Things to think about:
- Great when combined with solar. Wind can blow at night!
- Obviously, wind is needed..
- On the other end of the spectrum, too much wind can tear a unit apart. A unit may need to be taken down if gale force winds or stronger are expected. Be aware of the limits of any unit you invest in!
- Can easily use a DC motor. (easier setup, but will most likely be a brushed motor. This means after so many rotations, the brushes will need to be changed. This applies to any/all DC brushed motors, however in this use-case of energy generation, one needs to be aware of this consumable part!)
A major point that should be considered is the concept of "cloud anchors" and increased cloud cover during the GSM. This could potentially translate to decreasing winds.
Common units available for home use
Smaller turbines can be acquired below the $1,000 mark that are capable of producing 300w~900W (at 12v-24v).

- As written up here,
- This model is built to survive 80mph winds
- There is also an "LE-V150 Extreme" model that is built to function down to -40'C
- Charge Controller: DL-300 or Tristar 45A

any real-world examples of chaining the smaller home units? TODO: chaining toy turbines for small-battery charging.
