MassSave has big new rebates for moving from gas heat to all minisplits. I’d start there and then add solar with batteries if your roof exposure works for it.

Completely uninformed guess is that an electric water heater paired with electric solar panels will be better than using roof space for solar water heating, but that’d be worth confirming too.

I saw a heat pump equipped electric water heater on a recent This Old House episode, adds a ton of efficiency and might be feasible?

Maybe leaving the gas water heater in place until you get solar electric would be a good compromise.

I've heard over and over that solar hot water tends not to pencil out as good as solar electric + electric hot water due to near-inevitable maintenance costs associated with solar hot water - if you can even get a system installed, they tend to break a lot more over time.

I can see that happening…

it’s 3am on a Friday night. Do you go to big box in the morning for a replacement or spend $$$ and living the cold water life waiting for the solar replacement.
