I received the following quote, What do you folks think?

I am more inclined to go for the 16 panels with the bigger inverter. I also have an EV in case that impacts anyone's advice.

16 PANELS 340 WATT 5.44KW JA SOLAR 25 YEAR GUARANTEE.
5.0 KW SOLIS INVERTER
4.8 PYLON TEC. BATTERY.
I BOAST WATER DIVERTER.
WI FI DONGLE
10500 EUROS INC. VAT. Minus 3000 euro Grant = 7500 Euros

Or

12 PANELS 340 WATT 4.08KW JA SOLAR 25 YEAR GUARANTEE
3.6 KWSOLIS INVERTER
4.8 PYLON TEC.BATTERY.
IBOAST WATER DIVERTER.
WIFI DONGLE
9500 EUROS INC. VAT. Minus 3000 euro Grant = 6500 Euros

Looks good to me but interested in what the group think?

Get him to price the first one again, without the diverter and with only 1 battery (2.4kwh),that should knock about 1500-2k off it. You don't need 2 batteries and the water diverter is only a gimic most of the time. Add as many panels as you can fit on the "Sunny" side. If you can get that for around 6k nett you'll be getting a good deal.

Not sure it'll drop it by quite that much. The diverter that this installer uses (and I suspect its the same one you and I used) I believe is about €200 fitted. Losing the second battery will likely drop it by around €1k at most since he'll already be fitting 1 and the second is a 5 minute job to add so only really the value of the battery itself to come off.

Your initial post confirmed a high slant / pitch, so that will be a non-runner realistically. You could look now and see if your NE facing roof surface ever even gets any sunshine ?

And is your SW facing flat surface butwern any dormer bits coming out from the flat surface, which can throw shading on any part of where you propose to install panels ? You want a clear, unobstructed, view of the southern sun, for as much of the day as possible

Unfortunately there is a high chimney and a velux window on the SW face which will reduce the number of panels (due to shade and space). I will start looking at the NE roof over the next few days and see if it gets any sun. I also have a brick flat roof shed that I wonder could take panels. But it’s about 20 feet away from the house so would need cables running. I have another installer coming to do a survey next week, so will ask him too what he thinks about the panel situation.

Got a quote of 9k after grant for 6kw, 18*340w qcells, 5kw battery, 6kw solis inverter, still seems quite high to me when you consider the parts are around 6.5k doesn't it?

Still better than I was doing and if you think installer is most likely getting it better than 6.5k then that's 6k-ish for a day's work.
Maybe things might actually be better value when the grant goes!

If you are dropping down from 8 panels on the SW side. I might question if it's worth it?
How many would you get on shed roof? If it's flat could you point them at any angle you want?
Definitely something I'd consider....

So even after paying roofer & spark & profit cut, 12k (pre-grant )seems a bit on the high side to me but I think we're in the worst situation now.
Everyone rushing to install PV before grant goes out, installers are busy AF can turn down jobs if you don't like their high quotes
Can't see a lot of 12k installs once the grants are out.

Could be a great option. No reason why it cannot take them. You could put the inverter in the shed and just run an armoured electric cable to your board.

I have run DC cables from my house roof out the my inverters located in the shed, so there's no issue running AC or DC cables a decent distance

That's mad money if it's before the grant and probably still high if it's after it.
Why do you want 2 batteries with FIT coming in.? You would do better if you got rid of the diverter and put up more panels with the saving.
Sending you a pm.

That was the initial quote before even a survey/phone call, just on the email I sent.

It's before the grant.

I currently can only heat water from the oil boiler and have to fire that up just to get some hot water. Also have constant queue for showers (parents training each night and 2 active kids). Is it still advisable to shy away from the diverter?

rx8 · 07-04-2021 01:26PM

That seems like a lot of hot water there. The diverter will only start working when there is excess energy generated. So the 1st thing to charge will be batteries and then the diverter will kick in. Maybe don't bother with the batteries at all, the difference in the grant is only small. Your excess will then all go into the water heating and to the FIT, once it comes in.

When you use the oil to heat hot water, can you only heat the tank?

You'll not save money with a diverter, but there could be a convenience factor. Also depends on how deep/position of the immersion is, how much of the tank it will heat.

If you go into this knowing that it's hard for the diverter to pay for itself, and your getting it for convenience, it's up to you to judge if it's worth it.

Eg my parents. Have a hot water diverter, got it for the summer, so they don't have to keep a fire ticking over for them to have hot water.

Theoretically we should be able to heat just the water tank, in reality, it heats the rads on the way to the tank too.
2 bedrooms, bathroom, and walk-in

That then could skew things a bit in your favour, in summer.

I'd look into getting a smart heating control with smart TRVs too

Family of 4 here, myself, wife and two teenage daughters with long hair so high hot water demand with minimum 5 showers a day.
So far in April I've let a lot of PV go to the water i.e. 78kWh and as it's all done automatically, there's no flapping around with switches etc.
Also it is better to consume your PV before letting it go to battery/grid etc.

Hot Water Diverter is probably financially flat over it's lifetime (as depends on install cost and how long it lasts) but it is very convenient and a lot better that burning fossil fuel.

All week we've had plenty of hot water, all from the sun

A quick FYI on this point. The SEAI now has an online application where the homeowner just has to submit MPRN, house location and select their solar installer from the drop-down list of SEAI approved installers. The confirmation comes straight away and then you have 8 months to get the installation completed and BER cert.

So best to get that done as soon as you've picked your installer.

The site to register your solar grant claim is here: https://mgen.seai.ie/

slave1 · 07-04-2021 05:08PM

I actually thought it was 6 months, 8 months much nicer.

Solar installers are busy because this is the season for it, lead time much less Oct-Feb

DrPhilG · 07-04-2021 06:05PM

I confirmed my order in early July. Installer had me live before the end of the month.

Not bad but the inverter is too small, reprice with a 6kw Solis invertor. The price difference is very small.Better to be looking at it than looking for it.

Very true, thank you. I'll get back onto them and see how much extra that wil be.

SD_DRACULA · 08-04-2021 09:52AM

Yeah it's a good quote before grant for sure, I got quoted 5k after grant for similar, so 8k

Not bad, you have a Harvi included, see is it possible to run some Ethernet cable instead, hard wired will always be preferable and is also permanent.
The cables need to run from PV and Grid feeds back to wherever your are putting your EDDI hot water diverter.

Thanks for that, I'll mention that to the installer. I have ethernet pulled into most rooms and empty ducting so no hassle in using them over wireless

If no ducting then a TPLink EoP be suitable?
