Electricity is generated from solar panel using certain device called photovoltaic cells or solar cells, the photovoltaic cells converts' solar energy from the sun to electricity. Solar energy is much cheaper and reliable than it used to be some years ago, because these devices have been developing rapidly. You could decide to install solar panels as a supplementary source of energy to reduce your monthly bills on electricity.

Here are some reasons why you must consider installing solar panels for your homes:

- Clean. Solar power is definitely the cleanest source of energy. There is no burning of coals or other fossil fuels and at the time it doesn't produce greenhouse gases. So, it really doesn't have any harmful effect on the environment.

- Plentiful. There is absolutely no limit to solar power. There is more than enough to go round for everyone; there would never be a time when solar energy would be exhausted. As a matter of fact, the amount of solar energy reaching the earth each minute is more than the energy consumed yearly by the entire planet.

- Solar panels are easy to install and use. You can install solar panels for as little as $200 and they are relatively inexpensive to maintain once they are installed. Also, installing solar panel is easy, it's something you can do by yourself, and all you need is a step by step guide.

After all has been said, you will clearly agree that energy from the sun or solar power is without doubt a great way to reduce dependence on fossil fuels as well as cut back on your cost of electricity. So, I wonder why anyone would ignore the use of solar energy in their homes.

Premade home solar panels can be quite expensive. But why pay for them, if you can have a DIY system for less than $200? See this guide to making a low cost home solar power system using readily available components.

Wind Turbine Generators.

Bolstered by available federal stimulus dollars, we are seeing a virtual modern day 'land-rush'. In the words of one industry leader, 'if there is a site that has a viable wind profile, access to network connections, and access for delivery of materials, and we don't develop it, some one else will.'

This head long rush to install more and more wind turbines has outstripped the usual developmental learning curve, where new technologies mature by a process of trial and error, resulting in defining equipment suited for the job at hand.

The added economic pressure of today's market has made an already competitive market even more demanding. This has, in the view of many industry insiders, resulted in  purchasing decisions for equipment based largely on the lowest initial cost solutions and not  solutions that will provide the best choice in terms of total cost of ownership, network stability, less down time and lost revenue from high maintenance issues. This is nowhere as apparent as in the case of Wind Turbine Generator (WTG) transformers.

Historically this WTG transformer function has been handled by conventional, 'off the shelf' distribution transformers, but the relatively large numbers of recent failures would strongly suggest that WTG transformer designs need to be made substantially more robust. The practice of using  conventional 'off the shelf' distribution transformers as a low cost solution is folly. In some cases site operators are maintaining a quantity of spare transformers to combat the frequent outages caused by standard distribution transformers being used where they are not suitable.

The role of the Wind Turbine Generator (WTG) transformer in this process is critical and, as such, its design needs to be carefully and thoughtfully analyzed and reevaluated.

Transformer Loading:
Wind turbine output voltages range from 480 volts to 690 volts. The turbine output is transformed, by the WTG transformer, to a collector voltage of 13,800 to 46,000 volts.  The turbines are highly dependant upon local climatic conditions; and this can result in yearly average load factors as low as 35%. The relatively light loading of WTG transformer has a favorable effect on insulation life but introduces two unique and functionally significant problems.

The first problem is when lightly loaded or idle, the core losses become a more significant economic factor while the coil or winding losses become less significant.  Typically used  price evaluation formula do not apply to this scenario.  NEMA TP1 and DOE efficiencies are not modeled  for the operational scenario where average loading is near 30-35% and, consequently, should be cautiously applied when calculating the total cost of ownership for WTG transformers.

The second problem is that the WTG transformer is subjected to frequent  thermal cycling as a function of varying turbine loads. This causes repeated thermal stress on the winding, clamping structure, seals and gaskets. Repeated thermal cycling causes nitrogen gas to be absorbed into the hot oil and then released as the oil cools, forming bubbles within the oil which can migrate into the insulation and windings to create hot spots and partial discharges  which can damage insulation. The thermal cycling can also cause accelerated aging of internal and external electrical connections.

Harmonics and Non-Sinusoidal loads:
WTG transformers are switched with solid state controls to limit the inrush currents.  While potentially aiding in the initial energization, these same electronic controls contribute damaging harmonic voltages that, when coupled with the non-sinusoidal wave forms from the turbines, cannot be ignored from a heating point of view. When a rectifier/chopper system is used, the WTG transformer must be designed for harmonics similar to rectifier transformers, taking the additional loading into consideration as well as providing electrostatic shields  to prevent the transfer of harmonic frequencies between the primary and secondary windings.

