I spoke with various equipment manufacturers and asked them how many btu's were needed.

meh. The only way solar would be useful would be to have a solar plant similar to the mirror based fields in the mojave or the few in spain that are working with hot salt towers... You'd pretty much have a massive sized generation plant to produce consistent steam for your purposes of stilling or mash cooking.. there are some homebrew ways of making heliostats to acheive this, but on a small scale the materials are just too spendy for the ROI to be useful commercially.. now, if you could get a waste steam link from an existing power plant.. that's the hot lick right there..
