Hi,
My names is John. I own Terrapin Wind and Solar Co. We have a solar powered trough de-icer we sell for $350 with no battery back-up and $550 with battery backup. It makes watering livestock in the winter in cold climates much easier. It's an aerator which keeps the water moving by way of a bubbler in the trough. They work down to about 0 degrees. After that water has a tendency to freeze. It also keeps the purity of the water much higher by creating movement. Call today and find out more info (928)337-2600