Transformer sizing and voltage variation:
WTG transformers are designed such that the voltage is matched to the wind turbine's output voltage exactly. There is no 'designed in' over-voltage capacity to overcome voltage fluctuations which are a frequent problem with wind turbines. At the same time, the generator output current is monitored at millisecond intervals and the operational limits allow up to 5% over-current for 10 seconds before it is taken off the system.  Therefore, the WTG transformer  is designed to match the generator output with no overload sizing, and  the WTG transformer design must be uniquely robust to function without it.

Requirement to withstand Fault Currents:
Typically, conventional distribution transformers, power transformers, and other types of step-up transformers will 'drop out' when subjected to a fault. Once the fault has cleared, the distribution transformer is brought back on-line. Wind turbine generators, on the other hand, in order to maintain network stability are not allowed to disconnect from the system due to network disturbances except within certain guidelines developed for generating plants.  The length of time the generator is required to stay on line can vary. During this time the generator will continue to deliver an abnormally low voltage to the WTG  transformer. Therefore, during faults, the transformer may be required to carry as low as 15% rated voltage for a few cycles and then ramp back up to full volts a few seconds after fault clearing. The WTG transformer must be uniquely designed with enough 'ruggedness' to withstand full short circuit current during the initial few cycles when the maximum mechanical forces are exerted upon the WTG transformer windings.

Conclusions:
The role of WTG transformers in today's wind generation scheme is unique; it's design must be equally unique and robust. Don't trade long term reliability and lower total cost of ownership for low initial cost.

Wind Turbine Generators.

Historical background in brief

People have been using wind power from the time immemorial.  
Originally they learnt to transform kinetic energy of wind stream into mechanical one. There appeared lots of different wind mills making men’s life much easier in those times.

An idea of a wind turbine for electric power generation using wind power started up around 100 years ago.

Inventors created wide range of various types of wind power generator designs:
- by axis (horizontal, vertical, inclined); 
- by number of blades (one, two, three and more);
- by capacity (from tens W to several MW);
- by blade design, by generator design etc.

But in an attempt to raise WTG’s capacity inventors faced new problems:

1. Mechanical properties of materials modern wind generators are made of become serious constraints due to the generators’ size and dynamic loads they bear. Further expanding capacity (size) of wind generators calls for application of the latest which means more expensive materials which is reflected on the rise of prices of generated power that are rather high even without that.
2. Wind generators of higher capacity require higher wind speeds. Nowadays it becomes more and more difficult to find areas for construction of wind farms but people require more and more power.

Today wind energy market grows up to 30% annually. But with wind power generation enthusiasts along there lately appear more and more skeptics. Wind power generation being clean and using renewable sources has number of substantial disadvantages: low quality of generated power, TV and radio signals interference, bad sound influence on fauna and need in additional reserve power generating capacities of traditional design etc.

More and more people being worried about negative trends in wind energy generation reasonably ask such questions as: What are the prospects of wind power generation? Will wind power generation take economically significant place in world economy? Will the investments in wind power generation be fruitful etc.?

World oil and gas market situation stimulates development of power generation using renewable sources. High price and low quality of such electric power does not make estimates of wind energy generation prospects more optimistic.

People need new reliable sources of electric power meeting following requirements of today’s life:
1. Low price of generated power
2. High quality of generated power
3. Power output should satisfy constantly growing demand
4. Clean power generation
One of the alternative power generation solutions meeting most of the requirements mentioned above is presented below.

Everything new is long forgotten old

Wind energy generation is fundamentally based on two elements: energy source (wind) and energy receiver (wind turbine generator).

Since first steps in wind power development and until now inventors have been improving energy receiver but energy source (wind) has been considered to be a gift of nature that is beyond any control.

In many ways it reflected in various disadvantages of modern wind power generation.

In technical system “wind – wind generator” both elements are equally important. 
Only control over all elements of a system allows reaching highest working efficiency. 
Improving energy receiver they dropped an idea of controlling wind for no need. But in vain!

Level of modern technical development allows arrangement of quite an effective control over such systems.

But wind power generation went the other way. At present all wind generators operate on the basis of the same principal: collecting energy of incoming air flow.

We decided to develop a brand new technical system which could allow controlling both energy source as well as energy receiver. Using men’s experience and knowledge in construction and operation of wind generators we can sufficiently increase their working efficiency by controlling of air flow parameters (energy source).

One of the results of our long year researches and tests is a tower wind turbine. It gives a possibility more or less to control all the elements of the system “wind – wind generator”.

Tower wind turbine consists of the following main elements: energy collecting device, generator, energy concentration device and control system.

