How you can Work Out How Many Solar Panels You may need


If you are interested in the idea of applying free, environmentally friendly electricity to power your family, and you want to have a solar power array installed, one of the most standard requirements you need to keep track of could be the number of solar panels that you need.

There are several factors that would determine how many you would need to employ, and how many you will be able to buy. Some of these add the results of your energy consumption targeted calculations (how much electricity your household appliances along with devices need in order to purpose properly), the budget you have you can use, and the type of solar panel you will be using.

Also, depending on whether or not considering the purchase of a high-tech solar array or you aren’t thinking of building your own energy yourself out of cheaper elements, the prices may vary. Therefore, the volume of solar panels you can put together in the array may be different, and the quality might also have to be evaluated.

Calculating Energy Consumption

If you wish to determine precisely how many solar power panels you need, it is essential to measure the quantity of energy that a solar panel can provide, and compare it using the value that you require. Considering that an ordinary household consumes about 8000 – 9000 kwh on the yearly basis, and the undeniable fact that a $300 solar panel of great quality can only provide 100 – 200 w of energy, the number of panels you have to power your entire home might be quite substantial.

Of course, based on your needs, you might not always have to make use of up so much energy regularly. Especially if you are an environmental fanatic, and you know how to choose home appliances that provide better functionality, whilst consuming less energy, you may actually be able to reduce which number to half, or even less.

Also, if you want to create your own solar panel, you might find that these manufacturing costs can efficiently be reduced to below $200 for a standard thirty-six cell solar panel. Depending on the high quality of your homemade solar variety, you only need about thirty or 40 panels to supply enough power for your whole home.

This number might still be too large, but it could be reduced if you wish to use an extra type of energy, such as blowing wind power. This can offer you much more energy on cloudy along with rainy days when solar panel systems don’t operate as well and lessen the need for panels to fifty percent or even less.

Use caution, while different types of solar cells will provide some sort of varying amounts of energy. It is possible to calculate the energy output effortlessly, however: after you build you DO IT YOURSELF solar panel, measure the current and also voltage it produces, and also multiply them to obtain the watts value. As a result, a small, 6th-ampere solar panel that creates 12 volts, for instance, will offer you about 72 watts.

Today, such a weak solar panel may well not provide you with too much energy, nevertheless, the good news is that there are many low-cost panels on the market that can offer you two or more times as much strength, and you don’t have to pay more as compared to 300 to 400 us dollars for one. A solar range made of 10 to 20 such panels would, therefore, stand as a viable option when it comes to energizing a large number of low-energy devices or gadgets.

Different Solar power electrical Types

The rate and performance with which solar cells are able to convert solar energy into electricity furthermore play a part in determining how many solar energy panels you will need.

In the case of panels making use of monocrystalline solar cells, for example, the volume of sunlight needed for generating a certain amount of energy is far less compared to the case of a thin motion picture or polycrystalline cells.

Completely, a company that produces good quality monocrystalline solar panels was able to split the world record for solar-powered energy efficiency, producing solar cells that may transform more than 24 percent of the sun’s rays into useful electrical power.

Some researchers perhaps consider that, in a few years, it usually is possible to create monocrystalline photovoltaic cells that are able to go beyond the thirty percent or even the 40 % symbol, significantly increasing the proficiency rating of these types of photovoltaic cells, and that of solar energy normally.

A good example of the energy efficiency the solar panels can offer would be that your solar panel using a total connected with 36 monocrystalline cells can certainly generally produce around 75 to 130 watts. That practically means that if you want to find 1 kW (1000 watts), you will need about 10 of these panels. Depending on the quality in addition to the brand of the panel, rates can range between $3000 in addition to $5000 for this plan.

Compared with these results, technologies employing polycrystalline cells are seldom able to get close to the 20 percent limit today, while tiny film-based technologies almost never provide about 15 to help 17 % efficiency.

These kinds of numbers may conclude often the technological superiority of monocrystalline PV cells, but they will not prove that the best decision is always to buy such panels. Is actually true that you will not need as many panels to reach a general result of about 1 to 3 kW in this case, but the problem is the more monocrystalline solar panels you get, the greater the price difference will become.

You may also opt for less vitality efficiency and a better cost option in order to save money. Regarding this, polycrystalline cells are more effective, as they are not as weak as thin film-based technologies, and therefore are somewhat less expensive than monocrystalline solar cells.

Budget Issues

Today, everyone is usually thinking about price range issues when it comes to buying or perhaps manufacturing a solar panel. DO IT YOURSELF solar panels are obviously less costly, however, the quality differences may be great, not to mention that you will need to set a lot of work into it if you need your new panels to perform effectively.

If you decide to buy a solar panel, alternatively, you will already have all the amounts necessary regarding how many w it produces, and how secure it is. By using some basic math, you can then calculate precisely how many of these devices you need so that you can meet your energy target.

The key problem here is that there are quite a few brands focusing on offering different kinds of solar panels based on a large number of several technologies. As a result, you may have a very really hard time deciding between them, and you will have to go searching on numerous websites to uncover what past buyers look at any particular product.

The majority of people would believe that about $3000 to $8000 would be ample for a viable solar panel number; however, the numbers could double depending on your needs along with the technology you want to use. The good thing is, that most manufacturers are already noticed that you develop better technologies this allows people to buy more cost-effective solar arrays at a drastically lower price.

You have to take every one of the options into account, however, avoid clinging to some brands simply because have a “catchier” marketing intention. Ultimately, the numbers will disclose everything you need to know, and you can make up your own mind regarding which will type of panels you should buy, and exactly how many of them you will need.


You might often find that the company you choose to do business with may actually give you a viable plan when it comes to handling energy consumption and cell numbers. Based on your budget along with the proficiency of the solar power range you require, they can often offer you a precise estimate of how significantly energy you can get from your obtain.

Use caution, however, since different brands may at times formulate new technologies that are less costly and more effective, and tends to make the designs of other companies relatively obsolete. You might actually recognize then that new options can appear at every step of the approach.

So, if you are thoroughly knowledgeable about the factors that decide the quality of the technology useful for manufacturing panels, you will find you are in a much better position to ascertain how many of them you need yourself, without having to worry about any unidentified factors.
