5 Things You Should Know Before Buying a Wind Inverter

With the deteriorating health of our planet there is an urgent need to take actions to prevent further damage to its health. Installing a wind power system is one of the best ways by which people can contribute to limit the damage being done to our environment by various human activities. Wind inverter is one of the integral components of the system. One should keep a number of factors in mind while buying a wind inverter.

Size

Different homes have different power needs. Therefore you should keep the power consumption in your house in mind while choosing the size of your wind inverter in Dublin. Those who want to run a computer, 2 light bulbs (of 60 Watt) and a radio may consider buying a 500 W inverter. It is advised to buy a larger one than needed so that there is no difficulty in adding one or two appliances to the power system.

Type

A large number of inverters are developed from motor drives. This type of appliances is not much efficient. It is recommended to invest in inverters that are specially designed to convert DC power into grid voltage. They are among the most efficient types.

IP Rating

Inverters based on motor drives have a lower IP rating and therefore they need open ventilation environment for operation. Therefore this type of power systems is not suitable for places with lot of damp, dust and dirt. A high IP rated inverter is more suitable for outdoor locations where dust and dirt are major factors.

Starting Voltage

This is another vital factor that a buyer should bear in mind while buying a wind inverter in Dublin. Some inverters have starting voltage of more than 200V DC so they fail to receive and store energy when the turbine is spinning at a slow speed. So opting for an appliance with lower starting voltage would be a better option.

Vendor

Apart from the technical factors one should also be particular about the vendor while buying wind inverter. The seller should be reputed and should have some years of experience in the market. The best way to learn about a vendor is to check their websites and other related websites and see what their customers have to say about their products.

Keep the above factors in mind and you can make a smarter decision while buying a wind inverter.

Solar energy is a wonderful alternative energy that could be used for homes. If you are planning to buy a solar home inverter system then you should keep certain things in mind to get the right device.

Capacity and Output

Capacity of an inverter is the maximum load that could be connected with the device. The capacity of the device comes in Kilowatt. An inverter of 1 or 2 KW is sufficient for a home. You can also opt for a larger capacity if the budget permits. One should also consider the output waveform of the inverter before picking a product. A sine waveform is considered a better option that other types.

Metering

A number of measuring devices are integrated in the inverter that gives the status of battery charging, mains on/off indications, battery low etc. A good solar Inverter has all the necessary meters to suggest the status of different controls.

Programmable Controls

Most modern solar inverters for home come with programmable energy control system. This helps in operating the device in an easier way. One has the option of deciding what amount of energy should be used when.

Do you have enough space?

Though it isn’t directly related to the solar inverter system, it is one of the most important aspects that you should keep in mind if you want to install a solar power system. It is important to be sure of the fact that there is enough space in your house both for installing the solar panels outdoor and for accommodating the inverter system indoor. Depending on the space available you should consider what type of devices to buy.

Servicing and maintenance

If you are planning to buy solar inverter in Dublin, you should make sure the vendor or the manufacture has good after sales service in the city.

Does Wind Turbine Generate Electricity?

Wind turbines have been used for centuries to generate electricity that can be used for various applications in households as well as for commercial uses. Wind turbines use the kinetic energy of the wind and convert it into electrical energy. Large wind turbines have propellers connected to generators, which when moved by the wind generates electricity. Individual wind turbines can also be used for producing electricity on small scale to support a single home. Whereas large scale electrical energy can be produced with the help of a group of wind turbines, known as wind park or wind farm.

The blowing wind moves the blades while passing through the turbines and this result in spinning of the shaft. Two types of wind turbines can be used to produce electricity namely, Vertical Axis Wind Turbines (VAWT) and Horizontal Axis Wind Turbines (HAWT). The most commonly used wind turbines are the HAWTs and they have fan-style blades, whereas the VAWTs have egg-beater style blades.

How is electricity produced in Wind Turbines?

Before you start looking up for wind turbines for sale, you need to understand the working principle of turbines, so that you get the best one for your use. Here is how electricity is produced by wind turbines:

    • Each wind turbine is fitted with box on top which is known as nacelle. Three blades are attached to this nacelle and they are also connected to a rotor. The anemometer on the nacelle measures the wind speed and wind direction.
    • The nacelle is turned towards the wind and the kinetic energy of wind turns the blades around the rotor.
    • The rotor is connected to the shaft that rotates inside generator housing. This results in the magnetic rotor to spin inside loops of copper wire. This activates the electrons inside the copper wire to flow, producing electrical energy.
    • Thus electricity is then routed to the underground cable through large cables that are attached to the nacelle.

