First day with all panels connected. Total 6.45KWh now. 12.2KW produced
Happy with that for the time of year I think. Pity that I'm exporting so much with no FIT yet.
How many KW installed please?
I get my terminology mixed up. 15x 430 Jinko panels so 6.45KW in total. I had 10 installed initially but they said that they could get another 5 up there so they came back and added them. I do see that the newer panels are a little less efficient in the afternoon due to shading from the low sun angles but they should be much better for most of the year.
8.4 KW Array south facing with a 9.6KW Battery, system just went live on the 10th, production by date:
10th-22.1KWh
11th- 11.1KWh
12th- 17.6KWh
13th- 20KWh
14th- 22.3Kwh
15th- 21.1KWh
south facing systems really do beat all in the winter months
Only the ones with absolutely no tall trees or buildings within 1000 meters, south.
1000m? How tall are the trees around you?
10m sure, maybe 20, but 1km?.🙄
I would say close to 100m
My lower string diffuse (not visible to the eye) shading had started.
The sun gets lower for quite a while before it impacts the upper string. The trees past south will have an impact soon, and that are more than 75m away
They are not south facing
@AmpMan, true (sse) but the shadow length is down to the angle of the sun. The principle holds.
Shortest day of year has peak angle at just over 13 degrees.
Not even sse. SE
I've a question, I hope that's ok for this thread.
Today was my first full day having my solar install.
Is 1.9kw production about right from a 4.3kw array on an overcast day like today? The array is SE facing in South Dublin.
Given the sun never really got out I'm assuming 1.9kw is about right for a day like today.
That's roughly what I got today from 4.2kwp. Very dull here in Cork today.
A whopping 1.7kWh (from 6.84kW array).
Well into the hungry gap now, to steal a phrase from food growers.
In the doldrums now until around the end of January.
4.5kWh from a 11.6kW array😑
I only did 1.3kwh today with a 7.5kwp system. So you did better than me.
I said within. And most places are hilly.
Was a good day today and pulled in 20.1 kWh, It was aperfect day almost but thenclouds rolled in 3pm and it was like someone turned the lights off...
November is going to be alright as well already well over last year and might hit 350 kWh, Thursday is looking great for the end of the month
Nice, that's a decent summers day for me.
225kwh here so far. The start of the month was good for me.
Hi all,
Been reading back through few pages and finding it hard to calculate true yearly usage for the following;
4.8KW, south-east facing Dublin
Anybody got an actual full year kWh generated figure? (Not a random day times 365, an actual full year figure)
Thanks
I’m sure that people from your area will be able to give some ballpark figures that you can expect but what I have found in my limited time with the panels is that so many variables play into the calculation that every installation will differ. You have roof angle, panel efficiency, orientation, shading and the biggest variable is the actual weather. So you could get 10 different answers from the exact same installation for 10 different years with weather alone.
It's been often said but
the EU jrc data base

Use the default settings, put in your angle and alope and it gets you really close to the mark.
Some months you may beat it, some months you won't, it all comes out in the wash anyway
My daily production is really poor at the moment, it may not even be covering the electricity usage of the inverter 🤔
yep... im averaging id say 2 or 3kwh per day generation.. tomorrow looks a bit better at 6kwh forecast.. east west drop off big time in the winter months.. especially south east/north west.. in the summer my system can do 45kwh a day..
I look forward to those times, I've only recently had them installed and while October was decent November is just less than half 😕
How are you forecasting tomorrow's generation?
I use the solcast website and API with home assistant integration. You can configure your solar arrays and location, size etc and it does a reasonable job
Nov, Dec and Jan are muck. Here's my last 11 months and Dec will be 5 time lower than our savage June + July. Ours is a 4.9kWp system. E/W so has lower output than S. Ignore the kWh's below but you can see the relative % change over the year.
It leapssssssss up from mid March
