Swapping to solar power is becoming increasingly popular as the cost of traditional energy is on the increase. This combined with the move to greener fuels to protect the global environment make solar an attractive option.
Here are three things to consider before you go solar.
1. Is your roof suitable – The obvious place for solar panels is on the roof. Depending on the direction and angle of the roof you will get different amounts of exposure to direct sunlight. It is important to maximize your panels exposure so that you will have sufficient power during the darker winter months.
Do not worry about other weather conditions too much. Rain will not hurt your panels, and will in fact help to keep them clean. Equally, your solar panels will be angled so snow should slide off.
2. Buying your solar panel kit – There is no easier way to convert to solar panels than with a solar panel kit. You do not want to have other expenses, so it is worth investing in a good kit. Check out review and what you get before you buy.
There may be bargains out there, but don’t get too carried away. You can be sure there is a significant difference between the expensive and cheap kits, so be sure you know what you may be compromising on.
3. How much will it cost to change to solar power? Across the world governments are panicking about the effects of global warming, so they are doing everything possible to covert people to greener energy sources. It is worth researching to see if you qualify for any of the grants which are currently available.
So where do you start? A good place is the manufacturers of solar panel kits. It is best to try to find a regional office. The people in local offices will be aware of the style of houses, the climate and will probably also know what grants are available in your area. These manufacturers want you to use there product so you will probably find them extremely helpful.

Following you will find 5 tips to help reduce your utility bill year round with or without the use of wind power. Hopefully these will help you to make ends meet, especially for those who are already unemployed or fear unemployment is a round the corner.
1. Whether you live in a mild climate and use your furnace more than the a/c or in a hot climate and use the a/c more than the furnace, it is important to have your a/c and furnace serviced once a year. Having the units serviced yearly can keep them running efficiently, saving money, and can keep them in good running condition prolonging their life, again, saving you money on a repair bill. On top of having your units serviced regularly, change the filter once a month, more frequently in dusty environments. A dirty filter, even if it is only partially dirty will make both the a/c and furnace work hard, wasting energy and money.
2. Consider replacing your manual thermostat with a programmable one. There are many who try to save energy and money by turning the thermostat way down in the winter when they leave the house, or way up in the summer, and this fine as long you do not go to extremes. Turning the temperature way up or way down will cause the furnace or a/c to run excessively to bring the temperature back to a comfortable level. Changing the thermostat manually works good if you don’t forget to do it, which is why I suggested replacing the old manual one with a programmable one, set it and forget it until the seasons change, this way you gain maximum benefits and savings.
3. Seal air leaks by taking a trip to the hardware store and pick up caulk and outdoor outlet gaskets (the ones they use behind the outlet covers on outdoor outlets and switches) caulk around doors and windows. Then remove the covers on all the outlets and light switches located on outside walls, and then place a gasket over the outlet or switch then, reinstall the cover. Now take a sharp utility knife and carefully cut off the excess gasket that sticks out from under the cover (they are generally made of foam.)
4. This will only apply if you have and use a fireplace, and is more of a precaution than a savings tip. Using a fireplace, if you have one, can save you a considerable amount of money in the winter. However, the more you use it the higher build up of creosote you will get, and if you do not have the chimney cleaned regularly you stand the chance of chimney fires. Another thing you should look at is the top of the chimney, is there a screen cover and cap. If there isn’t you have the possibility of birds, that sit on the chimney for warmth, becoming overcome by fumes and falling in the chimney which can block it causing smoke to backup into the house.
5. This is not really a tip as much as a suggestion, (wind power) a windmill in the backyard can produce almost enough power to eliminate your power bill. All you need for the windmill to be economical is live in place that has a minimum of 11 mph winds and live on enough land to erect it. With a windmill and the above tips, you will save more money than you would believe is possible.
With the cost of living rising every day and threat of losing your job, it is even more important to use to reduce your utility bill. to discover affordable ways to use renewable energy sources.
