Wow these O`s really rile some people
I wonder in what simple way these doom-gloomers would compare totally different systems?
It`s a simple way for us simple people to compare generation.
Leave the simpletons alone.
Personally, I have never understood people's need to compare their system with everyone else's whether it be by overall kWh generated, kWh/kWp or even by the pounds sterling beloved by one particular poster, but each to their own.
However, if you simply have to do a comparison then why not compare your own system's generation against the PVGIS climate database for your location and post a percentage? In that way all variables are taken into account.
For example, during April, according to PVGIS, I should have an average daily electricity production of 4.75 kWh. Yesterday my system generated 5 kWh so my percentage would be 5 divided by 4.75 multiplied by 100 = 105.26%.
You could call it a TGH if you wish.0 -

Quite so ! Tunnel can compare his individual systems but nobody else can derive a meaningful relationship with their own system.Martyn1981 wrote: »If you don't like kWh/kWp (O) then don't use it, what's the problem, nobody is forcing anyone, it's all supposed to be a bit of fun, but for some reason the anti-O's keep moaning!

The 'problem' is that readers of this column have been deceived into thinking that this ratio might be all that anyone else needs to compare with their own system and consequently don't bother to give the data which is actually needed to make such a comparison.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -

I think, you are perhaps not giving due credit to other readers to work out for themselves how they choose to post.
Come the end of day, as Mart stated earlier, this is only supposed to be a novelty. I must say, I do enjoy the odd 'eruption' now and then.......:rotfl: :rotfl:2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.

Think I'm in with Shavy as well, nowt better than kWh/kWp (O's) :eek:2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.

Had a whopping (for me) 15.4kWh yesterday - seems my early morning post suggesting the weather would be good all day proved in my favour
Today, however, couldn't be more different... damned blanket of cloud.4kWp system (Feb 2014) : 1.5 SW, 2.5 NE (16x Bisol BMO/250, Aurora Power-One UNO PVI-3.6 Inverter : pvoutput.org/list.jsp?id=299350 -

...and a paltry 4kWh today!
Also, this must be the 4th evening in the past 7 days where the clouds have fully cleared just as the sun sets...4kWp system (Feb 2014) : 1.5 SW, 2.5 NE (16x Bisol BMO/250, Aurora Power-One UNO PVI-3.6 Inverter : pvoutput.org/list.jsp?id=299350
