Generate Your Own Electricity With Solar Power System

Our power bills are slowly but surely rising, during the summer months we use more electricity because we need to cool down the house and ourselves. People are starting to look for alternative energy sources because they just do not want to pay that much. A DIY solar power system look like a promising technology and if your house is located in good spot then it is a good idea to invest. By investing an purchasing PV cells or building solar panel you can cut down on your electrical costs. Though you need an initial investment and yes this will come back pretty soon especially during the summer months.

Before we start dissecting a solar panel to figure out how it works we should understand the nature of light. The light is made out of photons this particles are fast moving atoms. Our Sun is bombarding Earth by the trillions each moment. Photons move with the speed of light because they have a lot of energy and our goal is to harness this energy and produce electricity. It is an interesting fact that on a clear day at sea level 1KWh falls on a square meter and this is enough energy to power up most of the household equipment in an average home.

Photons can interact with matter in a couple of ways: they can be reflected when it hits a mirror, it can be absorbed so it is energy is turned either in heat or electricity, it also can suffer transmission when it does not lose any energy just goes through, this is the case of windows, and last there is the effect of scattering when the photon interacts with molecules in way that it forms a rainbow thus dispersing its energy.

Now solar power can be harnessed in two different ways you either use it for heating or generate electricity. When solar power is converted to heat the next thing to do is to transport it to the place where you need it and this is done by conduction or by convection. When the heat reaches it is target destination it will be used to heat up swimming pools, cook, make tea and so on and so forth. When electricity is created they use photovoltaic cells PV for short. These crystals are made out of semiconductors which when they come in contact with photons they produce electricity. You most likely have seen PV cells on you calculators which do not use any batteries or on ecologically friendly houses and businesses. The Sun will be shining for the next 6 billion years so we do not have to worry that there won't be enough energy to go around.

Future Proof Your Solar Power System

You do need to consider the future when you build your own solar power system. The system will have a lifetime of 20 years plus, so you need to ensure – as far as possible – that the system will be effective for that length of time.

When scanning the horizon, take into account that trees and hedges will grow during the lifetime of the system. A small spruce in a nearby garden now could grow into a monster in the space of a few years, and if that is a risk it is best to know about that now rather than have a nasty surprise a few years down the line.

See if there are any applications for building work to be carried out and try to assess the likelihood of future building work that could have an impact on shading.

It is also worth finding out if fog or heavy mist is a problem at certain times of the year. If the site has regular problems with heavy mist, the efficiency of your solar array will be compromised.

What if there are obstructions?

If there are obstructions, you need to ascertain at what point during the day the obstruction occur.

Anything due south is a major problem as this will be the position of the sun when the intensity of the sunlight is at its highest. Core power generation occurs between 9am and 3pm. If you have shading either before 9am or after 3pm, you’ll lose around 20% of your capability or 40% of your capability if you have shading both before 9am and after 3pm.

During the winter, the difference is not so great – if you have shading before 9am or after 3pm during the winter, you’ll probably be losing only around 10% of your generating capabilities during this time.

If you have shading during your core power generation times, you need to give serious thought as to whether you should continue with a solar implementation: the performance of your solar system will be severely compromised. You may be better off investigating other energy options such as wind power or fuel cells, either instead of using solar or in combination with a smaller solar electric system.

Alternatively, if obstructions occur for part of the day - such as during the morning or during the afternoon, you can consider increasing the number of solar panels you purchase and angling them away from the obstruction to increase their collection of sunlight during the unobstructed parts of the day.

The final option if there are obstructions is to use a solar tracker in order to improve the efficiency of your DIY solar panel throughout the day.

When Do You Need To Use The Solar Power System?

It is important to work out at what times of year you will most be using your home solar power systems. For instance, if you are planning to use your system full time during the depths of winter, your solar power system needs to be able to generate electricity even during the dull days of winter.

A holiday home is often in regular use during the spring, summer and autumn, but quite often left empty for periods of time during the winter.

This means that during winter, we don’t need our solar power system to provide enough electricity for full occupancy – just so long as the batteries are large enough to provide enough electricity for the occasional long weekend, with the solar array recharging the batteries again once the home is vacated.

We could also decide that if additional electricity in winter was required we could have a small standby generator on hand to give the batteries a boost charge.

For the purposes of our holiday home, our system must provide enough electricity for full occupancy from March through October and occasional weekend use from November until February.

How To Operate Your Solar Power System The Right Way

For a solar power system to work well, we need the site survey to answer two questions:

• Is there anywhere on the site that is suitable for positioning my solar array?
• Do nearby obstacles such as trees and buildings shade out too much sunlight?

