I'm going to be in your similar shoes this year! Just getting the house built and I am going to have my horses home with me for the first time. I'm going to get some sort of shelter up for them, but it's just going to be electric fence to start. I may or may not have power dug over from the house right away.
I haven't any experience with solar fencers, but I know my family (cattle ranchers) have used basically car batteries to charge fencers when we would (from time to time) put up electric temporary fencing to graze the cattle in certain areas. Yeah, would have to change/charge the battery every so often but it worked. So that might be something to look into as well too.
I have myself on a list to get some permanent corral fencing up this summer. I like that idea because it is something more "secure" to have them in, than the little line of electric fence I am going to put up, LOL. Of course, my two guys are pretty well behaved usually and respect the fence well.
I'll get a waterer dug eventualy so they have heated water over the winter, but that will start with a big tub and a hose run from the house. Until I can get a frost free pipe dug.
So many things to do this summer! My list is huge.

It is not enough to know how to ride; one must know how to fall.
