I bought my first set of Solar Panels 33 years ago. Those panels are still on the roof, have had zero maintenance, and are still happily running my small fridge.

The Battery story is somewhat different. My first set of batteries finally died a few years ago. Likewise I've probably replaced three or four inverters in that time.

Whatever, my off-grid Solar power system has repayed itself many times over.
