Domestic Solar PV Quotes 2024 - No PM requests - See Mod note post #1

Would a quote post grant €5k for 3.6kw system with diverter be about right? Obviously no battery.

Wondering what peoples thoughts are on the below options, all include the BER, prices are before the grant. I have frequent enough outages so want changeover option to use solar/battery when available and generator when not. Probably leaning more towards 2 or 3 since they are modular and thus only one manufacturer to deal with for warranty.
1) Solis / Dyness with 20kWh batteries (€15,000)
20 x Jinko 440W panels
Solis 5kW hybrid inverter
2 x Dyness Powerbox G2 10.24 kWh batteries (additional battery €2,500)
Manual Changeover Switch
Generator Plug
I have another Solis / Dyness quote with 4 x DL5.0c (20kWh) for €12,800 but they don't do changeover and I want the Powerbox G2 as installing outside

2) Alpha ESS system with 20kWh batteries (€15,750)
20 x Jinko 440W panels
Alpha ESS Smile G3 5kW inverter
2 x 10kWh Alpha ESS batteries (additional battery €2,500)
Manual Changeover Switch
Generator Plug

3) Sigenergy system with 16kWh batteries (€15,300)
20 x Aiko 445W panels
SigenStor 5kW hybrid inverter
2 x 8kWh SigenStor battery (additional battery €2,450)
Automatic Gateway HomeMax (for install later once approved)
Generator Plug

Fancy PMing me who your #3 is from? Was it an itemised quote?

Unless they lost the status they were Tier 1.

IMO, quote 1 is decent and I'd jump on that

What's a 'Battery changeover socket'? I

Got two recent quotes. Best of them is the following:

€6500 [price before any grant applied]

5kw Solis hybrid inverter

12 x panels 445w Hausun glass glass panels

Extra panels 300 each

What do people think? Seems good?

Got this installed last week on shallow pitch barn roof

24 x 440W bifacial glass/glass, TW Manufacturer brand, 12 oriented E & 12 W, 10.56 kWp

Really? Shiite. And that was the cheapest of the three quotes I got.

I presume that €5000 is after the grant is removed, so €6,800 is a good price for a 4kw system, have a quote of €7300 for a 10 panel 4.6kw, no water divider, hybrid inverter and 8 optimisers. Longi tier 1 460w panels

Friend just got a quote; am not as up to date as I was last year. Interested in views

11 Panels 435 watt Jinko

3 Optimisers

Solis Hybrid Inverter

BER included

Total €7,500 less grant of €1,800 which would make it €5,700

Can you comment please on this quote . I’m looking for ground mount . It does seem roof mount is preferred by most suppliers .

8.9kW Solar system with 15.36kWh battery storage ( after grant  €11,999)

This comprises of

-) 20 by JA Solar 4.0 Pro JAM54D41-445/LB/1500V (445W

-) 1 Hybrid inverter Solis S5-EH1P5K-L (5.5kW)

-) 3 by 5 kw batteries Dyness DL5.0C (5.12kWh / 4.61kWh usable)

-) Installation and ber assessment

as it’s ground mount I haven’t seen what the ground mount options but will check this out .

Your thoughts please .

I didn't even pay deposit. Never pay all up front. If any issues after few days they won't come back if all paid up.

What did the contract or quotation say about payment terms?

This is what I've agreed with my installer.
