Solar panel meter lifespan

[Dman2]

Just a thought, but seeing as how we have to change our RHI meters after 10 years
Does the same apply to solar meters??
Ours coming up 10 years

No doubt Ofgem will crank up some new rules again

I think in theory we are supposed to get them recalibrated regularly, which I do, currently on a 20 year rolling programme

It's a bit different with biomass as heat probes can drift out of calibration etc. Mine drifted in the wrong direction, it cost me a fortune in lost RHI.

Measuring a flow of current is easier, and I think the tech is less likely to degrade over time. I don't see why meters on the export side need to be considered any less reliable than meters on the import side, and mine are ancient.

our iskra meter says in the manual, never needs to be re-calibrated after leaving the factory.
Ofgem accepted this when they asked for a calibrated check to be done.
Think I'll buy iskra meters in the future, when required to.
no idea how a calibration can be done, because would likely need adjustment in the firmware of the device.

OH yes, I know, throw it in the bin and buy another.
Seems to be the way now days.

Since the inverters normally read total outputs it is well worth checking they do match the production meter for your own benefit

yeah your right,
I actually have a once per second (approx) feedback microcontroller on my PV and CHP gen meters, so I know the output at any given moment in time.
