Thats good. So seems on the wettest day in the Summer, good chance of 6 to 8 kWh over the day then?

Yep, I finished with 7.1 kWh.
Pennies saved, but hot water again for 3 showers and baby bath and general washing and that stopped me turning on the gas boiler and using a fossil fuel.

Install day today ... finally

Congratulations gally74. Pesky roof leak has put off D-Day for me.

Is there any good place to grab an average install cost?
Rather not have full court sales press before I know the ballpark

Or if anyone would have an idea on a south by southwest facing house in North Cork.

I would plaster that whole front roof with panels if I could!

Yeah I'm thinking that I have a good enough roof for it, and need to get it completely re-tiled, so it'll be done around then.

Need to get a view of the costs so I can even begin to shop around though.

Select a base system to use as a benchmark. One particular company has mentioned publicly a figure of 10,500 inc vat and before grant for I believe a 4kwp system with 5kwh battery, so after grant cost is 6,800. That's without an eddi, but perhaps a guideline.

The max you can go for is 6kwp (which is what I have with 18 panels), and you can add an eddi hot water diverter to that also, but obviously the costs are higher with that.

Hey folks.

Can you please recommend a make/model of a good >300W cheap PV panel and decent place to buy from?

Thanks in advance.

Being total chancer, does that grant replace the HRI grant or can they stack?

unkel

All SEAI grants can stack. In fact they give you a bonus grant for having claimed 3 or 4 of some eligible grants (can't remember the exact number and which grants apply)

Scrap that, it looks like the HRI is no longer running

Let me throw a new challenge to those of us that have PV installed and posted figures, nice numbers ,above my post.

Can we have a report with the PV production and actual usage, grid or "off-grid" so that we can see the actual VALUE of the panels production !? A figure that shows how much of the actual PV generation has been used in the house and how much not... or... how did a PV owner has adapted to suit the solar generation and availability ?

Im saying this as i got a €180 last period electricity bill...

Thanks

I have no way of monitoring what I used from the grid unfortunately.
If there’s a manual way I suppose it’s check the meter everyday at the dame time?

12 kWh produced today btw.
4.06kwh sent to immersion so full tank of hot water.
Currently generating 1.4kw as I post.

Thanks to some advice on here, namely about maxing the grants, I’m getting:

4.2 kw denim glas on glas bifocal panels 300w

Enphase micro inverters - safety and also efficiency

2 x 1.2 ac batteries enphase

My energie Eddie

Took the day off tomorrow to enjoy the setup, only racking done today

Just to add I can easily increase to 6kv when a fit comes in thanks to the micro inter s .

I went after the low hanging fruit, the base load, which is between 200 and 400 watt during daylight hours, though it's slightly higher in the evenings when I'm getting virtually nothing on solar.

As I've mains gas all heat (space/water/cooking) is from that as it's 5c per kw/h which trashes night rate electricity. If only I charge the car using it!

80kw/h gone off the electricity bill last month compared to the month before (only have solar a month) so our day/night split has improved from 48%/52% to 35%/65%. Bill should land around the €100 mark I think (fag box maths). Looking currently like a 4 year payback, but winter will be worse for solar, so probably 5 years.

Can't justify a diverter or a lithium battery when gas is 5c per kw/h. Payback is just too long.

610w in Limerick at 9.11pm this evening.
22kwh produced today with a 4.2kw east/west array.

unkel

I'm moving to Limerick

Here in west Dublin mixed weather, good bits of sunshine but also dull periods, overcast and showers. 14.5kWh produced from 3.8kwp

wexfordman2

That's my generation and usage for today.

33kwh generated
27kwh used
2kwh imported
8kwh exported
Battery charge remaining 30% so expecting it to last till after midnight.

The high usage is the eddi diverting as much excess to the immersion as it can. Booking hit water, tank filled twice today (I work from home so make use if it mid day and early evening.)

So I have been effectively off grid from about 6am this morning

Rather than heating water via the Eddi, can you prioritise charging the battery?

I'm pretty sure it does that as part of the setup. If you have Eddi and Zappi, it will prioritise direct use first, then battery, when that's full then the car, and when that's full then the Eddi (as you rightly pointed out and I've been saying for years, the value of a kWh going into immersion is only 5c/kWh)

That's what's actually happening at the moment, the battery gets charged up first, then the excess goes to the eddi.

I am told some people do the opposite, heat the water first and then charge the battery, and I can tweak the eddi settings to do that, but I think battery first is better.

The eddi and the inverter dont talk to each other, all that happens is the eddi detects a surplus going out and grabs it. That surplus only goes out once the inverter has finished charging the battery.

I can turn on or off ac charge for the battery (currently it is off, and will stay that way till winter sets in). Would be cool if I could disable DC charge of the battery as well, so for example, I could turn off DC charge between 6am and 8am, and then the excess would go straight to the eddi.

There are other ways if doing it, by tweaking the parameters on the eddi, but it is tracking so well now, I am reluctant to change it.

That would be insane. The whole idea of the battery is that you can discharge it all or mostly at the full day rate of 18c/kWh, either during the day (put kettle on while it rains) or during the evening when you have little or no solar

Heating your water is only worth 5c/kWh

And someone doing it because otherwise you'd "hurt" the battery too much (increase the number of cycles), shouldn't have got a battery in the first place

We're in a similar situation, what setup did you go for?

Yes. With an efficient condensing gas boiler. A tiny bit more expensive with oil, but a good bit more expensive if you use an inefficient gas or oil boiler or if you use solid fuel that you have to buy, etc.

Would any of you guys in the know be able to put a number on a rough price for all the parts for a system in the 3.6kw range without a battery? Trying to gauge whether it’s worth my while looking at options for not going the grant route

unkel

Rough, rough guide from the top of my head, prices from large Irish seller incl VAT

12 * 300Wp = 12*125 = 1500
Solis 3.6kW inverter 700
materials 300

So about €2.5k

Don't pin me down on a hundred here or there, just a rough guide to give you an idea

gally74

9.00 am , I'm exporting to the grid.

Panic.

Quick switch on some lights

Cant let that pesky esb get it.

Any recommendations on a brand of 300W PV panel?

Wexfordman you seem to have the most detailed monitoring information. What are you using for that please?

I hope this is good news for all those who have invested.

It's the monitoring system that comes with the givenergy inverters, link to it attached where you can view a demo. If viewing on your phone, you need to change to desktop mode. App due out soon

wexfordman2

Monitoring and being able to view how your system is performing I think is ine if the most important things in the system.

I guess there's no recommended brand then.

I am guessing that's because it's a very subjective question, like what brand of car is best, I couldn't answer that question either.

You would probably want to research warranty, degradation, aesthetics, size, power, price, there are so many variables.

Most on this thread seem to have ~300w mono 60cell Qpanels. I'm wondering what brand and where they got them from.
