Thoughts on this quote?

12 x 335w Canadian Solar panels, Hybrid solis inverter, 2.4kWh battery storage saver system, eddi diverter 9700 - 3000 grant.

Not great. I paid similar for about 50% more panels.

Yeah, your quote was the benchmark I've been using when shopping around, but apparently the installer you used can no longer get anywhere near that figure either...

Had a few ridiculous quotes, which were binned straight away. Thoughts on these ones? Still waiting on a couple more.

6.1kW (18 x 340W JA)
Solis Hybrid 6kW
Eddi diverter
2x2.4 (4.8)kWh Pylontech battery

€10500 pre grant, net cost €7500

6.24 (16 x 390W)
Sofar Inverter 6kW
5.12kWh Sofar battery
Eddi

€11,250 Net cost €8,250

Second one is more local, which is a consideration for maintenance/any problems.

Still a grand to come off those quotes to get down to the best prices we've seen

I wonder are we reaching a point where the early most competitive quotes are no longer being matched or available for New Business. Labour, materials and demand may mean that it is of course essential to shop around and check here regularly to get a 'current' view of the market.

Boscoirl · 20-05-2021 06:15PM

I got the details of my installer from Slave1

He is nearly cursing him now at this stage. He is sending so much business his way from this thread lol

remoteboy · 20-05-2021 06:33PM

I have a quote of 5200 after grant deducted for

9x380w panels
1x 3.6kW 4g inverter
Protect switch
Isolator & cable
Installation

Or 7100 after grant deducted for the above but with a 5.2kWh battery and the inverter is hybrid.

And for an additional 1250 they’ll install a Zappi EV charger.

I’ve been told 9 panels is the most that’ll fit on the roof - it’s a semi-detached.

Would welcome opinions. Thanks.

Isn't the grant still available for the charger installation?

Sorry yes. 1250 less the 600. So 650 net cost. Should have been clearer there.

Clare in Exile · 21-05-2021 10:19AM

€5,150 after grant. 11 350 kWp panels, inverter, diverter and installation...

Both quotes are way too expensive I would say. Slate roof will add to the cost but the second quote is still a minimum of €1500 more than what you should be looking at.

I think anyone looking to install <4 kWp of panel should be encouraged to wait until after FIT decision is announced.

championc · 22-05-2021 07:08AM

Not really. I wouldn't be using FIT as a basis to proceed or to justify the cost of a system. Ideally, you want as high self use as possible,.

Wouldn't that mean a split east west like a gull wing design would be better than all flat panels so as to flatten and stretch the curve throughout the day?

Hi folks

Thanks for all the useful info in this thread. I have been in touch with quite a number of companies about the possibility of installing solar PV panels on my home.

It is a semi-detached house with a hip (tiled) roof, and there is also a single storey extension to the rear of the house. The main rear roof is south facing and will probably only have space for 6 panels given that a couple of velux windows will soon be installed for an attic conversion. There is a small east facing hip roof which would probably only fit 2 panels. The single storey extension has an east and west facing roof which would probably only fit 2 panels on each side, but for now I think I would prefer to just put panels on the two upper roofs.

5 people live in the house consisting of 2 adults, and 3 kids ranging in age between 3 and 11, and with plenty of growing left in the kids, a power diverter to the hot water cylinder is a must!. Pre COVID annual electricity consumption was 5,800kWh, where there is normally no one at home between 8am and 4pm Monday to Friday.

I don’t currently have an EV, but this will no doubt change in a few years. I am not convinced that a battery makes sense in an 8-panel system considering the load and usage pattern of our home, and the majority of salesmen agreed with me, which would lead me to be believe I might be on the right track. A few of them did say that batteries would only make sense now if I had space for lots of panels, and will likely make more sense in the future when battery costs come down.

Anyway, here are the three best quotes I got (all excluding batteries), where quote 1 came from a company based on Tipperary, quote 2 came from the myXXXXX.ie online company and quote 3 came from a company based in Dublin 11. All quotes exclude batteries and include wiring, switches, commissioning etc

Quote 1
Installed Capacity: 3.04kWp
No. of Panels: 8 consisting of 6 south facing roof and 2 east facing
Panels: 380W Qcell ML G9 Gapless Module Solar Panels
Inverter: Solax X1 Boost 3kw inverter 2 x MPPT
Diverter: Solar iBoost
BER: not included and would cost an extra €250
Cost after grant: €3,927 (incl. VAT)

Quote 2
Installed Capacity: 2.56kWp
No. of Panels: 7 consisting of 4 south facing roof and 3 east facing
Panels: 366W Jinko, Phono, Trina, or JA. Tier 1 panels
Inverter: Enphase
Diverter: Eddi myenergi
BER: included
Cost after grant: €4,198 (incl. VAT)

Quote 3
Installed Capacity: 2.84kWp
No. of Panels: 8 consisting of 6 south facing roof and 2 east facing
Panels: 355W Longi Tier 1
Inverter: Solis
Diverter: Eddi myenergi
BER: included
Cost after grant: €4,450 (incl. VAT)

Interested to hear people’s thoughts on the quotes and if they have any views on the companies, which I haven’t named, but people can probably guess!

Wonder are we still on track for getting FIT announced by July this year?!:rolleyes:

championc · 22-05-2021 08:32PM

@PGL You won't have massive excess based on your consumption levels and with only 7 or 8 panels. A combi boiler would nearly be a better option - to heat as you use. You'll never get much into even a Hybrid let alone a proper EV with only 7 or 8 panels.

Why so few ?

How does PV interface with the grid? I assumed a cable to the Distribution Board, but was told than just interface with a power circuit. Am confused. Anyone know is there a clear interface arrangemant

Yeah it's grid tied, it just connects into your consumer unit. Usually through a rcbo.

Was gonna say same, you need more panels to make diverting sense @PGL what’s wrong with front facing roof, during the good months of the year you will gain plenty of power from even a N facing roof, particularly in the mornings.
I’m not sure about a string with just two panels, they need to generate a minimum charge before they “turn on” the inverter....

First quote the best in any case.

I would be trying to maximize the amount of panels on the South and East. If 6 on on the South and 3 on the East is all you can get then so be it. But if you can get more all the better.

Remember panels are not that expensive. One extra panel should not change the the price.

championc · 23-05-2021 10:05AM

Mind you, too, @PCL the solar as a service would only cost you 2400 and then maybe another 500 or so for the Eddi which you could fit yourself.

You'd be better too going all in on the south and forget the east if possible. You'll have more hours of sun on South panels than on East ones.

Usually does mean a new cable back to the consumer unit.

Although with small inverters, it could be possible to tie into a socket circuit (load wise) have no idea where that stands in the regs.

Would be very surprised if you can tie into existing circuit. You should surely have an entirely separate MCB for the solar as it’s a piece of equipment? But would be good if we have a qualified sparks to answer for certain.
