Old solar panel- I think it's lost it's oomph
Posted: 03 Sep 2025, 10:12
I've had a rigid 130w panel on the roof for at least 12 years, doing it's thing with no maintenance at all. I saw about a year ago that's had an impact somewhere along the line, and it's all crazed/shattered.
Now using the victron app, (smart solar 75/15 controller), the max peak wattage I get out of it is never above 75, on the clearest, sunniest days. I don't remember if it was ever higher than that, now I can see it with this controller.
Should I be seeing closer to 130w in the real world, or is that theoretical peak nowhere near achievable?
Fridge is struggling more to keep up with things.
Thanks!
