Here are some screenshots from my year of solar. (the system didn't get turned on until mid-january 2017. I used 12.2 cents per kw as our 2 electric cars push our household up into the higher tier quite quickly; plus it is closer to reality after you factor in the fees.
We do have a significant shading issue in the morning from a tall tree that sits southeast of our house. Not sure if it is worth taking the tree down, but I may work on thinning it out over the next few years.
Ironically our highest day of production in December was on Solstice!
Happy New Year to you all!
Cheers to all that helped me along the way!
