Ya'll love to hate on solar but mine paid for themselves in about 5 years.

No they didn't. Tax incentives paid for a lot of it. My senior design project in engineering was utilizing green energy to power something. 80% of my time was calculating the economics vs. grid power. In the best scenarios, solar paid for itself right about the lifetime expectancy of the panels themselves. And that without accounting for degradation in efficiency over time. So, if you break even right as it fails, what's the point. We got most everything donated and the point was to utilize green energy, not to save money. So we pushed forward. But economically it's just not a good bet without incentives. I'm not against utilizing them when they are there. Just against pretending it's the perfect solution.
