Best April for Solar

[Doing it for the kids]

I had a similar issue with EON only to discover i was wrong, I had been under reporting
long story

well june is already 25% down so that was nice while it lasted

A few years ago we had a query on a reading. Why was it higher ?
I just answered 'Sunshine' and they left it at that.

This last three months has been the best. March 2nd - June 2nd the solar array produced - 22,000 kwh.
And the light is so clear that it is clocking in at 5.30 in the morning, and also producing at 8.30 at night. Not a lot, but a trickle.

Panels have never been cleaned, but examination after last years' heavy and constant storms showed no lichen and all appears crystal clear. (50 kw - installed Dec. 2013)

Light levels in April where well above average. Wasn't the official data for April something like 650 hours on sunshine compared to an average on around 400.

Well all the extra we made in May had been lost in June now having had rain and grey for nearly 7 days now. Looks like it will be an average June now at best

All this extra sun as messed one of the inverters up, causing random voltage spikes resulting it feed auger sensors going haywire, turn the one inverter off solves the problem. Solar sparky is coming out to inspect, fingers crossed new inverter as still 4 months of Warranty left.

Are you sure it is the inverter and not your main supply, where the issue is. We have had serious issues at one site, where voltage got up to 300 volts per phase. EDF would not believe until they put a tracker on for a week. Solar is giving the distributors all types of headaches.

If it wasn’t the inverter I don’t understand why the issue only happens when it’s really bright and it stops instantly when I turn the ‘noisy’ inverter off.

Difficult to know with visiting the site and doing some tests and I am not able to anyway. However you may be able tp check the input voltage on the inverter. Many you can quiz on the screen.
The reason I say this is that it is highly unlikely that your one inverter can produce so high a voltage that it can override the grid . The grid voltage by law is limited at something like 253 volts and your inverter is unlikely to be able to push that up more than a couple amd should of course cut out at that level too. ( gridvoltage by law must be 230 volts to eothin a tolerance of + 10% or minus 6% )
the only way the inverter could push the voltage much higher, assuming there is a software issue, then it must be the cable feeding back to your meter is not big enough or has a fault.
I expect the distributor needs to adjust the taps on either yours or a local transformer, for some reason this has to be done occasionally

if the inverter goes above 253vac it should shut down and do a restart, assuming the country code has been set to UK

looking like a earth leakage from the inverter, solar sparky said he has had SMA inverters of similar age do exactly the same thing.

well we managed 3600 kwh on our 29.25kw in June vs 4700 in May, a normal June should be about 4000 its been really crap weather here and down again. Think we did 15kwh on Monday vs 195 last Thursday

 

[Exfarmer]

We have had sa well over average June, but nothing compared to May.
Strangely May normally seems better than June and has given our two highest monthly readings. Of course May does have an extra day to June , but technically July should have more daylight hours in theory

I think we had more last june and it rained nearly everyday. Its been another well below month. The only 2 decent ones this year are April and May

 

[Wombat]

Well a week into July we are already 45% down on where we should be

 

[chickens and wheat]

My 100 kw is nearly installed . minus 3 broken panels,( big panels 395w) so the predicted forecast is rain and glume

And the cricket started today so after 12days of crap thats the summer gone

 

[Wombat]

Half way through July and 28% down on an average July

 

[Wombat]

So 3400 in July another crap month when normally it’s again about 4000

So since the high of 4700 in May June did 3600 and July scraped 3400. Was hoping for 12,000 in 3 months but finished a bit under
