Thanks - not those thankfully

Quick question... The "rule of thumb" mentioned above, i.e. (€1k per 1Kwp) + (€1k per 2.5Kwhr battery), is that including or excluding VAT?

bullit_dodger · 23-11-2021 3:57pm

Including VAT - basically it's the price that that the average Joe Soap would be "out of pocket" doing an installation at home, grant money included.

Again, I'll stress it's just a good target to aim for. Many (most?) suppliers won't be able to match it. Some will beat it, but if they are within a few % points, that's ok - your not being ripped off. it's not a binary thing. The purpose of the formula is to give end users some appreciation of roughly what to pay. People come here (myself included) and while I'd be "tech savvy" it's hard to know what is a "good" price, until you spend time and effort understanding the domain. It's not my formula either, but one that I like.

If it stops some people from being gouged for €3,000-4,000, that's a "win" and the main thing it's trying to achieve - at least in my humble opinion. I think if I'd overpaid by €3-4K I'd be pretty cheesed off. If I overpaid by €500-600....not so much.

If we are starting a new 2022 thread, can I suggest this is the first post so it is visible to anyone looking for guidance on prices?

Installation due next Monday, panels, battery and Eddy. What are the things to look out for, make sure that they are done in certain manner etc?

Leave them alone and don't get in their way. Plenty of tea/coffee and the good biscuits.

Its that simple.

Can somebody PM their details?

Do they install further afield/nationwide?

Could you PM me too?

Nationwide is not a problem.

PM Sent

MAULBROOK · 23-11-2021 9:14pm

Question, why cant people just say where they are located and not just nation wide?

Some Nation wide companies might be a little more expensive than a local contractor.

Not necessarily @rx8

I spoke to the boss man last week re another issue (some electrical work) and he said that they may have to limit themselves to the north of the country, Dublin and above as they're so busy.

Savememoney mentioned in the thread a few times is now called Veep energy

Same thing happened to my preferred installation company. They are out the door with jobs.

I think its even more important now to check company references from previous customers.

I have just received a quote for almost the exact Solartricity kit linked below (7x360kW + 2.4kWhr Battery), priced by Solartricity at €4,463

(Price tweaked to include the 3.6kWhr battery).

Quote I received was for €7,835 / Grant would be €2,550 / Net cost after grant would be €5,285

Now, going by the rule of thumb shared elsewhere on this thread, I should expect to pay around €4,000 net

I've gotten worse quotes than this; in fact, this was the best of four quotes I've received.

But I kind of think the margin here is a little high, i.e. around 30% higher than expected.

Can anyone please DM contact details for any reliable installers in the Dublin area?

I think I need to get more quotes!

Anyone have any experience of this.. products/component/huawei-backup-box-1-phase/ .My understanding it's being sold as a switch over method during power outages ""supplies backup power to homes during a grid failure. This allows homeowners to seamlessly operate off-grid .Would be ideal for what I am looking for if true.

Most hybrid inverters have a backup power supply built in via either a standalone socket(s), a sub consumer board with a small number of circuits on it or a manual change over switch providing power to whole house (but obvious caviat here is what power your battery/solar can provide). I'm not sure what the huawei (and sonnen do it too) backup box does extra that is not achieved with the hybrid inverter and manual changeover switch.

Gumbyman2000 · 25-11-2021 3:06pm

Hey! Long time lurker on this thread, finally close to taking the plunge. I have a few quotes, the best one is a quote for 22 panels, 8kw (12 on East face, 10 on South), iBoost diverter, 8kw solis inverter, zappi. 8600 incl VAT, net of grants. I might need additional optimisers on the East face as there is a pesky dividing ridge in the centre of the roof, this is TBD.

Does that sound reasonable? I’m in the Limerick area.

Would also love to get a 2nd opinion on my overall plan for it. Main bit of uncertainty - I am not getting a battery but will get an EV so between that and the hot water diverter I plan to mop up most of what I produce. Was toying with getting a battery too, mainly for the Summer to contribute to some of the night usage but if I switch to a Night Saver meter this makes the payback questionable. The system quoted above leaves the option open to add a battery down the road if it looks like a better option.

Thanks all (and thanks for all the info everyone has added to this thread, so useful!).

That's a good quote that.

It's always a harder one to call when you have an EV in the mix (in a good way). If your EV is present for most of the day when the sun is shining and your producing, your right, the need for a battery is mostly diminished. Course with 8Kwp (which is a nice big system), you have to be actually driving a lot to be able to absorb that generation. What it is.... 5Km/1Kwhr or there abouts? So if you put 30kWhr into it on a day, that's 150Km you have to drive to lower it down for the next day.

Obviously I don't know your usage, but to give you a question to ask yourself......would it not be the case that if Monday is sun shining and all the generation goes into your car battery, would it not be full when Tuesday comes along? Where does your surplus go?

A hard one to call without knowing more details, but I'd probably drop back to 7Kwp and then get a 5Kwhr battery. However if you can afford both.....rock on! I know......I'd be going against the grain there with reducing panels, but having a mid sized battery gives you a lot of flexibility. I'd even prioritise it over a EDDI - as you can in effect do the function of a EDDI with a battery. Just manually turn on the immersion with the energy you stored in the battery - but naturally you can't power your tv/kettle from the energy which is in the hot water tank. So the battery gives you some options. 5Kwhr is good for most people, but if you have the consumption.... payback is slightly quicker on larger ones. Expect ~10 years. Less if you go DIY on the battery.

Good strategy that most people do with night rates, is charge the battery in the winter on night rate when you have abysmal PV generation, and then use that during the day to help pay for itself. Having a battery helps smooth over breaks in sunshine too during the day. e.g. sun has been shining all morning and at 11am, you turn on the washing machine for 2 hrs, and then 11:30 the clouds roll in!

AndyBoBandy · 25-11-2021 4:58pm

Are any providers still putting people on D/N rates?

If you have a smart meter installed, Theres no option to switch back to a Day/Night meter right?

slave1 · 25-11-2021 5:07pm

https://www.boards.ie/discussion/comment/118221890#Comment_118221890

Consensus here points to no going back after Smart Meter install unfortunately

Have copied this all to my MASSIVE 'solar' file ;-) Thanks a million - great points there, more food for thought but good to know I'm not doing anything nutso. Will look into the 5k battery. Thanks again!

rainydayhere · 25-11-2021 6:08pm

Can someone give me details of a good solar installer in the Limerick North Tipp area.

I got 2 quotes already

10 panels giving 3.95kWp with 2.4w battery & hot water inverter €11,252 less €2952 grant = €8,300

12 3.16 panels giving 4.38 kWp with 2.4w battery & hot water inverter €11,800 less €3000 grant = €8,800

After reading I should be paying €1k per KW + €1k for battery am I being over priced?

rx8 · 25-11-2021 6:53pm

Both of those quotes are about 2k too high IMHO

DrPhilG · 25-11-2021 10:30pm

https://www.boards.ie/discussion/comment/118222512#Comment_118222512

You're being generous. I'd say €3k over.
