This is an area of big interest to me, too. You may know some of these things, but let me share them with you, just in case not:
Home Power magazine has all sorts of information on equipment, pertinent NEC, training, examples, etc. They'll have articles comparing turbines by model and size, calculations for grid-tied solar, etc. It's great stuff if, like me, you're justing getting into it. I have occasionally seen advertising for training in your area in the past.
Solar Energy International (SEI) offers hands-on training (though for an electrician, it might be pretty basic stuff-- then again, photovoltaics aren't that complicated to begin with). Check their web site.
NABCEP offers certifications for renewable energy installers. I think their web site mentions places where you can get training. All their requirements for certification are listed there, too.
I hope this helps.
