This cheap and cheerful wind turbine system is imported into the UK from China by Navitron as part of their range of budget renewable energy products.
It comes with its own tower and electronic controllers for battery charging applications.
It is probably not suitable for grid-connection.

Swept area
The Navitron 200W has a blade diameter of 2.00 metres. This means it has a swept area, or capture area of 3.14 square metres. The swept area is all important when comparing wind turbines, since it directly relates to the amount of passing wind energy the turbine blades can intercept.
Navitron 200W power output curve
The graph below shows the power produced (in watts) for the Navitron 200W at different wind speeds, based on data supplied by the manufacturer.
Whilst the above graph gives an indication of the instantaneous power you might expect from the
Navitron 200W turbine, working out annual power production is more complex.
The only way to know for sure is by measuring your wind speeds using an anemometer for a period of time and then working out what a generator like this would produce.
Luckily, we've invented something that makes this easy, called the
Power Predictor!
Power output
No output data is available for wind speeds about 13m/s, so we are assuming no output (although this may not be the case)
Cost
Price starts at £299 for a package including tower, guylines and anchors, inverter, controller and blades.
Extra requirements include cement for foundations and batteries to complete the installation. Looks like it can be a DIY installation.

Noise levels
Anecdotal evidence of noisy operation, but this may be due to poorly balanced blades.
