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.

June values for 2.48kw system, south east facing donegal.Eddi but no battery

Generation -224kWh
Grid Consumption-91kWh
Hot Water Eddi-81kWh
Lowest Daily Gen on the 28th-1kWh
Highest Daily Gen on the 1st-14.2kWh

It's interesting the difference a few hundred kms make, I am near the Old head of Kinsale, Cork and I also produced 224 kWh but my system is 2.08 kW.
I am south facing though so maybe that made the difference!

I keep everything in a spreadsheet so should be able to do a comparison v last year this week

To put that into perspective: a return transatlantic flight for one person from Dublin to New York is 1400kg, so roughly what a large solar install in Ireland produces in one year.

thats fair, but no one is flying now, so my 8 trees are 8 trees!!!!!

best plant a few aswell,

Giv Energy - why keep changing display setup..?
Does anyone know which is the figure for generation ? Why make things so complicated..

I think it’s the 547.50kwh-
5.2 system - east west split

I'd say it's Solar Consumed + Solar Exported.

See how that measures against other similar located or orientated systems on the thread.

4.1kwp mainly south facing, didn't check my monthly generation, but the last few days I have been generating 24kWh. I haven't bought any electricity from the grid in the last few days either (20kWh power wall) and I've stuck about 10kWh into my car on each day too.
