Photovoltaic cells for sale

Photovoltaic cells (PV) are commonly known as Solar cells. Which means use of the most abundantly available source of Nature will give you the energy to lead a luxurious life with least cost. But how or why is it even possible or is it that easy for all people to have access to it? Or is it really that cheap?

Before you start thinking about using Solar Power, you should know a little about how it works .Now the source for Solar cell is Sun – in even simpler word the energy from sunlight converted directly to electricity. You must have seen Solar calculators with no OFF button on it, that is a miracle of Photovoltaic Cells present in it. That is a simple example of a daily household product that you might use. But this Solar cell is used for even bigger operation like the one at Nellis Air Force Base in Nevada. A module is a group of sales connected electrically and packed into a frame commonly known as Solar Panel, which can then be grouped into larger solar arrays to create enough energy for the whole Air Force Base In Nevada.

 Photovoltaic Cells are made of a material called semi conductor like silicon. So when the LIGHT strikes the cell it, a portion of it gets absorbed into the semi conductor. That means the energy of the light is now trapped into the semiconductor material. Thus, the energy let the electrons loose, allowing them to move freely.

There you now have a basic idea about how this works. Now, comes the challenging part. You have now known that this whole process involves the most natural source and that is Sun. So, Sunlight is free, so why not solar power? It should be the cheapest of all. In reality it is not that cheap either. It will cost you some money. It might be less that regular electric circuits system, but here are lots of factors that must be considered in the process.

First factor is where is your Home? If you are living in the sunny side of the world then you might have an advantage than people residing in a less sunny side of the world, as you photovoltaic cells totally depend on Sunlight. With more sun available it can create more energy and in process more electricity. Along with that the cost of utility become a factor for this. Different places have different rates for the utility, thus varying the electricity rates from place to place. So, for someone staying in the North side of the world might still want to go for Solar, because of the increasing Electricity Rates in their area.

Another factor that might affect the Solar Power is the Orientation of the roof of your house. This means the Inclination of roof. Proper inclination in required absorbing the maximum Sunlight to give you most efficiency. Photovoltaic (PV) system in the Northern hemisphere must face south. Solar panel should be inclined at an angle as close as the altitude of the area for their maximum energy year around. Though these modules should never be covered with tress or with tall building around no matter how powerful the Sun is or the time of the day. So, solar panel works best for Household in the open areas or countryside.
But if you have south facing, non shaded roof then you need to decide the size of panel that need to be used because your electricity production actually depends on your weather. Now, weather is unpredictable too and Electricity demands vary too. You should design it for worst month, so that you have enough to consume year around.Even you will also have to decide on the system voltage, which you can control by deciding how many modules to wire in series.

Next comes the Installation cost. Now, to set up a Household photovoltaic system, as per National Renewable Energy Laboratory, the installation cost might range between $8 and $ 10 per watt. It can be said like, the lager the installation required to set up the field, the lesser the cost per watt. Even though, with full installation of the Solar panel, many Solar Power systems do not guarantee you 100% cover for the electricity for the house hold.

The idea of solar power is an old concept, though since 1954 it has been introduced as the modern age of solar power. After this concept came into the market people have tried to improve it for better efficiency. Once you hit the market you will find many solar cells or photovoltaic cells for sale. You will find them online or offline. In case of infrared capable photovoltaic cells, cost depends on the cost per watt in 24 hours. As heard, some engineers did make solar cells with a chemical compound called germanium that reduces the cost.

If people can really increase the use of Solar cells it will reduce the cost of electricity in your family and help run a House at lot cheaper. Any average household consumes power ranging between 3 to 5 KW, but if used reasonably then it might only consume around 1 KW, which in return in enough to run a TV, DVD, Microwave and other ordinary household appliances.

Any household requires about $ 15,000 to $25,000 to set up any electrical circuit, whereas Photovoltaic panel will cost between “ $9,000 to $ 15,000”. Even you will be saving on the consumption of electricity for the rest of you life.

You can definitely buy the required material online. Now with this increased demand even many stores have them and they specialize in Solar (PV) panels. Some brand names also have solar panel or photovoltaic cells for sale – Samsung, BP Solar, General Electric (GE), Sharp and Sanyo. They are manufacturers with good quality products and unbeatable recommendations. There are other manufacturers also who only deals with Solar panels.

Every person in this world will be more than excited if Solar (PV) cells can really be a part of our family. It will make a healthy environment and also support an economical life style. May be that is the World we are looking forward to.
