Renewables: "talking 'bout my generation"

jackieblack

Last day of FIT quarter yesterday.
Was surprised to discover that quarterly generation (701kWh) fell only a handful of kWh short of the same quarter in 2011 (sometimes known as 'the glorious spring of 2011' ) when we generated709 kWh.

Can't say it's felt much like it , but just shows these things can be deceptive, I guess :huh:

Hi

Would that be SI units or derived SI units (joules), or units derived from derived SI units (watts), or units derived from derived derived SI units (kWh) or, in the case of a unit to represent kWh/kWp, units derived from derived derived derived SI units (with a slight caveat) ....

.... perhaps the answer is to simply use base SI units, therefore our system performance for yesterday was ~3.3 kg⋅m2⋅s−2/kg⋅m2⋅s−3p ....

... note though, the addition of the p (peak) suffix to denote the nominal/nameplate capacity of the array isn't strictly allowed within SI .... .... so, unless we want to use full descriptive text in lieu of p, we might as well scrub the idea of pure SI units & do what everyone else does - simply derive to kWh/kWp.

HTH ....

28.23 kwh today, a new record for me not bad for May :j

7.1 O's :rotfl:

Immersun waiting in the garage to be installed to capture all that exported Leccy

(It's mine I tell you, mine, mine, all mine:mad:)

Nice one but unless you've got a humungous hot water cylinder or keep the hot tap running you are unlikely to use more than a third of that!

Bitterly cold, dull morning, Sun only appearing at 12.00. Stayed out until 18.00 so ended today with 4.55 O's or 18.2 kWh:T

If weather is as promised for tomorrow, could still hit 1MW for the quarter:beer:

8.51kWh / 2.12 O's - very dull and cloudy day that eventually cleared slowly mid-afternoon and around 6pm the skies almost fully cleared.
Think the panels got a good clean today with the torrential downpour that happened in the afternoon

Tut, tut, even you are misusing O's now - that's kW/kWp, not kWh/kWp

"My peak has hit 3.246 kW before now; not bad for a 2.5 kWp system: not wishing to steal your thunder......that would equate to 5.193.6 kW if it were a 4kWp system"

Better? or must try harder......???

Quite so ! I'm sure Groovyf was referring to his peak generation in kW which (perhaps not surprisingly) was capped at the limit set by his inverter. That has nothing to do with his daily output in kWh and even less to do with any imaginary units that many find confusing.


There are quite enough units defined in the SI scheme without adding new ones.

Chill Eric, chill......

Anyway, enough of this banter, some have no sense of humour, how boring this thread would be if everyone just posted 12kWh, 16kWh, 28.23kWh.........I will take the 28.23 one @ 11.292 O's ! Please, please, pleease; double Hawaii + 1.292 O's; is that allowed Mart ?

4.24 O's today...hmmm let me just check.........mmmmmm yes; that seems PC okay.......

Looks like a great day today. So far almost exactly on par with my best ever day, but hopefully a less cloudy afternoon!

Here's a comparison - PVOutput is really cool!

It's sunny here where I work... so a few miles back up the road to home should be the same... No idea what my system is up to! I *need* some remote reporting!! I believe I can get a wi-fi add-in card for my Aurora inverter now - released a month or two ago.

Only just spotted the ability to compare days... how cool!

Tell me about it, I'll just have to wait for battery storage to be viable now - done everything else i think i can do

I wonder if next door want some to buy off me..........
