- TheOtherHobbes 8y agoDefine substantial. Domestic PV installations reliably produce a significant percentage of domestic consumption - even in countries like Germany and the UK, which aren't known for bright sun. Countries that do have bright sun typically skip straight to passive solar water heating systems, which can do an excellent job of eliminating water heating costs.
