Renewables: "talking 'bout my generation"

Expected rain. None came, lots of cloud with sun.

4.29 O's

June finished with a precise 3 O's on the last day taking month total 3% ahead of pvgis at 138 O's.

Month totals:-

Generation 1220 kWh's PV,  220 Wind.

Import 1173 at £0.093/kWh, (June '24 12.9 kWh's)

Export 1513 at £0.15/kwh, (June '24 535 kWh's, surplus PV only)

Consumption 880.

EV's 241.

Zero Charcoal or other FF's set fire too in generation of the above.

First day of July 3.9 O's, about average for July but looking decidedly iffy so far today.

Hi CW. Just pondering that import/export (aside from the good money you make selling excess PV). I make that about £67 in arbitrage for the month, or ~£800pa*. A great way to subsidise the batts, and help time shift RE to peak demand periods.

*Maybe the monthly figure will be a bit lower in the winter, as you'll need a tad to cover PV shortfalls, but still!

Very jealous. 

Thanks Mart, I hadn't done the maths, simply preferring to wait for Octopus to do it via their statement.

I have to confess that the drive to generate and store as much energy as we can is simply born out of the desire to be as energy independent as possible, be it summer or winter. I'm not suggesting the current returns aren't very welcome, after all, there has been quite some investment to arrive here but rather that than being held to ransome via the burning of harmful fossil fuels be they from friendly or not so friendly nations. We've no desire to go off Grid as how would Ripple deliver our share of renewable wind generation without it.

Anyway, a little bird tells tells me that it won't be long before you can start joining in the fun! 

Oh, todays generation 2.49 O's...... so a few more coppers to add.

Yep, joining the fun with batts, and a PV expansion soon. Imported 3kWh so far in July. 

I think I'd missed the importance of export to people's PV investment. Perhaps being on the FiT deemed* I simply hadn't realised how much can be earned at the moment.

Visited sister on the weekend, and their PV system is nearly 2yrs old now. BiL mentioned the export payment and i had no idea how much it was, thinking they were on about 5.5p/kWh, but it's 12p/kWh. For Mch/Apr/May they got nearly £300. They should get more for Jun-Aug, and another £300(ish) for the other 6 months. So around £900pa (at the moment).

I mention this as the install was ~£8.5k (scaffolding was already in place) for 10.3kWp. So export will cover cost in 10yrs**, and I worked out the cost of generation at around 6p/kWh (including opportunity cost of capital, and a replacement inverter at year12).

Sorry for thread digression, just admitting how out of touch I was regarding export value. 

* I'm changing to Octopus export atm.
** Presumably export rates will drop, as Europe gets gas demand down, after Ukraine invasion, and if the UK expands PV rollout (eventually!!!!!!) lowering daytime export value. But you should be fine, by exporting during peak demand periods at higher rates?

I've got to ask, what's an "O"? Google is not your friend searching for a single letter.

I'm guessing some sort of normalised ratio between kWh generated (exported?) and something. Is the "something" the nominal power, for example 8.0kWh from 20 400Wp panels making one "O". Or does it account for orientation, location etc?

And whats a Maiden? 

I have got another one today!

2 O's = Bond, As in 007
3 O's = TyphOOO
4 O's = Winks, 40 winks
5 O's = Hawaii, Hawaii 5 O
6 O's = Maiden, 6 balls in an over
7 O's = Heaven, in 7th Heaven
8 O's = Potato's 8 O's sounds like Potatoes!

Here is the answer! Took a little bit of searching in google!

Oh and it’s named after forum members oscargrouch.

O is the Energy Generated divided by your installed Solar panel peak output.  
Yesterday I generated 22.9KWh off my 6.75 KW array of solar panels.  22.9/6.75 = 3.39 O's

“o” I forgot to actually explain what an O was. 🤣

4.475 O’s here on the N.E. coast.👏

It rained again. Suprise! 

2.9 Os.

Awoke to bright sunshine and that's how it stayed until after lunch when high cloud rolled in so very happy with 5.3 O's.
