Solar panel production figures

Not a bad day bloody real hot we made 29.70Kwh for this last day of the month exported 13.50Kwh and wish the weather had been like this for the month but a day or two with good numbers is just not going to cut it. This months numbers I will work it out later but we are way low on the predicted number for the month.

House System is East West
down in not so sunny Devon.
East 8 x 420w panels 45 deg pitch
West 10 x 420w panels 45 deg pitch
Givenergy Gen3 5kwh hybrid
2 x 9.5 battery's

Workshop system is South/East
2440w of panels two 720w strings
one 1000w string
Hybrid inverter with 4x 12v 100Amp
Battery's
Plus grid tie inverter as well
 
Not a bad day today 51.1 generated 41.53 exported.

I cant do a full months power stats as OI kicked on to charge the car at 21:30, but here are this months solar stats:

Target: 1072 (34.6/day)
Generated: 1182 (38.1/day)
Exported: 964 (per GivEnergy)

Like everyone else, I beat May (1133) but not June (1378)

Since my install was commissioned on 12th Jan, I've generated 5,549kwh.

I'm also well ahead of my annual target, up by 383kwh, thats not bad considering I missed the first 11 days of January and was 50kwh down. I only need another 1,978kwh hit it the annual target.

Full spend for the month to be confirmed tomorrow.
 
So hears the numbers for the month as said July has been a poor month in Mid Devon
on the house
system fitted 25th march 2024
system target of 6642Kwh a year

march target 585 made 312 system only in half a month
April target 731 made 578 152 below
May target 797 made 840 43 over
June target 898 made 928 30 over
July target 930 made 799 131 under

Workshop system
July 243 made

I finished the day on 56.76kWh, exported 32.92kWh.

I also found my mistake with my uploads to PVOutput so that's now sorted. I'll need to fix the data for today but after that it should be plain sailing.

Those of you who are mentioning monthly targets, where are you getting those figures from? PVGIS?

My installer gave me an overall annual figure only which is what mine is based on.

PVGIS gave me a number which was significantly higher. So I used the PVGIS generation profile and applied it to the estimate from my installer (which was similar to quotes I had from other installers).

Not heard of PVGIS before but I originally used this.

Solar Power Calculator breakdown by month

See how much solar energy you will generate across the year with this monthly breakdown graph. Check to see if you are on target throughout the year.

But for July
Estimate 510
Solax Portal 547
Givenergy Portal 512.1
Difference between the two portals is ~1.12 kwh a day (if divided by 10 for generation period its 0.11kwh per hour which seems normal)

I'd not seen that site before so thanks!

Given me an August target of 997kWh so lets see how well we do!
