If you are considering the thought of using free, environmental friendly energy to power your household, and you need to have a solar panel array installed, just about the most basic requirements you have to monitor is the number of solar panels that you require.
There are many factors that could determine how many you would need to use, and how many you will actually have the ability to buy. A few of these are the outcomes of your energy consumption target calculations (exactly how much energy your household appliances and devices need so that you can function properly), the budget you may have available and the kind of solar panel you happen to be using.
Also, based on whether you are considering the purchase of Solceller or you’re thinking about building your personal panels yourself away from cheaper materials, the prices may vary. Therefore, the quantity of solar panels it is possible to put together within an array may be different, along with their quality might also need to be assessed.
Calculating Energy Consumption – If you want to determine precisely how many solar panels you will need, it is important to measure the volume of energy that a solar panel can offer, and compare it with the value that you require. Considering that a normal household consumes about 8000 – 9000 kwh on a 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 quantity of panels you need to power your complete home could be quite substantial.
Obviously, based on your requirements, you possibly will not always need to use up a great deal energy frequently. Specifically if you are an environmental enthusiast, and you know how to pick appliances which provide better functionality, while consuming less energy, you could actually be able to reduce that number to half, or even less.
Also, if you wish to construct your own solar panel, you can definitely find that this manufacturing costs can effectively be reduced to under $200 to get a standard 36 cell solar panel. Depending on the quality of your homemade solar array, you just need about 30 or 40 panels to provide enough power for your entire home.
This number may still be too large, but it could be reduced if you wish to work with an additional form of energy, such as wind power. This may provide you with more energy on cloudy and rainy days, when solar panels don’t operate too, and lower the necessity for panels to half or even less.
Exercise caution, as different types of solar cells can provide a varying amount of energy. You can calculate the power output easily, however: when you develop your DIY solar panel, look at the current and voltage it generates, and multiply them to obtain the watt value. Consequently, a small, 6 ampere solar panel that produces 12 volts, for example, will offer about 72 watts.
Now, such a weak solar panel may well not offer you excessive energy, but the good thing is there are many inexpensive panels on the market that will offer 2 or more times just as much power, and you also don’t must pay more than 300 to 400 dollars for starters. A solar array made from 10 to 20 of these panels would, therefore, represent a viable option in terms of powering a huge number of low energy appliances or gadgets.
Different Solar Panel Types.
The pace and efficiency in which solar cells are able to transform solar energy into electricity also plays a part in determining the number of solar panels you will want. When it comes to panels using monocrystalline solar cells, as an example, the amount of sunlight necessary for creating a specific quantity of energy is far lower than when it comes to thin film or polycrystalline cells.
In 2010, an organization which produces good quality monocrystalline solar panels was able to break the planet record for solar energy efficiency, producing solar cells that may transform greater than 24 % of the sun’s rays into usable electrical power.
Some researchers even take into account that, in a several years, it may be possible to create monocrystalline solar cells that are able to go beyond the 30 % or even the 40 % mark, significantly improving the efficiency rating of these sorts of solar cells, and that of solar energy generally speaking.
A good demonstration of the power efficiency that these 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 means that if you wish to get 1 kw (1000 watts), you will require about 10 of such panels. Depending on the quality and type of the panel, pricing can vary between $3000 and $5000 for this particular plan.
In comparison using these results, technologies using polycrystalline cells are barely able to get 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, but they do not prove the best decision is to find such panels. It’s true that you will not need as many panels to reach a general output of about 1 to 3 kw in this case, but the problem is that the more monocrystalline solar panels you purchase, the higher the price difference becomes.
You may even go for less energy efficiency as well as a better pricing option to avoid wasting money. In connection with this, polycrystalline cells are far better, as they are not as weak as thin film-based technologies, and are somewhat less expensive than monocrystalline solar cells.
Budget Issues – Now, everybody is usually thinking of budget issues with regards to buying or manufacturing a solar panel. DIY solar panels are clearly cheaper, however, the product quality differences could be great, not to mention that you will need to put a lot of work in it, if you want your brand-new panels to do properly.
If you decide to purchase a solar panel, on the contrary, you are going to curently have all of the numbers necessary regarding the number of watts it produces, and how stable it really is. By making use of some simple math, you may then calculate exactly what percentage of these devices you require to be able to meet your energy target.
The key problem the following is that we now have many brands centering on offering various kinds of solar panels based on a large number of different technologies. Consequently, you may have a hard time choosing between the two, and you will need to browse around on numerous websites to discover what past buyers take into consideration any particular product.
Most people would think that about $3000 to $8000 would be enough for any viable solar panel array; however, the numbers might double according to your requirements and the technology you would like to use. Fortunately, most manufacturers already are starting to develop better technologies that enable people to buy better solar arrays with a considerably discounted price.
You need to take each of the options into consideration, however, and get away from clinging to a few brands given that they have a “catchier” marketing agenda. Ultimately, the numbers will show you all you need to know, and you could oqepmz up your own mind regarding which varieties of panels you should get, and what number of them you will require.
Summary – You will often discover that the business you work with might actually provide you with a viable plan with regards to dealing with energy consumption and solar panel numbers. Based upon your financial budget as well as the proficiency of the solar power array you want, they can often give you a precise estimate of methods much energy you may get from your purchase.
Use caution, however, since various brands may sometimes think of technologies which are cheaper and a lot more effective, and makes the designs of other companies seemingly obsolete. You may actually realize then that new opportunities can appear at all the way.
So, should you be thoroughly informed concerning the factors that determine the quality of the technology utilized for manufacturing panels, you will find that you happen to be in a far better position to build how many of them you require yourself, without having to be worried about any unknown factors.
