Domestic Solar PV Quotes 2020

To battery or not to battery? As a total noob and technically challenged!, I'm mulling over the various options and I'm siding on not going for battery at all, so.. consume > divert to HW > divert to BEV (when I get one!) > grid feed-in (whenever ESBN gets around to finishing the new meter rollout!).. straightforward to configue this now to fit future needs?

going to drive whoever I consult with bonkers with my ignorance!

We are a two BEV household, PV goes to house first, then hot water or BEV, night rate is so low in this country and batteries are so expensive I cannot see any payback if going BEV route (don't forget you also need to get a hybrid inverter with a battery setup which is double the cost of an straight single phase inverter)...Grid feed in will commence July 1st this year, that is confirmed

Is it just me or does that Pylontech battery price look way too high?

No thats what they are selling them for

Sorry but no, €1,768 ex VAT is loopy, Midsummer have them at €884 ex VAT, £602 ex VAT in the UK if that’s a possible source for anyone

Agreed, if I remember correctly my installer was just over €1k for the PylonTech I got, then minus grant.

Keep looking then, my BER was €250, also some folk are not getting grants so not relevant always.

My BER was €180. There are some perks in living in the wild North West.

Crowd in Tallaght do them for max of €140 if you do a google!

Does that cover both the before and after BER assessments?
I assume there are two.

Incorrect, Only an after required for Solar PV Grant.

I assumed the 300 quid quoted earlier for it was for two - that is pricy for 1!

In some cases two are needed as the 1st one will let the client know whether after installation the house will reach the standard needed to get the Grant.

A useful check if you live in the likes of an estate is to check houses for sale/sold and their BER, this will give you an indication if other house of similar build

About that Battery

I got 2.4kw/h pylontech with Solis Inverter and the Wifi stick. 2k extra for the install.

But I just love that it records every electron. It tells me where and when I use my own, how much I am wasting, who are the real suckers (dam those extra long showers) all day and night like a smart meter I guess.

And I do think (smart) loadshifting is number 2 to go greener after trying to reduce consumption.

Would really love V2H/G with some decent incentives

884 x 2 = 1768.

Thought an accountant would spot that

I guess that was my post and in copying over details I messed up number of batteries. I remember when I posted was slightly surprised as was sure I had originally picked 2 batteries to match my 5.7 kWh batteries !!

’ve been following this thread for awhile and am looking for some feedback on the following system.

Amerisolar 320W x 12
Solis 3.6k Hybrid inverter
Pylon Tech US2000 2.4kW Battery
My Energi Eddi Hot water Diverter

€6205 after grant is current best quote.

50:50 split in panels on 2 strings between south and east facing roof space.
Family of 5 with main shower fed from cylinder hence the Eddi.
Not decided on the battery. The intention would be to get an EV in the next 2 years and it would seem logical to avail of the grant to get installed now.

I have a similar system, with 14 panels,eddi,2.4kw battery, WiFi monitoring and 5kw inverter. It cost me €6400 nett, 18 months ago.
Costs should have come down since then, and if I was doing it again I wouldn't go for the eddi, as I don't think it's worth it tbh. As others have said on here previously, fit as many panels as possible and go for the 5kw inverter.
Check your pm's.

Get a 5kw inverter and get as many panels as you can fit. Get as much on the south as you can. no harm with a battery imo it will maximize the grant 3k

Still very high, I'll PM you a supplier to try.

I like my eddi but financially I'm not sure it will ever pay once the FIT comes in.
The battery is a no brainer for me, 5c (when FIT arrives) out vs 14c in. So 9c saved per kw - over 10 years that's >€1000. With carbon tax going to 100e a ton energy costs are just going to keep rising so I think that €1000 will become a higher number in 10 years time.

I would say it’s a little high. But not much.
Get a 5kw hybrid for sure. They are only a tiny bit extra. 100 euro or something. Very little anyways.
Get more panels thrown in if you can fit them.
I got a 20 panel, 6.8kw system with 2.4kwh pylontech and solar iBoost for €6,800 after grant.
So yours seems a little high alright.

Not a quote as such but I was punching some numbers in Excel.
Going with a ground mount 5kWp system, no battery or eddi as we will probably have a phev at home for most of the day (have a Leaf but that isn't home during the day).

From the pvgis web site I downloaded the hourly data of actual sunshine and worked out the hourly data for an average year.
I went out and used a theodolite app on the phone to get an accuratish horizon including houses/ trees
I've also got data of electricity usage also hourly, a bit patchy but 2017 was near complete.
End result: when facing SW at 33deg
Max gen: 3945 kWhr/yr
Act pv that would've been used: €404 (@8c / 16c night/day rate)
Not used: €219

Cost of system (solartricity) €3300 (14 panel, no battery)
Say €1200 for ground mount/sparks etc

So a payback of 7-10 years depending on how much of that extra I can use. This is compared to 25yrs payback for a quote from an "active" company

How did you calculate the €404 per year savings?

Thats a pretty short payback, i know its not all about payback and more about the environment . if you can self install that system you are on to a winner. Its a good feeling when you finally know its paid back and you are in the green. It took me about 11 years to clear all my original outlay. Self install also. I originally had to pay for planning and there was no grant. Getting paid excees from the grid helped alot.

A direct hour by hour comparison between my actual usage in 2017 and the data from pvgis. 8c/kwhr < 8am and 16c other times as I have dual rate meter.

So that doesn't account for changes in habit to maximise utility, but also misses any short team peaks

slave1 · 18-03-2021 10:15PM

Switch provider, you’re paying 2c more than Energia night/day rates

Not quite sure what you mean. But your maximum theoretical saving is 3945 units produced * 14c (Energia) = about €550 if you use every single unit, send nothing to car, nothing to immersion, nothing to battery, nothing back to the grid and don't use any of those units for use that you could have done during the night (like running appliances like dish washer and washing machine / dryer)

A real saving of over €400 sounds very optimistic to me

Using 14 instead of 16c would drop that by 12.5% to €350
But what I compared it to was actual usage recorded, we do run some things at night but day time use is high too, more than 1 load a day, electric oven, heat pump (mostly night, but would certainly use all the early morning solar), wife works from home and normally has an extra heater in the office.
Yes, we could make free savings by changing somethings but the point is we didn't :-)

Now I might go back and look through the data, maybe try a to make another file out of the patchy data from other years.

But add in the fact that there might be 2 phev/evs and realistically only one will be plugged in at night i think our utilisation will be quite high. Even a 10-12 year payback would be good.

And part of getting solar panels is the green feel:-)

unkel · 19-03-2021 11:01AM

Oh aye and with a bit of micro management you can sure get your solar utilisation up really high. But we have to be realistic about the real savings. Your heat pump using all the early morning solar and your electric cars on solar are saving 8c at best, not 14c

Or even more dramatically - Energia have just launched an EV special plan that only charges 4.79c (incl. VAT) per unit during night rate, I joined this plan myself. So the savings are even less compared to just calculating nearly the full production at full day rates. I'm all for renewables and for individuals installing big PV systems and using a lot of it yourself (have done it myself too), but we have to be realistic about the real savings in terms of money.

jordan191 · 19-03-2021 12:46PM

so after a bit of shopping around he's my best quote

5.7kw system, 16 no. 350w longhi pv panels, solis hybrid invertor, no battery storage with ground mount system , south facing, installed ( no grant available) for approx 7600 inc vat. I have a zappi already & an EV with large battery

I was looking at doing a DIY install, but the electrician quotes were all a bit too high after i bought the gear myself

Why a hybrid if you don't have any battery?

jordan191 · 19-03-2021 12:58PM

ah just to future proof putting in a battery
