I've had a grid tied solar system for 15+ years. With the enormous tax subsidies back then, it's broken even. There's about a 1.5% decrease per year in production. I'll have to replace the whole thing sometime in the next 5 years. This article paints a very rosy picture of what to expect. In a non-grid-tied system, you have to deal with batteries and a bunch of other issues. This is not cheap. And it is a recurring maintenance cost. Are you going to do that maintenance every few months yourself, or pay someone to do it?
