My brothers been keeping records since 2018 when his mostly E/W array was installed. This May was 85% of the previous worst May and 75% of the average (and 65% of the best which was 2020). So its not that your last May was exceptional, but that this year was exceptional, except in a bad way. Hopefully next May will revert to the mean, though so far June is running worse than May for me on a day for day basis, which is bad when you consider it should be better.
But the PVGIS expected generation is what I'm comparing against and that suggests that our May was basically as expected. Last year really was exceptional. Other folks may have had a worse than average May but we did ok.
It's worked pretty well for us, so far, so no complaints. West is actually particularly good for benefiting from export tariffs like Flux when you have a peak in the early evening.
The big advantage of east/west is that you get a long steady solar generation day compared to a south array that will have a higher peak output but for a much shorter period of time. We have East West and and start generating around 4:30, finishing about 9pm!
The Fondant Fancy solar output shape looks much better for the larger array where deliberately oversizing PV to inverter and perhaps dealing with a DNO imposed export limit. Would be interesting to see the same output curve on a sunny midwinter and spring day. I suppose that could easily be modelled in the PV tool demonstrated recently. We should consider ourselves lucky facing due south but dealing with the midday theoretical max peak output is a challenge if we were to triple the size of our 3.68kw array.
Thanks Tim, well your E W array easy out performs my South facing array. In fact May was cloudy up here in central Scotland so it not surprising . So my 5.1 kWp south facing array produced 573 kWh . Compare that to April at 504kWh its not as much of an increase as I was expecting . On the plus side we were in paid for export £43 so a negative bill for May. As I have said previously we have moved from Agile to Intelligent Go and as usual my Octopus app no longer shows weekly or monthly usage , it always seems changing tariff causes the app to faulter.
We seem to have done relatively better than a lot of people in May, for some reason. I guess we got lucky. Still, getting a negative bill is always nice!
Coming to the end of autumn here in Adelaide, South Australia. Been quite dry this May so solar generation has been quite good. Generated just over 1 mwh for the month. Generated 579 kwh from the 6.3 kw north facing panels on the house and 506 kw from the 6.5 kw east west panels on the shed. Total generation is 1.08 mwh.
@@Ryanhothersall I've not discounted it entirely, although it might take longer than I originally hoped, depending on how panel prices change over the next couple of years. The North facing roof might become viable eventually. Hopefully!
As always I came for the Solar stuff and ended up watching a football video. That has messed with my head. 🤪I honestly thought Tim would be buried in a secret government bunker working out how many pencils the civil service get through. Tim, thanks as always for sharing your knowledge and promoting green technology.
You’ve persuaded me to take the plunge with IOF instead of Agile as I have a much higher generation than consumption. Submitted my application a couple of days ago but it failed at the GivEnergy enrolment - have messaged Octopus and am awaiting their reply. We generated 1400kWh in May with 530kWh of home consumption for a -£135 consumption bill. Interesting that our hot water heating is less than half yours, 53kWh for the entire month - the ASHP is much more efficient than the immersion heater.
I had the same problem signing up to IOF and it took a couple of weeks for Octopus to get back to me (although I didn't chase them after the initial email as I decided regular Flux was fine for a month). I hope they're able to sort you out soon.
oh I didn't know you could see individual strings in the inverter web interface. I'll have to have a dig. I finally got my SEG switched on after being stuck on FIT for ages so I'll keep an eye on your results for the summer with intelligent flux - looks interesting
@@TimAndKatsGreenWalk indeed and it will mean that we get less next month when the price goes down. Strangely we benefit more the higher the price of electricity is and others suffer more
Hi Tim, thanks as always for your informative videos. I’m interested in switching from octopus Flux which I’ve been on for a year, to intelligent octopus flux. I currently enjoy exporting to the grid and have all GivEnergy products, 5wK hybrid inverter, qty3 9.5kW batteries and GivEnergy EV charger for My Renault Zoe GT EV (50kW with rapid charge option) . I’m finding it difficult to decide to switch to intelligent Flux . I notice on their FAQ that they say they on support 1 battery, do you think that applies to me as my 3 batteries are all linked together? I would value your opinion.
It's really the number of inverters that's important, not the number of batteries. If all the batteries are connected to the same inverter then that's fine. I have two batteries connected to my inverter and it's treated as one large battery. By the way, did you see my video about how to choose the best tariff for you? You might find that Intelligent Flux is not great for the Winter, so you'd be better off switching to Go or Intelligent Go at some point, depending on how much generation and consumption you have: ua-cam.com/video/xz8XRwHcgC4/v-deo.htmlsi=NPojgXcnP1_n3eQc

Been curious about East West generation for a while as opposed to purely south, and there it was. Great, keep it up!

7.38kWp ground mounted south facing solar array. Octopus Flux tariff. Production 962.7 kWhs Consumption 230.38 kWhs Export 721.01 kWhs Import 6.04kWhs. From Octopus bill credit £134.80 - £1.78 import - £19.22 standing charge = £113.80cr
That's great!
We have a similar generation and use as you. Our 19th May generation curve is probably the most perfect I've ever seen...
Nice. Spoiler for the next video, but our June 2nd was even better.
Hahaha sorry, that's a very geeky sentence showing mucho love for your solar. Love it!

One day I'll add more panels and then I might finally breach 1 MWh in a month. One day.
@@TimAndKatsGreenWalk I saw your video about adding more solar. It’s a shame it’s not practical for you.

Yeah, there's a lot of stuff hidden away in the web portal. Takes a bit of digging to find it, mind.
Also for the compassion on the May bill from last year remember that the price was higher for electricity compared to this year
Yes, true, that did contribute.
