If you are considering the thought of using free, environmental friendly energy to power your household, and you want to have a solar panel array installed, probably the most simple requirements you need to keep an eye on is the number of solar panels you need.
There are many factors that could determine just how many you would need to use, and just how many you are going to actually have the ability to buy. A few of these include the outcomes of your power consumption target calculations (exactly how much energy your family appliances and devices need so that you can function properly), the cost you may have readily available and the kind of solar panel you happen to be using.
Also, depending on regardless if you are considering the purchase of Solceller or you’re thinking of building your own panels yourself from cheaper materials, the prices can vary greatly. Therefore, the number of solar panels you can put together inside an array might be different, and their quality might also have to be assessed.
Calculating Energy Consumption – If you wish to determine precisely the number of solar panels you will need, it is very important measure the volume of energy a solar panel will offer, and compare it using the value that you want. Due to the fact an ordinary household consumes about 8000 – 9000 kwh on the yearly basis, and the truth that a $300 solar panel of good quality can only provide about 100 – 200 watts of energy, the amount of panels you have to power your complete home could be quite substantial.
Obviously, according to your needs, you possibly will not always need to use up a great deal energy on a regular basis. Specifically if you are an environmental enthusiast, and you know how to select appliances which provide better functionality, while consuming less energy, you may actually have the capacity to reduce that number to half, as well as less.
Also, if you want to construct your own solar panel, you might 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 just need about 30 or 40 panels to provide enough power for the entire home.
This number might still be too big, but it could be reduced if you would like use an additional type of energy, like wind power. This can provide you with more energy on cloudy and rainy days, when solar panels don’t operate as well, and reduce the need for panels to half or perhaps less.
Be cautious, as different types of solar cells can provide a varying level of energy. It is possible to calculate the vitality output easily, however: after you develop your DIY solar panel, measure the current and voltage it generates, and multiply them to get the watt value. Consequently, a little, 6 ampere solar panel that produces 12 volts, for instance, will offer about 72 watts.
Now, this type of weak solar panel may well not present you with excessive energy, but the good thing is that there are many inexpensive panels on the market that will offer 2 or more times just as much power, and you also don’t have to pay greater than 300 to 400 dollars for starters. A solar array made from 10 to 20 of such panels would, therefore, represent a viable option when it comes to powering a lot of low energy appliances or gadgets.
Different Solar Panel Types.
The speed and efficiency with which solar cells have the ability to transform solar energy into electricity also plays a part in determining how many solar panels you will need. With regards to panels using monocrystalline solar cells, for example, the quantity of sunlight required for creating a specific amount of energy is significantly lower than in the case of thin film or polycrystalline cells.
In 2010, a business that produces top quality monocrystalline solar panels was able to break the world record for solar energy efficiency, producing solar cells that could transform a lot more than 24 % in the sun’s rays into usable electrical power.
Some researchers even take into account that, in a couple of years, it could be easy to create monocrystalline solar cells that are able to exceed the 30 % or maybe the 40 % mark, significantly improving the efficiency rating of these types of solar cells, and that of solar energy in general.
A great example of the energy efficiency that these particular solar panels will offer is a solar panel utilizing a total of 36 monocrystalline cells can generally produce around 100 to 130 watts. This practically implies 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 can range between $3000 and $5000 for this plan.
In contrast with these results, technologies using polycrystalline cells are barely capable of getting 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, nevertheless they usually do not prove that the best decision is to purchase such panels. It’s true 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 however , the more monocrystalline solar panels you purchase, the higher the price difference becomes.
You may also choose less energy efficiency as well as a better pricing option to avoid wasting money. In this connection, polycrystalline cells are significantly better, since they are not as weak as thin film-based technologies, and are somewhat more affordable than monocrystalline solar cells.
Budget Issues – Now, everyone is usually considering budget issues with regards to buying or manufacturing a solar panel. DIY solar panels are obviously cheaper, however, the product quality differences may be great, not to mention that you will need to put lots of work in it, if you wish your brand new panels to execute properly.
If you choose to get a solar panel, on the other hand, you will already have each of the numbers necessary regarding how many watts it produces, and how stable it is actually. By making use of some simple math, you can then calculate exactly what number of these products you require so that you can meet your energy target.
The primary problem here is that we now have many brands focusing on offering different types of solar panels based upon a large number of different technologies. Consequently, you could have trouble choosing between the two, and you will need to check around on numerous websites to find out what past buyers take into consideration any particular product.
Many people would feel that about $3000 to $8000 could be enough for any viable solar panel array; however, the numbers might double according to your requirements and the technology you need to use. Fortunately, most manufacturers are already beginning to develop better technologies that permit people to buy more effective solar arrays in a considerably discounted price.
You have to take each of the options into account, however, and steer clear of clinging to a few brands simply because they possess a “catchier” marketing agenda. Ultimately, the numbers will reveal all you need to know, and you could oqepmz up your own mind regarding which types of panels you should purchase, and what percentage of them you will want.
Summary – You will sometimes discover that the business you work with may actually offer you a viable plan with regards to dealing with energy consumption and solar panel numbers. Based upon your financial budget and the proficiency from the solar power array you need, they could often give you a precise estimate of how much energy you will get from your purchase.
Be cautious, however, since various brands may at times think of technologies which are cheaper and more effective, and would make the designs of other companies seemingly obsolete. You might actually realize then that new opportunities can be shown at all the way.
So, if you are thoroughly informed regarding the factors that determine the quality of the technology utilized for manufacturing panels, you will notice that you might be in a far better position to build what number of them you need yourself, without having to concern yourself with any unknown factors.
