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.
@sinabhfuil There is 4kWp on the house (17 x 235W) and 21.6kWp on the shed. But the total that can be supplied by the inverters is only 10.5kW. Though I could potentially use 10.5kW in the house and charging our EVs, while still putting over 10kW into the batteries.
@sinabhfuil There are 54 400W panels on the shed and 17 235W panels on the house.
@ArborealTechie So many! 😂 Engineer came and looked at my place and said, nah, it'd only fit 5 panels, not worth it!
@sinabhfuil Anywhere you can put a south facing shed?😉
