What would you do for light if the grid went down? I put some components together and created an emergency lighting solution.
The wind generator is a 10W vawt, and the solar panels are 1.8W each. They trickle charge a 12V battery that can be used for emergency lighting or recharging batteries, cell phones, etc. I’ve used this system and it works.
VAWTs (vertical axis wind turbine) work well in a surburban and urban environment. They have lower cut in speeds than horizontal props, which means they’re creating electricity even in low winds. Plus, they run silent so they won’t bother neighbours.
