9.7kwh in NE Derbys. 53deg13' N 1deg22' W
From a 4kwp system (16 x 250W Suntech Black Pearl and SunnyBoy 4000TL inverter
Facing True South BUT roof pitch only 17.5 deg

Had a great peak around 10am and another 3pm but very cloudy around midday when it dropped to 500w. However, even that was better than forecasts - Met office predicted sunny spells around 9am then cloudy for rest of day.

Managed our first 'free' load of washing this year this morning. Sunny spell lasted whilst water was heating up and output just about kept pace with WM after heating finished.

Hi

We are in N Wales and had our system installed last Sat. To date we are reading 58.5 Kw and had some quite cloudy and dull days last week.

Is this good or ave please?

Thanks

Don't think anyone will be able to tell you until you include panel size & orientation.

Probably used most of it. Heating was switched off at 7:45, then used a 400W oil rad to warm up room till solar gain heated conservatory, which then heats the living room. Then on with the dishwasher, next washing machine, electric hob for lunch, washing machine again, followed by lawn mower.

Got to say, my loft (which is insulated on the inside roof joists 75mm) didn't used to get too hot, but I could 'crack' the Velux to get rid of any excess. Presumably, now that 90%+ is covered in thermo-nuclear cladding (PV!) it will now only get ambient gain, no solar gain other than via said Velux.

That said, both inverters are in a cool (and groovy!), downstairs toilet, which itself has an insulated roof, with PV on top, and shading to the East via a canopy (made from ... you guessed it, 2 more PV panels). Wanted to keep both inverters together, so one had to travel to the other, chose toilet as out of the way but easier to access and near the main electrics.

Good day all over?

Only 16.1 kWh here today, damn clouds

We knew the Welsh were tight, but this new levels?

The PVGIS site (re.jrc.ec.europa.eu/pvgis/apps4/pvest.php) seems to be popular here as a guide to what you should be clocking.

6.79kW today. woo hoo!!

Welcome to the world of Solar PV. :hello:
Just to be pedantic (and accurate) that should be 58.5 kWh not Kw but it looks a quite respectable output for 8 days of generation. As EricMears said, it all depends on the panels and orientation.

And the pitch of the roof.

This is what is says on our quotation sheet:
System output 3.9 Kwp, Panels: 20 Phono Solar panel output 195 watts, SMA Sunny Boy 4000TL
Location: N Wales, Roof: South facing, 30 degree pitch
