My 5kw solar PV system (installed Jan’15, Perth, on single phase) is faulty, I think the inverter has failed and is out of warranty. I’ll get the condition of the panels checked but would expect another 10+ years out of them. We’d been generating about 20kwh daily from the solar PV while using 30+ kwh daily for a family of four, though I haven’t profiled our use pattern throughout the day.
I’m now considering what the best options from here might be given that tech has improved and I’ll likely get an EV within 3-5 years. I could simply replace the inverter and stick with the current setup for at least the next 5 years, or take advantage of incentives by upgrading the whole system to 8-10kw, perhaps with a medium sized battery, with the aim of reducing my reliance on the grid without going completely off grid. I’m not too bothered with maximising feed in tariffs. I’ll be able to afford a decent upgrade, but would want a reasonable chance of payback from grid savings within 10 years. I’m not keen to send the existing panels to landfill.
Thoughts?
Which inverter has <10 year warranty?
