Help The Environment With Solar Panels For Your Home

February 13th, 2010

More of us are now concerned about the source of the electricity we use. There are daily news stories about the consequences of burning fossil fuels that have brought the state of the environment into everybody’s mind. But today most of the energy we use is still produced in power plants that burn coal and oil which add to the amount of greenhouse gas present in our planet’s atmosphere. You can choose to switch to a “green technology” such as solar panels for your home that will not be adding to global warming or climate change.

There are many benefits that can be had by using solar energy for your home. Of course there will be immediate savings to your annual energy bills but did you also realise that you may be also eligible for certain tax breaks and benefits from your local authority. Every state government is now trying to encourage citizens to switch to green practices. You may often be able to acquire a grant to cover the cost of the installation.

Solar panels can also be an excellent purchase if you have a property that is not connected to the national grid or which is in area prone to power cuts and shortages. In this day and age there really is no need for us to rely on our government and utility companies to provide us with a necessity such as electricity.

Even just five years ago photovoltaic cells were not so efficient. This has forever changed as there have been rapid advances in the field of solar technology. Now even on a rainy or cloudy day the cells will be able to produce enough electricity to make a difference.

You can install solar panels that will produce a small percentage of your electricity requirements or it is also possible to fix up a series of panels so that your energy needs are met independently of the national power grid.

There are professional tradesmen that can install the panels on your property or if you understand DIY it is not such a complicated job to do yourself.

The price of solar panels is decreasing. To make it even more affordable you can craft your own do it yourself solar panels.

How Electricity Is Produced From Wind Energy

February 8th, 2010

Wind energy has been used for many years as individuals have used wind power for sailing, wind mills for manufacturing and pumping water and more recently conversion into electricity using wind turbines. Wind power is a renewable energy that is considered a good option instead of burning fossil fuels. Of all the renewable energy sources it is the most efficient and you only need a light breeze to produce electricity.

The very first uses of wind for energy was in the form of wind mills and sailing as people have been using wind for more than thousands of years to propel ships. Windmills have also been used for many years for milling grain as well as pumping water for irrigation. These irrigation windmills was the main reason that farming and ranching could occur in the US, as there are vast stretches of land that do not have ready access to water.

The very first usage of wind to create electricity occurred in 1888. The first wind turbine was used to create hydrogen in the 1890s but it was soon converted to producing electricity. Small wind turbines are used to provide power to rural buildings and today there are larger wind farms that are being used to produce electricity for large networks. What is known as the modern wind industry really began in 1979 when wind turbines began to be regularly produced.

Wind occurs because the surface of the earth is not evenly heated, as the poles get less sunlight than the equator. This causes cooled and heated air to move which in turn produces wind. It is projected that the amount of power that could be harnessed form the wind is more than the human population currently uses. So just think about having almost cost free power.

The amount of power that is generated by the wind is dependent on the speed and as the wind speed doubles the amount of power produced increases eight fold. However there is a cap as wind turbines can only go so fast and generate so much energy. You do not need high winds at all time though as a lot of energy can still be produced with 15 mph breezes. As such, wind power is a valuable method for alternative energy.

The main issue with wind energy is storage as wind power cannot be dispatched at different times but needs to be used immediately. Many companies have looked into different types of batteries, storing it within the energy grid and even hydroelectricity. Many times surplus energy from domestic wind turbines are fed back into the electrical grid and the energy company will purchase this energy and you will receive electricity credits.

A wind turbine used to collect the power of wind will contain a rotor shaft, gearbox and brake assembly. Generally within a wind farm the different turbines are interconnecting for power collection and communication networking. Wind energy uses induction generators to collect the power and change it to electricity.

The best types of generators are doubly fed machines as they will function when errors occur within the grid. You need to be aware of the power factor, dynamic behavior and frequency constancy when a system fault should occur.

Wind power should be thoroughly considered in order to promote a greener society. Educate your children to become future scientists by purchasing them science lab equipment.

Phoenix Solar Panels: Are They Worth The Cost

February 4th, 2010

Phoenix solar panels should be a common feature on most homes. Solar energy is a great technology. Generating electricity from the sun, what a concept? Where in the United States would there be more sun than in a desert state?

Capturing the sun’s energy to power your home during the warmer months will help cut energy costs in the colder months. People who do use the panels can also sell their excess energy back to their utility company in credit units. This will help regulate monthly electricity bills during the colder months.

Arizona can be a hot, humid state. That is why many people relocate there due to health issues. It is almost always sunny in Phoenix so you would think that people could live off of the sun’s energy without ever having to rely on power from utility companies. Surprisingly there is not an abundance of residential homes with solar panels there.

The government offered tax credits to residents to participate in the program, but the cost even with the tax credit was more than most of the populace can afford. It is the cost of the panels that has kept the installations to a minimum in most areas. The larger companies are the ones who are taking advantage of this technology. But then they can afford to put out that kind of money.

Even though you pay a lot of money for these panels they still require maintenance. They are prone to cracking. They tend to work better in cooler, sunny weather than in extremely hot locations.

Arizona’s utility company is getting on the band wagon. They are offering free solar panel installation to a small number of customers to entice other customers in the future. Renewable energy requirements are not being met and this project will help them meet their goals.

DIY Clean Energy – How To Build Your Own Solar Panels

January 31st, 2010

With continuing price rises on energy, solar panel is coming more to the fore; providing practically free power. It can be expensive to have these installed however, so is a good idea to build your own solar panel.

