Domestic Solar PV Quotes 2022 - No PM requests - See Mod note post #1

Yup. I got a quote, but not had a follow up to my questions. Guessing they are too busy for their own good

I think they do, but as much as I champion their work and prices, I personally wouldn't want an install from a company quite that far away.

Any follow up needed and you'll be a long oul drive for support.

I had no big issues but did need a wee configuration adjustment with CT clamps etc. He was with me within a few days. Doubt it would have been so fast if I was in Cork. Its just not practical.

I’m in Cork. Could I get some recommendations for reliable installers please?

Hi, thats great :)

Those panels - are they 400w panels?

And what size hot water cylinder do you have?

Any plans to get batteries added in the future?

Sent there.

Just bear in mind that if the EV is on the driveway 90% of the time, if you fill the battery on Monday.....are you going to drive 50Km on Monday night/Tuesday morning to make space (10Kwhr) for surplus on Tuesday? It's certainly not an easy question to answer, but my gut feeling is that most houses with an EV would be well suited for a 5kwhr battery.

Well done on the install btw, good price too!

All the Cork gang are on the scene it seems!

@MAULBROOK I would really appreciate the details of the Cork supplier also if it’s not too much trouble, thank you!

With regard to some of the PV install Battery quotes ie 5kw. Are they AC or DC batteries ?

Thanks, I suppose the reason im asking is I've ordered a PV system with a 5k Pure Drive battery. I looked at the Pure Drive website and they said their AC Batteries could charge at night rate using their smart technology and utilise during the day when the kph usage is more expensive. I didn't say their DC batteries could do the same.

Ah brilliant stuff, Thanks for the detailed response Ha Long Bay,

I am getting a 5 KW SOLIS HYBRID INVERTER. This is prob another little benefit that doesn't seem to be talked about that much.

Probably better suited to the "Solar Batteries Options. (Solar PV battery options - Page 66 — boards.ie - Now Ye're Talkin')

As regular readers will know, I'm fairly positive on batteries......but with the proviso that you need to do your math. I assume hick that if you are talking about Pylontec then you are talking about off the shelf? The problem with large off the shelf batteries is that it's a fairly significant outlay. 15kwhr in batteries is going to be €5000-6000? More? With a 5kwp in panels and the loads that you have, I would think that you'll struggle to fill 15Kwhr off solar. 10kwhr might be doable, but not sure you'll have the surplus to fill that, esp if you have an EV in the mix, or if you fill the battery for the house use, then there won't be anything going into the EV. I'd be looking at upgrading to 8-9Kwp in panels for a 15kwhr battery as they are all interconnected.

Now of course you might be thinking of load smoothing (filling it at night rate for day time use) and while that does generate money, you need to be careful with the math. I generate €1/day during winter on 8.2Kwhr, but I've a consistent load (mining) and that doesn't change. With a heat pump, you probably won't use much during summer, and again....the math may not work out for you.

If at all possible, a DIY battery would be the way to go. I know that is daunting for some (incl myself), but I think it's worth at least investigation.

HI Folks - quotes just in from a local installer here in West Cork

1) 8 x Longi panel (3kW), eddi, no battery €7637 - grant 2100 = 5537

2) 8 x Longi panel (3kW), eddi, 3.6 battery €11372 - grant 2100 = 9272

3) 12 x Longi panel (4.5kW), eddi, no battery € 9092 - grant 2400 = 6629

4) 12 x Longi panel (4.5kW), eddi, 3.6 battery €12644 - grant 2400 = 10244

All plus €1k for scaffolding + BER Assessment for SEAI grant

All figures inclusive of VAT.

House is small 3-bed detached, built 2004, south-facing roof, ground-source heat-pump, two adults home all day.

Which system sounds more suitable for us, and comments on the cost, please?

Thanks!

Option 4 is probably the best for your needs, option 3 is the least poorly priced, but they're all pretty expensive. Adding the scaffolding cost separately is a bit weird.

Thanks for the reply both

yes my plan is top up battery with solar. I reckon I can get about 6.5kW up on the roof with my config. Would look at optimisers too for final quote to ensure I’m getting the best from the panels.

I need to be able to ensure I can top battery up first. Then car. I’m not so worried about outages, a least long term ones (going to put a generator shunt in when we are doing install for fun).

I reckon you’re right, will start off with 10kW and can add in more later.

mu main focus is to drop the reliance on pulling from the grid and when I do, to be leveraging the cheapest rate available!
