Our new solar powered coop

Thats such a good idea!!
I am just about ready to wire up my coop door as well. It looks like you are using exactly the same set-up as I will be using. A car antenna with a 12v timer (the same one as you) and a deep cycle battery. I will eventually set it up will a solar charger as well. Is there any chance you can provide the wiring diagram you used? I am also trying to decide what size solar panel I will need to keep the battery charged. What size are you using and does it seem to be keeping up with the use?
Happy to help, I looked for hours on the web and had no luck getting a good grasp on the wiring. One guy with a 3 part chicken door series on you tube was the most helpful, but still he seemed to make it more difficult then it needed to be. a 5 watt panel should be fine. I set my timer to open at 7 AM and then close 30 minutes later , from what I get if the door is open all day the motor is using power, so I give them enough time to get out and then set it to close after that . Let me know how it goes....
Thank you so much. I think I saw the same video series as you as well. He used a relay which I didn't think was necessary. Your diagram is the simplicity I was looking for. Mostly I just couldn't figure out the wiring on the timer. Did you happen to measure the amperage on the antenna? I think I would like to include an in line fuse just for piece of mind but don't know what size fuse to use.
I may go with a bigger panel. My antenna will be extended when the door is closed which means it will be drawing power all night. Although, I don't think it will draw much power except when its motor is actually running.
