Think that was referring to my quote

11k for 4kwp (actually 4.5kwp) with 5kwh hybrid battery, hot water diverter and non essential load config, including ber.

12k for same system but 6kwp solar.


Prices are including vat but excluding grant, so take away 3,800 from either price to get the end cost to you.

Hi wexfordman2, Could you pm me your installer too if not too much trouble? Thanks.

Sooo finally got the dongle so can get some online graphs.
Didn't go the grant route as I wouldn't have been able to put up the panels I wanted on the roof based on their limitations.

3.3 kW system
Solis Hybrid Inverter 3.6kW
11 JA Solar 300W Panels

Will install the battery when I get the money together for it. Will use the grant for that as I installed with that in mind (cable back to fuseboard for back up and hybrid inverter)

Ignore the mess, I've tidied up since I swear!

So as per usual the sun hasn't shone since the day I installed.

Nice ine Gary, hope it goes well for you. My generation today was 3.5kwh with a 6kwp system .


What logger are you using ? I've noticed a lot of people are able to post up graphs and plots, but I can't figure out how to do itm. I am using the solarman app.

Got my brand new Solis 3.6kW inverter myself in the post yesterday. Ready to be installed by an electrician at the weekend

Still contemplating an AC side battery + storage inverter to avail of the €1k subsidy, but will have to be up and running in my new setup first before I make a further assessment.

Anyone watch that programme tonight on rte about the deep retrofit grant?

Would it really take about 30,000 euro (30,000 euro from home owner and a 30,000 grant) to go from a E rating to A rating?

Ours is rated at D1 so would probably be in that price range!

What did it cost you in the end?

You said getting all the panels would have effected you getting the grant. Can you clarify?

I'm relooking at mine. Forking out 8k is starting to get me to question the specs I was getting.
What's the minimum of need? Need to be able to have essential load for a well.

Can someone give me ballpark cost of a 2kw battery. Quotes I'm getting aren't granular enough for me.

unkel

2.4kWh battery is EUR950 + VAT. Install less than an hour. Subsidy is EUR1000.

Beware you either need a hybrid inverter to hook the battery up on the DC side, or a dedicated battery inverter if you hook it up on the AC side

Yes. Complete gutting of existing house.
Air tightness.
Insulation
New heat and hot water system.
Plumbing and electrics afterwards.
Windows, doors

our energy works is closer to 90k total...

Includes new windows though.

I wanted to go with a builder service provider as there is other work I want done, however there are certain items where he's taking the pi$$ (6k for PV for example)

Also the DCV they are planning is not Aereco but "Innovent" or something - told me on the phone.


Don't think the SEAI are capable of looking out for value either. He's said they will check for value when assessing the application - though I'm starting to think that means they will cap the grant and expect me to pick up the slack. He can go and jump if that's the case - I'll withdraw from scheme and fill up the old oil tank...

About 4200 in the end.

There's a limitation on the panels being 0.5m in from each roof side which as you can see from the photos isn't the case for me. I've heard that doesn't really matter but most costs were coming in around 8 with grant anyway so it saved me forking out money and waiting for the grant to come back anyways.

So,the battery is €1,230,installation €200 i guess. Back at soem point, €1,000.

How much is a hybrid inverter on its own plus the installation (removal and fitting),please .
Can you "dump" the older inverter back on the market ?

unkel

5kW solis hybrid inverter is about 1200+VAT

I guess a callout charge incl one hours labour for about 80+VAT to replace your current inverter

Of course you can sell on your old inverter. I have 2 for sale myself on adverts.ie

If I'm going battery, I'll go the AC side myself. Maybe later this year.

No mention of Eddi in their FB post. But tbh, I’d rather a battery than eddi. Eddi saves pennies, the battery has the potential to save a decent chunk.

For example, today my system generated 6.44kwh.
2.96kwh went to the immersion by way of Eddi divertor.
The balance powered the base load but I guarantee you most of the balance went back to the grid for free.

If I had a battery, say a 5kwh one, I could have filled that and my
House would have been powered until tomorrow morning off grid. I could have heated the water for a small amount using the immersion or gas boiler.

Yep,

Mine is with battery (6kwh) plus eddi. The eddi isn't installed yet , but today's generation was 12kwh, the battery was charged last night at night rate and then kept topped up during the day as excess pv power was generated.

With 6kwh battery, it only.dischsrges to 10%, so a available.battery power is 5.4Kwh.

With that 5.4kwh, I generally find it depleted by about 8pm so far, mainly.due to early sunset times, and electric cooker comming on for supper which is high load.

All you need to do is turn off the lights after dinner and you're virtually self sustaining:)

Why isn't your Eddi installed?

The inverter they installed was a 3.6kw one as a temp measure until the required 6kw one came in, so they plan to finish all in one go.

They knew they were messing me about a bit with delayed install (not entirely their fault, seai had delayed some bit I believe from paperwork and sign off list etc, and they were awaiting a firmware.uograde.on prime hybrid interver which had a bug that was affecting battery system), but def they we're over stretched a bit as well. Had the owner call round to me to apologise (not a short trip for him,.so genuine enough).

