Has anyone thought of using solar panels to power any electrical components for the coops? I recently bought a small solar panel that charges a 12V battery but I'm switching somethings on it to power a box fan during the hot months and going to use it to power my heat lamps during the winter. During the summer I can hook it straight to the fan but during the winter since I'll use the lights at night, I'll have a 12V battery hooked to the panel and then run the lights off of the battery at night. Anyone else tried anything like this?