At wind parks, electricity from various turbines is directed to the substation where a step-up transformer increases the electrical output.

How are the blades connected to the shaft?

The blades turned by the wind results in formation of electricity and there are two ways in which the blades are designed, namely lift type and drag type.

1. Lift Type: The most commonly used HAWT use this design. The air blows across both sides of the blade which means that the air takes longer to travel across the edge. As a result of this high pressure is created on the tail edge and low pressure is created on the leading edge. This pressure difference make the blades to move at a high rotational speed which is requires to generate electricity.

2. Drag Type: The force of wind is used to move the blades and they have higher torque compared to lift designs but with lower rotation speed. This type of design cannot be used for large scale energy generation since it has low rotating speed.

Why Wind Turbine Blades Are Twisted

It is essential to produce green energy to save the earth and create a sustainable environment. The most commonly used renewable source of energy to produce electricity is Wind that can be found in ample amounts all the time. But at times it becomes very unreliable and unpredictable because of the fact that it constantly changes its strength and direction.

Why Wind Turbine are Made Tall?

To utilize it wind power and produce maximum amount of energy, wind turbines are made tall and large. For wind turbines to be functional they need to be designed and engineered very well and this is the reason why they are so expensive. Most of the modern day wind turbines are provided with two to three blade propellers that rotate around a horizontal axis. These wind turbine blades convert the wind energy into shaft power known as Torque, which is produced as a result of the deceleration of wind blowing over the wind turbine blades, with help of various techniques.

So Why Are The Wind Turbine Blades Twisted Or Curved?

A lifting force is generated due to the curved shape of the blades just as in case of an aeroplane wing. A low air pressure is created on the side with most curve, while the high pressure created beneath pushes the other side of blade aerofoil. This results in generation of a lift force that is perpendicular to the air flow direction. The rotor blade also needs to be designed appropriately to generate the right amount of rotor blade thrust and lift to produce the exact amount of deceleration of air.

What is TSR and what factor it Depends?

The wind turbine blades have to rotate at an optimal speed to extract the maximum amount of energy. If it rotates slowly, it won’t be able to produce enough energy and if it rotates quickly it will create excess drag. The tip speed ratio (TSR) is the ratio between the speeds of the rotor tip to that of the wind speed. The TSR depends on the number of turbine blades, rotor blade shape and the shape of the wind turbine blades.

Wind Turbine Generate Power at Low Costs

The wind turbine blade cost is higher since it needs to be designed in a manner that it maximizes the power generation at low costs. The turbine blade manufacturers constantly work towards improving the design of the blades so that they can be quieter, compact and capable of generating maximum power from minimum wind.

Twisting the blades of the wind turbine makes it capable of capturing 5-10% more energy from wind and functions efficiently in places that have lower wind speeds.

Top 4 Myths About Renewable Energy

There is much debate about the issue of Renewable energy –vs- Fossil Fuel – particularly for those skeptical about the risks of climate change resulting from man-made greenhouse gasses.

This has given rise to many myths about renewable energy.

Find these myths being busted below:

 

MYTH 1- Renewable Energy is Expensive:

In the case of solar and wind energy, all of the costs are in producing the equipment (and maintaining it in the case of wind). Once built there is no fuel.

More importantly, there are no hidden costs resulting from pollution. Electricity produced from coal is particularly polluting (and Ireland still uses the Moneypoint coal-fired station).

If (as we do) you believe that climate change is, or will be, caused by man-made greenhouse gases, the long term costs of energy from fossil fuels is truly enormous.

 

MYTH 2- Renewable Energy do not deliver 24*7 :

It is widely believed that renewable energy production is dependent on weather conditions and its production can vary depending on cases such as wind speed, solar power etc. But the reality is that in most cases, various forms of renewable energy are integrated and thus the variability can be adjusted accordingly. This is increasingly true if you add more solar power to the Irish grid where it complements wind and hydro power especially well, but with large grid interconnection, there is always a mix of sources available.

