that you are, mine are two stories above a concrete patio, I'd need a pole 30 feet long, I'm not going up there on a ladder. It's doesn't really matter much in December or January, there is a big pine tree to my south and it's shadow crosses the array midday, but by early-mid February the sun is above the tree and sunny day production really takes off. Typical winter consumption for my family is about 19-20 kwh/day, summer it's 16-18/day if AC isn't needed.
For heat, a typical 30F day the house uses ~10k BTUs/hr on average, on a 0F design day it's about 30k BTU. I'm curious what a water heat pump in that output range looks like from a cost and equipment footprint perspective, gas boilers don't last for ever.
