How to Work Out The Number Of Solar Panels You Require

If you are interested in the idea of using free, environmental friendly vitality to energy your household, and you want to have got a solar panel variety installed, probably the most basic requirements you have to keep track of is the number of solar panels that you need.

There are numerous factors that will determine how many you would need to use, and how several you will really be able to purchase. Some of these range from the results of your energy consumption focus on calculations (exactly how much energy your family gadgets and home appliances need in order to function appropriately), the budget you might have at your disposal and the type of solar cell you are using.

Also, based on whether you are considering the purchase of a higher-tech solar array or you're thinking of creating your own sections yourself from cheaper components, the prices can vary greatly. Therefore, the quantity of solar panels you can put together within an array can be different, and their quality may well also have to be assessed.

Calculating Energy Consumption

It is essential to measure the quantity of energy that a solar panel may offer, and compare it with the value that you want, if you want to decide precisely the amount of solar panels you will need. Considering that a typical household uses up about 8000 - 9000 kwh on the yearly schedule, and the truth that a $300 solar panel of good high quality can only offer about 100 - 200 watts of energy, the quantity of panels you should power your complete home could be quite substantial.

Of course, based on your needs, you might not always need to use up a lot energy frequently. Especially if you are an enviromentally friendly enthusiast, and you know how to pick appliances which provide better usefulness, while consuming less power, you might in fact be able to decrease that number to 50 %, or even less.

Also, if you want to build your personal solar panel, you will probably find that the producing costs can effectively be reduced to under $200 for any standard 36 cell solar power panel. Depending on the quality of your do-it-yourself solar array, you only will need about 30 or 40 panels to deliver enough power for your entire home.

It may be reduced if you would like use an additional type of electricity, such as breeze power, although this number can still be too large. This can give you more vitality on gloomy and wet days and nights, when solar panel systems don't function as well, minimizing the need for panels to 50 % or even much less.

Use caution, as different types of solar panels will provide a varying level of energy. You can calculate the electricity output quickly, however: once you build your Build-it-yourself solar panel, study the current and voltage it produces, and multiply them to have the watt value. A small, 6 ampere solar panel that creates 12 volts, for instance, will offer about 72 watts, consequently.

Now, this sort of weak solar power panel may not give you too much power, but fortunately that there are many inexpensive individual panels on the market that will offer a couple of times just as much power, and you don't need to pay more than 300 to 400 dollars for just one. A solar energy array manufactured from 10 to 20 of such panels would, therefore, represent a viable option when it comes to powering a large number of low energy appliances or gadgets.

Distinct Solar Panel Sorts

The efficiency and rate which solar cells can easily transform solar energy into electricity also plays a aspect in identifying how many solar energy panels you will need.

With regards to panels making use of monocrystalline solar cells, for example, the level of sunlight required for generating a specific amount of electricity is far less than in the case of slim film or polycrystalline cells.

In 2010, a company that produces premium quality monocrystalline solar energy panels was able to crack the world history for solar powered energy efficiency, making solar cells which could transform a lot more than 24 Per cent of the sun's rays into usable electrical power.

Some researchers even consider that, within a few years, it may be possible to create monocrystalline solar cells that are able to go beyond the 30 Per cent or even the 40 % tag, significantly enhancing the efficiency score of these kinds of solar cells, and this of solar technology in general.

An excellent example of the electricity efficiency that these solar panels can offer would be that a solar panel employing a total of 36 monocrystalline cells can generally generate around 100 to 130 watts. This practically ensures that if you want to get 1 kw (1000 watts), you will need about 10 of those panels. According to the brand name and quality of your panel, prices can range in between $3000 and $5000 just for this plan.

In contrast with these effects, technologies utilizing polycrystalline cellular material are hardly able to get near to the 20 Percent limit today, while thin film based technologies rarely provide about 15 to 17 % efficiency.

These numbers could conclude the technological superiority of monocrystalline PV cellular material, but they usually do not prove that the best selection is to buy this kind of panels. The problem is that the more monocrystalline solar panels you buy, the greater the cost difference becomes, even though it's true that you will not need as numerous panels to achieve a general output of about 1 to 3 kw in this instance.

You may also go for less vitality efficiency and a better prices option to avoid wasting money. In this regard, polycrystalline cells are far better, since they are not as weak as slim film-based technologies, and are considerably less expensive than monocrystalline solar cells.

Budget Problems

Now, many people are usually thinking about budget issues when it comes to acquiring or producing a solar power. DIY solar panel systems are obviously less costly, however, the high quality differences could be great, not forgetting that you will need to place a lot of work into it, if you would like your new sections to perform effectively.

If you decide to get a solar panel, alternatively, you will currently have all the numbers necessary concerning how many watts it produces, and exactly how stable it really is. By using some simple math, you can then estimate exactly how many of these devices you need in order to satisfy your energy focus on.

The main difficulty here is that you have many companies focusing on providing different types of solar panel systems based on a large number of different technologies. As a result, you could have a hard time picking between them, and you will have to look around on numerous websites to determine what past buyers consider any specific product.

Most people would believe that about $3000 to $8000 will be enough to get a viable solar power array; even so, the phone numbers might double depending on your requirements and the technologies you want to use. Fortunately, most manufacturers already are starting to create better technologies that allow customers to buy more potent solar arrays at a significantly lower price.

You will need to take every one of the options into account, however, and avoid clinging to many brands simply because they have a "catchier" marketing plan. Finally, the figures will show you everything you should know, and you may make up your own personal mind regarding which forms of panels you should purchase, and what number of them you will require.


You will often find that the business you do business with may actually supply you with a viable program when it comes to handling energy consumption and solar power panel numbers. According to your budget and also the proficiency of your solar power range you require, they could often provide you with a precise estimate of how much energy you will get from your obtain.

Use caution, nonetheless, since various brands may at times come up with new technologies that are cheaper and more effective, and would make the designs of other manufacturers seemingly out of date. You might actually realize then that new opportunities can appear at all the way.

So, if you are carefully informed about the factors that determine the quality of the technology used for developing panels, you will notice that you are in a much better situation to establish what percentage of them you will need yourself, without having to worry about any unknown variables.
