I've been looking at our household energy bills and noticed solar panels are finally becoming affordable for middle-class families, but I'm wondering if the real win is pairing them with battery storage or just feeding excess power back to the grid. In Germany, feed-in tariffs have made rooftop solar a no-brainer for many, yet here in the States, net metering rules keep changing and utilities are fighting back. I've read that the average payback period is now around 7-8 years with federal tax credits, but does that math hold up if you factor in maintenance and inverter replacements? What's your experience—should most homeowners go solar now, or wait for more efficient panels and cheaper batteries?
