If you are interested in the concept of using free, environmental friendly energy to power your household, and you want to have a solar panel array installed, one of the most basic requirements you need to keep track of is the number of solar panels that you need.
There are many factors that could determine exactly how many you should use, and exactly how many you will actually have the capacity to buy. Some of these are the outcomes of your power consumption target calculations (just how much energy your household appliances and devices need to be able to function properly), your budget you might have at your disposal and the type of solar panel you happen to be using.
Also, based on if you are considering purchasing Solceller or you’re thinking of building your own panels yourself out of cheaper materials, the prices can vary. Therefore, the number of solar panels you can assembled in an array might be different, and their quality might must also be assessed.
Calculating Energy Consumption – In order to determine precisely the amount of solar panels you need, it is very important measure the amount of energy a solar panel will offer, and compare it with all the value that you want. Considering that an ordinary household consumes about 8000 – 9000 kwh on the yearly basis, and the truth that a $300 solar panel of excellent quality could only provide about 100 – 200 watts of energy, the number of panels you need to power your whole home may be quite substantial.
Of course, based on your needs, you might not always need to use up a great deal energy regularly. Particularly if you are an environmental enthusiast, and you understand how to pick appliances which provide better functionality, while consuming less energy, you may actually have the capacity to reduce that number to half, or perhaps less.
Also, if you wish to construct your own solar panel, you can definitely find that the manufacturing costs can effectively be reduced to under $200 for any standard 36 cell solar panel. Depending on the quality of your own homemade solar array, you only need about 30 or 40 panels to offer enough power for your entire home.
This number can still be too big, but it could be reduced if you would like use an additional form of energy, including wind power. This can offer you more energy on cloudy and rainy days, when solar panels don’t operate too, and lower the necessity for panels to half as well as less.
Exercise caution, as several types of solar cells will provide a varying quantity of energy. It is possible to calculate the vitality output easily, however: after you develop your DIY solar panel, look at the current and voltage it creates, and multiply them to get the watt value. Consequently, a tiny, 6 ampere solar panel which produces 12 volts, for example, will offer about 72 watts.
Now, such a weak solar panel may well not present you with too much energy, but the good thing is that there are many inexpensive panels on the market that can offer 2 or more times as much power, and you also don’t need to pay greater than 300 to 400 dollars for starters. A solar array manufactured from 10 to 20 of these panels would, therefore, represent a viable option with regards to powering a huge number of low energy appliances or gadgets.
Different Solar Panel Types.
The rate and efficiency with 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 need. In the case of panels using monocrystalline solar cells, for instance, the volume of sunlight required for generating a specific quantity of energy is way under with regards to thin film or polycrystalline cells.
During 2010, a business which produces good quality monocrystalline solar panels could break the world record for solar energy efficiency, producing solar cells which could transform a lot more than 24 % of the sun’s rays into usable electrical power.
Some researchers even take into consideration that, in a few years, it could be possible to create monocrystalline solar cells which will go beyond the 30 % or maybe the 40 % mark, significantly improving the efficiency rating of these types of solar cells, and this of solar energy generally.
A good demonstration of the vitality efficiency that these particular solar panels can provide is a solar panel employing a total of 36 monocrystalline cells can generally produce around 100 to 130 watts. This practically means that in order to get 1 kw (1000 watts), you will require about 10 of these panels. Depending on the quality and make of the panel, pricing may range between $3000 and $5000 for this particular plan.
In contrast by using these results, technologies using polycrystalline cells are barely able to find close 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, however they do not prove the best decision is to purchase such panels. It’s factual that you simply will not need as much panels to arrive at an over-all output of about 1 to 3 kw in this case, but the problem is that the greater monocrystalline solar panels you purchase, the greater the price difference becomes.
You may even choose less energy efficiency along with a better pricing option to avoid wasting money. In this regard, polycrystalline cells are significantly better, because they are much less weak as thin film-based technologies, and they are somewhat less expensive than monocrystalline solar cells.
Budget Issues – Now, most people are usually considering budget issues when it comes to buying or manufacturing a solar panel. DIY solar panels are clearly cheaper, however, the standard differences could be great, in addition to that you will need to put a lot of work into it, if you wish your brand-new panels to perform properly.
If you choose to get a solar panel, on the contrary, you may curently have all the numbers necessary regarding the amount of watts it creates, and just how stable it really is. By utilizing some simple math, after that you can calculate exactly how many of these devices you will need so that you can meet your energy target.
The primary problem the following is there are many brands centering on offering several types of solar panels based upon a huge number of different technologies. As a result, you may have a hard time choosing between them, and you will have to check around on numerous websites to learn what past buyers consider any particular product.
Many people would believe that about $3000 to $8000 would be enough to get a viable solar panel array; however, the numbers might double based on your needs and the technology you would like to use. Fortunately, most manufacturers are already starting to develop better technologies that allow men and women to buy more effective solar arrays at a considerably discounted price.
You need to take all the options into account, however, and get away from clinging for some brands since they possess a “catchier” marketing agenda. Ultimately, the numbers will reveal all that you should know, and you could oqepmz your own mind regarding which varieties of panels you should buy, and what number of them you will require.
Summary – You will sometimes find 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. According to your finances and the proficiency from the solar power array you want, they could often offer you a precise estimate of how much energy you can get from your purchase.
Be cautious, however, since various brands may occasionally develop new technologies which are cheaper and more effective, and would make the designs of others seemingly obsolete. You could actually realize then that new opportunities can be shown at every step of the way.
So, in case you are thoroughly informed concerning the factors that determine the standard of the technology used for manufacturing panels, you will see that you are in a much better position to determine what number of them you require yourself, without having to concern yourself with any unknown factors.
