Solar Panel Update

After a year, the performance did not seem to match what was estimated. We generated less than 2000 kWh whereas it should have been closer to 2700 based on mean solar hours. The data for the last 9 month indicated that this year would be no better.

I suspected a problem.

I contacted the supplier and they asked me to keep daily records which I more-or-less did for several weeks. I also obtained the solar radiation figures from the Bureau of Meteorology.

I was supposed to send them in, but I have not had time to do this.

Then, about a week ago, I noticed that the inverter was off - the circuit breaker had tripped and so had the one in the meter box.

Resetting them made no difference, so it seems that my inverter has died.

Last week, the inverter was replaced. It has a different UI which includes the energy generated so far for the current day down to 10Whr. Very useful.
