I think it’s now required by law in Oregon that new houses include solar.
That's ridiculous. Solar on rooftop is good only in certain scenarios. Like metal roof (no need to remove panels every 10 years to replace shingled roof), in the south (lots of sunshine, and most of our power consumption is during the summer when we have even more sunshine), no shade over the roof, and part of the roof facing south to catch more solar during the winter when the sun is at a relatively low angle. I meet all of those parameters, but how many other people do? Especially in Oregon?
