Put the system details in here. https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html
Folks;
Could I cadge some real world info please. I'm looking at installing a 7.8Kw system with a 5 Kw invertor and Eddi on a due south facing roof. What would a realistic annual output look like?
The sales guy is suggesting 7281 KW annual output and figures 33% home use and 67% to grid. Is this realistic?
Thanks in advance.
4kWh . Galway, 6kW array SE/SW
That would be hard to beat I think, just under 12kwh produced from SE SW split of 7.4 In cork. Yesterday pretty much identical figures also
17.4Kwh produced today from 8.3kw array south facing
So.. Sun briefly turns into a black hole?
Jesus lads, I know it's winter, but met Eireann are reporting NEGATIVE solar radiation now - LOL.
11.3kwh in cork 👍 7.4kwh system
3.3kWh . Galway, 6kW array SE/SW
9.2 kwh Generated here in Galway. Nice surprise to see it exceed the forecasted 3.2
Nice yield.
A solid 12.4Kwh today 8.3Kw array
Home Assistant is an open source platform that runs locally on your home network, and if maintained by yourself. Pretty much any smart device can be added to it, including solar PV systems, and it allows you to both control them in one app (iOS & android) and/or web browser. It also allows you to setup automations based on the gear you use, e.g lights come on/ off at sunset/sunrise, or trigger your washing machine to start once your battery has charged from the sun.
there are loads of tutorials on YouTube on getting started. There is a bit of work involved in setting up from scratch. A Raspberry Pi might suffice if you are not a heavy user but ideally you need a home server or dedicated PC to install it on, this gives more options for running extra devices or services.
An old tablet can be repurposed as a wall display / controller and show your energy management from solar and the home in general.
There is a thread on Home Assistant on boards as well but everything you need for it can be found on YouTube
I haven’t seen anything better than 2.7kwh in Meath for the past 6 days. It’s been very poor here for me in the past week and the monthly stands at 111 kwh for a SSW facing 6.45kWp installation.
Surprisingly the east side of galway got a break in clouds for two hours so finished above forecast at 7.2kwh
No gaps up here
2.5kWh . Galway, 6kW array SE/SW
Can you give me the overview on how this works. Ie download home assistant from iOS and then where to go?
would also be great if there was a widget for iOS. But none available for fusion solar (huawei)
much appreciated
Hit 6kwh from panels today as there was a small gap in the weather in cork. From a 7.4kwh system
I had bought one of these ulanzi led clocks to use with home assistant in the past. You can send information to it from home assistant and someone created a solar generation notification which shows the current live generation. You can set it not to display solar generation when it's 0w and shows time, date etc so doesn't constantly need to show solar value. Nice to be able to see it at a glance without checking phone etc.

I managed to get a home assistant dashboard on the Google nest display. It seemed a bit flakey though.
There are a lot of us here using Home Assistant for home automation (not just for solar), and use old tablets as a display/controller.
There are a few options on it for displaying your solar PV and power usages
Examples, hourly power usage/makeup
Handy overview of power flow in the house.
Only up and running 3 days with solar. 8kwh generated. But can only get better right …besides people’s phone apps anyone using a more permanent visual overview of solar production. Like a display in the kitchen etc. may not be worth the cost but would be handy
I've a pretty similar system to yourself 2011. 6.5Kwp system split exactly E/W in South Dublin City. Here is my stats so far this month.
Note: I added 3x panels in March last year bringing me from 5.3Kwp -> 6.5Kwp, so comparing this month with this time last year isn't a like for like comparison - but the average above so far this month is just over 2.1Kwh/day.
For comparison though with Feb 2023, again where I had only 5.3Kwp, you can see the big jump upwards starting to happen.
Average last Feb (from 5.3Kwp) was nearly 6kwh/day - but it's April to Sept where it really comes into it's own. May and June last year I was averaging 25Kwh/day.
It's a little better, but not much
Shortest day is mid-ish December, so for solar, winter is Nov Dec Jan in terms of performance.
Once you get into February (spring) it really starts to stretch it's legs
May June is the best months, long days, cool(er) and sunny.
August the days are getting shorter and it's a lot warmer
https://www.boards.ie/discussion/2058050685/solar-pv-performance-thread-post-your-monthly-output
check this one out. will give you a feel for monthly stats
69.6 kWh so far for December, 6.6 kWp system E/W split.
That's an average of 2.9 kWh per day for this month. Hopefully January will be better!
Typically is January much better than December?
It will be my first January with solar PV.
Pretty pathetic at the moment, I'm on 44kwh for the entire month🤣
7.4Kw array east west Mayo
1.4kWh for me today .
11.0kWh total for last 7 days ..
happy Christmas
Grand aul stretch in d'aul yevening there tonight
Well that's the end of that phase of the solar cycle. Days are getting longer from tomorrow, albeit only seconds more than today :-)
