Renewables: "talking 'bout my generation"

Thanks CW, but as battery problems persist I no longer have the ability to redirect the PV DC gen, so I'm seeing clipping when the 6.7kWp gen exceeds the 3.68kW inverter ..... sadly.

Leaving me in the strange psychological situation of not wanting it to be too sunny, as I'll lose out ...... but also wanting it to be really sunny to boost UK generation. Ain't I the silly billy!

Speaking of UK, quite dramatic numbers on the Nat Grid looking at the IamKate site. We have PV + wind supplying ~80% of demand, and the UK sending 3GW to mainland Europe/pumped hydro. [As of 13:39pm]

We are seeing a day of negative pricing on Agile today, but because it's sunny we can't really exploit it as we first have to "use" our 3kW of solar generation (and give up a potential 15p SEG price) before we can be paid 2-3p per kWh to import from the grid. So any usage is still really costing us 15p regardless. I have given up trying to explain that to the misses today

Friday was an amazing day for Agile pricing, the best for a long time, I was away so it was no good to me anyway, but as you say, with Solar panels and the export payments it all gets a bit complicated. Today is also pretty good with very low rates and some negative this afternoon.

Agreed. I only had my panels installed and SEG set up recently, so I'm still trying to get my head around the dynamics of cheap Agile pricing during peak solar periods. Generally I think our real terms price is capped at the SEG export rate of 15p, unless we can exceed our generation and import heavily. So yesterday we were trying to combine heavy usage into negative slots and hope they were cloudy!  IOW, if we have to import, lets import as much as possible by concentrating usage.

Bit of a dull start, but sunny afternoon, so got 3.18 Os.

Haven't a clue what was generated for the last two days as at 11.30 am the day before there was a power cut, since when all generation or reporting of it has ceased. On the plus side, power is at least on at home and the Giv batts are 98% SOC!

3.8 O’s here.😀

4.8 O's here, after a poor start the afternoon turned out sunny. 10 days in and we are above (pro-rata) PVGIS for the month. Tomorrow looks set to be another decent day.

Nice day but spoiled by afternoon clouds.

Perfect curve, as good as it can get with the warm temperature 5.94 O's

5.31 Os today. Not a perfect curve though, bit up and down around the middle of the day.

Sunny day. Distorted curve during the morning, perfect curve from 13:30
