Hi,
I am trying to get a cabin build permit approved in Washington State. One of their requirements is to meet certain energy efficiency levels. I get 1pt towards the minimum of 3 for each 1200Kwh I generate per year. I avg 299 days of sun per year. Probably maxing 4 hours on 12/21 and 12hrs on 6/21.
How do I determine the number of panels I would need? I already have 2x 200w panels.
Thanks
Don Miller
