With the environmental disaster we are seeing unfold off the gulf of Mexico (The BP oil spill) more and more as a society we are finding our consciousness pricked into looking for cleaner and greener ways to help the environment.

For most people the idea of having their own solar system is indeed desirable, but there has always been the major stumbling block of the enormous cost of the solar panels.

Having a solar system installed can cost many thousands of dollars, money that many households simply do not have to spare, no matter how much they stand to save in the long run or how much they want to help the reduce their carbon footprints.

This alternative comes in the form of a DIY (do it yourself) kit. Now I’m sure some of you just tuned out at the thought of building your own solar panels, sounds complicated doesn’t it? Well surprisingly it isn’t, in fact it’s all most child play.

The kits come in the form of an easy to follow video series and instruction manual which you can downloaded in a matter of seconds online

All the materials you need to build your own panels are available from most hardware stores (tip: save even more money by sourcing the parts from your local salvage or junkyard). Armed with the most basic handyman skills, you can assemble your panels in just a couple of days (I recommend freeing up a weekend to give yourself ample time).

It’s a great project to get your children in on, provides them with an alternative to playing computer games all day, gives them a lesson in environmental issues and energy conservation. You won’t believe the buzz they will get when they realize the solar panel they built is powering a laptop etc.

Not only will you stand to save a lot of cash by building your own cheap solar panels as opposed to purchasing them pre built, you will also cut (depending on the number of panels you build and your homes energy needs) anywhere up to 80% (in some cases above this) off your traditional power usage, this can translate to hundreds of dollars saved on every power bill.

So whether you are looking to help reduce your carbon footprint or simply want to save a few dollars, take a look at the following link for side by side reviews of the leading DIY Solar Power Kits and build your own solar panels today.

1. This one thing many over look and should not because it can reduce your power bill considerably. Furnace and a/c maintenance, which can save you money in several ways. First, by having them maintained yearly it will prolong there life thus saving you from a costly replacement bill. Second, it will keep them in top running condition which, will keep them more energy efficient saving you money. Besides having the furnace and a/c serviced regularly, be sure you change the filter every month even if does not look dirty. A dirty filter even if it does not appear to be dirty, will cause the units to work harder cutting down on their efficiency.

2. To help save on your power bill you can turn your thermostat down in the winter when you leave for work and back up again when you get home. If you constantly find yourself forgetting to do this then, you may want to consider replacing your manual thermostat with a programmable one that can be programmed to lower the temperature at a certain time then, raise it, again at a certain time, this way you won’t need to remember to do manually. Whether you do it manually or use a programmable thermostat, the one thing you do not want to do is use extremely low temperatures in inter or extremely high temperatures in summer, as this will cause your furnace or a/c to run excessively to return the house back to a comfortable temperature, thus defeating the purpose.

3. The following can be done in a matter of hours with a few inexpensive things you will need to pick up at your local hardware store. You will need a few tubes of caulking (how many will depend on how many exterior doors and windows you have) and some foam gaskets that are used to seal outdoor outlets and switches. (again how many will depend on how many outlets and switches you have located on exterior walls) Once you have these items start by caulking around all exterior doors and windows to seal air leaks then, remove all the covers on switches and outlets that are located on exterior walls, place a gasket over the switch or outlet, replace the cover, and trim the excess off with a utility knife. The more air leaks you seal the more you will save.

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 wind power to reduce your utility bill. Click here to find easy ways to use renewable energy sources. Get a totally unique version of this article from our article submission service

Thin Film Solar Panels – Boy Is This Skinny!

Think of the solar panel you see in a solar calculator. That is a thin film solar panel. Thin film solar panels are used to a great extent in satellites. Thin film technology is currently being extended into residential and industrial use and was named one of the best inventions of 2008 by TIME magazine.

Thin film solar panels are flexible, unlike polysilicon cells found in long-established crystalline solar panels. These thin film solar panels are being labeled as next generation solar power technology.

Thin film solar panels are more resistant to hail, dust, and so on. If a segment of a crystalline solar panel is broken, the entire solar panel will stop functioning where a thin film solar panel will continue to function.

Thin film panels can also be bendable and adapted to a lot of surfaces. They can be applied in places traditional crystalline solar panels cannot be mounted on. I have even seen a thin film panel sewed on a coat that powered a MP3 player.

The draw back to thin film panels is that they do not take up as much energy because they are so slim. These panels are not nearly as efficient as conventional photovoltaic panels but they are much cheaper. Thin film solar panels are printed onto the rolled backing, eliminating many of the high energy and chemical intensive methods that are normal in conventional PV manufacturing.

Thin film solar panels are low wattage and require more space than conventional solar panels and they are more prone to degradation. In order to counteract a few of these competitive disadvantages they have versus traditional solar panels, manufacturers give better warranties for thin film panels.

