solar door opener

[pasotami]

I was looking at the henspa site and one of their models has a door opener that at daylight it opens and at night it closes automatically - I am assuming it is light senored. Can anyone give me a name of a solar opener that I could google. I'd like to add that to my henhouse but can't seem to find a place that would sell them. Better yet, anyone know how to put something like that together? From what I could tell from henspa, the door slides up and down at an angle, but there are not any details on it.

Get the parts at the junk yard and use the automatic window motor/control to build a sliding (sideways) door in a track. See the solar/12V photelectric switch in the Alternative Energy Forum to turn it on and off. Seems you could put one together in just a little while.
