Solar panel production figures

scores on the doors for me... 24.2 with 19kwh exported

I'll take that and double it, on both counts :D

48.75kWh generated and circa 42kWh exported, new records on both counts.

It's just starting to get legs, only a matter of time before I join the 50's club, today had a lot of intermittent clouds.

Interesting facts, the voltage started increasing on the Victron array at 4:30 this morning, it was 5:30 when it started generating power, 6:30 the SolarEdge system kicked in, by just gone 7am we had 1kW of PV power, 18:30 we dropped under 1kW, and currently we still have 115w of power. Total generation time today was just over 14 hours.

GE Inverter talks to Octopus API and works it out, pretty clever, nice at a glance stats. I combined them into one pic for the forum but typically shows them seperately.

Nice, I'm still waiting for the Octopus Watch App* to update yesterdays export. One day I'll get the Victron system or HA to talk to Octopus via the API, it can then download all my data.

Here's my graph for today, I got the crayon's out and coloured it in.

*Actually it just updated, -£4.79 for yesterday.

very nice..... I would love a bigger system. my father in law has just had a nice one installed..... 50% larger than mine..... but a lot more expensive.
for £8350 installed i am happy with what I got (but could always use more ;) )

My additional system was a self install, with electrician doing the AC work, costs certainly got a lot higher than I expected, hopefully with Flux I'll still turn in a decent ROI time, but not too fussed.

I asked Octopus whether there will be any retrospective payment for my free export while I've been on FLUX - they were somewhat evasive, saying that it was a system issue that doesn't allow them retrospectively to calculate the ToU earnings, not having an export MPAN number to work with. However, I've seen posts here and elsewhere saying that Octopus have paid some people for their exported kWh since they first signed up to FLUX.

I'm pretty sure you'll find back dated Flux exports only apply to people that were already getting paid for exports by Octopus.

Hi, I’ve recently moved house. Already has Sola panels.they were installed back in 2014.

Previous vendors where with EDF and signed up with them as there isn’t much out there. Hopefully things will change soon.
Do I need to inform EDF that I have sola panels. I just don’t know where to start.

Any help would be appreciated.

You need to get the FITS payments transferred to you, this should have been dealt with alongside the house purchase.

I also paid for the system outright, so no loans or zero interest credit cards

Ditto, although I do have a zero percent card with the money suitably invested elsewhere to cover it should I need to I didn't use it for my solar install. Used savings, and mainly paid for it as I went along (very small mortgage as I'm mid 50's and over paid it), one benefit of it taking over six months to come to fruition.

Looking at your pvout you've had a pretty awesome April for generation, even ignoring the larger panels and such!
Click to expand...

I've just looked at the full information on the SOlarEdge web dashboard for April.

2016 513 kWh
2017 562 kWh
2018 423 kWh
2019 492 kWh
2020 570 kWh
2021 550 kWh
2022 553 kWh
2023 481 kWh (Projected currently at 418)

So 2018 was the worst at 423, this year looks to be the second worst.

The Average is 518, so we are below average.
 
@MassiveJim Put as many panels on as you can, and perhaps double up on the batteries. Just make sure you get an MCS certificate, you can then get good export payments on Octopus Flux. I aim to fully charge my battery as much as possible off peak at 20p a kWh, then excess is exported at 23p, in the winter you need the battery to last through to the next cheap rate period to charge again. I've even export some from the batteries in the peak period at 36p kWh.

As for costs, and ROI I've no idea, but my electric bill is -£18 most weeks although only been on the new tariff since 11 April, and that's only going to improve as we go into summer.
 
Today's figures are 33.61 kWh generated and circa 28 to the grid, some Welsh clouds came along so the afternoon wasn't as good.

Ron-ski will be pulling even crazier numbers.

@MassiveJim My electricity costs for yesterday were minus £7.03, that means Octopus credit my account £7.03 for just yesterday.

Yesterday I imported just over 14 kWh, this was between 2am and 5am when I pay 20.51p per kWh, then I run off the battery until the sun comes up, charges the battery until full then export the excess over and above what we are using for 23.18p per kWh. I exported just under 40 kWh, and roughly 10 kWh of that was during the peak rate 16:00 to 19:00 slot, earning 36.85p per kWh, some will be from solar, and some force discharged from the battery.

On Flux, due to the good export rates it makes sense in most cases to charge the battery as much as possible in the cheap rate period, that way if the day is bad you have plenty in the battery, if the day is good then you export for more than you imported although there will be some efficiency losses, this also makes managing it all very straight forward.
