. Turbines actually have three components, the tower, the blades and the nacelle. The last that I have mentioned is the most important part among the three since this is the place where most motion happens; this is where electricity is produced. Wind energy has been used by people since earlier times, but up to now wind energy is not often used as source of power even though it is the cheapest of all.

Water as source of energy, Because of the increasing demand for electricity, scientists has thought of something that is of huge volume and will never run out of stock. And since 70% of earth is made of water, experts decided to us it for better purpose. The process of conversion requires vast volume and high speed water to make the generator works. If the generator turns on the transformation process begins.

Solar heat as source of energy, this is one of the easiest system that consumer can avail of. There are a lot of solar panels available in the market that can be installed by the buyer himself. And also the machines come in different sizes and design that fits the various demands of the customers.

Due to the new invention that the experts have introduced, we all have the opportunity to save our environment, the opportunity to avoid the vast destruction in the future. Pennsylvania Renewable Energy is just one of those opportunities that we can grab. The decision is all in your hands. Make your choice, now.
