If you are looking at the concept of using free, environmental friendly energy to power your household, and you need to have a solar panel array installed, probably the most basic requirements you should keep track of is the number of solar panels that you need.

There are many factors that will determine just how many you would need to use, and exactly how many you will actually have the capacity to buy. A few of these are the results of your power consumption target calculations (exactly how much energy your family appliances and devices need in order to function properly), the cost you may have at your disposal and the kind of solar panel you might be using.

Also, depending on whether you are considering purchasing Solceller or you’re considering building your very own panels yourself out of cheaper materials, the values may vary. Therefore, the amount of solar panels it is possible to assembled inside an array could be different, along with their quality might also have to be assessed.

Calculating Energy Consumption – If you wish to determine precisely the number of solar panels you need, it is essential to measure the amount of energy a solar panel can provide, and compare it with the value that you need. Given that a normal household consumes about 8000 – 9000 kwh on the yearly basis, and the fact that a $300 solar panel of excellent quality are only able to provide about 100 – 200 watts of energy, the amount of panels you should power your complete home may be quite substantial.

Needless to say, according to your requirements, you may not always have to use up so much energy on a regular basis. Particularly if you are an environmental enthusiast, and you are aware how to choose appliances that offer better functionality, while consuming less energy, you could actually have the ability to reduce that number to half, or even less.

Also, if you want to construct your own solar panel, you might find that this manufacturing costs can effectively be reduced to under $200 for a standard 36 cell solar panel. Depending on the quality of the homemade solar array, you only need about 30 or 40 panels to offer enough power to your entire home.

This number can still be too big, but it can be reduced if you would like use an additional type of energy, like wind power. This can give you more energy on cloudy and rainy days, when solar panels don’t operate as well, and lower the need for panels to half or even less.

Be cautious, as different types of solar cells can provide a varying quantity of energy. You are able to calculate the energy output easily, however: once you construct your DIY solar panel, look at the current and voltage it generates, and multiply them to get the watt value. Consequently, a small, 6 ampere solar panel which produces 12 volts, for instance, will offer you about 72 watts.

Now, such a weak solar panel may well not provide you with a lot of energy, but the great thing is that we now have many inexpensive panels on the market that may offer several times just as much power, and you don’t must pay a lot more than 300 to 400 dollars for just one. A solar array manufactured from 10 to 20 of such panels would, therefore, represent a viable option when it comes to powering a large number of low energy appliances or gadgets.

Different Solar Panel Types.

The pace and efficiency in which solar cells have the ability to transform solar energy into electricity also plays a part in determining the amount of solar panels you will require. When it comes to panels using monocrystalline solar cells, for example, the volume of sunlight needed for establishing a specific amount of energy is significantly lower than with regards to thin film or polycrystalline cells.

During 2010, an organization that produces good quality monocrystalline solar panels managed to break the world record for solar energy efficiency, producing solar cells that may transform a lot more than 24 % from the sun’s rays into usable electrical power.

Some researchers even take into consideration that, in a couple of years, it may be possible to create monocrystalline solar cells that are able to go beyond the 30 % or perhaps the 40 % mark, significantly enhancing the efficiency rating of these sorts of solar cells, and that of solar energy in general.

An excellent illustration of the power efficiency that these solar panels can provide is that a solar panel employing a total of 36 monocrystalline cells can generally produce around 100 to 130 watts. This practically implies that if you wish to get 1 kw (1000 watts), you will want about 10 of such panels. Depending on the quality and make of the panel, pricing can vary between $3000 and $5000 for this particular plan.

In contrast with these results, technologies using polycrystalline cells are barely able to get near to the 20 % limit today, while thin film based technologies hardly provide about 15 to 17 % efficiency.

These numbers may conclude the technological superiority of monocrystalline PV cells, nevertheless they usually do not prove that the best decision is to buy such panels. It’s factual that you will not need as much panels to reach an over-all production of about 1 to 3 kw in cases like this, but however , the better monocrystalline solar panels you purchase, the greater the price difference becomes.

You may even choose less energy efficiency as well as a better pricing option in order to save money. In connection with this, polycrystalline cells are much better, since they are less weak as thin film-based technologies, and therefore are somewhat less expensive than monocrystalline solar cells.

Budget Issues – Now, everyone is usually thinking about budget issues with regards to buying or manufacturing a solar panel. DIY solar panels are obviously cheaper, however, the standard differences can be great, not to mention that you will need to put lots of work with it, if you would like your brand new panels to do properly.

If you opt to get a solar panel, on the contrary, you may curently have all of the numbers necessary regarding how many watts it produces, and exactly how stable it is actually. By using some simple math, you may then calculate exactly what percentage of these products you will need so that you can meet your energy target.

The main problem here is there are many brands focusing on offering various kinds of solar panels based upon a lot of different technologies. Consequently, you could have trouble choosing between them, and you will need to browse around on numerous websites to discover what past buyers think about any particular product.

Many people would believe that about $3000 to $8000 could be enough for a viable solar panel array; however, the numbers might double based on your needs and the technology you want to use. Fortunately, most manufacturers happen to be beginning to develop better technologies that enable people to buy more effective solar arrays in a considerably discounted price.

You have to take all of the options into account, however, and avoid clinging to some brands given that they use a “catchier” marketing agenda. Ultimately, the numbers will highlight all that you should know, and you may oqepmz increase your own mind regarding which varieties of panels you should get, and how many of them you will require.

Summary – You will often discover that the organization you do business with might actually offer you a viable plan in terms of working with energy consumption and solar panel numbers. Based upon your financial budget as well as the proficiency of the solar power array you need, they are able to often offer you a precise estimate of how much energy you will get from your purchase.

Be cautious, however, since various brands may at times develop technologies that are cheaper and much more effective, and will make the designs of other companies seemingly obsolete. You might actually realize then that new opportunities can appear at every step of the way.

So, in case you are thoroughly informed concerning the factors that determine the quality of the technology utilized for manufacturing panels, you will see that you might be in a much better position to build how many of them you need yourself, without having to be worried about any unknown factors.
