Solar PV Performance Thread - Post your monthly output

With deemed export you will get paid based on the inverter size even if you don't export a single unit.

The following formula determines the Deemed Export Quantity: Deemed Export Quantity= MEC x Capacity Factor x Export Factor x Provision Interval

• MEC – This will come from the NC6 form which the customer is required to submit to ESBN.
• Capacity Factor – This is based on a calculation from the CRU and is set at 9.7%
• Export Factor – This is based on a calculation from the CRU and is set at 35%
• Provisional interval – This is a calculation used for solar installations that takes account of how Microgeneration works in practice during the day and from season to season.

In your case it would be 6.0kWp x 0.097 x 0.35 x 8760hrs = 1471 kWh x your suppliers FIT rate for a full year.

I don't want to derail the thread but the formula was on one of the suppliers web pages so I presume it's correct.

…or so I thought !!

CEG Credit is missing from this month’s bill for some reason. Never had any communication either way from my supplier SSE on any of this which is poor form.

February Generation 145.0kwh

Best Day Feb 23rd - 11.1kwh

Worst Day Feb 2nd 2.1kwh

175kwh here. 7kwp, split 4 south east, 3 north west, north county Dublin. That's versus 116kwh in Jan and 95kwh in December

First full month, 8.8kwp, south 30deg, Wicklow.

449kwh

Best day 20th 36.8kwh

Worst 11th 5.4kwh

Figures for the month of February from a 4Kw system on an even East : West split based in South Dublin. No battery. 6kW inverter:

• Total generated: 134 kWh
• Highest day:  21st 8.47kWh
• Lowest day: 7th 2.25kWh 

That’s trending up now from 78kWh in January and 57kWh in December.

SSE have clarified something. Even though I have not activated our smart meter I am apparently getting the Clean Export Guarantee of 0.24c per kWh I export. The meter says I’ve exported 250 since I had it installed so that should help with things a bit.

4.46kWp SW system on a 41 degree tilt

187.9kWh for Feb 2023

Export 54.1kWh - I have a longstanding issue with my Solis that appears to be mostly resolved only a few days ago. I expect March figures will be quite different in terms of self consumption.

Best - 13.8kWh on Feb 26th

Worst - 2kWh on Feb 11th

Just for comparison, my lowest month was December at 130kWh, and January was 170kWh. November was similar to Jan at 176kWh so that's quite a small dip.

257kwh for February. 7.2K south facing in Dublin.

First month with solar.

523kWh from a 10.4kWp system, 6kW hybrid inverter in south Dublin. Facing a few degrees off south. Two roofs, one at 30ish degrees and the other at 40.

4.55 kWp, azimuth 136°, slope 24°, 5kW, 10.9kWh, Roscommon

Looks like the last of my winter shading has gone ('till Nov). Roll on the big jump in March!

Not as good as last Feb. The high pressures seem to bring in more cloud than they used to:

Feeding in more as I got a new battery in Dec and a good night rate 😁, so load shifting without worrying about cloud cover forecast or being obsessed with self consumption (because of FIT). A good day (not perfect) of load shifting looks like this.

That translates into significant cash savings for me. Here's my estimated bill for Jan/Feb comparing my previous supplier plan with my new one:

Still worth shopping around regularly! Know your numbers

South Roscommon, 8.16Kwp, facing 210° at 35°, 9.6kWh battery

Total generation 315.2kWh (prediction at 339kWh) About a 20% drop on last February

Consumed 531.20kWh

Energy from Grid 247kWh

Energy to Grid 23kWh - 93% self use

To the Eddi 41.2kWh

To the Zappi 157.2Wh (does include night charging figure)

To the Battery 232.40kWh

From the Battery 219.5kWh

Best day 22nd with 27.7kWh

Worst day 11th with 2.9kWh

Energy exported would have generated €4.14 at Energia FIT rate if on a smart meter, we are D/N.

Felt like another dull month with only 4 days in the 20's.

February was my first full month too - 5.6kWp system produced 179kWh with a roof mounted SW orientation (215-220 degrees) in north Co. Sligo. not as stellar as some of the figures quoted above but its been so cloudy here I'm not surprised!

Still very happy with it especially as our solar generation outpaced our overall consumption for the month at 153kWh (103kWh imported from the grid). Our Feed in/grid export electricity total for the month was 134kWh. We only had our Eddi connected to new hot water tank since last weekend so expecting that we will see the total solar generation going into self use increasing substantially going forward.
