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

@wexfordman Do you have a clothes line out the back. This would save you using the dryer as much. I find i'm using the line and just finishing them off in the dryer for half an hour. I'm soooo domesticated these days , constantly doing the clothes wash and dish washer . My wife thinks it's brilliant:D

They should advertise solar PV as a labour saving device for the ladies:D

:-)

But if we use the clothes line, we waste all that free energy. I think the drum might wear out actually :-)

One more quote:
4.2kW power 14x300W panels
Solis 5kW inverter
Pylontech 3.5kWh battery

7,000 after grants deducted and VAT added.
Battery can be upped to 5.9 for another 1000.

Could you PM details of your PV supplier please? Thanks

What monitors are good to monitor to put on a system to see the energy usage in the home? One that's WiFi enabled and is decent to view on a home network?

Is anyone diverting to unused solar leccy to heat the hot water say instead of using a battery for the excess?

How would that works vs say solar thermal collectors?

You mustn't have read any of this thread. Lots of people are doing it, a lot of people are doing both, filling the battery first and then diverting to water. Only thin is that the payback on diverting to water is long as you need to divert 4mwh just to break even on the diverter!

Indeed. But it's more like 10MWh before break even. One kWh used to heat water with gas or oil costs €0.05

A diverter costs about €500 installed

500/0.05 = 10,000kWh

Nice day for the solar anyway. For hours on end I was producing >3kW today. In the next few days I'm coming up to 1MWh produced in my 3.8kwp system that was only installed in February :cool:

Evd-Burner

The quick maths have failed me today ðŸ˜

NoBread

How does the system cope during a power cut? Had a couple recently and was wondering. I guess in both scenarios, one with a battery system, and the other without. Assume a bright sunny day in both scenarios and mains power gone for 3 hours!
What happens if the draw exceeds supply?

Decide what you want to do / how much you want to spend. And then just bite the bullet, Aiden. I doubt you'll regret it and you'll be doing the right thing. For yourself and for everybody else.

Yep you are right. So many good reasons to do it.

I don't have a diverter yet but today on the way out to work I put the Immersion on bath and left it on all day (I know, crazy or what) .. didn't use anything from the grid. Came home to full hot tank of water.

Wouldn't do that normally, twas just an experiment like

4.2kw east/west PV with 4.8kwh Pylontech batteries.

gally74

Signed today. 3.6 kw solaredge

I like your style niallers1. In a similar experiment I'm going to charge my EV from my solar from about 10AM tomorrow and see how that goes

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

not really, im getting a 5K inverter and will expand when a FIT some in in 2021, i initally was going for a battery but if FIT does come in and i think it will, it will not return the investment,

i also got the solar edge imersion setup etc. We have activity during the day in the house, so consumption should be high enough,

secondly we used oil for heating the hot water during the summer, the burner is located in the garage about 12m away from the house, so quiet inneficiecnt to heat water in the summer,

iits not all about the money here, its the right thing to do,

as the king once said, "The time is always right to do the right thing"

What’s the plan, connect via granny cable?
Can the Ioniq also set the granny cable to the min of 6A?

That combination would be ideal.

unkel

Just plug in as usual with my EVSE. End point of my charging cable is literally centimeters from the charger in my car for maximum convenience. Why would I bother using a granny cable?

Limiting the current from within the car alright. Can't remember what settings I have, but I know the minimum is 6A. Currently the base load of the house is about 1.4kW so that would be ideal if like today I will produce >3kW steadily for hours on end (tiny bit hazy now and then but no clouds), so I should charge 100% from PV and 0% from the grid

rolion

You will not be able to fully charge from PV...you lose the money compared with charging at night rate.
The Sun will not stay up there and "wait" for the car to fully charge, it will be covered by clouds and that alone will fluctuate over the couple hours and few minutes. Been there,done it and i say it never do again but .... well,i hate sometime giving the free electricity to mr grid.

@Gally... on this land we will never get the FIT you are talking about.
No offence intended, but plan your system around maximising consumption and in-house efficiency.

Not necessarily. On a cloudless (but slightly hazy) day like yesterday, where my production was a steady >3kW for hours on end without dipping below it, I could have charged my car at 6A or even 10A without ever buying from the grid. No, not from 0-100%, but I think I have only ever charged from 0-100% once in the well over 2 years I have the car...

And even on a mixed cloudy / sunny day if you charge say two thirds of the time on PV and one third of the time you have to buy from the grid at the expensive day rate, it is still cheaper than charging at night rate overall

You know what...i owe you a nice bottle of Maynards's Port !

Just went in to my mobile app for my charger and found that i can adjust the charging rate / output amperage !
So, if i can setup a timer to start charging when car arrives at home and stop charging when i feel the appliances will start the work,i can use the PVs to feed a steady 6Amps / 1kwhish to my battery RATHER than free to mr grid bonuses !!!
Then,readjust it overnight if necesary,back to 16Amps.

That way,the diverter finishes its work and cylinder hot by lunch time so the excess 10KWh afternoon rather than "wasted" in bonuses goes in to MY battery !
Oah,it's amazing if that will work...

Glad i read this - long time reader first time poster!

i'm getting quotes in at the moment. my intention is to put in solar pv, divert excess to hot water (which in itself will rtequire a new HW cylinder) and, going forward to charge the electric car that i reckon will be purchased in the next 12 months (waiting for me diesel to die...)

i thought with one of those fancy zappi chargers i'd be good to go with EV charging? the car is left at home twice a week so could daytime charge.

thanks to all have you that have posted useful/interesting information here.

Not quite sure about the Leaf, but in most EVs you can adjust the charging rate / input amperage from within the car too!

The min for the charging standard is 6A but I believe some cars dont accept a rate that low.

I dont know what settings the Ioniq has but it might be better to use the granny charger to get the lowest Amp setting possible..... if you can use your 32A EVSE but limit that to 6A in the cars settings then thats perfect too.... as I said, I dont know what the Ioniq menus allow.

Does it just have one setting regardless of whether its the granny cable or the 32A EVSE?

Not configurable on the Leaf menus.

It really isn't worth buying a diverter and a new hot water tank just to divert the hot water. It will take years just to pay off the diverter, nevermind the tank!

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

im playing from within the charger' mobile application... setting the minimum charging current. Waiting for the LEAF to come home...
Issue is what if i forget to up it back overnight ?
