I have a 4.8kW system on my 1700sqft home here in rainy Portland OR and I am net-zero (and that's with everything electric - heating and cooling, water heater, cooking, etc.). But I am also in a certified Passive House, which makes it quite a bit easier...

Building passive houses makes so much sense. Did you build it yourself or buy it?

Bought - I was very, very lucky to have gotten it. But the builder/architect who made mine have built six so far in Portland, none of which have sold for much more than market prices. There's a lot of debate about how necessary going all the way to PH is, there's a "Pretty Good" house movement of just doing more generous insulation / other efficiency improvements, which is also much better than doing the bare minimum required by code. Less is more, either way.
