Earlier this year I transformed an old shed into a chicken coop, and now have restored an old nieghboring horse stall/tack room into a pig pen w/ store room. My dilema is that there is no power to these two buildings and they are several hundred feet from our AC power at the house.

I am looking for a reasonably low cost solution for creating a 12v power source using a used PV solar panel, descent sized deep cycle AGM 12v battery, and 12v lighting in the three spaces (coup, pen, storage room). I will also need the capability to have a timer on the coup lighting so that we can extend the chicken's laying through the winter - and hopefully some motion sensor exterior lights.

I am having a hard time pulling the resources together to make this happen.

Any recommendations on how I can make this happen?

Thanks, as always, for your insight and recommendations.
