I was confused too, because my husband used to take day trips up to Steven's Pass, and if it was impromptu enough, he would ski in his jeans. I thought it sounded dumb and he replied "If you don't fall, you don't get wet and cold." Which made sense for him.

We're on an EG4 system out here in Western Washington. We used a company called Signature Solar, out of Texas. Amazing customer service, even when we had a crazy catastrophic inverter failure last summer.
