Renewables: "talking 'bout my generation"

Coastalwatch

Overcast morning with a welcome if brief short shower brightening up in the afternoon to return 3.8 O's.

Hi Everyone
I am having solar installed in a fortnight.  I do not have any previous experience so am a "solar numpty"
Can someone explain what O's means, is calculated?  And what is a "Hawaii"?
Thanks for your time.

Welcome to the board and the solar community.

The O system is a way of comparing output of PV systems on a levelized basis. Because people have differing numbers of panels of differing capacities just stating that you have produced 20kWh in a day would be a good resu8lt for a system with 3kW of panels but could probably be achievable on a gloomy day for somebody with say 10kW of panels.

So the O is calculated by dividing your total output for the day by the nominal capacity of the panels. So in my case if I produced 17kWh, with my 4.25kW array, that would be 4 Os.

The names are just a bit of fun. 5 Os = Hawaii 5-0 (you may have to be of a certain age to get that one) and so on.

6.47 O's on tuesday, 3.72 O's yesterday.  Cloudy today and not looking too good for the next couple of days either

Thanks for the explanation Netexporter.  That makes sense to be able to make fair comparisons.  And yes I am old enough to get the Hawaii joke.  Any other names used on here?

There's a guide somewhere, but from memory:

Odin (one-eyed god)

Bond (double-0)

Typhooo (the tea brand)

Wink (4-0 winks, a nap)

Hawaii (five-O)

Maiden (like in cricket)

Heaven (seventh heaven)

... and there's a name for eight, but I can't remember it!

In Yorkshire it might be a Spud - t'8-O
