I think these days the solar panels and even batteries are quite cheap, but the equipment needed build a hybrid system for a house is still a mess. One can find the right inverter, but not a good match for the battery, the backup/switching system that needs to match, DC fuse boxes, especially for European systems that are 230V and sometimes 3-phase, the progress is not good enough even if the problem is simple enough.
