No fun to put my ignorance online, but I'd like to explore one question. Let's say, for example, that Hawaii Island gets (essentially) 100% installation of consumer solar. Everyone will want to sell their surplus to HELCO, but that probably means more energy than the utility can absorb. Energy storage seems to be missing from this discussion. Is it sensible to increase a homeowner's cost by having them install a storage device like Elon Musk's forthcoming home size battery? Probably not. The rush for solar seems predicated on a "rebate" for surplus power returned to the system. It seems that the Gold Rush of selling back to utilities is over. Will the new financial configuration allow more homeowners to afford solar?
