If you are considering the thought of using free, environmental friendly energy to power your household, and you would like to have a solar panel array installed, one of the most basic requirements you should keep an eye on is the number of solar panels that you require.
There are numerous factors that would determine just how many you should use, and exactly how many you may actually have the ability to buy. A few of these are the outcomes of your power consumption target calculations (just how much energy your family appliances and devices need so that you can function properly), the cost you may have at your disposal and the type of solar panel you might be using.
Also, depending on regardless if you are considering purchasing Solceller or you’re considering building your own panels yourself away from cheaper materials, the prices may vary. Therefore, the number of solar panels you can come up with in 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 amount of solar panels you will need, it is very important measure the amount of energy that a solar panel will offer, and compare it with all the value that you require. Due to the fact a typical household consumes about 8000 – 9000 kwh over a yearly basis, and the reality that a $300 solar panel of great quality can only provide about 100 – 200 watts of energy, the amount of panels you need to power your complete home may be quite substantial.
Needless to say, according to your needs, you might not always have to use up so much energy on a regular basis. Specifically if you are an environmental enthusiast, and you know how to choose appliances which provide better functionality, while consuming less energy, you may actually have the ability to reduce that number to half, as well as less.
Also, if you want to develop your own solar panel, you will probably 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 just need about 30 or 40 panels to supply enough power for your entire home.
This number can still be too big, but it can be reduced in order to use an additional type of energy, like wind power. This can offer 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.
Exercise caution, as various kinds of solar cells can provide a varying amount of energy. You are able to calculate the vitality output easily, however: once you build your DIY solar panel, measure the current and voltage it creates, and multiply them to get the watt value. Consequently, a little, 6 ampere solar panel which produces 12 volts, for instance, will offer you about 72 watts.
Now, this kind of weak solar panel may not provide you with excessive energy, but the good news is that we now have many inexpensive panels on the market that will offer two or more times just as much power, and also you don’t need to pay a lot more than 300 to 400 dollars for one. A solar array made from 10 to 20 of such panels would, therefore, represent a viable option in terms of 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 number of solar panels you will need. When it comes to panels using monocrystalline solar cells, as an example, the volume of sunlight needed for generating a specific quantity of energy is significantly less than with regards to thin film or polycrystalline cells.
In 2010, a business which produces good quality monocrystalline solar panels managed to break the entire world record for solar energy efficiency, producing solar cells that could transform greater than 24 % of the sun’s rays into usable electrical power.
Some researchers even take into account that, in a few years, it could be possible to create monocrystalline solar cells which will rise above the 30 % or maybe the 40 % mark, significantly improving the efficiency rating of these sorts of solar cells, and this of solar energy generally.
A good example of the energy efficiency that these particular solar panels will offer would be that a solar panel using a total of 36 monocrystalline cells can generally produce around 100 to 130 watts. This practically signifies that if you want 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 plan.
In comparison using these results, technologies using polycrystalline cells are barely able to find near 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 find such panels. It’s factual that you simply will not need as much panels to arrive at an over-all production of about 1 to 3 kw in this instance, but the problem is that the more 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 connection, polycrystalline cells are significantly better, since they are less weak as thin film-based technologies, and are somewhat more affordable than monocrystalline solar cells.
Budget Issues – Now, everyone is usually thinking about budget issues in terms of buying or manufacturing a solar panel. DIY solar panels are clearly cheaper, however, the quality differences could be great, not to mention that you will need to put plenty of work into it, if you wish your brand-new panels to do properly.
If you decide to buy a solar panel, on the other hand, you are going to curently have each of the numbers necessary regarding how many watts it creates, and just how stable it really is. By utilizing some simple math, you may then calculate exactly how many of these units you will need in order to meet your power target.
The key problem the following is there are many brands centering on offering various kinds of solar panels based on a huge number of different technologies. Because of this, you may have trouble choosing between them, and you should check around on numerous websites to learn what past buyers think about any particular product.
A lot of people would believe that about $3000 to $8000 could be enough for a viable solar panel array; however, the numbers might double depending on your requirements and the technology you want to use. Fortunately, most manufacturers happen to be starting to develop better technologies that enable people to buy more effective solar arrays with a considerably discounted price.
You need to take each of the options under consideration, however, and get away from clinging to some brands given that they possess a “catchier” marketing agenda. Ultimately, the numbers will reveal all you need to know, and you may oqepmz your own mind regarding which types of panels you should purchase, and what percentage of them you will want.
Summary – You will frequently realize that the business you work with might actually supply you with a viable plan in terms of working with energy consumption and solar panel numbers. Based upon your financial budget as well as the proficiency from the solar power array you need, they can often provide you with a precise estimate of how much energy you may get from your purchase.
Exercise caution, however, since various brands may sometimes develop new technologies that are cheaper and a lot more effective, and makes the designs of other companies seemingly obsolete. You could actually realize then that new opportunities can be shown at all the way.
So, should you be thoroughly informed concerning the factors that determine the caliber of the technology used for manufacturing panels, you will see that you happen to be in a significantly better position to build what percentage of them you require yourself, without having to concern yourself with any unknown factors.
