"evry couple of years" .. umm nope. Try every 10-20 years for the inverter and every 20-30 years for the panels. Roof-top solar in Australia is cheap and almost ubiquitous.
- bregma 4y agoAnd the batteries?
- eldaisfish 4y agothis is far from the truth. NREL have great reports and ongoing research into how often solar panels fail. You are correct in that it isn't every couple of years but it is not as long as 20 years. The number of solar PV panels that have been around that long, let alone survived that long is small.
- ryathal 4y agoEvery couple years is probably more accurate. Hardware fails all the time, especially at scale. Hard drives fail all the time, solar equipment isn't magically different. Once a full neighborhood has solar, someone will have a defective panel, a defective inverter, an improper install that needs to be redone, storm damage, panels that need cleaning, panels that get damaged from cleaning, or a building gets renovated/replaced/destroyed.
