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

I'm doing a DIY job at the moment.

• 6 panels amounting to 2.3Kwp
• 3x two panel microinverters (out of stock) and telemetry logger
• Isolator
• Assorted cabling (DC connectors etc)

Approx. €2400-2500 so it's pretty close to €1K per 1Kwp, but that's me doing the labor. (and doesn't include the mountings.....which are also out of stock). Good luck in getting close to that from an installer. Still, the revised formula of

€1.2k per 1kWp in panels + €1K per 2kWh in battery + €550 (diverter/Eddi) = Rough price to pay. 

is probably not a bad target to aim for on 5 Kwp systems and above. Smaller systems will be more difficult to meet that target.

Hi Folks,

We're just starting out on getting quotes and the first is coming in at about €12.5K before grant. From reading the last few pages of quotes this looks a bit high?

Install 14 No. 405W Jinko Solar Panels (5.67 kWp) - €8,169.00

Huaewi Sun2000 5KLT inverter - €3,569.00

 Eddi Diverter - €1,269.00

Supply and fit panels in landscape layout - €472.00

Building Energy Rating (BER assessment - required for SEAI grant) - €349

 Total (inc VAT) - €12,445.20

Hi. Just to give you an update on my hunt for quotes so far. I’ve got a few and there was a good bit of variation for more or less the same installl. The best I’ve gotten so far and probably the one I’m going to go for is as follows:

panels: 12 x 400W Longi

Hybrid 5.0kW Solis Inverter

5.3kW battery (Dyness)

Eddi Inverter

1x optimiser

fireman switch

1 backup socket to be installed downstairs

Gross Cost = €11,000

Net (after grant) = €8,600

Bin that and look at the few posts after yours there is a lot cheaper out there.

+1 in behind con747. Interesting side point, the Eddi is about €500 to buy.....

The UK's 1# Solar Power Diverter: eddi | myenergi

And they are charging €1,269? Sure, there's a bit of work for a spark to wire it, maybe 20-30 minutes (about the same difficulty as installing a 2 gang socket in a wall). So €750 to install it.....for 30 mins. There's your litmus test right there.

Absolutely not, bin it. Keep on looking you will find better value

Thanks Folks, appreciate the steer on quote 1 ( and thank you for the supporting PMs)

For those curious, the provider was not on the list of suppliers pinned in this forum.

Next few phone calls will be to that list though.

Ok im back with the most competitive quote ive got so far .

16 x suntech 405w panels = 6.48 kwp

Solis inverter.

eddi and harvi included.

5kw battery

12598 euro -2400 =10198

Same system but hauwei inverter and Hauwei 5kw battery =13650 -2400 =11250 euro.

Is hauwei inverter /battery combo worth the extra over the solis and 3rd party battery?

Hi all, back again, so currently looking at 10 panels, was going to get battery, just over 4 k extra, And next year replace oil condensing boiler with heat pump. Would I be better spending money on heat pump now and not get battery as supplier is suggesting battery will not be used as boiler will take most of electricity produced. New heat pump will cost approx 8k.

The other point with Huawei is that you have to stick with a Huawei battery. I've been told that having Huawei inverter and battery reduces potential of communication errors but also some reports solis inverter works better in overcast conditions but I've no clue either way...

So maybe I didn't explain very well, phone was running out of battery.

10x 400w cell mono panels, solis hybrid dual inverter. 3.6kw, Dyness 2.4 kw b4850 x2. €9490

Without battery, 8 panels, 2.5kw mini5g single tracker solis inverter. No immersion controller needed. €5262. Have panels already for hot water.

Both post grant. So the question is would I be better off using the price difference between the 2 quotes to off set the cost of heat pump. Or is this false economy, and get the battery and forget heat pump until next year. as I currently cant afford both. Thanks for all your help, this has been very informative.

Thanks Maulbrook, not sure if I have space for more panels, but thanks for advise its a question to ask.

Think I'll go with cheaper plan for now, and add more panels later, and rethink about heat pump.

Reading on here it appears the value is not there in the battery at the moment.

Fair point, nothing is 100%, you are quite right, just cost/return factor, with price of battery, and the loss of grant, its not working for me. Using battery of an evening for tv, fridge/freezer. As I can use the electricity during the day mostly as I do shift work.

With the figures you are saving, it is very worth while, well done.

@saccaromyces Do your homework on a heat pump. People who have them appear to be using collosal amounts of power. It looks like you really need an A rated house for a heat pump to make sense.

I can't help but feel that heat pumps mis-selling could be the next big scandal.

It's a difficult one isn't it.

We're in the same position. We decided to go with 12 panels (4.56kWp) and an Eddi. No battery as the math didn't work for us at our age. Plus CEG tariffs are beginning to filter through at 13.5 and 14c per unit.

We went for a MyEnergi Eddi as, like you, we have a relatively new condensing oil boiler. Eddi pushes any surplus solar energy to the immersion in the same tank the boiler heats, meaning the boiler works less and uses less oil. Assuming you don't have a combo boiler, this should work for you too.

We've only had panels for 9 days, and yes, its been reasonably good days for sun, but we've only topped up the hot water twice in the morning because we had a visitor that showered in the mornings. Otherwise we would not have used the boiler at all since fitting. In the winter, cold sunny days will still see surplus helping heat the water. Eddi uses power that otherwise would be exported as Eddi only uses power after the load of the house has been satisfied. Even 200 Watt excess can be utilised by the immersion.

Hopefully the price of oil will reduce, as will electricity, but it doesn't change the fact that your solar panels will continue to heat your water tank which, in winter will always reduce your oil usage by heating the tank.

My recommendation; solar panels plus Eddi.
