Not the best up here either but happy enough for March.
245kWh Solaredge PV
281kWh Victron PV
518.42kWh WT1
Total 1,044kWh generated

While being a lesser month than historical March for PV, this is still a PB March due to the completed Victron PV.system and WT1. :D

A bit of an unpredictable month here, lurching from snow to brilliant sunshine then rain and heavy cloud.
I did get a high of nearly 20kWh though, a promising sign of generation to come.

The garage array shading is pretty much gone now, so as soon as there's decent sun I'm sorted.
As for the wall array, that's suffered with the clouds and rain - average daily generation was lower than February.

The unpredictable weather has caught the automated battery forecast logic out a couple of times, hence the increased export.

Nowty Towers Power Station
Main 4kW PV system generated 237 kWh which is a staggering 40% lower than baseline and the second worst March on record for me in 12 years. March is a funny old month, it can be nearly as good as midsummer or nearly as bad as midwinter.
Total PV arrays generated 608 kWh.

Electric Import was 1553 kWh.
Gas import was 23 kWh.
Out of house EV charging was 0 kWh.
Petrol used in EV hybrid was 0 kWh.
Total imported energy use 1576 kWh

Electric export was 15 kWh.
WT1 generated 597 kWh.
Total energy offset 612 kWh

Net energy use for Nowty Towers 964 kWh :evil:

2023 (to date) Net Energy Use 3239 kWh :evil:

Worst March ever for me, only installed Nov 2022 :lol: .

But compared with the PVGIS forecast, only 66% PVGIS for March, even when allowing 7% for the inverter loss on the loss free figure.

Actual = 289 kWh, 149 kWh down on the forecast I was hoping for.

Average per day = 9.3 kWh, instead of 14.1 kWh.

PVGIS (0% loss) = 471 kWh.
PVGIS (7% loss) = 438 kWh.

Let's hope April is much better, to get some significant payback on the investment.

172 kWh so roughly 100kWh adrift of the normal expectations.

Considering we seemed to spend the whole of March, bar 1 day, in the cloud base I actually think the figure we did harvest was pretty good going - certainly not as bad as I had expected based on other comments here.

Hopefully the rest of the season will be up to the task of offsetting the March losses?

I had no idea that March was so bad for some (down south?) people. It was quite wet up north - but a few good days got me over the predicted amount - 329kWh generated, vs 310 predicted.
I'm still at the stage where every month is my best and worst - until August when I'll have a complete year of data!