Energy collecting device is designed as a vertical cylinder the walls of which are framed of profiles making end-to-end channels connecting outer side of the cylinder with its inner vertical channel (input convergent channels). Their aim is to “catch” incoming air flow and turn it vertically up along the vertical axis of the unit and to send it to generator blades.

Generator with blades is places inside the energy concentrating apparatus. Generator transforms kinetic energy of wind into electrical one.

Energy concentrating device is contractually designed as a vertical hollow tower inside dimensions of which converge in the central part where the generator is placed. Inner part of the tower is continuation of the vertical inner channel of the energy collecting device. Such design allows concentration of kinetic energy of wind on generator blades.

Control system (is not shown in the picture) provides timely opening of convergent channels of the tower from the side of the incoming wind and closing of all the other convergent channels.

What are principal differences between tower wind turbine and conventional wind generators, transforming energy of incoming air flow?

1. It allows controlling wind energy concentrating on generator blades. 
2. Rotor blades do not need to be “tuned” to wind. Vertical axis generator is fixed in the upper part of the unit. Wind is “tuned” to the generator itself owing to design of the energy collecting device.
3. Speed of wind rises significantly when it reaches generator blades. Design of the energy concentrating device allows raising wind speed in the inner vertical channel of the unit increasing its capacity accordingly.

Experimental tests of the unit models in aerodynamic tunnel showed growth of power output of the generator placed inside the tower more than 4 times, and at low wind speeds – more than 10 times.

To prove received results a 100:1 scale production prototype was constructed. Diagram of comparative tests is similar to laboratory tests diagram.

Analysis of received results shows significant efficiency growth of the generator placed inside the concentrating tower in comparison with wind generators of conventional design: 
- Wind initial velocity is 2 times lower;
- Rated wind speed is 2 times lower;
- Utilization factor of installed equipment can reach 0,6…0,7 (was calculated) ;
- Power output is 2-3 times higher;
- 5 times more energy is collected from wind stream area unit at all wind speed ranges, at low speeds – more than 10 times;
- Area of allotted land per unit of rated capacity of the TWT is the lowest among all types of generation.

Tower wind turbine concentrates wind energy on generator blades like a lens collecting sun light into the focus.

Design features of the TWT allow elimination of various disadvantages of conventional wind generators:
1. Noises and radiation harmful for people that can appear during operation of the generator of the TWT do not leave the tower as generator and blades are placed inside of it. Modern materials allow reduction and absorption of harmful noises and vibrations. For the same reason generator and blades of the TWT do not interfere TV and radio signals.  
2. TWT can not cause any injuries for birds. To prevent birds from getting onto generator blades one may place protective nets at the entry to the convergent channels. To avoid birds clashing into the TWT at night its outer surface is lighted. It could also improve tower’s appearance.

Future Outlook

Technical characteristics of the TWT surpass all the modern convention wind turbine generators using incoming air flow.

Tower wind turbine can be a worthy substitute for conventional wind turbine generators:
- TWT can work at low wind speeds. 
- TWT allows reaching larger power output. 
- TWT’s effectiveness is in no way lower than that of conventional power stations using carbon fuel such as: gas, coal, black and crude oil and its ecological cleanness has no analogues.  
- TWT becomes very effective in areas with low wind speeds. 
- Area of allotted land per unit of rated capacity of the TWT is the lowest among all types of generation
- Due to its compactness TWT can become an autonomous self-sufficient power source.  

Tower wind turbines today are world wind power generation of tomorrow: low production cost and high quality of ecologically clean energy.

Wind Turbine Generators.

Alternative energy wind power clearly has a very significant role in order to play in developing the sustainable conductivity future we so badly want. Wind power has attracted some negative press due in order to the impact on the environment and that it may contain.

Wind turbine generator designs contain historically utilised a modular formation with a generator, gearbox plus main shaft.

Wind Turbine Generator Total Height: Horizontal Axis Wind Turbine Rotors: The area between the ground as well as the highest point of the wind turbine generator, in addition to the length by what the rotor wind vanes or blades mounted on a horizontal axis wind turbine rotor exceeds the height of a wind turbine generator.

Wind turbine generator systems incorporating a multi-speed pole amplitude modulated type generator electric machine allowing economical activity at consecutive speeds in a ratio preferably less than 2:1.

The New York Power Authority (NYPA) released a request for proposals (RFP) on December 1 for the development of offshore wind power projects in the New York State waters of Lake Erie in addition to Lake Ontario.

The environmental impact of resource depletion calls for moreover very smart ways of convert renewable sources into useful generated power. A class 3 wind resource, what is not unorthodox throughout much of the United States, is the minimum level suitable for wind most wind turbine applications.