 

MYTH 3- Renewable Energy is Not a Reality Yet:

Though renewable energy is working in a full fledged manner in many countries, some refuse to consider it as anything more than fiction. Some data that can bust this myth:

Germany gets its 25% of electricity from renewable energy sources, which aims to power the country almost entirely on renewable sources by 2050.

Spain, Portugal, Iceland, Denmark are some of the other countries which are working towards attaining 100% renewable energy.

 

MYTH 4 – It takes more carbon or energy to make a solar panel or wind turbine than it produces in its lifetime

This simply is not true. Firstly, if that were true, the cost of the energy would be reflected in the product cost, and it could never repay its cost in its lifetime.

If you study the carbon emissions caused by the production of steel, aluminum, copper and other component parts of both wind and solar, you will find that the carbon emissions and fuel emissions saved by the product make up for its production within about 1 year.

 

Conclusion:

The internet is littered with misinformation, often given by well-intentioned people. But proper research will show that renewable energy is the only long-term way we can maintain our lifestyles. And even if you do not believe in climate change resulting from greenhouse gases, we can all understand that oil and gas are finite resources which cannot possibly power civilization forever.

Solar Inverters – a brief overview

Solar panels produce DC (direct current) when the silicon junction is exposed to light. A solar inverter converts this direct current to alternating current (AC power) which must be compatible with the grid so that domestic appliances can use the power.

 

Solar inverters become popular and are now mass produced as a result of the solar revolution taking place throughout the developed world. They are:

  • Efficient – most inverters convert power at efficiency levels above 95%.
  • Economical – mass production has brought the price of inverters down to about €300 for smaller models.
  • Environmentally Friendly – made from materials which can be recycled at end of life, and with no moving parts, to ensure longevity of the units themselves.
  • Very low maintenance – after the cost of initial installation, solar inverters are virtually maintenance free and durable.

 

  1. A Stand Alone Solar Inverter – It pulls direct current power from batteries charged by various resources such as diesel generators, solar panels and wind turbines. These inverters convert battery direct current into the alternating current (AC) to create a mini-grid when there is no grid present. These are usually used in homes or industrial buildings as a power backup and or for operating small appliances depending upon the wattage. They are also commonly known as off-grid inverters”

 

  1. A Grid Tie Solar Inverter – converts power from solar panels into AC power for transmission on the grid. This type of inverter must include a number of protections known as “anti islandint” to ensure that it does not send power to the grid during power cuts. This is essential for the safety of ESB staff working on power lines during an outage. Unfortunately this means that the panels cannot provide electricity during power cuts. In Ireland, inverter must meet EN50438 standards with some unique Irish variants.

 

How Does a Solar Inverter Work?

The main components of a solar power system are, solar panels to produce the power, an inverter to convert the power to AC and inject the power into the grid, Isolators to ensure that the system can be disconnected, and an MCB (trip switch). The electricity from the inverter flows into the household grid. From there it can either be used by appliances within the house, or if there is a surplus, it will be exported via a meter to the electricity mains grid.

 

The inverter is the “heart” of any solar power system. It not only converts the direct current generated by the solar panels to alternating current, but it also uses MPPT (Maximum Power Point Tracking) to ensure that the panel is kept at an optimum voltage to produce the maximum amount of electricity.

Advantages of Renewable Energy

Renewable energy is critical to the survival of our lifestyle – for two reasons; the fact that fossil fuels will eventually run out, and the need to reduce our emissions of climate change gasses.

There are various sources of renewable energy, each with its own advantage, but they all are clean and, provide jobs and boost the economy.

Solar photovoltaic in particular though is affordable at a domestic or household scale, and requires no maintenance.

 

Clean:

Solar photovoltaic panels produce electricity reliably for over 25 years, and many panels made over 40 years ago are still working. Solar energy complements wind turbines because usually in Ireland, when you have less wind, you have more sunlight. There is a seasonal balance when you combine wind and solar. Solar panels also produce all of their power during the daytime when demand from industry is highest.

 

Affordable:

According to a report by Sustainable Energy Authority of Ireland (SEAI), Ireland has saved more than €1bn from fossil fuel imports as a result of the roll-out of renewable energies, and has cut down on CO2 emissions by 12m tonnes. In the long term, as oil and gas prices rise, this will stabilize the cost of electricity production.

