Yah, first time posting here due to the install happening late Oct.

One thing I noticed is that East/West splits really aren't great in winter.

I would think I might have got to over 150kWh if it had been there for the whole month, I seem to have missed out on a few good days at the start of the month!

Manic Moran · 01-12-2021 6:36pm

Finally, the summer is over, and I have generated more solar than I used. 11.5kW system, central Texas. 48% of power consumption was produced at time of generation by the panels, the rest went on credit, the net export was used to offset some of the natural gas bill. (Local utility supplies both gas and electrical), but because of the horrible 'excess' sales rate, it dropped the bill very little. I get a 1:1 kWh credit for exports if I use the credit within the same billing period, but excess left over after the month is sold for about 15% of what I buy for.

Lil Bit exported on the "good" days at the start of the month when batteries were charged to 100%.

Should be doubling the battery storage in Jan.

Already past the 400€ per year "saving" prediction on the Solar only, and 20€ short on the 400€ prediction on the battery system.... yay for increased energy prices!

On track for a 8-9 yr payback.

Just hit the 200kWh generated since going live about 7 weeks ago!!!

bullit_dodger · 15-12-2021 1:15pm

Nice one Andy! You were setup roughly about the same time as myself (last week in Oct me) and your kicking my butt. My details for this year so far are

Energy Data : 2021-01-01 ~ 2021-12-14

Generation to Home: 140.9 kWh

Generation to Battery: 2.3 kWh

Generation to Grid: 1 kWh

Total: 144.2 kWh

And I've a slightly bigger array (5.3Kwp split 1.4kwp exactly East/3.7 Exactly West). Also in Dublin like you and it's sunny out there today.

South facing arrays , or even semi south facing in these months of winter really improve the production. Still I'll get my revenge in high summer when I'll be producing more at 4:30am :-)