The first thing is ensure you have the necessary tools and equipment. This will mean sourcing the best solar cells for you, which should be given a good portion of time to decide. There are many out there.

There are a few other items needed. Plywood, a length of 1 x1, copper wire, a diode line, batteries and Plexiglas will be required for construction. You will also need a circular saw, screws and screwdriver, caulk, outdoor paint, soldering kit and glue.

Using your chosen cells as a guide, draw a grid on the plywood. Once satisfied, saw out the entire base and place to one side. It is now time to construct the actual panel itself.

Take your 1 x 1 and cut to size; determined by the size of your plywood panel. The panel should be attached to these using your screws, and applying suitable amounts of caulk and painted with outdoor paint to protect from the elements.

Before applying the cells, they need to be soldered together; using tabs at the back to attach one to the other. This work needs to be very careful, as the cells are very delicate at this point. Once in a suitable series, they can be applied with glue onto your plywood grid.

Once all set into place, the copper wire and diode line can be attached from the panel to the electrical system. The diode is necessary here, as it will prevent power being lost through reverse transfer from the batteries.

The final step is to entirely weatherproof the panel through Plexiglas over the cells. Secure in place with caulk and allow to dry. You have now managed to build your own solar panel.

By learning how to make a solar panel you can save money, help the environment, and generate electricity using free energy from the sun with DIY solar panels.

Exploring and transforming alternative energy resources

November 20th, 2009

We don’t notice it often since we are so focused on petroleum and its derivatives, but there are many other alternative sources of energy which are in abundance on our planet. These sources are virtually in exhaustible and have been used across the globe in many different forms. However, they have just been used in lieu or the deficiency of petroleum and not as the primary sources.

Energy sources like the wind, sun and the geothermal are inexhaustible no matter how much we may use them, however we need to know and understand how to harness them and turn them into the kind of power that we need. This has become particularly more important because the fossil fuels are getting depleted fast and we need to turn to alternative energy sources to meet all our requirements.

Harnessing alternative energy sources for energy is not that tough particularly if you have a look at the progress which has been made in trying to convert fossil fuels into petroleum and other such products by purifying and refining them. The entire procedure is an expensive and tough affair and naturally costs more millions!

Though migrating or shifting to a new source of energy may be an alien concept since we are so used to petroleum, the truth is that it is essential for the progress and health of our planet. This step will help us in controlling pollution, decrease global warming and even help us to continue living in the same kind of lifestyle that we have been used to.

Solar power is a renewable form of energy. Harnessing this form of energy involves buying apparatus which initially is more costly than harnessing the energy provided by the conventional fuels. However, we need to take this difference into our stride because this will happen when we make a change from conventional to non-conventional sources of energy. It’s not practical to think that we can just switch to the renewable sources and just do away with all the conventional sources of energy overnight. The change will be expensive ad gradual.

From the time of Michael Faraday, the British Scientist who is known as the father of electricity in’00s till today, nothing is really changed as far electricity generation is concerned. Despite the fact that electrical energy can be generated in seven different ways, till today the transforming kinetic energy into electricity or the electromagnetic induction method still remains the most popular. Utilizing these new forms of energy will require a look at the fundamentals, re education of the basic principles and a lot of learning.

These days the technology using photovoltaic devices has seen some rapid progress. However, the basic issue with the photovoltaic solar panels is that they are naturally more expensive than the electricity generated from the conventional sources of energy. Nevertheless, now there is a 40% leap in the capacity in places like New Jersey, Germany, California and Japan. With the kind of progress that is happening, it is hoped that it won’t be very long when solar power will be at par with petroleum in terms of the efficiency and the cost.

New methods, products and visiting old mistakes can help us to understand new ways of power creation. Children are being educated in school about the importance of the earth, sun and wind and the ill effects of pollution on our planet. In a nutshell, the faster we understand how to harness these renewable sources of energy, the happier we and this planet will be!

Solar panels are able to transform energy by using photovoltaic technology. Utilizing photovoltaic cells, it can manipulate the solar energy gathered from the sunlight and then converts it to solar electricity so we can use it as an energy source for our equipments.

With the solar cells inside the solar panel, the rays of the sun will be collected, transformed and converted into what we all know as solar electricity. The direct current that is created comes from the electrical charges. These charges are possible because photovoltaic goes through the semi conductors that are made from a special kind of silicon which creates the charges every-time light hits it.

Now why is the use of solar electricity advocated in many parts of the world?

Operation of solar energy systems are very easy, smooth to handle and also very silent when running compared to other alternative energy sources. The most valued reason to use solar electricity is that the process to produce solar power does not release greenhouse gases which makes it a very valuable especially in this age and time. Who wouldn’t want to save the planet right? In a long term perspective, you will only contribute to it more and it would give you more savings every month.

So how can we start using solar electricity?

The first thing you will need are solar panels. As has been said before, this is the single most important part of your system as it will be absorbing the sunlight everyday. The price will depend on the amount of energy you will need and the installation will also have an extra cost but it is still affordable.

But if you’re working on a tight budget, never worry since you can build your own solar panels to produce solar electricity by just few clicks on the internet.

With the help of alternative energy like solar electricity, you can save money and of course, the environment. This will certainly make the lives of our children a better one. So start today and give back to the world. You will never regret it.
