Domestic solar PV quotes 2018

wexfordman2

Hi,

Thinking this might be a worthwhile information point and reference.

Good to get an idea of prices, and see if the recent grant is causing anomies etc.

If anyone cares to post up quotes they got (but excluding the company/supplier to keep mods happy).

We should show quote if system dimension, something along the lines of

4kw solar with 5kw battery and diverter 9,900 ex vat
5kw solar with 5kw battery and diverter 11,200 ex vat.

Additional info
This was for a "premium" solar panel with 30 year warranty.

Provider is seai registered, so grant is apicable, and he claims HRI/vat refund available also, however I believe thats an error.

Payment terms
20% on order
Additional 50% prior to install
Remaining 30% post commissioning

Quite for market standard panels as follows

4kw with 5kw battery 8750 ex vat
5kw with 5kw batter 9750 ex vat

So what are you doing with the excess?

Be much handier if we could just feed it back into the grid rather than buy batteries

One neighbor has a very old meter and it runs backwards, so they are quids in

I have a very old meter that runs backwards, anyone know what is this likely to mean for billing - given that I will appear to have used very little electricity from grid?

I've used all sorts of EVSE's from all different manufacturers including high end ones in work and I have had issues with them all! Including having to send a chargemaster back under warranty. Surely Zappi can't be any worse?

I've had issues with my own Rolec. These EVSE's, for whats in them, are way too expensive. I dont think the Zappi is any better or worse (reliability wise) than any of the others but its early days for Zappi. They are not on the market as long as Rolec.

Also the Zappi instructs the car via the communication wires on what amperage to charge it, so it in theory can go below 2kw, how efficient that is though I don't know!

Thats car dependent. Not all cars can go down to the 6A minimum (1.4kW) that the protocol allows.

Strictly speaking you are supposed to tell ESB Networks (via an official form) that you have Solar PV. Did you do that?

If you did, its their own problem as they own the meter and it would have been up to them to change the meter to one that doesnt spin backwards.

If you didnt, you are breaking their rules and can sanction you with disconnection... I doubt they would do that but they would be within their rights to do that.

As long as your usage doesnt go negative you'll probably be alright.

I would love to give it a test and see what it's actually like data wise. Are there any boardsies out there with 5kw of solar and a Zappi charger?

Good advice.
I advise you to call ESB and ask for an immediate upgrade to a least digital meter.

Cant say too much here, but I have been sending to grid KWh and being charged for... can't say but i lost those KW,i paid for them.
Even if ESB have been notified... i got replaced the analogue spinning meter after 3 months of being double charged with a digital one.

I have PVs and L24 EV and a car charger (not Zappi) and i can confirm is charging at minimum 6As for as long i setup the charge from the mobile app. Graphs above top of the page,again thanks to @unkel for ideea.

But,i have in mind a second car / second different charger and really love to see how zappi performs in real life... but nothing visual yet...

What you have done with your charger via your app is not alot different to what the Zappi does, except it does it automatically.

You have to manually change yours according to each charge session and as the clouds roll over etc. The Zappi senses it all in realtime and does the EXACT same thing.

Im not sure why you need graphs or proof of the whole thing. Its the same as what you are doing manually yourself.

Whether it works in real life is down to the individuals circumstances (is the car at home and is the sun shining). A graph of it working for person X wont change those two things for person Y.

By L24 do you mean 24kw battery leaf?

If so show me how you did the charging at 6a. it's not available in my app!

He's talking about an app that comes with his charge point, not the Leaf app.

So, the charge point limits the rate to 6A regardless of what the car asks for.

I was the same.
We shall drill it into you.

When you say kw on its own, that is a reference to the power of the motor so you can see how it could cause confusion to other lurkers looking in on the EV forum.

I know is not linked to my smart meter readings but since i changed the EV charging habit...i got 10KWh per day,thats 10 in a day,10 in other day...10 KWh per day,and mostly at night,what, thats like less than €1 a day !?

