Major Developments in Roof Wind Turbine Power
The world is potentially at the point of being self sustainable. We have the technology to develop energy to power houses with sustainable resources such as solar and wind but the cost of these products are still what is holding us back. One such product which is making leaps and bounds is the roof wind turbine. These have been on the market for quite a while but with recent developments they are much more affordable and efficient.
Previous roof wind turbine models were overly bulky, not highly efficient and quite limited in their operating conditions. The period of time to pay back these models in regards to the money you would save using them was extremely long due to their cost to buy and install. Taking into consideration their maintenance costs this pushed the return period even further back. The newer roof wind turbine models can usually be installed by a good electrician and a far less costly.
As a whole the small wind turbine industry is booming. It was up by about 70 percent last year on the year before. The roof wind turbine market is starting to push this even further as it is taking a larger market share. People are seeing the light literally. they are getting almost instant independence from the grid with a good roof wind turbine installed.
The new model roof wind turbine products have made a big impact on the length of time to earn back the cost to buy and install. For older models you were looking at about 20 years before you saw a return, with the new models you are looking at about a quarter of that.
Until the 31st of December 2016 the government has an incentive program running for small scale wind power systems. Roof wind turbines with a capacity under 100 kilowatts are granted a 30 percent rebate.
Traditionally wind turbines had to be attached to a tower. First the tower needed to be erected which was a problem in itself as it had to be approved by council as well as strong enough. This also added to the cost. With advances in the engineering of the latest wind turbines they are able to be attached directly to a roof eliminating the need for an eyesore of a tower.
Modern wind turbine systems are now using hubs and bearings instead of a gearing system. This has been a major advancement as the efficiency of these devices has been greatly increased. There were two main problems with gears, one was that they wasted energy to start turning and two the gear box also wasted energy generating electricity. Magnets are now used to generate electricity instead and as a result increased efficiency by at least 25% . Other advancements in technology are larger intake areas as well as replaceable turbine blades of course adding to the efficiency and reason to invest in such a product.
