We fitted solar thermal (hot water) panels when re-roofing in 2006. They've been great and very cost effective. Added solar PV around them in 2011. In 2023, using over 10 years import/export data I calculated the optimum extra PV/batteries needed to satisfy most of our power needs and covered a shed in PV. The shed is south facing with a 20 degree roof. The vertical panels help in winter.

BTW, I use Home Assistant (as well as my own software) to monitor and control my system. This is how my display looked when the sun came out one day last year. I turned on the heat pump to reduce the charge going into the batteries, which were charging at 15kW. EV was also charging at 2.2kW (to prolong battery life). @X31Andy you can see the individual strings here.