Are there any alternative energy sources that can fulfill all the demands on energy? Discussions on global warming bring up the issue of fossil fuels and their escalating prices. The concern about the availability of these fuels for future generations is also a common discussion. Many people hardly find it an easy choice when they are given a chance to use either conventional energy or the new sources of energy. Sources of recycled energy are many and how this energy is used varies from vehicles powered by bio-diesel, electric cars, to solar lighting etc.
If you would like to give alternative energy sources a chance, you will discover that most of these alternative options are quite expensive. Since a lot of people are still using the conventional fuels, you do not really know who to turn to when you need help on those the alternative sources. The companies providing these alternative energy sources have customer care centers, but a tip from a neighbor will lack.
Those people who have tried to invest in alternative energy sources have ended up being discouraged because the options they got were very expensive. The other issue that is most probable to arise is the fact that not many people are into it so this minimizes the place to go for help in case it is required. Although there may be customer care centers to offer help, a piece of advice or two from your neighbor could also be of great essence.
Several companies which produce cars have manufactured hybrid models while others have introduced cars that run on electricity and bio fuel. These models are not useable in everyday life due to the limited availability of bio-fuel coupled with the limited technology used on the models. However, these situations are gradually changing. Some countries actually have commercial vehicles that run only on compressed natural gas. BMW has introduced a car that runs on electricity and only runs on gasoline if the battery is out. REVA is another car manufacturer that produces electric cars only. Their latest models can go up to 100 miles on single charge, and the charging time is less than one and a half hours. These are the advancements that will encourage the people to make use of alternative energy sources.
Companies that assemble motor vehicles have also not been left behind. Introduction of hybrid models to replace those that use electricity and bio-fuels has already been implemented in certain states. The use of such cars was not feasible for daily use because of their limited technological development and the availability of bio-fuels. Use of CNG which stands for Compressed Natural Gas is in the forefront by public service vehicles and buses in European countries. A perfect example is the BMW car which runs on an electronic battery and once the battery id off, it can result to gasoline. It was invented and introduced into the market in 2008. REVA is another car manufacturer which has come up with two latest models for 2010. They both can go for over 1000 miles upon a single charge. Recharging their battery only takes 90 minutes or less. It is such advancements that will influence more citizens to buy cars that use alternative energy sources.
Several advantages of having alternative energy sources including saving on fuel prices, reducing the amount of poisonous emissions thereby contributing to the solution for global warming. Though these sources are expensive, their prices will reduce drastically once the market becomes big enough. In addition, they are a lot cheaper once installed.

After you purchase your solar panels, you will be faced with some decisions about their installation. How will your solar panels be mounted? What parts will you need? If you are like me, then no matter which direction you choose the system should be reliable and secure.
A popular method is to mount one’s solar panels on top of their roof. It is a simple and convenient solution, and so most folks attach their solar panels this way. Most often these mounting parts can be purchased right off the shelf.
We would like to point out a couple issues with mounting solar panels on the roof, however. They are things to keep in mind for folks who live in northern climates, or who desire more optimal performance.
The first issue we encountered was dealing with snow. Snow storms are common in my neck of the woods, and sometimes there is snow pack all Winter long. Whenever there is the slightest amount of snow fall, the solar panels must be cleaned. Snow covered glass will severely inhibit their ability to produce electricity.
In the mountains of Washington and Colorado, we have been working on a solution. We are designers and craftsman who desire convenience and performance with our own home based solar power systems. And like everyone else, we don’t want to spend an arm and a leg. We call this solution the Rotek system.
In a Rotek installation, the solar panels are mounted on a ground based structure instead of the roof. This provides the clearances for adjustability, so that we can rotate the solar panels in any way. With this in place we can make seasonal adjustments to match the Sun.
In the Winter is when this adjustability can be a big help. The solar panels can be pitched more steeply or rotated toward the ground (negative tilt) to keep the snow off the surface. It is also good for giving the glass an occasional cleaning.
