Domestic Windmills 101 – Technical Facts on Home Windmill Generator
A home windmill generator is exactly what you need if you want to get your electric bills off your monthly load. There are plenty of other options, but a windmill generator is one of the best because it can be easily built or installed in your home at a minimal investment.
Technical Data to Get You Started on Wind Power Generation
A windmill for home power works best if it is installed in an area with at least 9 mph of wind speed or if it is around 60 feet above ground level. It consists of a tower, a shaft, a base, blades, and a generator. The blades are attached to magnetic generators that convert wind energy into electrical power that can be used to power electrical equipments.
The typical windmills for home electricity will cost you anywhere between $30,000 and $45,000. This means that if you are being charged at least $200 per month for electricity, your home windmill generator will start paying off in more or less 15 years. If you don’t use all the electricity produced by your generator, you can sell the extra power to electrical companies, which will shorten the payback period for your investment.
Home windmills come in different sizes. The size also affects the amount of power that they can produce. Small windmills for homes can produce just enough power for basic electrical usage of small households. They are also more suitable for homes with limited space such as those in subdivisions. Consequently, larger homes will most likely require larger generators. Usually, the home windmills are:
• Between 30 and 40 meters or 100 and 130 feet in height
• Between 6 and 8 meters or 20 and 26 feet in diameter
• Priced between $600 for the smallest and $9000 for the largest
How to Make A Homemade Windmill
It is easy to build your own electricity generation system using wind power. Before you begin, check your electric bill and find out how much electricity you use every month. This will let you know how big a system you need. The total investment your system will require depends on how much electricity you use.
Take note, however, that a windmill can only produce energy if the wind flow and speed is good. So you have to choose the best position for it.
You can also use this formula to figure out the output you can expect from a windmill of a particular size: blade diameter (in feet and squared) x wind velocity (cubed) x 0.01328 = kwh/year.
So if you know your wind speed and the expected output you want to generate, you can then calculate the blade diameter ideal for your home. If you don’t know your wind speed, you can check out the Energy Efficient Choices website, which includes wind data for various US states.
There are online calculators that are designed to help you with these calculations. The calculators can even also come up with your annual savings and an estimate of how long it will take for your investment to pay off.
If you feel that you will be unable to do the job, it would be best to hire a professional to install your home windmill generator.
