Domestic Solar PV Quotes 2020

Bloody hell...



This sums up the problem. There are people charging a reasonable mark up to make a profit. And there are people taking the absolute piss.

I got a quote of €9600 for a 6.24kw array inc. solis 5kw inverter and a 2.4 battery. This price was after the seai grant

I got essentially the exact same thing, for €3k less.

Is 6.8k for 4kw panels and 5kwh battery decent? That's after the 3k grant.

Hello all.Currently considering solar pv for a newbuild with a2w ufh.
Have received the following quotes for supply and fit including commissioning etc. I would be interested in any feedback or recommendations.

1- 4.68kp of modules kitted to 1 x 5.7kWh battery storage
12 x Bisol Premium 390w Monocrystalline modules (All black modules)*
Bisol Mounting system on a Natural Slate roof
Alpha 5 kWp Inverter kitted to 5.7kWh storage capacity
Price: €8810 + vat = €10,000

2- 12 no Solar Panels 375Wp totalling 4.5kWp
Inverter, hybrid, with data/wifi card
Price: €6,780 + vat = €7,695

Increased size: 5.5kWp (14no panels)
Price: €7,460 + vat = €8,467

My Energi Eddi €620 + vat including installation

Lithium-Ion Battery Storage Option:
2.4kw €2250 + vat
4.5kw €3310 + vat

3- 14 x 325W Peimar Panels totaling 4.55kwp photovoltaic system
1 x Solis hybrid Inverter
My Eddi Hot Water Diverter
Price: €7,420.00 + VAT = €8421

4- 12 of 375 Watt Mono Trina PV Module
Huawei hybrid Inverter (battery ready)
My Eddi Hot Water Diverter
Price: €7056 + vat = €7,974

I read a lot of posts saying the hot water diverter doesnt make economic sense coupled with heat pumps.
Without battery storage or an EV is solar pv worthwhile at all given the expected low return on FIT?

Hi all,
Looking into a PV install but like many getting a bit lost as to whether it's worth it. More accurately at what price does it become worth it?
I'm in a refurbished to some extent old bungalow. There is a gshp for underfloor and radiators and a separate tank for domestic hot water heated by a clip on heater when not enough energy collected by 3 thermal solar panels.
We use way above average for electrcity as a result. About 15000kw (not a typo)
We have a day night meter and coming to the end of contract.
Had a couple of ballpark figures of 8-9k after grant for a 5.5kw ish system split between SE and SW. With a battery 2.4kwh.

The only official quote I got was 9900 for 18*320w panels on the se side only. And a 5kw inverter plus battery.
Seems crazy high to me and has put me off proceeding.
Got the feeling they wanted an easy install and were not to keen to split it so I might get some more of the later day sun.
Anyone have any Se/SW splits about 6kw that could share their experiences I would love to hear
Thanks

Don't have a heat pump system so hard to comment on the diverter in this case but I think they probably never make economic sense but certainly I like the convenience of my one giving me hot water on demand without having to turn on anything etc.

But I would imagine that with the extra year round electricity use that heat pump systems entail with the recovery / ventilation systems solar panels make huge sense.

In the winter they will help only a little for sure but in spring an autumn when you're still using heating I would think you would make good savings. Plus, you have all the other uses - cooking etc. For instance, last three days I've used 1.2kwh (units) of electricity in total. That's all lighting, cooking, toasters, coffee maker, tv, computers, networking run for 'free'.

Plus, come July the FIT will mean you make some money on surplus.

And finally, there's the whole carbon / green argument

As the Dr says - not terrible but probably a bit more could be haggled... I got 4kw panels plus 5kw solis hybrid plus 5kw battery for 7950 before grant).

That is the same quote I got for 4kw panels, 5kw solis inverter and no battery so it is very good.
Assuming JA panels or equivalent and pylontec battery?

Qcell G8 split cell 340w panels. Puredrive battery. The Puredrives have 2x max power output compared to the pylontech so was happy to go with them as recommended by the installer.

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?

Well that's a lot better than I was doing. I got quoted 3k more for a similar option to your first but with no I boost and half size battery. Slightly more panel in my one but that offer is tempting to me.
Still looking here and maybe the itch makes it look inviting and others will tell you that you can get better but I certainly wouldn't fell I was overpaying. But then I haven't spent anything. Yet!
Ground or roof install?

It’s a roof install. I have a dormer house so the roof has a quite a high slant/pitch. The panels will be split between both sides of the apex. The front of the house is south facing but since it’s a dormer, the roof runs east to west , if you know what I mean.

Yes I think so. 8 each side?
I tried that website for pricing up stuff yourself. Solartricity.
Came to about 5k for what I was thinking of. So assuming installer pays approx 20 percent less, that's 4k spend on a 13k quote(before grant). They were taking care of grant! 9k for a day's work for maybe 3 or 4 lads.
The more I write the more I realise how crazy my quote was!

BopperSnr wrote: »

yes 8 panels on each side. I do think it sounds like i have a good quote that I should proceed with. Your quote sounds way too high now.

I'd definitely be tempted but wait til others reply. You definitely don't want to be comparing to my mad quote.
The first option seems better too. 4 extra panels and a bigger inverter for 1k seems good? However if you're directly e/w then maybe you only need the smaller inverter?
Or when/if you need to replace it. The 3k Inverter would do?
Actually does the battery size determine the inverter? So many questions.....