Whether for one snow storm or for a period of weeks, as long as there is snow on the ground you can leave your solar panels at negative tilt. As we have all witnessed, snow pack is highly reflective. Your system will continue to receive lots of beam radiation despite this abnormal tracking angle.
The second big issue to consider is heat. As our roofs accumulate heat, they will increase the operating temperature of a roof mounted solar panel. Performance tests have shown that higher operating temperatures will reduce the solar panel’s discharge current. This lost current output can be as high as 2 or 3 amps depending on the unit, which correlates to better than 20% energy lost against baseline operation.
Remotely mounted solar panels with Rotek system will dissipate heat, run cooler, and give you better performance. This is because of fresh air circulating on the back end, instead of a warm insulated roof. This reduced operating temperature will also decrease wear and tear and help increase the longevity of your system.
So now that the decision is made to install your solar panel system, you must choose a mounting configuration. The roof mounted options are simple and in many cases a good choice. For those who want a little more performance and design flexibility, the Rotek system is a reliable and inexpensive alternative worthy of consideration.

We use the words thermal solar power to describe any system designed to convert solar radiation into thermal energy. It is one of the major players in the solar power market and has huge untapped potentials.
The uses for thermal solar power are widespread and varied. Just think of any process which could utilize heat. This could range from something simple such as hot water heating, to more sophisticated designs involve stirling engines or industrial grade steam.
For most folks, thermal solar power will be limited to heating up a hot water tank, or storing heat for the workshop or house. These systems are inexpensive to incorporate, especially when designing a new home.
There are other good uses for thermal solar power which we expect to increase in years to come. One is pebble bed heat exchangers, which act as a thermal storage bank for converted heat. This gives us some system capacity and operating flexibility.
Pebble bed heat exchangers can be used in a variety of ways. They can be wall mounted units, or embedded in the floor. They can provide the heat source for everything from a family room, to a workshop, greenhouse, or dry sauna installation. They have good aesthetic qualities, being composed of natural materials, and can be incorporated in an attractive way into any home.
The typical operating temperature for most thermal solar power systems will be between 100F and 180F. In good solar climates these temperatures can be easily achieved with popular off the shelf equipment. With more specialized equipment we can go in excess of 250F, and with high performance industrial equipment over 700 degrees is possible. These high performance systems are usually for making steam, but incorporating them into other processes is also possible.
Solar collectors are designed to achieve a certain operating temperature. Flat plate and evacuated tube collectors are very effective at lower system temperatures. Parabolic trough and concentrating collectors are required for higher system temperatures. The solar collector is quite possibly the most important component in your thermal solar power system. It is the thermodynamic engine and should be selected thoroughly and carefully.
The lifeblood of the thermal solar power design is the circulating fluid. The circulating fluid is heated in the solar collector, and then pumped to all the system users. This fluid is typically oil, glycol, or water which is matched to the system temperatures and equipment in use.
Anyone interested in energy independence and self-sustainability should thoroughly investigate thermal solar energy. Most systems are fairly simple and rank very well in affordability. If you live in a climate with a good reputation for Sun, then there is a pretty good chance you could be using a thermal solar power system of some form.
Thermal solar power is a major branch of the solar market, with much room to grow in years to come. Solar hot water and pebble bed heat transfer systems are two good applications for most homes. We can store heat in our floors, a sauna, a greenhouse, or even use it to air dry our clothes. The possibilities for thermal solar power are as far as the imagination can go. With a new age emerging toward more natural lifestyles and self-sustainability, we expect to see several new designs in years to come. Everything begins first with harnessing the energy of the Sun.

If we are serious about decreasing environmental pollution, then solar energy should be a part of the equation it isn’t a part of the problem, so it must be part of the solution. It’s recognized as an “alternative energy source”, as it isn’t widely used as a main source of power for very many people. It’s expensive to produce solar panels, and in today’s world, calculators and lawn decor are two of the most popular solar powered gadgets used by the mainstream. So, the burning question that could maybe help solve our planet’s current dilemma is, how do solar panels work? How does a panel harness the sun’s energy and turn it into electricity?
