For those who are serious about the idea of using free, environmental friendly energy to power your household, and you choose to possess a solar panel array installed, one of your most standard requirements you’ll need to help keep track of will be the number of solar panels which you need to have. Get a lot more details about Paneles solares colombia
There are actually lots of aspects that would establish just how lots of you’d must use, and how quite a few you may truly be capable of acquire. A few of these involve the results of one’s energy consumption target calculations (how much energy your household appliances and devices want in order to function properly), the spending budget you have got at your disposal and the kind of solar panel that you are using.
Also, according to regardless of whether you might be thinking of the obtain of a high-tech solar array or you are pondering of creating your own personal panels yourself out of more affordable supplies, the costs may well vary. Consequently, the number of solar panels you are able to put with each other in an array may be different, and their high quality may also must be assessed.
Calculating Energy Consumption
If you need to establish precisely how many solar panels you may need, it can be important to measure the quantity of energy that a solar panel can give, and evaluate it with all the value that you require. Contemplating that a normal household consumes about 8000 – 9000 kwh on a yearly basis, along with the truth that a $300 solar panel of very good top quality can only offer about 100 – 200 watts of energy, the number of panels you’ll need to power your entire home may be pretty substantial.
Of course, depending on your requirements, you may not usually have to use up so much energy on a regular basis. Especially when you are an environmental enthusiast, and also you know how to decide on appliances that give better functionality, although consuming significantly less energy, you could basically be able to decrease that number to half, or even much less.
Also, if you want to build your own personal solar panel, you could find that the manufacturing costs can correctly be reduced to beneath $200 for a typical 36 cell solar panel. Based on the quality of one’s homemade solar array, you only require about 30 or 40 panels to provide sufficient power for your entire home.
This number might nevertheless be also substantial, nevertheless it might be decreased when you wish to utilize an more sort of energy, for example wind power. This could provide you more energy on cloudy and rainy days, when solar panels do not operate at the same time, and decrease the want for panels to half or perhaps significantly less.
Use caution, as various sorts of solar cells will give a varying quantity of energy. You’ll be able to calculate the energy output effortlessly, on the other hand: right after you build your DIY solar panel, measure the current and voltage it produces, and multiply them to get the watt worth. Consequently, a modest, 6 ampere solar panel that produces 12 volts, for example, will supply about 72 watts.
Now, such a weak solar panel might not provide you with too considerably energy, however the great news is that there are actually quite a few economical panels available that will supply two or much more times as significantly power, and you don’t must spend more than 300 to 400 dollars for one. A solar array made of 10 to 20 of those panels would, consequently, represent a viable option in regards to powering a big number of low energy appliances or gadgets.
Unique Solar Panel Varieties
The price and efficiency with which solar cells are in a position to transform solar energy into electricity also plays a part in determining how several solar panels you will need.
In the case of panels using monocrystalline solar cells, one example is, the level of sunlight needed for creating a certain amount of energy is far less than inside the case of thin film or polycrystalline cells.
In 2010, a company that produces good quality monocrystalline solar panels was in a position to break the world record for solar energy efficiency, generating solar cells that could transform additional than 24 % on the sun’s rays into usable electrical power.
Some researchers even take into consideration that, in a couple of years, it may be feasible to make monocrystalline solar cells which can be in a position to go beyond the 30 % and even the 40 % mark, drastically growing the efficiency rating of these kinds of solar cells, and that of solar energy in general.
A good instance with the energy efficiency that these solar panels can supply will be that a solar panel using a total of 36 monocrystalline cells can generally create around one hundred to 130 watts. This practically means that if you want to have 1 kw (1000 watts), you will need about 10 of these panels. Based on the top quality and brand with the panel, pricing can range amongst $3000 and $5000 for this strategy.
In contrast with these results, technologies using polycrystalline cells are barely able to obtain close towards the 20 % limit nowadays, when thin film based technologies hardly provide about 15 to 17 % efficiency.
These numbers might conclude the technological superiority of monocrystalline PV cells, but they usually do not prove that the very best decision is to get such panels. It’s true which you is not going to want as lots of panels to reach a basic output of about 1 to 3 kw within this case, but the dilemma is that the far more monocrystalline solar panels you acquire, the greater the price difference becomes.
You could also choose much less energy efficiency as well as a better pricing option in an effort to save money. Within this regard, 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.
Now, everybody is normally thinking about price range concerns in regards to getting or manufacturing a solar panel. DIY solar panels are naturally more affordable, nonetheless, the high-quality variations is usually great, not to mention which you will really need to put loads of work into it, if you need your new panels to execute adequately.
Should you make a decision to purchase a solar panel, on the other hand, you can currently have all of the numbers important with regards to how quite a few watts it produces, and how stable it can be. By using some very simple math, you’ll be able to then calculate exactly how many of these devices you may need so that you can meet your energy target.
The principle dilemma right here is that you can find lots of brands focusing on supplying different kinds of solar panels determined by a sizable number of different technologies. Consequently, you could possibly have a difficult time deciding on amongst them, and you’ll need to look around on various websites to find out what past buyers consider about any particular product.
Most people would think that about $3000 to $8000 will be enough for a viable solar panel array; nonetheless, the numbers may possibly double depending on your desires along with the technology you need to use. Thankfully, most producers are already beginning to create improved technologies that enable people to purchase far more effective solar arrays at a significantly decrease value.
You have got to take each of the options into account, nevertheless, and steer clear of clinging to some brands simply simply because they have a “catchier” marketing agenda. In the end, the numbers will show you all the things you need to understand, and also you can make up your personal mind with regards to which types of panels you’ll want to acquire, and how a lot of of them you will need.