Car topping up in the afternoon 100% on the PVs and very little over night at reduced rate.

Complete ZERO consumption for whole day and that is from a ESB sealed meter type... cannot say "too nice" for the environ but lovely for my pocket.

Now,whats next...hmmm

Alkers

We've just our first quote in:
8,150 after grant for ten 300w panels and two 2,400kwh battery storage.
As above but one battery only 6,900 after grant.
8 panels no battery for 4,800.
We have a night meter, approx 40% use on night rate, no one at home during the day most days. Typical usage is about 10kwh per day but this has increased recently since we got an Ampera PHEV which we charge at night right but is sitting in the airport two or three nights a week.
South facing roof in d12, good access from extension roof to main roof.
Installer reckons 600e per year saving with the first setup above. We'd be happy with a 12 year ROI but would be hoping not to have to spend 8k.

He's bullsh1tting you.

A 3kwp south facing system in Dublin will generate about 3MWh per year. If you use every single unit of that for something that could not have run at night (like your car or the washing machine), and nothing goes back to the grid for free, then your theoretical maximum saving is:

3000 kWh * 18c = €540

Your real savings are probably more like €200-€300 at the very best

That sounds a little bit on the high side to me but maybe it is using high spec LG panels and battery.

I have a 4.2kw solar PV and a 4.8kwh of batteries and it came in a nice bit lower.

I'd try a few quotes and if they all still come in the same go back to the one you like most and ask them if they can do something on the price for you.

It sounds high simona , they love to quote after grant which is annoying,and just think about it the grant technically is between you and the Seai and nothing to do with the installer in reality.!
The batteries are a big cost on these I have found . I have 2 quotes in and waiting for a third and it is looking like it is more cost advantageous to go without the grant believe it or not .
My advice is get a few quotes and see where you are then .
Best of luck

Holy crap, thats 11950 for a 3kwp system and 5kwh battery, way too pricy. I got a 6kwp system with 5.6kw inverter, 5kwh battery and hot water diverter for that price.

A benchmark price from one company at the moment, is 10,500 inc vat and before grant for a 4kwp system with 3.6kw inverter and 5kwh battery, so the end cost after grant is 10,500-3,800 = 6,700. (using qcel panels, and good quality hybrid inverter/battery system)

That should be the price you are looking to beat. Your system above is 1400 euro more expensive and only 3kwp instead of 4.

Very expensive I think.

Good man, well done.
We're you tempted to go for 3.9kw or 4.2kw to get max grant?

you got me thinking and i ended up changing,

3.6kW enphase, my eddi immersion, 2.4 KV battery, pretty much max battery,

garo

Agree that quote sounds too high Simona. I have had 5 quotes so far and for 14-16 panels with battery and diverter they range from 7k to 8.5k net.

I would definitely go with a single battery instead of two if you had to go with this person. Think about it this way. It is costing you 1250 for a 2400Wh battery with usable capacity of 2200Wh. It has a rated life of 6000 cycles so you get 13,200 KWh. At the 8c night rate it will cost you 1,056 to get that energy from the grid. And that's assuming you are able to fill up the battery fully on each cycle.

I have a pitched dormer roof on my house, which covers a lot bedrooms. Are there legitimate health or safety concerns about mounting PV panels over bedroom areas where the panels would in some case be no more than 2-3m from children's sleeping areas?

No, no problems and no safety issues at all.

One megawatt hour produced since my current system was installed in February. Not bad :cool:

System is expected to produce nearly 4MWh per year. The average Irish household uses 3.5MWh per year

Aye, but it's not all during sunshine hours. Our annual usage is approx 3.6Mwh, of which 52% is consumed at night.

Indeed, Mr Spoilsport

Most of my production is going straight back into the grid, gaining me nothing. For the greater good. Reducing our overall emissions and reducing the fossil fuels we are burning to produce electricity. If only every house and every office building would produce more electricity from solar than they use, just like me...

I have got a much more reasonably quote since (although for a smaller system) so I'll update this thread this evening
