Domestic solar PV quotes 2018

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?

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 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.

L24 = Nissan Leaf 24kWh BEV

lol, you just can't help yourself correcting it

7 out of 10. I've a good understanding, but certainly no expert! What can I say, I'm an IT kinda guy

10/10:)

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.
Thoughts

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.

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.

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.

Hi Wexfordman, would you be able to PM me the name of the company providing this system.
Thanks....
