Solar PV Performance Thread - Post your monthly output

741KW generated for April up from 664KW in March. 7.2K South Facing. 142KW of April's generation went to the eddi.

6th Month

Dublin - Lucan - April 22 - 7.12kW total installed (S: 3.45kW, E: 2.41kW, W: 1.38kW). E&W Optimised. 5KWh Battery, (30 S & 22.5 E/W degree pitch).

Total Generation: 652kWh (213kWh consumed directly, 167kWh into battery, 272KWh to grid)

Best Day: April 24th - 38.0kWh

Worst Day: April 12th - 3.8kWh

Total Consumption: 462kWh (83% Solar:17% Grid (77kWh))

Milestones:

4kw shy of 2MWh generated since install last October

2nd Month Generation Exceeds Consumption

3 Days no import 15th, 21st and 24th

April 552 kWh

Best Day 09th 29.3 kWh

Worst Day 11th 6kWh

We are coming up to 1st full year since install on 07thMay21. Have generated 4617 kWh since install. We (3 adults and 2 kids) have consumed 6271 kWh. We are lucky enough to have net metering so have effectively only paid for 1654 kWh since install.

A little over €300 consumption costs (excluding standing charges) as well as a reduction on our use of oil. Significant financial and environmental benefits.

Very happy with year 1. Looking forward to expanding the system.

Very similar installation as yourself handpref (5.3Kwp here split 1.5Kwp East/3.8Kwp West) in Dublin 16. Although fairly dissimilar production graphs for the month.

Totaled 479Kwp for the month verses your 444Kwp. That's close enough that it doesn't matter a dam. It's interesting to me that you have a 5x days with more than 25Kwhr to my 2. Where are you located? Just wondering if you had any shading on the start of the month (for example a chimney that might have been reducing production which no longer was an issue later on when the sun was higher?)

There is smth not right with these figures. How can battery discharge is higher than charge?

Just did the maths on my electricity bill for the last 2 months. Generated 615kw of solar. Used 400kwh less (day usage) than the same time last year when we didn't have solar pv (Feb - April). Saved 89 euro on just the energy. Add vat and it becomes €101 saving.

Also saved 139kwh night rate which was €17 savings. I assume it's down to the heat pump drier we have.

Ohh 100% mate. Totally agree with you - they all do it though. There's a certain ambigutiy around where they are measuring.....and they could be clearer as to where the stuff goes.

Days with less than 1kWh purchased - 10

I like that stat. As in the metric itself......useful stat to know.

The reality is that every single day is a day with less than 1kwh since the inverters cannot detect with 100% accuracy the usage as they still take some time to react to the load.

It might be: Days with apparently less than 1kWh purchased - 10

Very true - although you could argue that the latency works both ways. You might be exporting a little before the inverter logs it as an export, in which case you may have "balanced" some of the import that you had delays in logging. If you follow me?

The main thing though isn't really about 0Kwhr or <1Kwhr, it's that the "number of days" figure. I like the stat, it's a good one.

For me, it's easy! Everyday I don't have enough :-)

Just completed my first full year of solar yesterday.A 2.5 kwh system facing south in Galway.

Total for the year was a respectable 2,708 kwh.

Best day was 18.9kwh.

Worst day was .6kwh

Best month was July with 339.7kwh.

Worst was December with 67.8kwh.