 

Domestic:

If you use the electricity you generate, you save the full retail price of electricity, and you future proof yourself from future price rises.

Depending on your location, a 4kWp system can generate between 3,400 kilowatt hours and 4,000 kilowatt hours of electricity a year – roughly equivalent to a typical household’s electricity needs.

 

Renewable/ Infinite:

 Renewable energy or renewable power, as the name suggests is such a source of power that can replenish itself over and over again. This is not true of oil and gas, all of which will eventually run out. Why should we wait to make the switch?

 

Less maintenance:

Renewable energy projects based on solar photovoltaic panels require less maintenance compared to traditional generators. And with evolving battery technology, it is widely believed that self-consumption will increasingly become widespread.

 

Jobs and the Economy:

The Irish Wind Energy Association in 2012, claimed that the renewable energy sector could compete with Ireland’s financial, electronics and pharmaceuticals sectors and could expect generation of 18,000 new jobs in the coming eight years.

 

The group also claimed that if the targets are met then there could be investment of more than €18bn into the Irish economy.

This sector can grow beyond those targets if solar is combined with wind. The advantages of solar are that the investment and profit can be in the hands of local householders. Any house can benefit from the addition of solar panels to reduce reliance on imported oil and gas.

History of Wind Energy

  • The concept of “Windmill” has been prevalent throughout the world for ages. From as early as 200 BC simple windmills were used in China for pumping water. The Persians built windmills in the 7th century AD for milling and irrigation.
  • It was by the help of this wind energy that ancient explorers took to the world and explored the unknown. The ability to harvest winds in sails determined a country’s ability to be a superpower. .
  • By the 18th and 19th century, windmill had become one of the trademarks of Europe which was mainly used for milling of grain and water pumping.
  • The first wind powered electricity was produced by a machine built by Charles F. Brush in Cleveland, Ohio in 1888.
  • The first vertical axis wind turbine which is also known as the Darrieus turbine, was invented by George Darrieus in 1920s. The Darrieus turbine windmill is also known as the eggbeater windmill since with its two or three blades it looked like an eggbeater.
  • The world’s first megawatt wind turbine which weighed 240 tons was built and connected to the power grid in Castleton, Vermont.
  • The popularity of wind energy has always been directly proportional to the supply and cost of fossil fuels. During the World War II when the price of fuel came down, the wind energy lost its popularity but again in 1970s when the price of oil skyrocketed , the interest and demand of wind generated power rose to a huge extent.
  • The demand and generation of wind energy increased more than fourfold between 2000 and 2006.
  • When it comes to wind energy capacity, Germany tops the list followed by Spain, the United States, India, and Denmark. It is also being estimated by the experts that if this pace continues, by 2050 one third of the world’s total electricity would be created by the wind energy.

5 Important Facts About Wind Power

It is being estimated by the experts across the world that by 2050 one third of the world’s electricity would be generated by wind power. This power generating source has many surprising aspects which everybody should know:

Use of wind power reduces Carbon dioxide content:

Use of wind energy reduces carbon dioxide production, and also, once constructed, uses no water for its generation and saves huge amounts of water. As per the report by National Renewable Energy Laboratory of US, every year 1MW of wind energy can reduce almost 2,600 tons of carbon dioxide production. The report also says that 1 MW of wind energy can save 1,293 million gallons of water!

The demand for Wind Energy is skyrocketing at an unbelievable rate:

The production of wind energy increased almost fourfold between 2000 and 2006 when the cost of fuel went up because of the unrest in oil producing areas of the world. Though production of wind energy involves a lot of investment to start with, it will surely reap rich benefits in the long run.

World’s Largest Wind Turbine:

Hawaii has the world’s largest wind turbine which has rotors as big as the length of a football field and stands 20- stories tall . One wind turbine can produce enough electricity to power up to 3000 homes.

Unpredictable Resource:

The raw material of this power i.e wind is quite unpredictable. When there is no force in the wind, the blades of the turbine do not move and thus there is no generation of power unlike the other resources where one can estimate how much power will be generated in a given time. However, if a grid extends over a large area, the average production across the region is much more stable, and wind can be a more reliable source of energy.

Minimal Maintenance Cost:

Once the turbines have been built and installed, there is no major intermittent costs to take care of. No extra fuel is burned to make the wind turbines work.
