Should I remove solar panels or get a solar hot water heater?

I just found out that my homeowners insurance company wants to charge me 0 more per year because I have some old solar panels on my roof. They were put on by the previous owners a long time ago I think. They are for a solar water heater but they aren’t connected to anything because I just have a regular water heater in my garage. They are ugly as hell and I would just as soon take them down as I’d rather have a tankless system eventually anyways. My insurance is already 50 per year for a 140K house (Florida) so its high enough as it is. It seems stupid to pay 0 a year for something I’m not even using. Who can I call to take them down or can I do it myself or are solar water heaters cheap enough now that I should consider one?

How can Solar Panels help the economy?

The only ideas I have are that solar panels would open new jobs worldwide for those who don’t have no jobs, it would help the "common man" with their bills if solar panels become more popular. I need one or two more reasons how it can help the economy.
Try to use the Marxist Criticism as a lens to find one.
