How to Work Out How Many Solar Panels You Need

If you are interested in the idea of using free, environmental friendly energy to power your household, and you want to have a System 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 System 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 System 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 System 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 System Solar Panel, you might find that the manufacturing costs can effectively be reduced to under $200 for a standard 36 cell System 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 System Solar Panel, measure the current and voltage it produces, and multiply them to obtain the watt value. As a result, a small, 6 ampere System Solar Panel that produces 12 volts, for instance, will offer about 72 watts.

Now, such a weak System 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 System 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 System 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 System 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 System 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 System 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 System 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.

Advantages of Solar Panels

A System 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.

One very important advantage of using solar panels is that they do not emit any gases that are common in green houses. The panels do not emit any smoke, chemical or heavy metals that can be risk factors to human health. Solar panels are therefore environmental friendly when compared to burning of fossil fuels to generate energy. This is very important since carbon emissions are dangerous and avoiding their emission helps in safeguarding our present and future environment. Being environment friendly is important since the government is constantly coming up with ways to control global warming and the use of solar panels is a great way to start. The solar panels therefore maintain a clean setting and they leave the air fresh. More importantly they help in prevention of many cancer incidences. This is because some products from some sources of energy like nuclear energy have been said to cause cancer due to initiation of mutations in cells.

Secondly, use of solar panels ensures ongoing free energy for those who use it. This is mainly because the only cost incurred is that of installation. Once the installation has been done the energy is free since the panel does not require regular maintenance or fuel to run it. It also requires no raw materials for its operation. It works as long as there are sun rays which is an everyday thing in most parts of the world. In a world where equal distribution of resources is continuously being sought, this is very important since each and everyone has equal rights when it comes to use of solar energy. This is because the energy from the sun falls on all. This is a good way to maintain equality as compared with energy from fossil fuel which low income homesteads do not afford in many cases.

There is also the advantage in that, the use of solar panels enable the decentralization of power. This is very important since it is very cheap. This is mainly because when power is not decentralized, it has to be shared by all and is as a result transported to many areas. With this happening, there are very many costs that are incurred. These include; the wear and tear of vehicles, the air pollution among others. These costs are all incorporated in the electricity bills of individuals as the government does not cover the expenses. It is therefore more advantageous to use solar panels as a saving plan and to create a sense of fairness since those in power tend to take advantage and use their positions to embezzle funds. This is not fair on the citizens’ part. This is because most of them struggle to make ends meet.

A System Solar Panel can be operated off grid. This is a great advantage for those who live in very isolated areas or in rural regions. Off grid means that the house is not connected to the state’s electricity grid. This has the advantage of low cost since installation may be very expensive for those living in isolated areas. These individuals have their power lines disconnected in many instances due to the fact that it is sometimes less affordable for many. Solar panels offer a solution for this since they do not require as much to be installed. However, those living in towns can also use the off-grid technique. An added advantage in this is that there are no rules governing whether or not one wants to operate off- grid or on-grid when it comes to use of solar panels. This however is an issue when using fossil fuel generated electricity.

Solar panels generate job opportunities. This is of great importance since there is a very high rate of unemployment in the world today. These jobs are come about in the form of, manufacturing of the solar panels, research about further improvements, maintenance, development and cultural integration. With the continued presence of the sun, these jobs are guaranteed since there is ongoing improvements and modification of this device. Jobs like maintenance and installation do not require a long-term training and are therefore more advantageous for those who do not have many skills and are unemployed.

Use of solar energy is safe from price manipulations and politics. The fact that there are no raw materials that are solely controlled by monopolies ensures that there is no manipulation of prices as is the case with fossil fuels. With fossil fuels, the prices can rise as high as the monopolizing powers controlling them want. There is also less competitiveness with use of solar panels since there is no fight over such things as oil fields and other raw materials. Although the government has started addressing the issue of solar panels, there is little influence they can have in price manipulation. This is because no one controls the main raw material.

There is also less environmental destruction with the use of a System Solar Panel. This is because there are no cases of mining or extraction of raw materials that eventually lead to destruction of forests and water catchment areas. With the use of solar panels, there is less of this and therefore there are steady rainfalls that greatly boost production and consequently the national income of each and every country. Many countries face problems of famine due to destruction of forests to get fuel. This can be prevented by using solar panels.

There is an advantage of reliability in using solar panels. This is because there is ability to predict the amount of sun to expect each and every day. Therefore one is has guarantee of energy. The devices are also made in such a way that they can absorb sun rays even when there a few clouds and the sun rays are not very strong. The solar energy is also renewable. It can therefore be used on and on without getting depleted. Although solar energy cannot be used at night, it operates full force during the day which is of great importance. The energy can also be stored in form of batteries for use at night.

Everyone loves some peace and quiet. This is something you get when you use solar panels. This is because they are very silent. There is no noise that gives away the fact that the System Solar Panel is there apart from the fact that you can see it. This is a good thing since it makes the environment peaceful compared to wind and water generated power supplies which have moveable parts that are quite loud and destruct the peace. Solar panels are therefore good for use for people living in estates where hoses are close to each other. This is because with silence, peace is maintained between the neighbors.

