"allowed gen times", for God's sake... Too often too many people choose to exercise this their "right" and run a generator from 7 am to 10 pm. For all kinds of reasons: microwave - like they would've died without it, toaster, espresso machine, breadmaker, iron, big screen TV, you name it... I'm trying to avoid such places. Ever heard the sound of a "quiet" diesel generator? It's un-f-king-believable.
HiTech - there is almost no output in rain. You'll get lucky to have few amp-hours from 400W panel.
