I have taken the playhouse off the grid. This weekend I installed a series of 15W PV Panels. The panels feed 60W into a 7amp charge controller which at this time charges a 55AH deep cycle battery which allows a 110v 200watt inverter to pull power from it.
Currently I am using this to power on the coop lights at night to lure the chickens into the coop. I’ll also wire up a switch in the playhouse for the kids to turn on/off the lights, a fan to exhaust some of the heat in the playhouse and a series of garden lights.