The largest thin film solar photovoltaic (PV) project in the United States is the Blythe plant located 200 miles east of Los Angeles, California. The 21-megawatt solar power plant uses thin film solar cells constructed out of cadmium telluride. At full power, the plant will create enough electricity to power an anticipated 17,000 houses.

Now let us look at conventional solar panels and several of the mounting options that are available you may have never heard of before.

Mounting Selections For Conventional Solar Panels – It’s All In the Mount

Solar panel mounts are available in three main varieties: pole mounts, roof-ground mounts, and flush mounts. With these mounts, you can fix your solar panel on your roof, onto an RV, on top of or against the side of a pole, or even install them as a free-standing unit.

Pole Mounts – No That Isn’t What Santa Claus Uses For His Sleigh

Pole mounts, especially top-of-pole, have been popular for a long time. Top-of-pole mounts are basically a steel or aluminum rack and rail structure bolted or welded to a large sleeve that sets on top of a pole with set-bolts to keep it in place. Side-of-pole mounts are usually used when you need to mount to the side of a telephone pole or communications tower. Tracking mounts are similar to top-of-pole mounts, but they also have a system of automatically aiming the mount to track the sun.

Top of pole mounts (as well as sun trackers) are one of the simplest mounts to install. They basically only need a single steel pole set in the ground (usually in concrete), and the mount slips onto the top of the pole. Most common sizes use a 2-inch to 8-inch pole, usually around 11 to 13 feet in length. They can go higher if you need to get the panel up higher to get out of shading from close by undergrowth.

Common Roof-Ground Mounts

Roof-ground systems can be mounted onto a roof or ground without a lot of deviation in setup. They are normally created from stainless steel in a grid-like system of supports. Roof-mounted panels for smaller systems are the easiest to install, using tiny flush-mount brackets which raise the panels to the most excellent angle for solar collection.

Ground mounts, as the name implies, are solar panel mounts that are installed on the ground (as opposed to a pole mount or roof mount). They have supporting, changeable legs which allow you to optimize their upright orientation for solar exposure. Ground mounting systems usually entail lots of steel supports, concrete foundations, and galvanized footings, that can be troubling, when you are attempting to keep your system low cost. Ground mounted systems call for structural strength to avert load bearing failure.

Although module mounting systems are available for ground and roof installation, roof mount installation is the most popular and cost effective system. The roof mounted panels are attached to a mounting system usually consisting of an aluminum or steel support structure which attaches the panels to the roof.

The Down Low On Flush Mounts

Flush Mounts are economical and simple to install – these are ideal for single panel installations and smaller solar arrays. Flush mounts are put onto a level face such as the top of an RV, a roof, or the top of a boat and are not used for ground installations. These mounts act to separate the solar panel from the mounting surface and allow airflow to go under and cool the solar panel for smooth operation. Flush Mounts are normally used with small solar arrays on roof tops and RVs, because the structural design of a flush mount cannot support big solar panels.

Lots of options exist in the ever changing world of solar power technology. For all you could ever want to know about solar panels and wind generators visit where can I buy solar panels

Thermal solar power can be used in as many ways as you can think. Designs exist from heating up your hot water tanks, to industrial steam generation and everything in between. Many of these systems are attractive because of their low cost and simplicity.

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.

Other possibilities exist with pebble bed heat exchangers, which are designed to store excess thermal energy. These heat exchangers give our systems some operating flexibility. With this reservoir of heat, we can consider different applications for our thermal solar power system.

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 of a basic thermal solar power system will be somewhere between 100F and 200F. For high performance designs, up to 700F has been achieved for making high pressure steam. The exact temperatures we can obtain will depend entirely on the solar collector design and your system’s needs.

The solar collector is the most important component to a thermal solar power installation. A few different types include flat plate absorbers, evacuated tube absorbers, and parabolic trough concentrators. Their main purpose is to absorb solar radiation and generate heat for the system. With a good sized solar collector system, significant heat can be generated and distributed to multiple locations.

The circulating fluid flows through the solar collector to distribute the heat through your system. It should be selected based on the peak operating temperatures and equipment compatibility. Typical fluids are glycol, oil, and water. A low flow pumping system will be needed that is agreeable with your operating conditions.

Anyone seriously interested in energy independence should start with thermal solar power technology. The components are simple and inexpensive. If you could identify your climate as having reasonable amounts of Sun, then thermal solar power is encouraged to the fullest extent.

Thermal power systems are typically less expensive than solar power electricity, and can create household hot water and heat reliably. With the addition of pebble bed storage and higher operating temperatures, then the amount of potential uses suddenly becomes many. With the markets of sustainability re-growing their roots we expect to see a variety of new designs and installations in years to come.