He offered me as a way of apology an option of.going for a Soltaro system which had a bigger battery system, but they would install the smaller inverter short term).

Paperwork sign off i.e. crossing t's and dotting i's was the longest most painful part of the process for me.

E.g. Your MPRN will have one address and your Eircode might be slightly different. Electrician might use Eircode address, The application will be in under your MPRN number.

If everything doesn't match your mprn number exactly then it will delay your application. SEAI will not be proactive and tell you this . They wait for you to cop on there is an issue and for you to contact them. Then due to GDPR they won't tell you because the contractor filled out the application and not you.

I put it down to SEAI teething issues but it was very painful and delayed payment.

Tio Eddi or not to Eddi?

So I've just ordered the Zappi and Harvi.

I'm wondering for 400 or so should I go ahead and order the Eddi?

I'm guessing my return on that is LOOOONNNNGGGGG but it would mean an extra source of hot water without thinking about it. i.e. I have hot water scheduled to come on for an hour, but if during the day there are people at home (using ridiculous amounts of hot water) then by the time the kids have the baths and herself has a shower that night it's starting to get a bit chilly.

Yesterday, my system generated 12kwh and sent 7kwh of it back to the grid. It.never generated at any one time anything above 4kw, so fir a 4kw system, I lost 7kwh to the grid (my.eddi isn't installed yet).

So that's a figure for early january, I am optimistic that I will get decent levels of hot water in the summer to negate the need for using the oil.

Having a zappi changes things for you though, assuming your car will be olugged in during the day.

Only plugged in at weekends so ideally would take excess then (not sure how much if we're home I guess?).

During the week, no one is home, resting power is 300w, I have a good chunk of excess too out of the 4kw generated yesterday maybe 2kw dumped, 0.25 litres of oil, 20 cent basically.

Alternatively I could look at it:

=> €400 (cost of eddi) = 500 litres of oil = 4000kwh

unkel

You know I have argued against an immersion diverter in the past, GaryCocs. But if you have a large (>=4kwp) PV system (and no EV plugged in during the day much and none or a very small battery), they start to make sense.

Yup. I remember you saying it and 4000kwh is a lot to make up all right. Especially if I have solar thermal (a right dose) already.

I think it's the combination of a cold shower and excess yesterday

Ours is rated at D1 so would probably be in that price range!

They said the average heating bill is 2,500!!!! Our standard 3 bed semi built in 83 is 600 a year with gas!!

You will I went from April to October in 2018 without turning my gas boiler on at all. I generated all the hot water needs from the panels. I posted about it in real time on these forums too.

That of course depends on how many units the Eddi sends to the immersion in its life.

With a small system, like 2kwp, your point is probably true. With a large system (like >=4kwp), it will more than likely pay for itself well before it is dead

You wouldn't install a hot water diverter if you use very little hot water. Also with modern cylinders the heat loss is minimal. My 360l cylinder loses just 1 degree C per 24h

No. It doesn’t. Because ither firms would be classed as dispatchable. In July if I don’t need hot water I won’t heat it with gas or mains elec with a divertir it’ll heat the eater even if you are away for two weeks

I talked to company and they mentioned infrared heater, they can be disguised in the house as picture, excess electricity is used by the heaters....in that case it wouldn’t heat the water

Trying to use excess electricity to heat water for heating would have a similar affect as peeing into a lake to try and warm it up :-)

Better off looking at infrared or heat pump

You are looking for a system to heat your house during times when the max heat requirement (winter and night time) conincide with the lowest possible availability of your power source.

The infrared heater works better, according to this company, it doesn't heat the air, it heats object....something like that

The amount of water in my heating system it would take a huge amount of electricity to heat it to any level to heat the house

My latest pricing

10 Panels (3.25kw) of PV and 5.6kwh of Prime Hybrid Battery Storage = €9,500 + VAT (13.5%) = €10,783
This would allow you to reclaim €3,240 from SEAI for the install = €7,543

13 Panels (4.25kw) of PV and 5.6kwh of Prime Hybrid Battery Storage = €10,250 + VAT = €11,634
Reclaim €3,800 from SEAI = €7,834

IR heats you, as an object. It’s not any more or less effective at heating than rads, it’s just that you can walk into a cold room, switch it on and feel the heat yourself. Switch it off and the room is still cold. Any “savings” in efficiency really only come from using it more directly and thus running it for less time.

In solar terms, IR can heat other objects with thermal mass (e.g. a granite worktop) which will indirectly release the heat into the space in due course, but that’s no better than having a rad doing the same. It’s a poor match for solar PV really, from what I can tell, unless coupled with a battery.

Your 18 panels system, does it come with an eddi ?

_dof_

IMO, using the excess to heat water is a better choice, since it will be used year round. Any IR heating of the living space won't be needed in the summer, so all the excess would be sent to the grid in that case.

Hi every one

So if someone goes diy route including getting separate electrician to hook the system to board . What is the cost difference or saving compared to the professional installer with grant.
