Since I got a new inverter, I have far better logging of the power output of my solar panels, even on my phone :D
I have a pretty small, 2.1kwp (10 panel) ground mount array in my driveway. Its partially shaded at certain points of the day and year, far from ideal. Nevertheless it looks like we are producing about 44% of our August energy consumption from our solar panels.
Thats better than it sounds, because our electrical consumption is relatively high due to
a) Working from home
b) Having an induction hob electric cooker and
c) Having an electric car that charges from home.
We use about 514kwh of energy in August, our peak is about 800 which is January, and probably due to some electric heating in certain rooms, and more hot food I guess. If we had a new house, with better insulation (this one is insulated as much as it can be given its structure), and larger rooftop solar with zero shading, I reckon we could probably hit 100% renewable in the summer months. Why new-build homes are not mandated to include solar panels is a mystery to me. Its just such an obvious thing to do.
