Greetings my fellow heatwave sufferers! Over here, we navigated May unscathed and we are bracing for June.

I wonder if I will live to see window shutters becoming the norm in the UK as they are in South Europe. Sooner than that I expect Mars and the users of the forum to open topics on using the cooling capabilities of the ASHPs. Till then and speaking from first hand experience, plain fans can be real relief. 

Below is our May output. You can see that this year we had more overcast days in May. 1st of May in particular was like November…

@mk4 Here we are with June 2026 Solar production then; worst year yet - not by much but then, one must always look on the bright side I suppose!

Our June 2026 generation is down too. We generated about 630 kWh when compared to 690 kWh last year. This June is almost the same as 2024 June though. Last year was great for solar overall. Interestingly, the heat wave hasn't been helpful and seems to throttle electricity generation down when it's very hot.

You weren’t alone, we were considerably down on last month and last year. But now that flux is back the revenue is worthwhile again, so I’m a happy bunny.

@trebor12345oodles Greetings! We have been hit by a failure, one of our strings went down mid-June and thus we are loosing the highest yield months….the installer was practically a middleman using subcos, the subcos have dispersed meaning it will be a while before operation is fully restored.

Luckily we still have some 8Mwh reserve already with the DNO and this should get us  through next winter unscathed.

How are you guys faring with the heat? We are reading some horror stories in the news (though mainly for continental Europe).

@chandykris Indeed, the elevated temperature does attenuate output from the panels quite significantly - in fact, you might say: Hot weather, they don’t like it up ‘em! Regrets, Toodles.
