New York City bans natural gas in new buildings

How many solar panels do I need to get 12kw in winter in the Pacific Northwest?

Answer: per this solar axis[0], we average 242Wh/m² in January. Assuming 25% solar panel efficiency, this gives 60.5W/m². To get 12kw would require 200m² of solar panels, or 45"x45". If we covered our entire house with solar panels it'd be 80m²=4.8kW.

So it would take care of over 1/3 of your energy needs with most of the rest coming from (I assume) hydroelectric generation. Doesn't sound that bad to me.

we're pretty much entirely on hydro here, so you're correct. our house uses mostly electric everything. my comment was more that solar panels don't magically let everyone live off-grid

Did you mean 45' (feet) or 45" (inches)?