The basic concept of how solar panels work is that they’re made from special materials that are capable of harnessing the sun’s energy and converting it into electricity. Electricity that powers electronic devices that we use in our everyday lives. But there’s a little more to it than that.
A budding technology used today for solar panels is photovoltaic (PV) electricity. It involves the use of specific materials that convert solar energy into electricity. The electricity can be used right away or it can be stored using DC batteries. Either way, we’ve got power!
These materials have been recently developed and they release electrons when prompted by sunlight. Another name for a photovoltaic panel is a “direct energy conversion device”. All of these effects take place on an atomic level without any moving parts.
Photovoltaic panels used to be restricted to space age technology. Satellites and space stations used them for their reliable and continuous conversion of solar power. Outer space has an advantage when it comes to solar energy since the sun’s radiation is, at the very least, 50% stronger out there than here on Earth.
People who live more than a mile from an electrical grid are better candidates for solar power use especially those in residential homes. It’s significantly more expensive to install power transmission cables than it is to install a solar panel kit. If you fit this criterion then solar energy to power your home is a smart way to go.
But the question hasn’t been fully answered yet”how do solar panels work?”, and to better understand this we should know what solar energy is. Solar energy is made up of two kinds of radiation. The first and the best kind for solar panels to function is called “beam radiation”. Imagine you are laying on the beach in the middle of June on a bright sunny day. Feel the sun’s rays beating down on your skin. The energy you feel on your skin is “beam radiation”. A clear blue sky is a good day at work for a solar panel, but that solar panel needs to be properly placed in order to absorb the most direct sun rays as it can to achieve optimal results.
The other kind of radiation from the sun is called “diffuse radiation”. This shouldn’t be relied on for the sole energy to be absorbed by your solar panels. This is what we feel on an overcast, cloudy day or if chilling out under a shady tree. To rely on this type of energy from the sun as your main source of sunlight is far from practical.
So, with this being understood, a bright and sunny location is key for solar panels to work effectively. Beam radiation is very important and most of Western America fits this bill. However, northern climates and coastal states pose a bit of a challenge since typical weather there consists of a lot of clouds and rainy days. Those regions aren’t prime candidates for 100% solar reliance.
Solar panels are versatile in the sense that they can be set up to meet specific needs. 12 volt, 24 volt, and 48 volt DC systems are the most widely used. 12 volt solar panels can live well over 20 years and fall in the range of 12-14% efficiency.
Solar power is still “alternative energy”, and part of that is due to its high cost to produce. They’re so expensive because they are made of supremely pure silicon semi-conductor materials. New materials are being explored and they’re geared toward lowering production costs, making solar energy more readily available to the general public. Cadmium Telluride based solar panels are one of the new technologies being explored, and if these are successful materials then solar panels should become more affordable for the average citizen. This is great news for the environment as more and more people convert to solar energy, the atmosphere can begin to heal.
You’ll want to assess your weather patterns as well as your local utility rates before making a final decision as to whether or not to install a solar panel system at your residence, but the benefits to the environment truly outweigh the monetary aspect. The decision is much simpler if you intend to use solar merely as a backup plan. Energy independence is a common goal for all. It helps the environment in so many ways that simply can’t be ignored.
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 is decreasing. To make it even more affordable you can craft your own .
More of us than ever are concerned with both protecting the environment and our wallets. People used to think that using alternative energies would simply be too costly to ever be practical, but with the rising costs of energy, many are starting to change their position.
Truly though, even if you have to spend a little bit of money getting something such as a wind generator set in place, you will save so much money on your electric bill that it will truly pay for itself over time. There are even a lot of programs out there that could possibly help reimburse you for the expenses you incurred from the installation of such generators.
There are programs offered by states and even some cities which can help you to save on the cost of doing the right thing for the planet. A wind generator will more than pay for itself over time anyway. Other than the savings you’ll see on your electric bill, you can sell any surplus energy to your local utility!