The first question might at first sound daft, but depending on your project it can make the difference between a solar power system being system being viable or not.

By answering the second question, you can identify how much of the available sunlight you will be able to capture. It is vitally important that this question is answered, as the number one reason for home solar power systems failing to reach expectations is due to obstacles blocking the sun, dramatically reducing the efficiency of the system.

To fully answer the second question, we need t be able to plot the position of the sun through the sky at different times of the year. During the winter, the sun is much lower in the sky than it is during the summer months, and it is important to ensure that direct sunlight is not blocked from the solar array during the winter time.

Solar Electricity and The Environment

Solar power systems are low carbon electricity generators: the sunlight is free and the system maintenance is extremely low.

There is a carbon footprint associated with the manufacture of solar panels, and in the past this footprint has been quite high – mainly due to the relatively small volumes of panels being manufactured and chemicals required for the ‘doping’ of the silicon in the panels.

Thanks to improved manufacturing techniques and the higher volumes of panels now being produced, the carbon footprint of solar panels is now significantly reduced. Most manufacturers claim the carbon footprint of new solar panels can be recouped through the power generation from the panels within 2-5 years.

Therefore, it is true to say that solar power system that runs as a complete stand alone system can reduce our carbon footprint.

Grid tied solar systems are slightly different in their environmental benefit and their environmental payback varies quite dramatically from region to region, depending on a number of factors:

• How electricity is generated by the utilities in your area (coal, gas,
• Whether or not your electricity generation coincides with the peak electricity demand in your area (such as air conditioning usage in hot climates, or high electrical usage by heavy industry in your area)

It is therefore much more difficult to put an accurate environmental perspective, you should try to achieve the following:

Use the power you generate yourself as it is being generated – especially for high load applications such as clothes washing

• Minimise your power consumption from the national utility grid during peak times (typically during the evening in cooler climates and during the early to mid afternoon in hotter climates).

In Conclusion

• Solar electricity can be a great source of power where your power requirements are modest, there is no other source of electricity easily available and you have a good amount of sunshine available.
• Solar electricity is not the same as solar heating.
• Solar electricity absorbs photons from sunlight to generate electricity. Electricity can still be generated on cloudy days and on bright moonlit nights.
• Solar electricity is unlikely to generate enough electricity to power the average family home, unless major economies in the household power requirements are made first.
• Larger solar electric systems have a comparatively high capital cost, but the ongoing maintenance costs are very low.
• Smaller solar electric system can actually be extremely cost effective to buy and install, even when compared to mains electricity.
• Solar electricity can be much cheaper than connecting a remote building to mains electricity.

Home Solar Power Systems

Home solar power systems have been used to collect rays of sun and converted into usable electricity for many homeowners. A solar power system can be used anywhere in the world, because sun energy is available for each and every part of this world. By using this type of energy, we can provide electricity to almost all the remote areas of the world.

This option is very economical and does not make any harm to our environment. Lots of researches are going on worldwide by scientists from different countries to develop an efficient solar power system. The objective of these scientists is to replace all current sources of energy using solar energy in future.

Solar power systems provide a way to reduce your monthly electricity bill and by reducing your monthly electricity bill, you can control cost of monthly expenditure.

How is it possible?

Visible sunlight is the only requirement to generate solar energy. This light is collected and processed by solar system to generate electricity. This electricity is used by you at your home. It mean, electricity generated by solar power systems, reduces your dependency upon supplied electricity.

Solar energy generation does not produce any harmful by products and this is a big differentiator for it from other sources of energy such as fossil fuels and nuclear plants. This is a wonderful contribution towards the nature by all of us using renewable energy.

Initially you may find it a little bit expensive, but all the costs can be recovered by the saving provided by solar power panels in several months. Use of solar power systems reduces your monthly electrical bill and increases your share in saving the environment.

Utilization of sunlight to generate electricity is a very responsible way to help our environment; hence we should make this change from today. Check out some of the guides that are available to help you in building solar systems and very soon you will have a better way to see the light.

Learning how to make a solar panel can be a very satisfying and rewarding project and can save you thousands of dollars in energy expenses in the long run and at the same time a big contribution to our environment and energy crisis, however, it is very important that you use a sound and reliable step by step set of instructions designed specifically for this purpose.

If you decide to download a home study course for learning how to build a solar panel manually, make sure that it is a system designed by experts with the sole purpose to guide regular non-technical people from the very beginning until the project is up and running. Support along the process is a must.
