Coming from someone who owns them-
Nah, it's not worth it.... at least, if you strictly look at "saving money" overall.
ROI is on average 10-25 years, depending on your current cost of energy. The components/inverters/etc, are usually rated for 20-25 years.
At least- this applies if you have a properly licensed contractor install everything. If you do everything yourself, its extremely worth it, and would achieve ROI in a decade or less.
those parts (panels, inverter) are easy to replace since all the installation has been made, and they will be cheaper than they were when you bought them. Im my case panels + inverter were about 40% of the total cost. I imagine a similar powered panel will be way cheaper in 20 years
I'm gonna wait a few years, until prices go waaay down.... and I plan on doubling/tripling the PV capacity, which will make everything much more effective, as well.