As the Sun tracks its course through the seasons, the best solar panel operating angle will change. The more directly the solar panels can face the Sun, then the more beam radiation they will receive. Tracking systems, by adjusting this operating angle, help maximize this beam radiation received.

The amount of energy gained will depend on your location and the type of tracking system used. We looked up the solar energy tables for the state of Washington, and the difference between a fixed solar panel system and one with tracking was ~40% more in the summer months. The spring months showed a 25% increase, and winter about 10%.

The simplest type of tracking is a manually adjustable one axis system. The solar panels are installed in a south facing direction, with a rotating mechanism on their horizontal axis. One can make seasonal adjustments to maintain the best operating angle for that time of year. A simple system such as this can gain 20% better performance when compared to a fixed solar panel installation. The Rotek design we use is an example of one such system.

To further boost performance we can add a control system to our one axis tracking. This is called active solar tracking, where the solar panels automatically rotate throughout the day. These systems provide the largest gains, up to 50% in the summer months. Performance remains good throughout the year as well, so for a little more cost they are worth investigation.

Two axis tracking systems are the most complex and most accurate installations available. With these systems, your solar panels have additional flexibility on their vertical axis (East to West). These systems are the most exact when it comes to following the Sun.

Two axis systems are commonly used with concentrating solar collector designs. These types of collectors, like a magnifying glass, focus the rays of the Sun. Systems with these installations require the highest possible operating temperatures. Examples include thermal power stations, stirling engines, and pebble bed transfer systems.

Two axis tracking is not ideal with photovoltaic solar panels. In reviewing the energy tables, a two axis tracker will gain only 5% more energy over the one axis system. The greatest gains are realized, then, with the one axis system. For the cost, complexity, and convenience most users are better off with a one axis system.

Solar power systems are developed for two primary purposes: heat and electricity. Adding a solar tracking system to your design is useful for either case. When it comes to making electricity with solar panels, a solar power tracking system will increase the production of electrical energy. When it comes to acquiring and storing thermal heat, it will help your system obtain higher temperatures.

If you are serious about maximizing your solar power system, then you should be considering a tracking system. One axis systems are available that are effective, inexpensive, and easy to use. Two axis systems are more complex and normally used for high temperature systems. Either which way, a good tracking system will go a long way in getting the most out of your solar panels.

The term solar energy is used to describe electromagnetic radiation released by the sun. This radiation is extremely important to the Earths biosphere, and is the source of our existence. It is the catalyst for life as we know it on our planet.

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 is the primary element for Photosynthesis, the method by which plants make energy for growth. Plants in term provide us with food, wood, medicines, and more.

The Earths natural landscapes, they absorb solar energy and produce heat. It is the heat absorbed by mountains and plains that create local wind patterns. It is the heat absorbed by the oceans that creates the famous currents. Solar energy is responsible for thunderstorms, tornadoes, and hurricanes. It melts the mountain snows which form many of our rivers.

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.

Imagine if the Sun suddenly burned out, which scientists predict will happen someday. It is a reminder of the delicate balance to our existence, that Mother Nature will always hold the trump card to human prosperity. We should offer thanks for each and every day that we are blessed with the Sun.

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.

So if theres one thing for sure, its that solar energy is here to stay. We are solar energy, its the reason we can see, and reason we can eat. It is embedded in virtually everything that surrounds us. When the Sun goes, we will go with it.

The time has come now to discuss solar energy in different terms. Mankind has become clever these past few generations, and developed new methods to harness this energy. We now have ways to convert solar energy directly into electricity. And weve developed several new inventions for absorbing solar energy and making high temperature heat.

How practical is current technology for providing power to our homes? How much money will it cost, and how much will we save in the long run? What kind of new solar energy technologies are in development? We started out asking these same questions ourselves, and we are here as professionals from the Energy industry to present a few honest answers straight from the energy specialists.

To find out how to use solar energy as a budget source of power for your home get Walter Hull’s checklist on simple solar power from your yard.

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.

The basic answer is that certain materials are used to harness the sun’s energy and convert it into electricity which can be used to power our electronic devices. But it’s a bit more complex.

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.

It used to be that only space age technology, like satellites and space stations, used photovoltaic panels. They were reliable for their continuous solar energy conversion, and once in outer space, the sun’s radiation is at least 50% stronger than it is on our planet.

A good candidate for solar energy is someone living a mile or more from an electrical grid since it’s a lot more costly to install power transmission cables than it is to install a solar panel kit. If this is you, then maybe it’s time to consider solar energy as your main power source.

But still, the looming question is “how do solar panels work?” Well, solar energy is made up of two kinds of radiation. One is called “beam radiation”. Beam radiation can be visualized by imagining direct sunlight on your skin while at the beach on a clear, sunny day. These cloud-free days make a major contribution to solar energy being gathered by solar panels, but the solar panels need to be strategically placed to harness the most sunshine possible.

