how is a slate roof attached just out on interest. Hoping to know what to look for in terms of resealing the roof

I'd agree. I know someone in solar game a long time and well used to roofs. They fell off and took up residence in the hospital with a broken pelvis and was lucky to only be that. If a old metal gutter cracks and hits you, it's gonna be bad. I saw a very close call on that myself. Plus panels are 20+kg. And wind...

Still quote hunting and have just gotten this one:

6.0kWp

16 x Bisol Premium 375W Monocrystalline modules (All black modules)*

Bisol Mounting system

1 x Projoy Fire Safety Switch

AC Switchgear

Sofar 6kWp Inverter

Costing

€9,250 (inclusive of VAT)

-€2,400 (SEAI Grant)

€6,850 Final cost after grant incentive

Seems to match up well with the target formula. Few questions:

1. Any opinions on Bisol + Sofar in terms of quality?
2. Eddie separate to above @€650 which we'd be including so €7,750 total cost. How does this sound?
3. BER separate again I guess - not really a question, just thinking out loud.

Hard part is done, well done. If you've already got a few quotes and trust this installer, book it today so you get the next slot and get the slot agreed!! That's a really good price with market as it is. Get them to price guarantee that kit - get that in writing. You'll be paying a large deposit now, so don't want to find out in months time closer to install that prices have gone up.

Other odds + sods:

-Eddi price is grand, but it's hard to get your money back on it with decent FIT. But for comfort if ye use a lot of hot water from the hot tank, it's worth it. Very much a personal call.

-Kit is kit, so don't worry about 1 brand over another.

-People have gotten BER for as low as €200 - separate thread on it somewhere. Not uncommon to pay for your own BER.

Hi all, I have messaged 2 installers 5 days ago from list of installers thread that was pm'd to me, no response, emailed 3 other suppliers also on the installers list here - only 1 response saying they have too much work and only doing corporate work now.

Any advice by pm etc. on where I might get a Dublin installer welcomed!

edited - was pm'd list of installers

Hi all, hoping to get your thoughts on this. Due to limited roof space (Velux windows) probably looking at 8 panel/3.2kw system max. One supplier has said not sure it would be worth the investment, and that this size system is less than worthwhile.

Our current usage is roughly 4530 kWh per year. Orientation: S/SE 150 Deg. Roof Slope (degrees): 35

Would people agree with his assessment?

Thanks,

Mike

Is a 3.2kw S/SE system worth your while? Yes.

Then Q is if it's worth the installer's while profit wise. Different Qs as I expect you know. Have a look at solar as a service. Cost for small installs is at least north of 1.5k per 1kW of panels.

And see can you fit more panels. Flat roof is perfect or shed roof. If you can do that, then you can look at other installers and price per 1kW of panels will drop. Labour is a huge chunk of it. Panels themselves are under 200 quid. Don't give up based on 1 view

| Is a 3.2kw S/SE system worth your while? Yes. Thanks, as wasn't 100% sure myself.

Ya getting the feeling installers may deem it not worth their while in general, as not getting a whole lot of replies back.

Thanks for that, I hadn't really considered how to work that out. Sticking 3.2kw into that url gives a Yearly PV energy production [kWh]:3038.4. Then, did I understand you correctly regards the calculations as shown here (did this very quickly so it's possible there's a mistake somewhere!)

Kinda hard to follow someone else's formulas.

Let's pretend you use 4000 a year.

Solar (let's pretend) gives 3000. And of that you can only consume 40% (1200 units). And get paid ~15c FIT on the other 60% sent back to the grid (1800 units).

So you need to buy 2800 (solar is giving you 1200 units that you consume so not part of the calc as such). But FIT is paying you for 1800 units credit at 15c.

Get me?

This is without any divertor like a battery or hot water tank one. And % you consume is higher if an EV is in the drive during the day. But good place to start.

The rule of thumb of €1.2k per 1Kwp + €1k per 2.5Kwhr battery, including VAT, after grant deducted.....in gone. Forever, consigned to distant memory. Nobody....unless you are dealing with a shakey installer is getting those prices anymore. None here.....none on Facebook group.

At a very minimum the formula should be changed to €1.5k per 2.5Kwhr battery. Nobody is getting a 5Kwhr battery from an installer for less that €3k now.

Yeah con747 is spot on. The guideline was (even a year ago) always tailored to bigger systems, with a bit of leeway. Last year it was €1k/1Kwp so moving it to €1.2K/Kwp is bumping it 20% over last year, and indeed as "Bawnmore" posted in #3462 they smashed that guideline!

Again, it's not "golden rule" where if you don't meet it you are over paying. If you are there or there abouts with ~10% or so, you know your getting a decent enough deal. That's what the guideline is about. That and keeping the gougers at bay.

That said, I love the way people categorically label it as "wrong" and yet 10-20 posts back in the same thread someone gets it. LOL

I was wondering if anyone has had any issue getting the installer to complete the installation documentation and the Declaration of Works form for the SEAI after the work has been done? My system was installed by a well recommended installer on here back in June, but never got any paperwork other than an invoice, after the work was done. SEAI lads are now looking for them to upload the paper work and the company are non-responsive on phone or email.

Can you tell me any installer/supplier that's offering a 5kwhr battery for €2k after VAT?
