Last year I had 15 PV panels installed on my semi-detached house. Only four panels face roughly South and the balance face west. Attached is the output profile for the installation. 3.3MWh was produced in 2017. I also installed a Tesla Powerwall at the same time allowing energy not used during the day to be stored and used later. I did manage to consume 2.82MWh which represented 37% of my total demand. I still reckon it will take at least 12 years to recover my investment. Fingers crossed.
