That's really impressive and well built solar system, for it to last thta long. It shows how durable quality panels are. I have a 6 month old ~3.7kW system (6 panels in total), planning on installing another 6 very soon. My house is surrounded by trees so it's been a bit of a struggle in the winter.
- tpoindex 3mo agoMy latitude plus east/west arrays are a struggle anyway. On the best (presumably cloudless) December day, I got 13.98 kWh. My 12/1/2025 through 1/31/2026 average per day was 10.32 kWh.
- manmal 3mo agoPanels should do 30 years, easy. Inverters will usually fail after 15y, and with batteries it’s unknown what the current gen will do - 15y, maybe 20? Definitely get LFP.
- noir_lord 3mo agoI’m waiting to see what the sodium packs look like before we do Solar PV (it’s on the list but not near the top so no urgency yet).
- malfist 3mo agoSodium batteries are more grid scale I believe. They require seriously high temps to operate and thats best shared in massive banks
- noir_lord 3mo agoNot just grid scale, already been used in EV’s, less temperature sensitive than Li-ion, way more charge cycles but not quite as energy dense as lithium per kg but that’s not a downside in a static installation.
- sgt 3mo agoI've seen cheaper Chinese panels fail after less than 10 though.
- manmal 2mo agoYes there was a generation with plastic back which fell apart. Everybody uses double sided glass now. Should be good.