The other kind of radiation is “diffuse radiation”. This radiation is strewn all over the place (as its name suggests). On a cloudy day, it’s the primary radiation source for a solar panel. It’s the same thing if you’re relaxing under a shade tree diffuse radiation is what you’re going to get. Unfortunately diffuse radiation isn’t very strong and relying on it alone for solar energy isn’t practical.

For solar panels to work efficiently, a sunny location is mandatory. Beam radiation is the most effective since it’s the strongest. Most of Western America qualifies as a good locale for beam radiation those states are good candidates for the use of solar energy, but northern climates and coastal states are usually quite cloud-laden and sadly, not worthy of 100% solar-reliance.

Solar panels can be built to meet special needs. 12 volt, 24 volt and 48 volt DC systems are the most popular. 12 volt solar panels can survive for over 20 years and are about 12-14% efficient.

One reason that solar power is still considered an “alternative energy source” is due to the high cost of production. The silicon semi-conductor materials are costly, but new materials are being experimented with and they’re geared towards lowering the price of producing solar panels. This would make solar power more accessible to the “average Joe”, and in turn helping save our atmosphere.

Soon enough, solar energy won’t be considered “alternative” anymore. You want to consider certain things if you’re planning on converting to solar power before making a decision, but it’s a step in the right direction for the environment. The benefits outweigh the cost when it comes to our planet’s health. Energy independence has become a common goal for many, and if you want to use solar as just a back up plan, then the choice is practically already made for you. The planet will benefit immensely once solar energy is accessible to everyone.

To find out more on how do solar panels work check out some more information here.

Solar panels are often mounted on roof tops, because the roof structure is strong and already exists. If your roof is sloped in the right direction, then how convenient this is. And convenience is a legitimate player in any decision making process.

The roof mount method is not perfect, however. For those of us who want the best performance from our solar panels, or who live in northern climates (as do the writers), there are some alternatives to think about.

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.

Those of us with this problem, then, might consider other ways to mount our solar panels. We have come up with one such design called the Rotek system. It was developed on homesteads in the mountains of Idaho and Colorado, where we receive plenty of sun and plenty of snow.

With this design, the solar panels are installed remotely rather than on the roof. This provides additional space beneath the panels which Rotek puts to use. The panels can be rotated to almost any angle with a simple move. This feature is good for making seasonal adjustments based on the Sun.

A second advantage comes in Winter when the solar panels can be rotated toward the ground, and operated at steeply sloped or negative tilt. This prevents the buildup of snow on the photovoltaic surface. It is also good for periodic glass cleaning, maintenance, or for dumping a load of snow if the panels were left up in a storm.

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.

A second big issue with solar panels is their operating temperature. The cooler the panels, the more we maximize their discharge current. Roof mounted solar panels acquire much more heat, and the amount of energy lost at these higher temperatures can be as high as 20%.

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.

Sooner or later the time will come to install your solar panels. The roof installed units will make a lot of sense, but those who want improved performance and adjustability should consider other options. The Rotek system is one such option, easy to install and simple to use without the extravagant cost.

Walter Hull is a recognized expert in solar energy power systems. For a limited time you can get his free checklist to solar energy from your own land.

It is necessary to study some factors before to buy or to build solar panels. For exemple, the quality of the solar panels, the cost and the climatic conditions.

There are three ways of building or acquiring solar panels namely:

1. SELF-MADE: Act of constructing a solar panel by you using a well detailed manual as a guide. You may ask what a well-detailed guide is.

These guides have pictures and diagrams that show how to assemble the panels either in parallel or in series, or the angle of titling of panels depending the required voltage. The manual will inform you where to get the cheapest panel for your installation. You can have one in less than $200.

2. FROM A TRUSTED BRAND: You can buy solar panels from a commercial shop with all guarantees. But the cost is really high.

3. FAIRLY USED SOLAR PANELS: It is difficult to find used solar panels. But you can certainly choose this option to save money. Due some reasons such as a person trying to increase the quantity of voltage or relocating to a new place, a decision to dispose the existing one can be taken in this case you can take advantage and buy. The life of solar panels can be up to 30 years.

Obviously, the benefit of building one by yourself is huge both financially and environmentally.

It will only cost you just the money to acquire such guide and less than $200 to make a residential solar energy. Invariably, making it an easy task of recouping your initial investment and continue enjoying the subsequent years of its use without monthly payment of government tax. In addition, making one your self improves your technical know how, which you can use in making money by building for others without much hassles.

If you really plan to build your solar panels, you must know that you will need time to dedicate. It takes longer time than if you buy a new one. On the other hand, the commercial panels are quite expensive.

In summary, the best form of learning is learning through an experience teacher, therefore using a tested and trusted manual in making cheap solar panel remains imperative for your success.
