Micro Hydro...When it Rains it Roars. Off the Grid with Karen and Grid

When our dynamic duo have more rain than sun, they open a valve and flip a circuit breaker, switching their energy supply from solar panels to a micro-hydro system. Sometimes, it rains a lot. Enough to spin up their turbine by late Fall, and keep it going until mid-Spring. Sometimes, it's a dry year. But there's always been enough water to take over when the winter sun sinks low in the sky and trees shade the PV array, In this episode, Grid explains how a small system like theirs is built from an existing water supply.
