I'm pretty close to dropping household insurance. Over time, it hasn't paid anything like what it costs, and we could afford to replace the house should it become necessary.Batteries in general are grossly overpriced for the amount of standalone power you get out of them once the sun goes down. Unfortunately, we aren't there yet when it comes to storing power.
As for insurance roof replacement, we had out 18y/o roof replaced at 100%, even though is was 60% covered by panels, because of the damage that it took. A storm 2yrs later laid waste to this new neighborhood and most people got both roofs and windows, plus a lot of decks. That one was a microburst that sat over the neighborhood for almost 10min. It's also why our HO ins is almost $4k/yr with a %-based deductible - you can't get fixed amount anymore.
