I would also like to at least break even over the 10ish year

That's not going to happen. Even if you got a much better quote than you did.

Your EW system is going to generate about 2.4MWh per year. If you use all of this yourself at the full day rate (and nothing goes to diversion), this is worth 2400 * 18c per year, or €432

In reality your savings will be a lot smaller. If you got your system for €6k, payback would be about 20 years. And don't get an immersion diverter, it will never pay for itself if you are paying for an SEAI installer to install it and your system is just 3kwp.

The good news is that it is quite possible your battery will last a lot longer than 10 years

All depends on fit. Quote is dear. But once Leo gets some time to think . Fit will be accelerated.

What ? My calculator says 14 years , where are you getting 20 year payback from unkel ?

yea he appeared to me that he knows good bit about PV systems! also installers work very clean, no mess left behind. whole installation done within 1 working day! i would highly recommend him

Could you PM me details please, thanks!

Neil. J. F · 26-05-2019 06:33PM

Thanks for the replies everyone!
I like the idea of solar energy, we'd like to do our bit to reduce fossil fuel dependance but I've got to say, all the different quotes with different hardware, different guarantees, battery or no battery, diverter or no diverter, exaggerated claims of money that can be saved, plus the worry about how good any of these suppliers are at actually installing this gear without destroying my roof or frying the electrics, is making my head feel like it has absorbed too much solar energy!
Would I be correct in assuming that both Stefs_42 & unkel are happy with their systems & installers?
If so I'd be most grateful if you could PM me details of the systems you have and the installers you used, because recommendations in this area are hard to come by. Needless to say, other recommendations (via PM) from anybody who has had solar pv installed lately, would be most welcome.
Many thanks!

He was quoted €8,500, but let's say he got it for €6,000

Max savings in theory is €432 per year. He'd do extremely well to have real life savings of €300 per year

€6,000 / €300 = 20 years

Note this doesn't allow for any maintenance, all parts are presumed to last 20 years, which is a big stretch for the battery and inverter. Also it doesn't take into account finance cost or the opportunity cost of money

Very much a best case scenario in other words

Indeed as people suggested, arrival of a FIT might change above figure and also increased eletricity prices

I'm a big fan of renewables, but I like people to have a realistic view of the cost involved. A lot of people are fed mickey mouse figures from their installer or from some online calculators that are dodgy

Agent_47 · 27-05-2019 04:27PM

I have one contractor name so far and the one to avoid based on high cost

Cheers all, sorted. Thanks to all.

Sorry, Agent, my PM's tend to be quite long, so was wating till i got in front of a laptop :-)

Just sent.

It’s gone quiet in here!

How is the sunny weather treating you all?

unkel · 28-05-2019 08:35PM

I saw over 3.7kW today. Not bad when my inverter is only 3.6kW (and my panels are 3.8kwp and in two different direction strings)

Stefs_42 · 28-05-2019 08:38PM

my max today 3.34kw

happy out since my max system is only 3.6kw. shame tho as Mr Grid took most of it

AidenL · 28-05-2019 08:40PM

I saw 141kw being generated today on the array in our head office. :cool:

uck51js9zml2yt · 28-05-2019 09:38PM

Im really starting to rethink the idea.
I got an owl monitor and have been using on average 15 KW per day for the last week or so.

Am I right in thinking I'm unlikely to match that with 16 PV panels?

It "may" be worth getting the panels and diverter but the thoughts of a battery are quickly being reigned to the compost bin.
What's people's thoughts?

16 panels without a battery will give you 1400 euro of a grant.

15 panels with a battery will give you 3,800 of a grant.

You can add all the panels you like, it wont matter if you cant use what you generate.

Your total usage per day is irrelevant also. You need to know what time of the day you are using it and if that coincides with the sun shining!

If you add a battery, that gives you a longer time window per day to utilise what the panels generate but the cost goes up significantly by adding a battery so you have to keep that in mind if payback is important. Personally, batteries are not yet worth it.

Price the system with or without a battery, and see If the reduced seai grant makes it.viable.or not

A south facing 16 panel system will generate about 4.8MWh per year. That's an average of 13kWh per day

Of course on a good day you will make 40kWh and on a very bad day you will make nothing

A pylontech lithium battery costs approx. 1k. SEAI grant for battery is 1k.

Why not go for the battery in this case?

Plus you need a hybrid inverter instead of a conventional one. That's another 1k extra. And you need to pay the SEAI installer for the install. Probably another several hundred quid.

The argument for getting the battery is that you get the additional €1,400 subsidy for going from 2kwp to 4kwp only if you go for battery install. So 4kwp without battery gets €1,400 subsidy and 4kwp with battery gets €3,800 subsidy, so it starts making sense then

Still, your pay back time is far shorter if you do a non-battery, non grant install

That said, If I had no PV, I would have probably gone for a 4kwp battery install using the grant if I had the space on my roof

Had a visit from one of the recommended pv installers from this thread. They are doing up quote and will keep you all updated.
We have a 60 year old tiled roof and I made a point of asking how this company fixes rails to the roof, the answer I got worries me, as he told me they drill through the tiles to a rafter and use bolts to fix the rail. Surely this is not best practice? The SEAI website states that this should not be done. Am I worrying to much?

Normal practice is to lift the tile and put roof hook bracket on rafter as far as I know. Possibly drill into rafter. Wouldn't be too pleased drilling into tile.

Walk away. imo, thats the cowboy way of doing it.

It might be fine the day they leave but after 10 years of storms and rain i would not trust that it would still be fully sealed.

Thanks guys! And with a potential 6 panels either side of the roof, that's a lot of holes in my roof!
