How to Build a Solar Dog House
You will need to use either an existing piece of concrete or purchase at your local hardware/landscaping supplier a slab of concrete. - Make sure this is level for the safety of your pet
This concrete will work as a thermal mass to exchange the heat into the actual house portion of your dog's domicile/home.
Once the slab is installed/hardened place your dog house or build the dog house onto the slab. - Plan on trying to leave an overhang to the outside of the pad of approximately 1/2" all the way around the concrete pad.
You will depending on the size of your Plexiglas begin to build the frame of your Solar Collection system. - Be sure it is tall enough/big enough space for your dog to lie/walk about in. To keep warm they will lie in this are during sunny days in the Winter months to warm themselves.
You may want to make this section removable for the warmer months of the year. Utilize brackets or some type of removable connection system.
Be sure to make this air tight to keep out any excessive drafts! Caulk any gaps.
Build your own cover to place over the Plexiglas at night to aid in keeping the warmth in!
