If you are interested in the idea of using free, environmental friendly energy to power your household, and you want to have a solar panel array installed, probably the most basic requirements you should keep track of is the number of solar panels you need.
There are numerous factors that would determine just how many you should use, and how many you will actually have the capacity to buy. Some of these range from the results of your power consumption target calculations (exactly how much energy your family appliances and devices need to be able to function properly), your budget you may have available and the type of solar panel you might be using.
Also, according to if you are considering the purchase of Solceller or you’re considering building your own panels yourself from cheaper materials, the values can vary greatly. Therefore, the number of solar panels it is possible to put together within an array might be different, and their quality might must also be assessed.
Calculating Energy Consumption – If you wish to determine precisely the number of solar panels you need, it is essential to measure the volume of energy that a solar panel will offer, and compare it with the value that you want. Given that a typical household consumes about 8000 – 9000 kwh on a yearly basis, and the truth that a $300 solar panel of good quality can only provide about 100 – 200 watts of energy, the quantity of panels you need to power your entire home may be quite substantial.
Needless to say, based on your preferences, you possibly will not always have to use up a lot energy regularly. Particularly if you are an environmental enthusiast, and you understand how to choose appliances which provide better functionality, while consuming less energy, you may actually have the capacity to reduce that number to half, or even less.
Also, if you wish to build your own solar panel, you can definitely find the 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 simply need about 30 or 40 panels to offer enough power to your entire home.
This number might still be too big, but it can be reduced in order to work with an additional type of energy, such as wind power. This can offer you more energy on cloudy and rainy days, when solar panels don’t operate also, and minimize the requirement for panels to half or even less.
Exercise caution, as various kinds of solar cells can provide a varying quantity of energy. It is possible to 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 have the watt value. Consequently, a small, 6 ampere solar panel that creates 12 volts, as an example, will offer you about 72 watts.
Now, this kind of weak solar panel might not provide you with excessive energy, but the good thing is that there are many inexpensive panels on the market that can offer several times just as much power, and you don’t must pay more than 300 to 400 dollars for one. A solar array made from 10 to 20 of those panels would, therefore, represent a viable option when it comes to powering a large number of low energy appliances or gadgets.
Different Solar Panel Types.
The rate and efficiency in which solar cells can transform solar energy into electricity also plays a part in determining the amount of solar panels you will require. When it comes to panels using monocrystalline solar cells, for instance, the amount of sunlight needed for establishing a specific quantity of energy is way lower than in the case of thin film or polycrystalline cells.
In 2010, a company that produces high quality monocrystalline solar panels could break the planet record for solar energy efficiency, producing solar cells that may transform greater than 24 % in the sun’s rays into usable electrical power.
Some researchers even take into account that, in a couple of years, it may be easy to create monocrystalline solar cells that are able to rise above the 30 % or even the 40 % mark, significantly increasing the efficiency rating of these sorts of solar cells, and this of solar energy generally speaking.
An excellent illustration of the energy efficiency that these solar panels can provide is a solar panel using a total of 36 monocrystalline cells can generally produce around 100 to 130 watts. This practically means that if you want to get 1 kw (1000 watts), you will want 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 comparison with 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, nevertheless they tend not to prove that this best decision is to buy such panels. It’s factual that you simply will not need as much panels to achieve a broad output of about 1 to 3 kw in this instance, but however , the greater monocrystalline solar panels you buy, the greater the price difference becomes.
You might also choose less energy efficiency as well as a better pricing option in order to save money. In connection with this, polycrystalline cells are significantly better, as they are not as weak as thin film-based technologies, and they are somewhat cheaper than monocrystalline solar cells.
Budget Issues – Now, everybody is usually thinking about budget issues with regards to buying or manufacturing a solar panel. DIY solar panels are obviously cheaper, however, the product quality differences could be great, not to mention that you will want to put lots of work in it, if you want your brand new panels to perform properly.
If you opt to purchase a solar panel, on the contrary, you may have each of the numbers necessary regarding how many watts it generates, and how stable it is actually. By making use of some simple math, after that you can calculate exactly what number of these devices you will need so that you can meet your power target.
The main problem is that there are many brands centering on offering several types of solar panels based upon a large number of different technologies. Consequently, you could have trouble choosing between them, and you should browse around on numerous websites to find out what past buyers take into consideration any particular product.
Most people would feel that about $3000 to $8000 could be enough for a viable solar panel array; however, the numbers might double according to your requirements and the technology you need to use. Fortunately, most manufacturers already are beginning to develop better technologies that enable men and women to buy more effective solar arrays in a considerably discounted price.
You have to take all of the options under consideration, however, and avoid clinging to a few brands since they have a “catchier” marketing agenda. Ultimately, the numbers will reveal all that you should know, and you could oqepmz your own mind regarding which kinds of panels you should buy, and what percentage of them you will need.
Summary – You will often find that the business you do business with may actually supply you with a viable plan in terms of coping with energy consumption and solar panel numbers. According to your finances and also the proficiency of 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.
Use caution, however, since various brands may occasionally think of new technologies that are cheaper and more effective, and makes the types of other businesses seemingly obsolete. You may actually realize then that new opportunities can appear at all the way.
So, should you be thoroughly informed about the factors that determine the quality of the technology used for manufacturing panels, you will notice that you are in a significantly better position to determine how many of them you require yourself, without needing to concern yourself with any unknown factors.