The LMP/FTR system has deprived [public power entities] of their ability to plan with any certainty for new long-term production resources that would require transmission service, e. g. , development of or participation in a new producing resource (including environmentally desirable resources such as wind generation), or execution of long-term power contribute contracts with suppliers that require the buyer in order to assume the risk of transmission service.

On the 18th January thirty school children descended on the Houses of Parliament prior to showcase triumphant examples of renewable energy wind turbines.

moreover recently continuously variable or multi-speed wind turbine generators involve been mentioned. For example, variable speed production may be achieved through apply of a variable frequency alternating current generator followed by a rectifier plus an inverter.

With the wind turbine generator of the present invention, an in-nacelle cooling air outlet that opens in the direction of the anemoscope/anemometer is provided at the top of the nacelle, plus the air outlet has a blowing-direction changing device for the cooling air.

Alternative energy wind power clearly has a greatly significant role to play in developing the sustainable conductivity future we so badly demand. Wind power has attracted some negative press due to the impact on the environment what it may involve.

Wind Turbine Generators.

More and more one hears of the environmental issues that have risen as well as the ways in which to help improve the environment. Many people are coming to appreciate the fact that we are destroying our world, and that we must take steps to improve the environment and environmental threats that surround us.

Wind turbines collect energy from natural air flow. When this happens, due to the function of wind turbines, the air slows down and then spreads, diverting it around the wind turbine device or devices.

Here is a condensed idea of how the wind turbine works:

1. The Betz Limit

o Betz Law or, the Betz Limit determined that the use of a wind turbine can generate almost fifty-nine percent of the energy that would flow straight through the cross section in the construction of a turbine.

o No matter what kind of wind turbine or wind turbines one has, regardless of design, the Betz Limit applies.

o Albert Betz, a physicist from Germany, discovered this fact: that a wind turbine works (almost universally) as an incredibly effective kind of energy net for wind power.

o Albert Betz made this discovery in the year 1919.

2. The Unpredictability of Windy Weather

o Because windiness varies no matter where you live, it is impossible to predict exactly how much wind can be generated over a significant period of time such as the yield per year.

o In addition, different places have different probabilities of amounts of wind distribution.

o The most frequently used piece of equipment used to determine the wind speed distribution is a two ? parameter Weibull distribution monitor.

o This piece of equipment is used to determine what have been termed 'distribution shapes? from Gaussian to exponential.

For example: The Rayleigh model

This is a specific form of the Weilbull distribution function. In such a case, the distribution shape should be a parameter that equals two. Imitating or mirroring the distribution shapes, the Rayleigh model of the exact hourly wind speeds and patterns of a particular area.

3. Higher Wind Speed

o Because in certain places there is so much wind power to draw from, a lot of the wind in such places comes in gusts or short bursts.

o Here's a good example:

When comparing the size of fueled power plants to the potential power of wind turbine farms, one will find that 10000 kW of wind turbine power is theoretically enough to produce as much power and energy as approximately one half of that, in power generation that is coal ? fired.

o Despite unpredictability, the annual reports of wind turbine energy output usually vary by only a few points from year to year.

4. Turbine Sitting ? when location is key:

o The general rule is that when a location has an average wind speed of ten miles per hour it is a perfect location for wind generators.

o Meteorology plays a very important part in the determination of exactly where to set up a wind farm or any other kind of wind turbine generator.

o Ideally, one wants a location with a constant stream of wind as opposed to turbulent, gusty high mph winds.

o The wind will virtually always blow faster at higher altitudes because of reduced drag from the sea or land, as well as the subsequently lower amounts of viscosity in the wind current.

o Very flat lands with smooth average speed winds are great locations for wind turbines as well.

5. Wind Parks and / or wind Farms of have many wind power turbines installed.

o Utility-scale wind turbine generators have to have limits for the operating minimum.

o This can prevent the application of a wind power generation system in especially cold areas

o There are, however, many experiments in the making. There are internal heaters, heating lubricants, and minimum temperature monitors to consider in the installation and use of wind turbines.

More and more one hears of the environmental issues that have risen as well as the ways in which to help improve the environment. Many people are coming to appreciate the fact that we are destroying our world, and that we must take steps to improve the environment and environmental threats that surround us.

Professionals have estimated that 1% to 3% of the Sun's energy, the energy that hits the earth, transforms into wind energy. To give you an idea of how much energy this is, in simple terms: it is about fifty to one-hundred times the amount of energy that is produced by plant life and biomass over the entire earth.
