If
you are interested in the idea of using free, environmentally
friendly energy are in your household and you have a solar panel array
installed, one of the basic requirements that you need to keep track of
the number of solar panels you need.
There are many factors that determine how many you need to use, and how many you would actually be able to buy. Some of these include the results of your energy consumption target calculations (how much energy your household appliances to need to function properly), the budget you have available and the type of solar panel you are using.
Also depends on whether you are considering buying a high-tech solar panels, or you're building your own panels themselves think of cheaper materials, prices may vary. Therefore, the number of solar panels can vary together in a row, and the quality may also be evaluated.
Calculation of energy consumption
If you want to determine exactly how many solar panels you need and want, it is important that the amount of energy that can offer a solar panel and compare it with the value that you need to measure. Given that a normal household about 8000 consumed - 9000 kWh on an annual basis, and the fact that more than $ 300 solar panel of good quality can only be about 100 supply - 200 watt of power, the number of plates to your to power whole house can be quite substantial.
Of course, depending on your needs, you can not always use so much energy on a regular basis. Especially if you are an environmental enthusiast, and you know how to devices that want to provide better functionality, and use less energy, you might actually be able to reduce this number by half, or even less.
Also, if you want to build your own solar panel, you might find that the cost of production effectively be reduced to under $ 200 for a standard 36-cell solar panel. Depending on the quality of your homemade solar power system, you must provide only about 30 or 40 panels to produce enough electricity to power your entire home.
This number can not be too large, but it can be reduced if you want to use an additional form of energy, such as wind power. This can give you more energy on cloudy and rainy days, when solar cells do not work as well, and reduce the need for boards to half or even less.
Be careful how different types of solar cells represents a different amount of energy. You can calculate the energy yield easily, however: after you build your DIY solar panel, measure the current and the voltage it produces, and multiply them to get the value of watts. As a result, a small 6 amp solar panel that produces 12 volts, for example, will provide about 72 watts.
Now, such a weak solar panel not provide you with too much energy, but the good news is that there are many inexpensive modules on the market, the two or more times can provide as much power, and you need not pay more than 300 to 400 dollars for one. A solar system from 10 to 20 of these plates would have done, so are a viable option when it comes to a large number of devices or low-energy house gadgets to the power supply.
Different solar panel types
The speed and efficiency with which solar cells are able to convert solar energy into electricity also plays a role in determining how many solar panels have.
In the case of monocrystalline solar cell plates with, for example, the amount of sunlight is required to produce a given amount of energy, is much less than that of the thin film or polycrystalline cells.
In 2010, a company that provide high quality monocrystalline solar panels manufactured in a position to break the world record for solar-energy-efficiency, production of solar cells that could convert more than 24% of the sun's rays into usable electrical energy.
Some researchers even believe that in a few years it may be possible, monocrystalline solar cells able to go over the 30% or even the 40% mark to create the significant increase in the efficiency evaluation of this type of solar cells, and that of solar energy in general.
A good example of energy efficiency that these solar panels would provide that a solar module with 36 monocrystalline cells can produce about 100 to 130 watts in general. This practically means that if you want to get to 1 kw (1000 watts), you'll need about 10 of these plates. Depending on the quality and brand of the panel prices between $ 3000 and $ 5000 can be for this plan.
In contrast to these results with polycrystalline cell technologies are unlikely to be able to near the limit of 20% today, while thin-film technologies hardly deliver more than 15 to 17% efficiency.
These figures can infer the technological superiority of mono-crystalline PV cells, but does not prove, that the best decision to buy such plates. It is true that you do not know how many panels to achieve a general power of about 1 to 3 kw in this case, but the problem is that the more mono-crystalline solar modules you buy, the greater the difference in price.
You can also opt for less energy-efficiency and better pricing option to save money. In this regard, polycrystalline cells are much better because they are not as weak as thin-film technologies and are slightly cheaper than monocrystalline solar cells.
Budget Themes
Well, everyone is usually thinking about budget problems when it comes to buying or making a solar panel. DIY solar panels are obviously cheaper, but the quality differences can be large, not to mention that you need to put into it a lot of work if you want to run your new panels properly.
When you buy a solar panel to decide on the other hand, you are already all the necessary figures on how many watts it produces, and how stable it is. Through some simple math, you can know exactly how many of these devices, you need to reach your target calculate energy.
The main problem is that there are many brands with a focus on offering different types of solar panels on a large number of different technologies are based. As a result, you may have a hard time choosing between them, and you need to look around at many sites to find out what's behind buyers to think about a particular product.
Most people would believe that about $ 3000 to $ 8000 would be enough for a viable solar panel array, but the numbers could double depending on your needs and the technology you want to use. Fortunately, most manufacturers are already starting to better technologies to develop to buy a more efficient solar cells at a significantly lower price allow.
You have to consider all options, however, and avoid clinging to some brands just because they have a "catchy" marketing agenda. Finally, the numbers will show you everything you need to know and you can have your own opinion about what types of plates you should buy, and how many of them you need.
Summary
You will often find that the company you do business with you can actually with a viable plan when it comes to dealing with the energy consumption and solar panel numbers. Based on your budget and the competence of the solar array that you need, they can often give you an accurate estimate of how much energy you get from your purchase.
Be careful, however, since different brands come at times of new technologies that are cheaper and more effective, and the designs of other companies would seemingly obsolete. You could then recognize the fact that new opportunities can appear at every step of the way.
So if you are thoroughly informed about the factors used, the quality of the technology for the production of panels determine, you will find that you are in a much better position to determine how many need by themselves, without worrying about any to care are unknown factors.
