Solar panels are boon in offering. In my country government is giving too much subsidies on solar panel, but again the corruption in middle is eating up all the benefits. I had it installed at my home for many years as my village did not had electricity, till it was supplied in 2015....having a solar panel.is a relief in itself.
Yeah, it's a nice peace of mind thing and comes with some savings once the initial installation/purchase cost is recovered.
