Glad it's been muck for everyone in a weird way. Ours is finally live this week and the output has been muck. But so has weather. Was spooked to tell my other half we hadn't hit on the 'perpetual free energy system' I'd promised her from the bank loan we took out :)

Though on the flip side I'm amazed a day as crap as today (in Dublin at least) still gave 8.5kwh on our 4.9kwp setup (E, S, W split). Raining for maybe half the hours of sunlight. Now I know where the bottom of the barrel is for a wet July day.

Tell me about it...

I've been convincing myself that my new 6kW inverter is somehow less efficient because the numbers have been crap since it went in. So it's a comfort that everyone else is having a crappy time too lol.

Seems hard to believe that I managed 50kWh in a day in early June.

May has been my best month for the 2 yrs I've been running, after June well, it might as well be winter 😂

In 2021 July actually beat June by about 20kWh, so roughly the same daily average but with an extra day in July.

This year June had 809kWh and dropped to 610kWh for July.

Looking forward to May 2023 to see how I get on with the bigger system.

8kWh after a rotten day and the worst for a considerable time, just about got the battery charged. Haven't seen much of the sun for the height of summer...

On the plus side batteries are on the high seas so should be hitting Dublin port by the end is August, delayed 4-6 weeks for various reasons like everything these days. No wonder those in the install game are waiting so long to get stuff.

slave1 · 31-07-2022 12:46pm

This Summer well down on last Summer, 12% less

yankinlk · 31-07-2022 6:08pm

Today surpassed June by 5+ but down 30 from May. 6.5 tipp ew.

deravarra · 01-08-2022 6:57pm

Despite all the gloom about how much solar pv is pumping out rn, i'm still delighted to see that even in the middle of a horrible day, I will still have enough to keep the house off the grid for most if not all daylight hours. That is not a bad thing.

DrPhilG · 01-08-2022 7:03pm

Today started well but descended into this by lunchtime...

!

Generation dropped as low as 300w but recovered a bit, to around 600w.

Battery currently at 70%, I'll probably just about make it to morning without import.

Spot on!

SD_DRACULA · 02-08-2022 7:43pm

Today started off quite poorly but picked up in the afternoon, ended with 26.5kwh

Due to the poor weather the other day the battery was at 20% in the morning and just about managed to get it to 100%

Jonathan · 02-08-2022 7:52pm

As SD said, turned out to be an unexpectedly day. EV was down to 3% after a long journey yesterday. So put in 10kWh from grid as a precaution. Could have done without has i known weather was to be so nice; managed to divert 10.45kWh of sunshine today.

Ah well. The grid was relatively green at the time and it only cost me 70c.

Gerry · 02-08-2022 9:42pm

13.6kw today, 10 exported. could have been better if I was at home.

can anyone recommend a wifi smart plug? thanks

I have Sonoff plugs and Meross plugs and bulbs both are ok but can be buggy after power cuts. Whichever you go with stick to the same brand, makes it much easier.

I've a TP Link Kasa KP115 and very good. You can set it for local use only, and there's also an integration in homeassistant. I've used the same one for everything from alerts on the coffee maker to automating a lamp, and now using it to monitor the mechanical ventilation system power. I need to buy a few more.

silver_sky · 02-08-2022 11:20pm

I charged the battery from grid to 80% last night as it was down near 20% at midnight. I was expecting a similar-ish poor day today. End result was 22.7kWh generated with 83% self use. Eddi took 5kWh and Zappi managed about 9.5kWh.

Temperature worked out OK also, I think the breeze may have helped so no apparent derating. Generation peaked at about 4.9kWp on what is a 4.46kWp system.

Can recommend the Kasa KP105/115s also, but alas they are no longer being produced in UK socket variants any more in favour of the inferior Tapo line. For that reason, I'd go with @con747's recommendation.

Gerry · 03-08-2022 9:52pm

thanks for recommendations on smart plugs.

DC999 · 03-08-2022 10:16pm

Finally.... a decent day for me to post my 1st good output. 20.7kwh on 4.9kwp (E, S,W). Dublin 12. Tis live 1 week now.

Having 3 roof orientations gives us a good spread from early to late. But with that we rarely get high kw output (which is fine as don't need it). Have optimisers on 5 panels that get shaded and seeing huge differences in output at (rare times). So they do seem to be helping. More on that again when I have more data on them.

Most going back to grid and still at ladybird stage learning how to consume when available. No automation yet but will in time for sure. The backwards spinning meter means that's all good thougb while I learn :)

Little we can use to mop it up when EV not in the driveway. Our house runs on maybe 200 or 300 watts for a lot of the day. Don't wanna start using tumble dryer (don't need in summer) or stuff just to use units.

deravarra · 04-08-2022 8:26pm

12 generated yesterday - and today was a whopping 25.3. At one stage I myenergi was showing something like 5kw being generated - from a 4.4kwp system with 2 x 3kw inverters.

despite having the dhw sorted and 2 x loads of washing, some drying and the lunch ... I still exported 14.5 kwh to the grid.

Bakka · 04-08-2022 9:37pm

The last couple of days have been brutal for generation. Today was a great day. 52Kwh in sunny Galway. 9.1 ground mount system.

DC999 · 04-08-2022 10:47pm

Jaysus @Bakka, I thought my new 4.9kwp system in Dublin was baitin' along today on 22kwh. I was nearly telling random strangers about the power of solar. Now I shall cover my solar panels with my very own shame

Bakka · 05-08-2022 1:31am

Ha Ha. The ground mounted system catches the sun most of the day. I'm lucky that I have the space for it. You still had a good output for the system you have. With the way electricity prices are going through the roof, we'll be both grateful for every single kwh generated. Solar panel systems are also going through the roof pricewise. My system is new as well. Only one month live. Just let the sun shine down for us.🌞

DrPhilG · 06-08-2022 11:13am

17 day units used

92 night units (had to stick 50 in the car the other night)

Expecting about €80 total bill for 2 months and I'm €550 in credit.

I'll enjoy it while it lasts. They've already hiked my prices to 28c day and 16c night which is scandalous but I'm not moving til I've used the credit unless they'll agree to send me a cheque, which I doubt.

slave1 · 06-08-2022 12:18pm

They will refund if you leave, they have to

https://www.boards.ie/discussion/comment/119436426#Comment_119436426

And I assume this is before any FiT credit too ?

I could be in a similar boat - I'm about €230 in credit and with EI and my NC6 is filed at 6kW, and my contract is up in January

DrPhilG · 07-08-2022 12:29am

3 fine days.

Thursday - 29.7

Friday - 35.2

Saturday - 27.8

Downside is that I exported 17.2kWh of it.

Bobeagleburger · 07-08-2022 12:56am

The forecast for next week looks good

ECO_Mental · 07-08-2022 9:07am

Gona be a gud wan today...
