Daily pv production

Mickeroo

Only managed 0.3kwh for all of yesterday. Today should be better but not by much I reckon.

garo

Brightened up here in Dublin now. I have already exceeded yesterday's production.

DrPhilG

This morning was brighter in Donegal, but it went to crap again by half 10.

Surpassed yesterday's miserable 1.2Kwh but I'll be lucky to break 2kWh today I suspect.

Forecast says solid rain for the next 2 days too.

DrPhilG

Last 4 days:
17th - 2.3
18th - 11.2
19th - 1.2
20th - 3.0

Predicted total for October was 290kWh. On 174Kwh so far so nearly on track, but given the deteriorating weather I'm pretty sure I'll not hit 100% of the prediction for the month. Shouldn't be too bad overall. If I get 230kWh I'll be happy enough.

First full post-solar electric bill (and last one from SSE before Energia take over again) is due in 2 days.

DrPhilG

3.5kWh again yesterday. But sun on the forecast from today til Sunday.

I'm gonna launch a grenade and I mean no disrespect.
Why do people buy pv systems that produce very little power at the most demanding time of the year.

Thinking the very same myself. Loads of juice and nothing to use it during the summer. Barely enough to power a sky box from October to March.

I'm pro pv and wind turbine.
But no point fooling yourself either
I mean if u we're buying a car and the sales men told you it will barely work for 3 months of the year ...you wouldnt buy it.

Daft comparison, if you buy a car, you buy it knowing that you need it 12 months if the year, the same does not apply to solar pv, you never buy it to replace your dependence on grid power in it's entirety, that would be daft.

The same argument could be said for wind, why install.wind, when you can't rely on it when you need it most.

By the way, my pv production so far for the month of October is 270kwh, nothing to sneeze at by any means.

Have to agree on the pv aspect. It's not really suitable for ireland. A wind turbine would be more suitable for where I'm located but the cost and planning restrictions dont make it financially viable

You can’t change the sun or clouds can you? There are sophisticated programs that will tell you exactly how much you expect to produce every month in Ireland so none of this is a surprise. As far as not being able to consume what you produce in the summer: Once we get a FiT nobody will be complaining about it.
My self-consumption in May when I produced a phenomenal 767kWh was 62%. So I wouldn’t say I am not using what I produce. And now that I have an EV and a Zappi I expect that figure to be closer to 90.

DrPhilG

At the risk of getting this thread back on topic, i.e. daily production numbers...

6kWh yesterday. Today looks like a better day before slipping back into crap by Sunday.

drdidlittle

20th. 3.1
21st. 3.5
22nd. 7.0

That's all grand but how much have you spent getting setup? Panels, car, Zappi etc? How much has you electricity bills dropped by?

Plenty of discussion in the quotes threads about cost and payback time if you'd care to look.

How was he rude? You only asked, but you asked in a thread unrelated to your query so garo is suggesting that you ask in a more relevant place.

As a wise man once said, "try hard not to be offensive. Try harder not to be offended".

Apologies for going off thread.
I personally wouldn't buy something that will not work for 3 months of the year.
As for refit it'll be set very low pricewise...and pointless.turbines are similar in cold spells with no wind they're useless ..occuring at times of greater demand.
The next 3 4 months will be very interesting to see how pv works in this country.
That's my opinion doesn't mean I'm right.:)

All I wanted was a figure just to get an idea of the costs involved.

Do you have a heating system and rads etc in your house? You dont heat the house for 12 months of the year, do you?

Its a strawman argument to say that PV doesnt work for 3 months therefore its pointless for the other 9 months. Strange, is all I can say!
If it makes financial sense for 9 months then it makes financial sense.... doesnt matter if its producing nothing for 3 months.

Then I would take garo's advice and post in a relevant thread where you're more likely to get an answer.

Are you a moderator here? Very strange defensive attitude from both of you in this thread. A simple, it cost me X and I hope to have it pay for itself in X years surely can't be that difficult to tell us. You both strike me as the kind of fellas who have everything costed down to the last cent and could give those figures in a flash. Where I'd like to place panels faces wsw I'm in county Wexford so I'd probably get good output. Today would be very good sun is beaming down.

I already did give a detailed breakdown of the cost of my system, and my monthly and daily production figures.

Guess where I did so?


The cost, in the solar PV quotes thread.

The monthly generation figures, in the monthly generation thread.

The daily generation figures, here. In the daily generation thread.

How is it so difficult to grasp that you should ask your question in a relevant place to improve your chances of getting an answer?

Would you go into a thread discussing fuel economy figures for a car, and ask about how much people are paying for window wipers?

Ah ok Mr angry man. I'll probably get another torrent of bile for asking for some links to those threads as that would be too helpful. The search function isn't the best.

As the regular poster suggests. Post in the dedicated PV thread. This thread is for sharing pv statistic

garo

Been averaging around 7kWh for the past three days.
21st - 7.3
22nd - 6.8
23rd - 6.9 so far

Grid export has stopped almost completely and most days my battery is empty by 8-9pm. Lots of oven use these days.

DeclanD54

11.2kwh for today happy with that.
And my battery is at 40% soon as sun goes my battery depletes fast

Not quite done for the day, still rolling in 420w.



But looking like finishing up on 11kWh. Not bad given the run of 2s and 3s lately.

Why the next 3 or 4 months ? What not the last 12 months, or 36months ? A

Getting back on topic, I produced 18kwh today, so thays nearly 300kwh so far for October, not shabby at all.

So far this year, produced 5071kwh and exported 871, so used approx 4,200kwh, or about 700euro with if electricity

So, I posted a while back about new pv install and my lousy numbers. Finally got the installers out again (maybe ordering an additional panel helped). So they looked at the wiring and discovered that 3 of the 8 panels were wired incorrectly (pos and neg the wrong way around). So for the original 8 panels today after the re-wiring topped out just short of 2kw, where previously on the suniest days I was getting a max of 1.3kw, haven't got a figure for the 9 panels, but the weather forecast ain't great for the next while.

Good you got sorted,not great workmanship by your installer I would of eaten him out of it.

Four panel system as part of a new build in Dublin facing ESE.

Ended yesterday on 10.9kWh. Today was even better. Battery was full by lunchtime and generation at 6 by then.

Had a cloudy spell in the afternoon, but I'm at 12.8kWh now with 560w still incoming.

Electric bill arrived this morning too. €109 compared to last year's €260.

That's a nice saving. Would have been very poor here, sun only appeared just as it was setting.

5.10 kwh yesterday but much better today with 17.90 kwh

Back to earth with a bang here in Donegal.

8.7 kWh Friday 23rd

Location: North Dublin
kWP: 4.65
Split string: 2.17 kWp (SE) 2.48kWp (SW)
(My SW roof has issues with shade in winter so my figures are lower than  they could be if I had no shade!)

13.3kwh today 25th
Well pleased.

Same here, 13kWh. My daily self use rate was only 94%, that's the lowest it has been in a while

(the sunnier, the lower my self use rate)

garo

9.2 here. E/W split with a low tilt angle is starting to take its toll. First day in a few I was able to get a full battery and put some volts into the car.

The volts are always there from PV but they don't do anything for your car

garo

I dunno but volts just sounds better than watts. I think Zappi solar charging is now at an end for 4 months. Night rates FTW. Not that I am driving anywhere in the next 6 weeks.

unkel

Night rate is always FTW

I now use considerably more night rate than day rate.
