If I had to install some equipment at home were the mains are not easily accessible or would result in long cables, I’d immediately think about issuing solar panels to charge a battery, and discard the idea of using a wind turbine since in my mind those are really large and need to be fitted to a tall pole to be effective.
But I’ve recently come across a relatively compact wind turbine that generates up to 800 Watts and outputs 12V to 24V DC.
Key features and specifications:
- Rated Power – 800W
- Voltage 12V/24V
- Generator – 3phase AC PMG
- Rated wind speed – 11.5m/s
- Safe wind speed – 55m/s
- Wind direction auto adjustment
- Number of blades – 3 to 6
- Windwheel diameter – 1.35m
- Material – High-strength PA66 and fiber-reinforced nylon
- Temperature Range – -40℃-80℃
Those are the specifications for the model I found on Banggood ($295.99), and I have to admit with a 1.35m diameter, it’s a bit larger than I expected from seeing the photos. But there’s also another model on Aliexpress ($233+), that looks virtually the same but has a windwheel with only 90cm diameter and a weight of 8.8 kg. It’s rated power is 500W, and max power 800W.
The wind turbine is used to power appliance that requires a fair amount of power, and the photo above shows it installed together with solar panels to power city lights in various cities and provinces in China. But it would be an over-the-top – and expensive – solution to charge a battery powering a single board computer for example. I suppose such a compact wind turbine could also be placed on a rooftop or hill with a smallish pole to power a base station or other equipment.
