Solar panel production figures

24.3kWh generated, 13.6kWh exported and 0.6kWh imported.

Next few days look uncertain. The forecast suggests cloud which may or may not burn off. Today it lasted until about midday and cleared.

Just to say, I was advised you should not wash your panels with tap water. Although I guess where you live will make a lot of difference.
If you wash panels with tap water you risk covering them in calcium as the water evaporates.

I was told the same, but we are in a hard water area. I've never washed my original panels, and they have been installed for nearly eighth years now.

I mean it makes sense. Whatever is in the water if it evaporates is going to remain, and calcium is a real pain.

If I was going to wash my panels I would do it with rainwater (or grab some RO water from work ;) )
 
35.6kWh yesterday, spent a couple of long meetings basking in it myself. 4.7 today so far and it's barely 8am, the joys of being ESE and long summer days. :)

Might as well take a punt at this, anybody in the essex area have a 5kw south facing system, would be interesting to see generation.

Have you had a browse of PVOutput.org, you should be able to find one there, you can filter by size and orientation, then look for the post code you're interested in, have a look on Map View.

@alphaomega16


I did a quick look for south facing systems between 4000-5000W that are due south - however you can add postcode ranges - I just added southend on sea.
 
Looks like I'm going to break 800kWh for the month - I doubt I'll ever get 900 or even 1MWh with my system. However, that's WAY more energy than I'd ever use in a month - in fact I've generated more in the first 1/3rd of the year than I would typically use in a year.

Nice. Ive breached 600 and when I consider my target was 468 I am left wondering if it was just a superb solar May
@ronski you have lots of history, was May exceptional this year?

I asked this a little bit ago and Ron-ski confirmed some of the range he's seen, it does seem that overall it will wind up nearer the top end:

Solar panel production figures

31.8 here, picking up again, last month seemed to have fewer days of heavy cloud. Quite envious of Welshman's efficiency today :) ( and Ron-ski's ridiculous outputs! )

Can only see this page from that link, I guess you have a diff number of post per page set

Out of the last five years it's the second best, currently my SolarEdge system is sitting at 606kWh, best year was 2020, which was exceptional at 713. I'm at work so only looking on the app rather than logging in to the web dashboard which goes all the way back, I would say it's an above average May.

If you want to look the entire data is uploaded to PV Output, click on the combined system, then there is an option to see the two separate systems.
 
April didn't turn out so well over here, maybe I am comparing it to the covid one where we had wall to wall sunshine for weeks. May, I counted had ten poor days overall but this week has made up for it. Looks like we dodged the lows and the Mediterranean region got the bad end.
 
April was poor here as well, but this May is on par with April 2020, this is the 4th week of virtually unbroken sun, been hazy a couple of days but still blue skies.
No rain in that time, running out of water for the garden.

We're good for another 10 days of the same weather.(mid Wales close to the coast)
