Photovoltaic - solar panels. I'll post pictures when it is up and running. I kept the turkeys in their pasture, so they wouldn't get in the way of the installers. They loved hearing all the poultry and the "chatter" and went to visit them several times. While the installers were here, there was such a commotion I had to go out and investigate. I got there in time to save the chicken hen the hawk had its talons on!
