Yes. It literally says: > The cost assumptions assume utility-scale solar panels and batteries in large parks. Smaller-scale rooftop solar and home batteries would cost 2-3 times more. I've installed domestic solar several times. The main cost isn't the panels or the inverters - it's the scaffolding, labour, and wiring improvements in the home. If you have a tall or complicated house, it'll cost more.
