Solar in Portland: What to Expect
Portland has a genuine four-season climate, so solar production swings between strong summers and lower-output winters. Net-metering or production-banking rules in Oregon matter a lot here because they let summer overproduction offset winter use. A south-facing, unshaded roof and an accurate usage analysis are the keys to a sound estimate.
