Solar PV Performance Thread - Post your monthly output

championc

I think it would be very useful to post Solar PV monthly generation figures. Not only could it highlight a problem further down the road, but there many be many owners who are getting far less than they expected (or promised by an installer) and would welcome feedback from other owners.

Of course, there are so many factors involved. Your location in the country (or abroad for our international boardies), your array size, your array direction and the panels mounting angle.

Still one more day in October, maybe we'll get 1-2kwh more lol

Exactly. I didn't think I'd break 1kWh this morning, full blown storm outside. Bins scattered etc.

Looking quite nice now, generating 600w+.

And on a positive note, I should be adding 2.04 kw of panels this month along with a 5.2 kWh battery

October Stats
5.6kwp, SE, No battery, HW divert, Donegal Low angle (15 -20 degrees)

Generation : 239kWh
Solar Use(ex divert) : 114.7kWh
Divert : 79.9 kWh
Export :43.8 kWh

about 48% self consumption ex hw divert, with HW its about 80%

in the 2 fantastic weeks in sept generated 206kwh!

Notes on the HW divert:
Was set to a 400w buffer until mid oct to stop it fighting with the hob when its left on... Currently dialed back to 200w

Also now that there is a fire on constantly, HW tank never passes 60C, thus never reaching the cutoff of a hot tank as any "excess" heat is removed by the circulation pumps and sent around the house. Suppose its being used to heat the house in some fashion.

edit: Predictions
PVGIS-SARAH (Most pessimistic) Predicted 222.11 Kwh for Oct,
PVGIS-COSMO is the closest with 239.95 Kwh

Predictions for Nov
SARAH - 107kWh
COSMO - 115.63kWh

We shall see how the predictions pan out.

That 's a very high self use rate (57% excluding diversion). I presume you got a battery?

No battery, like a lot of people this year house is occupied all day and a lot of washing machine, dishwasher and dryer cycles

However I have 2 15 metre eucalyptus on the southern side that are playing havoc with my figures from about midday due to shading so I know I need to deal with those and should see some improvement to this time of the year when I do.

Based on https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html should of produced around 148 kWh for my setup but it does not take shading into account (well it can i just havn't worked out exactly how to do it) but happy all the same. was within 75% of that value.
