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

A family member has been given a quote which I'd like to run past people who'd be more in the know than me - I live in NI, so I'm not familiar with the market there. It's €6700 for a 3kWp roof installation over 7 panels, with a hot water diverter but no battery. The quote says "this quotation excludes the SEAI grant" - please correct me if I'm wrong about this, but I'm fairly sure that means that the amount of the grant (€2100) should be subtracted from the subtotal, giving an overall cost of €4600.

The roof of the house isn't one uniform rectangular area - there are dormer sections in the south-east facing side. This would probably require panels to be placed in three or four locations altogether, quite possibly on either side of the main two halves of the roof. However, while this might involve a little more work/wiring than putting in one bigger uniform array, to me this quote still seems on the high side for a 3kWp install. Am I wrong?

So it cost you €5240?

Can anyone advise me about appropriate cost of getting a crossover switch installed and anything else needed so that the battery can run the house in the event of a power cut. The crossover switch itself is very cheap but i don't know what else is involved. Anyone who got it done, what kind of money did it cost on top of the solar installation? Thanks

Qoute for 16 jinko 430w panels ...6kw system, string inverter and eddi hot water diverter. 7k after grant. Thoughts? Tried that link and seemed to suggest it was fine

Inverter must be capable of off grid operation, without being tied to a mains input. On grid inverters, even hybrid with a battery, will stop when the mains is absent.

Sungrow have inverters that have a split output, ongrid and offgrid. You seperate your consumer circuits, and place up to 2kw, iirc, on the off grid output of the Sungrow. It will supply these circuits from the grid when power is on, then switch to off grid if power fails, panels and batteries permotting.

what are you hoping to achieve? Do you want 1-2 “backup” sockets to work in the event of an outage?

of do you want certain circuits to work? For example; lighting, heating,

or do you want everything in your house to work?

do you know which inverter and battery your getting?

Do you also want the panels to be able to provide power in the event of an outage?

It’s mainly a matter of running an additional cable between the inverter and the consumer unit. And depending on what your trying to achieve; a bit of reconfiguration of the breakers in your consumer unit. Electricians might make it sound complicated; but it’s very simple.

i wasn’t trying to discourage you; i was just trying to know what your looking do implement so i can better advise you.

which inverter? Its implemented differently for different inverters.

It would be an identical setup to mine; I have the same equipment. I’d you want I can give you the details. I have some diagrams I drew at the time also.

Hi All

I am getting 14 x Denim Glass 430Wp panels (6.02Kw System).

I've been offered 2 different kinds of set ups and I am not sure which one is better or worse.

Option 1:

1 x Solar Edge Inverter (12 yr Warranty)

1 x SolarEdge Import / export meter

1 x Eddie / Solar Edge Hot water diverter.

Option 2:

1 x Huawei Hybrid Inverter (with 10 years warranty)

1 x Huawei Import / Export Power Sensor

1 x Eddi Hot Water Diverter (with 3 years Labour and Parts Warranty) - Dont know the brand but think its the MyEnergi one.

Obviously the 2 year warranty helps but is there much of a difference? I will probably add a battery in the future once the prices come down.

Thanks in advance for any advice.

*Cost of system is €9k before grant applied.€6600

Not sure about he Solar edge, but my understanding is that with the huawei inverter you are limited to huawei battery ( and possibly one other type) if you chose to add later. Not compatible with other batteries.

I found this out after paying deposit for huawei system. My own fault for poor research and haste. Anyway I didn’t get a battery and possibly never will if FIT stays reasonable.

Hi all, anyone know if the below price is reasonable? Also another input, advice or questions i should ask would be greatly appreciated.

8 x 400w panels
