Renewables: "talking 'bout my generation"

Thanks Mart, that's what I made it...4.5 kWh/kWp (although the accuracy of that is limited by the fact that my generation meter only shows whole kWh )

Wasn't/still not sure where Oscar got 4.05kWp from - that made no sense at all! :think:

So, in conclusion, the '4.05' bit is wrong and the 'kWp' bit should have been 'kWh/kWp'
That's why I was confused! :wall: :whistle:

Are we having a 'pick on Oscar' day?

Perhaps he 'accidentally' miss-typed 4.05 (instead of 4.5) to get your generation under his 4.44!!!!!!

Of course, I'm cowardly attacking him whilst bravely using you as a human shield, since my generation is slightly embarrassing at the moment.

(I suspect I'm in for at least a week of (deserved) abuse now, after my silly Tuesday morning mood. Oscar, is it too late to offer you a :beer:)

Hiya Jackie, don't worry, Oscar's just being difficult!

Nah, I'm not going to get away with that, in fact he's totally correct to adjust generation to size of install, so taking yesterday as an example:

So you can now clearly see why Oscar should be ignored!

Mart.

No more to be said apart from:-

What does'Generation per kWp' mean?

Generation per kWp is a useful measure for comparing how well systems are performing. It is found by dividing the generation (kWh) of each system by their rated peak generating capacity (kWp). The unit of measurement is kWh/kWp (kilowatt hours per kilowatt peak). kWh/kWp readings can be directly compared, despite the systems being different sizes.

Example:

URN Gen(kWh) System (kWp) kWh/kWp

X 100 4 25

Y 60 2 30

Installation X has generated more in total (100kWh), but is a bigger installation.

Installation Y has generated more per unit size of system (30kWh/kWp against 25kWh/kWp forinstallation X).

Note: You are correct Jackie, yours was 4.5kWh/kWp, please do accept my sincere apologies:o. I blame the Tortois!

Not at all!
Just clarifying that I had correctly understood the generation/system kWp calculation......
Oscar's post had me doubting myself


Hoping for another good day today...... glorious sunshine ATM, long may it last!

Rubbish forecast today - unbroken sunshine so far, not at all as forecast yesterday, that's the sort of error I like. Might beat yesterday if it holds up.

We had quite lot of fog in the morning. .. sun eventually broke through in afternoon and managed just a about 6.69kwh. YES it's KWH

KevinG

I did beat yesterday, 9.24kWh (4.62kWh/kWp). That's my best two consecutive days since 8th and 9th September!

jackieblack

10kWh generated again today!

(That'll be 4.5kWh/kWp again then )

InVestor_2

bit better today

just clicked onto 20 kWh at the end of the day

Lots of immersion,dishwasher,slow cooker, and halogen heater to soak up the excess

As ever, weather forecasst were pretty unreliable. They all agreed we'd have some early morning fog but promised it would clear up by 9am, 11am or midday. All three were wrong - it finally cleared at 2pm although we still had thin cloud cover. Having peaked at 2kW, that obviously dropped off as afternoon progressed.

But in spite of all that, we generated 7.2kWh - somewhat more than 3 x ISA 'loss'.

Tomorrow looking much the same;)

What a day!
Sun on my panels at 7.30am but, by 10.30am the freezing fog had rolled in from the River Humber.
Visibility down to 25 metres and bitterly cold.
Fog lifted (slightly) by lunch so, although I was expecting double digit output, reasonably happy with 7.3kWh:D