Electricity suppliers are required to buy the extra energy generated by consumers who use wind generators and other alternative energy sources who produce more than they can use. You’ll be doing your part by powering your home with clean energy and by selling the excess to your local utility; you’re also supplying clean renewable energy to other households in your area!
You can even make a little bit of money by using wind power, so everyone wins here. Wind generators are easy to install as well. You can find instructions which take you step by step through the process on installation, so there’s no need to worry. It’s easy enough for anyone to do and if you’re installing your generators in your roof, you should be able to generate enough energy to meet your home’s energy needs.
What about a back up plan? If you live somewhere where they can be times of very little wind, you can fall back on the utility company. Simply do not disconnect your hook up to the electric company just in case you ever need to fall back on them. This will ensure that you are never left without the electricity you need to run your home in a safe and pleasurable way.
You’ll also want to stay connected to your local utility company because this allows you to sell them your surplus electricity. When you make more than you can use with your wind generator (which will be more often than not), then you can sell the extra. You’ll also be using clean energy and helping others to do the same. Naturally, the larger the turbines you install, the more power you’ll produce.
This does not mean that you have to go with the largest that is out there though if that is not something you can afford at this time. Over time, you can add more and more generators, or larger ones, and you will be able to see that you are bringing in much more renewable energy.

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 .
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.

The Sun is like a giant power station, making solar energy for us each and every day. Without this daily dose of solar power, Earth would not be even close to the same. Literally the difference would be like night and day.
Electromagnetic radiation is the technical term for solar energy. This radiation is emitted by the sun and is absorbed into Earths biosphere in many ways. Because of its widespread importance to the biosphere, solar energy plays a crucial role to our existence.
Electromagnetic (EM) radiation comes in many different wavelengths. We describe EM radiation based on its wavelength with Gamma rays being the shortest, and Radio waves the longest. Earths solar energy falls in the middle, composed of infrared, ultraviolet, and visible light waves. This is a good thing because all wavelengths between Gamma rays and Ultraviolet rays are harmful to humans and most other things on Earth.
Solar energy plays a primary role in all biological and thermal interactions on the Earth. With the presence of carbon dioxide, water, and solar energy, plants are able to produce energy through a process called Photosynthesis.
Solar energy is also the primary element that forms weather patterns. The Sun warms the surface of the earth, whereby wind patterns develop. Solar energy is absorbed in the oceans, and this helps form the currents. Evaporation caused by solar energy is what fundamentally leads to clouds and thunderstorms.
And so it is no surprise that solar energy is at the root of almost all physical processes that occur on Earth. Without this valuable resource life as we know it would not exist.
Each and every day we should all be giving thanks to the Sun. It may be the most important element to our existence which we take for granted. Imagine if one day we woke up and there was no Sun? It would be like losing power at your home, but a million times worse. Probably most people would fall into an immediate panic.
Thinking about it like that, we should probably all wake in the Morning and give thanks to the Sun. It is the single item in our existence we take most for granted. What if the Sun disappeared for one day? Just think of the mayhem and chaos this would create. And think of all the solar energy that would be lost all over the world.
With the recent advances in materials and industry, we now find ourselves with some new inventions for working with solar energy. It is now possible to make electricity directly from sunlight in a photovoltaic device. We can harness solar energy in absorption and concentrating collectors and store the heat.
The modern home can benefit greatly from solar technology, and the implementation has only just begun. Whether retrofitting your house, or building a new home, harnessing solar energy can bring tremendous savings and true energy independence. As a side benefit, we can feel good about lessening our impact on the environment.
With all the choices on the market its hard to know exactly where to start. What kind of benefits can be obtained by harnessing solar energy? How practical is it, and how much money can be saved in the long run? The truth is, in utilizing solar energy everybody will have a different idea and different purpose. Its best to begin with a discussion of the various technologies and their rewards, and allow the reader to form his own concepts for moving forward.
