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

Had the K£ lads out today dropping off some stuff, and from their review of the roof they think I'll only get 5 on the front and 4 on the back in my E/W array.

When xxx was out in April to review and give me s quote, he looked at the roof and thought 12 on a 6/6 Split, and quoted on this, but now if only 9 then its a large decrease.

Their quote was for 12x370kw, 5Kw inverter and 5Kw battery for €10,200 pre grant and based on their sizing net €7,800.

Now there will be zero reduction in cost because 3 less panels, and they are putting in 385Kw, but with 9 panels the grant will be about 2,200, so say they knock 600 for 3 less panels, and smaller grant then cost will be €9600 pre and €7400 post grant, but system is 3465Kw and inverter and battery, is this a good price, and how realistic is it that they way overestimate the no of panels 12 vs what's likely to be able to be put up.

There was a site visit and view of Google maps, but didn't go onto the roof until today, as for 8/9 panels I might have went with SAS provider, even without battery, as would have been half the price,

Any thoughts or what I should do, as they are back this week to start the install.

I don't know what the revised figure would be, just guessing but is 9 panel system worth it? For price

For the price the battery is too small next to pointless.

Personally, I'd add extra panels..depending on price of course. But my brother in law got the 29.99 offer without the eddi. I purchased a second eddi (1 for him) when getting my install done for 468 Inc VAT, a local electrician is fitting it.

1200 euro over 10 years v the upfront price is hard to justify in my opinion, but others may have a different opinion.

+1 for more panels over an Eddi. Houses are gonna use ever-more electricity (EVs, move from gas boilers, the more tech / devices we add...)

For me the Eddi only comes into its own when you have showers already running from the hot tank and the tank is well insulated. And for those houses where people like to enjoy a long soak under the shower. Otherwise, my view is stay with the electric shower and get the money back on FIT instead of sending to the hot tank via the Eddi.

I know many others here favour the Eddi for the reasons above. It's convenient to have hot water on-demand if you use a lot of it. But for our house, an electric shower is the better option. Different strokes, different...

Exactly

Wondering if anyone has a view on the below quote?

400 W Solar Panel - 10 Panels

Hybrid Inverter

My Eddi Hot water diverter

Van Der Valk Roof Mounting

Isolators, Cabling, Switchgear etc,

€ 9,000.00          Cost.

€ 2,400.00          SEAI Grant

€ 6,600.00          Final Cost

I don't think i want the Eddi so I'm assuming that will knock off about 500€ or so.

@cloughy, remembers the fight club rule of no installer names or major hints of who they are!! Well done on the install from the ********* company :)

All the worry of them not being able to fit the panels got sorted on the day, we had same drama with our installer. Now the fun / OCD starts checking the app every waking moment. Welcome to da club!

Hi. I have been reading through all the info, some excellent advice as usual, thanks for pulling it all together.

I am just starting to get a few quotes and got one today that I wouldnt mind hearing what folks think. It is the lowest quote so far, for similar kit from what I can see.

16 x 380 PEIMAR Panels (~6kw total)

Solis 4.8kw inverter

Eddi Diverter

It includes all the usual install, handling SEAI grant upfront, BER rating etc.

Cost after the grant is €10600, or €11400 to get hybrid inverter which I will probably end up getting.

As I said, It's the cheapest one I've gotten, even though its way over the rough guide calculator.

Is anyone getting quotes any closer to the rough guide calculation?

And by the by, all the vendors so far are quoting 4 to 6 month install lead times.

Thanks as always for any advice.

Anyone know with SaaS who owns the panels at the end of the 10 years? If its the homeowner what sort of life cycle do solar panels have, is there a point where they degrade and dont deliver electricity as efficiently as they did when brand new?

Also wondering if any posters here who have SaaS have inputed their production on that very useful spreadsheet, Id be keen to find out what they are generating with the equipment supplied by the Saas provider

Thanks con thats interesting. Do people tend to over spec their panels by 20% in anticipation of later degradation

At 10 years for 30 a month would work out at 3,600 and the grant is up to 2,400 depending on the size of the array. Which makes the net cost potentially as low as 1,200 and with them maintaining the system for 10 years should anything go wrong. It almost seems too good to be true, am I missing something here?

ok right the Saas website I was looking at didnt make it clear that the 30 a month is net of the grant which changes things a bit.

Still though Im going to get on to them regardless as Id like more detail. The main thing is what size array they could fit on my roof, its a typical 3 bed semi but it has a Velux window in the middle which might complicate things. At the moment Ive no ideas what size array would fit as it seems difficult to work out with all different sizes of panels and me not being able to measure the roof properly anyway. So I guess a survey is the way to go to find out.

I have been quoted the following:

8 x 415 Watt Panels -  Jinko

Optimizers

Inverter 3K (Huawei)

Eddi

Total 9k before grant.

No battery

Install+BER+etc.

Is this a good quote?
