So, I see conflicting answers. I intend to mount this on the outside of a chicken coop. Will the weather destroy it?

Sun and weather will eventually destroy the materials. That said I would estimate 6 to 10 years of useable life, if reasonable protected is provided. By then they'll have something much better or you'll have no need for it any longer.

Is there foldable kickstand behind every panel? Complaints of others say lack of center support is a serious issue..

Three of the four have a kickstand I usually put my battery behind the empty one. No problems for me

Will this work for an enginstar 150 power station?

I don't see why it can't if it has the same connectors.

I have the 350 watt power station, will this solar panel only charge it up to 100 watts? and if so how long to charge?

Watts and watt/hours are two different things. This panel will put out a constant output of 100w in perfect conditions. at 18v, that means it would be putting out ~5.5a. If you have a battery in watt/hours or amp/hours, you would just need to do the math to figure out how long it would take to charge the battery bank completely.
