First let me apologize if this has been posted elsewhere, I've been researching like crazy abd cant seem to find the information I really need, so as I've learned through my past DIY excursions, ask the pros with the Passion for such.
Here's the situation, I am constantly traveling in the nortern states and Canada with my dogs Bella and lucey, and as you know it gets cold out there, I work outside and have problems with my dogs water becoming frozen.
Here's what I would like to do . I would like to build a system and create a pad that would heat by solar power, as I am away from AC power to use a conventional pad. It needs to be able to hold a temperature above the waters freezing point (32f) throughout the day and night.
Now I thought this would be easy and has proven to be quite the obstacle. But I assume I would need a solar panel large enough (size undetermined ??). That connects to a cord with positive and negative connected to a solar battery system, that then runs to some.sort of pad. My next issue and largest I would imagine, is creating a pad. I've read tha you can use wire (the sort from a toaster) in a small guage to create heat, or even use a series of resistors.
I know I lack the education in this field but I imagine this project is barely a step towards some of the large scale projects otherwise mentioned in this forum.
Guys any help would be much appreciated,
