Renewables: "talking 'bout my generation"

20.1 kWh today.
Ran dishwasher and also the Heatbank temp increased from 62 (I didn't check it but that's it's normal temperature mid morning) to 72 deg C during the day. Since I could quite safely run it up to 95 deg C that's looking good for the really sunny days I'm hoping to get in May, June, July & Aug.

Weather forecasts were, to put it mildly, confused. One lot told me I could expect a cloudy morning with some sun after lunch; others thought it would be sunny am but cloudier pm. In fact it was getting sunny by 9am and continued thus until after 5pm although there were a few brief cloudy intervals throughout the day.


87.39kWh in April so far (6 days)
IF that continued for rest of month, I might expect 437kWh for the whole month. Compare that with a pvgis target of 353 or 381 (old vs new) ! Might be 24% (or 15%) above forecast (or if weather changes could be 50% below :mad: )

8.3kWh today, 4.15 O's, fair to middling but pretty amazing compared with most of the last two months. Not much sun forecast for the next week.

A decent 19kWh (4.75 O's) today. Don't think i'm losing too much generation with my slight shading issue on my SSW system if Erics numbers are anything to go by.(He's not that far away):(

Cheer up chaps. Met Office still haven't bought that new bit of seaweed ! You may well do better than they say.

5.93 O's 23.75kWh today on the panels - near sunburn for me sitting out watching rugby - hadn't expected it to feel so warm! That's what spring is supposed to feel like.

6 O's on the nose today, 4.83 yesterday and a measly 1.62 O's Thursday. Well ahead of PVGIS estimate so far, long may that last!

Not really bothered if we do have 100% cloud for rest of day. I'd recovered lost ISA interest by 10am and currently on E=5

Forecasters will tell you anything ! They hope you'll remember the days when they got it right and forget the ones that were wrong.
