I'd suggest asking the folks at https://lun.energy https://lun.energy, to start. You're right that our site doesn't yet work for homes outside of the US, unfortunately. The approach would be similar, but some different equipment and home configurations to consider along with different data sets (fuel pricing, weather, grid emissions, etc.) -- I'll keep an eye out for good resources, and would love to help anyone who wants to try to build it!
