Carey - thank for the reply. To clarify - we are using an off-grid PV system currently, so are very familiar with the equipment, maintenance, and usage considerations. We love being off-grid. In considering buying a different house, one that is currently on-grid, we would likely want to add an off-grid PV system to it at a later date, and disconnect it from HELCO. Your point about plans, both electric and structural is well taken, and exactly the sort of suggestion I am looking for. We are also considering the possibility of installing an off-grid system, but leaving the HELCO connection in place for use as a backup during extended periods of low or no sun. Thanks for your helpful comments !
