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, one of the most basic requirements you need to keep track of is the number of solar panels that you need.

There are many factors that would determine just how many you would need to use, and how many you will actually be able to buy. Some of these include the results of your energy consumption target calculations (how much energy your household appliances and devices need in order to function properly), the budget you have at your disposal and the type of solar panel you are using.

Also, depending on whether you are considering the purchase of a high-tech solar array or you're thinking of building your own panels yourself out of cheaper materials, the prices may vary. Therefore, the number of solar panels you can put together in an array may be different, and their quality might also have to be assessed.

Calculating Energy Consumption

If you want to determine precisely how many solar panels you need, it is essential to measure the amount 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 good quality can only provide about 100 - 200 watts of energy, the number of panels you need to power your entire home may be quite substantial.

Of course, depending on your needs, you might not always have to use up so much energy on a regular basis. Especially if you are an environmental enthusiast, and you know how to choose appliances that provide better functionality, while consuming less energy, you might actually be able to reduce that number to half, or even less.

Also, if you want to build your own solar panel, you might find that the manufacturing costs can effectively be reduced to under $200 for a standard 36 cell solar panel. Depending on the quality of your homemade solar array, you only need about 30 or 40 panels to provide enough power for your entire home.

This number may still be too large, but it can be reduced if you wish to use 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 as well, and reduce the need for panels to half or even less.

Use caution, as different types of solar cells will provide a varying amount of energy. You can calculate the energy output easily, however: after you build your DIY solar panel, measure the current and voltage it produces, and multiply them to obtain the watt value. As a result, a small, 6 ampere solar panel that produces 12 volts, for instance, will offer about 72 watts.

Now, such a weak solar panel may not provide you with too much energy, but the good news is that there are many inexpensive panels on the market that can offer two or more times as much power, and you don't have to pay more than 300 to 400 dollars for one. A solar array made of 10 to 20 of these 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 with which solar cells are able to transform solar energy into electricity also plays a part in determining how many solar panels you will need.

In the case of panels using monocrystalline solar cells, for example, the amount of sunlight needed for generating a specific amount of energy is far less than in the case of thin film or polycrystalline cells.

In 2010, a company that produces high quality monocrystalline solar panels was able to break the world record for solar energy efficiency, producing solar cells that could transform more than 24 % of the sun's rays into usable electrical power.

Some researchers even consider that, in a few years, it may be possible to create monocrystalline solar cells that are able to go beyond the 30 % or even the 40 % mark, significantly increasing the efficiency rating of these types of solar cells, and that of solar energy in general.

A good example of the energy efficiency that these solar panels can offer would be that 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 need about 10 of these panels. Depending on the quality and brand of the panel, pricing can range between $3000 and $5000 for this plan.

In contrast with these results, technologies using polycrystalline cells are barely able to get 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, but they do not prove that the best decision is to buy 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 buy, the greater the price difference becomes.

You may also opt for less energy efficiency and a better pricing option in order to save money. In 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.

Budget Issues

Now, everyone is usually thinking about budget issues when it comes to buying or manufacturing a solar panel. DIY solar panels are obviously cheaper, however, the quality differences can be great, not to mention that you will need to put a lot of work into it, if you want your new panels to perform properly.

If you decide to buy a solar panel, on the other hand, you will already have all the numbers necessary regarding how many watts it produces, and how stable it is. By using some simple math, you can then calculate exactly how many of these devices you need in order to meet your energy target.

The main problem here is that there are many brands focusing on offering different types of solar panels based on a large number of different technologies. As a result, you may have a hard time choosing between them, and you will have to look around on numerous websites to find out what past buyers think about any particular product.

Most people would believe that about $3000 to $8000 would be enough for a viable solar panel array; however, the numbers might double depending on your needs and the technology you want to use. Fortunately, most manufacturers are already starting to develop better technologies that allow people to buy more efficient solar arrays at a considerably lower price.

You have to take all the options into account, however, and avoid clinging to some brands simply because they have a "catchier" marketing agenda. Ultimately, the numbers will show you everything you need to know, and you can make up your own mind regarding which types of panels you should buy, and how many of them you will need.

Summary

You will often find that the company you do business with may actually provide you with a viable plan when it comes to dealing with energy consumption and solar panel numbers. Based on your budget and the proficiency of the solar power array you require, they can often give you a precise estimate of how much energy you can get from your purchase.

Use caution, however, since various brands may at times come up with new technologies that are cheaper and more effective, and would make the designs of other companies seemingly obsolete. You might actually realize then that new opportunities can appear at every step of the way.

So, if you are thoroughly informed about the factors that determine the quality of the technology used for manufacturing panels, you will find that you are in a much better position to establish how many of them you need yourself, without having to worry about any unknown factors.

The sun is the primary source of energy on Earth and sunlight can be converted directly into electricity using solar panels. Electricity has become indispensable in life. It powers the machines that most us use daily. What if you can create your own solar panel? In this article, we will show you a straightforward method of building your own functional solar panel. THE COMPONENTS A solar panel is usually manufactured from six (6) components namely the PV (photovoltaic) cell or solar cell which generates the electricity, the glass which covers and protects the solar cells, the frame which provides rigidity, the backsheet where the solar cells are laid, the junction box where the wirings are enclosed and connected, and the encapsulant which serves as adhesives. Since most people does not have access to equipment in manufacturing solar panels, it is important to note and understand those six components in order for anyone to be able to plan the materials needed to create a do-it-yourself or home-made solar panel.

Life is a process that happens over TIME and a culmination of various SEASONS that an individual goes through. Your life is the sum total of the seasons you experienced as you lived it. There are good, exciting, memorable seasons and there are the mild, cold, dark and painful seasons you just want to forget about. In our daily interactions with one another, we need to be SENSITIVE enough about where others are at. The moment we are selfish to ignore other people's moments and seasons we will find ourselves not able to interact with others effectively as our TIMING and RELEVANCE will like sour grapes in the mouth of those we are talking to. Successful people are sensitive enough to comprehend where others are at and speak accordingly. Watch out that your very GOOD INTENTIONS executed within a wrong TIME FRAME may produce DISASTROUS after effects. Be watchful about statements you may pour out without thinking and being sensitive to situations which could create more harm than good. Seasons of dryness and wilderness are inevitable in life. It is your reaction towards the season that will make or break you. The wilderness experience is not a death sentence but is meant to be the college where you will come out better on character and attitude and ready for greatness. Momentary pain and discomfort will surely pass. Hang on to the dreams and visions you have. There are times in my own life when I have experience lack. While I was doing every correct thing in terms of managing finances, managing people, taking care of the poor and feeding the hungry, I still faced lack one way or the other. My attitude was never to stop doing the right thing. I was tempted to ask why such bad could happen to me. I suddenly realized that life is full of seasons. I could have chosen to remain stressed all my life or square my shoulders and keep trusting that all would be well someday. In these seasons you need family and friends that can stand by you. You can never say I am the master at all seasons. The attitude is to say I am willing to learn all there is as long as it makes me a better not bitter person. Different seasons and situations require different approaches and etiquette and conduct. Eladrin 5e

A solar panel is a device that is used to absorb energy from the sun in order to generate heat or in many cases electricity. It is also referred to as a photovoltaic cell since it is made of many cells that are used to convert the light from the sun into electricity. The only raw material for these solar panels is the sun. it is made in such a way that the cells face the sun in order to enable maximum absorption of the sun rays. The greater the energy from the sun is, the more the electricity that is generated. Solar panels are used in many homesteads in the world due to their many pros that are far more than cons. Some of these pros are discussed below. cleaning solar panels