When installing solar panels, there is no large scale installation required. They therefore require very little space to install. This is very important when it comes to fast growing regions and towns. The installation will mainly involve a single cell to continually generate energy. Hence a homestead requires a single cell. There is therefore no congestion and a continued supply to the high demand of energy. This maintains a good image in a community since crowding may make the place less attractive which may prevent people from moving to the area since everyone wants to live somewhere they consider beautiful, for this reason, use of solar panels does not interfere with real estate sales.

Solar panels are durable. This is because there are no moving parts in the device. This therefore reduces the chance of it being destructed. It is possible to use a System Solar Panel for a very long period of time without having to purchase another, studies estimate that it can last for over ten years. Such a device is beneficial because it reduces the stress that comes about when a machine stops running because something became lose or worn out. There is also reduced maintenance cost since it is less prone to wear. This generally makes the device very easy to handle for a person with very little skills in handling a System Solar Panel.

Many companies that invest in solar energy get the advantage of higher profits. This is because they cut back on costs incurred in electricity and the rest of the profits are in most cases used to expand the business. This is very advantageous. Statistics show that the companies that use solar panels have greater returns compared to those that use other sources of energy. This may be due to the fact that electricity can be very expensive and may make these companies not afford allot of assets. This is especially evident in small or new companies. There is also an advantage that clients get when they get services from a company that uses clean energy. This is the fact that they can get access to government incentives that are made available to these companies.

Use of solar panels enables individuals and companies to enjoy the benefits of low taxes. This is because in most parts of the world, the taxes that are charged are about thirty percent less as compared to using other sources of energy. With all the taxes that one has to pay for every item purchased, this is a great opportunity to reduce spending on taxes. Since there is no monthly bill when using a System Solar Panel, it makes it tax free. When using fossil fuel energy, this is no option since one has to pay their electricity on a monthly basis which in most cases is heavily taxed.

The size of System Solar Panel required per meter to give maximum energy small. When there is full sun, one is able to get about one thousand watts per meter. This is equivalent to about 2900-watt hours per day. However this depends on the area in which you are locates, the time of the year and the strength in which the sun rays reach the System Solar Panel. For this reason, there are times where one gets more energy compared to others. However the energy gives the desired effect even at low intensity and is therefore still very reliable.

It is highly unlikely to hear that someone got injured when using a System Solar Panel. This is because there are few cases of electric shocks that are very frequent when using other sources of electricity. It is therefore safe to use solar panels for people. This creates fewer incidences of emergencies. However, careful measures should be taken as directed by the person that does the installation since there are instances where cables are left bare and could cause shock when touched. This is rare when the wiring is done correctly. Care should also be taken since the roof could be constantly emitting electricity.

Solar panels are not prone to destruction by harsh environmental conditions. For this reason, they are not easily destructed, this is important since the device is placed outside in order to absorb sun rays. The good thing about this is that it can be used by people who live in areas where the weather is up and down in most cases.

All these are great advantages that come with using solar panels. Solar panels can be used in any setting, whether in schools, homes or companies

Brits Shown to Favor Green Home Improvements

Eco-friendly home improvements appear to be increasingly sought-after by Britons, it has been reported.

In research carried out by Legal & General as a part of its ongoing Changing Face of British Homes study, it was revealed that making greener changes to lifestyles is an evermore popular option for members of the public. The study showed that some 37 per cent of people have installed either draught-proofing or double glazing. Meanwhile, 25 per cent of respondents were shown to have fitted additional loft insulation.

For those consumers looking for an effective way to carry out eco-friendly improvements to their property, such as double-glazing and loft insulation, taking out a low-cost home loan may be useful.

The study also showed that just under three-quarters of Britons use low-energy light bulbs, with 23 per cent of respondents looking to recycle rain water. Making sure electrical appliances are not left on standby and making use of reusable shopping bags were also revealed to be popular eco-friendly lifestyle changes. Meanwhile, recycling rubbish was indicated as the most sought-after means in which people lead a greener lifestyle. Overall, 98 per cent of people claimed to be taking steps to improve their environmental efficiency.

However, it appears a significant number of Britons only want to make environmentally-friendly changes when it suits them, with more than half of those questioned said to be unhappy about being charged for waste removal services. An estimated 23 per cent are said to be irked at having to pay for plastic carrier bags at supermarkets and shops.

Commenting on the figures, Ruth Wilkins, head of communications for Legal & General’s general insurance business, said: “While people are annoyed by the implementation of green initiatives the efforts being made to force residents to recycle more of their rubbish are beginning to pay off, with recycling rates jumping from seven per cent to 33 per cent in the past ten years. Legal & General’s recent research would support these findings as the Changing Face of British Homes research shows that a large number of us are taking steps to become greener. Brits simply want to make their own decisions regarding how and when to be green.”

Ms Wilkins went on to report that it is important for those homeowners thinking about carrying out major improvements to their property which are of an environmentally-friendly nature “to check their insurance cover to make sure they are covered under the terms of their policy”.

For consumers wishing to renovate their house – and at the same time help take steps to save the environment – applying for a homeowner loan could be useful. In obtaining this kind of home loan it may be possible that the cost of installing eco-friendly improvements – such as cavity wall insulation, biomass heaters, draught proofing and solar heating panels – can be met quickly and affordably. Indeed borrowing for the purposes of financing home improvements could be rising in popularity after a recent Lloyds TSB study revealed a 19 per cent increase in loan applications for such purposes this month in comparison to August 2007.
