Domestic solar PV quotes 2018

Don't forget that depending on the inverter you can also charge the battery at night time an dissipate during the day. I worked out an additional saving of €85 a year based on 4.8kwh worth of batteries.

Here 8s a link to specs.

Mine is installed in attic just above stairwell, all wall mounted

Yep looks like 60A charging for the whole range from the smallest 2.5kWh battery to the biggest (yours) at 5.6kWh

For the smallest one that still represents less than 1C charging. My EV can charge at nearly 3C and has a lifetime unlimited warranty on the battery in the USA. So 1C seems more than safe and I doubt temps will be an issue with an indoors install. Another big plus over the Pylontech batteries imho

No mention of any EN50438 in the certs section though, which is "interesting" as it was installed under the SEAI grant scheme. You did get your grant back already, did you?

Keep us updated!

My bill annually is approx 1600.

If I spend 7 to 8k net on PV, the payback based on SEAI is heading way over 15 years.

What am I missing here?

What size system is that for.
Would think that you would half your bill so that would make it about 10 years not allowing anything for the usual 5% increase in electricity prices each year.

4.2kw PV with 4.8kwh lithium batteries should cost about 6k net of grant.

Heading towards 6kw, 18 panels and 5.6 in batteries.

SEAI must be selling themselves short with that calculator?

Guys would it be an option to have some tubes for hot water and then PV for power?

Would a diverter/ inverter be needed in this case?

Of course you can! That's what I have.

Tubes system is worked by a controller that checks temps on roof, on bottom of cylinder and on top of cylinder. Based on various settings it decides to turn on the pump that takes the heated glycol from the tubes through the cylinder to warm up your water

PV panels are connected to an inverter that is connected to the grid. A bit over the top, but you could still install a diverter that heats a coil in your cylinder if you produce more electricity than you consume

Can you give us a breakdown of your setup and cost?

whats the payback on the tubes heating water?

I've a 40 tube Kingspan system installed in 2016 by an SEAI approved installer. After the grant I paid net 4.7k for this, including the retrofitting of a 360l highly insulated Joule cylinder in my hot press

We're a family of 5 (4 females) using lots and lots of hot water. If you don't use a lot of hot water, I wouldn't bother as your payback will be long. Mine isn't long. I needed the big cylinder anyway as the standard 120l was empty after a 10 minute shower (with our 3 bar water pump). Well under 10 years even taking into account maintenance

As for my solar PV. That's the opposite. I've done part self installed, I paid a roofer for a days work and a friendly electrician installed it for free as a favour. I sourced all parts very cheaply. It's a work in progress, I don't really know what it has cost me so far. I would have to spend time to add it all up. Suffice to say that I spend quite a bit of time routing through forums and eBay for bargains. And all the earlier bits I have used, like panels and inverters, I have since sold for more than I paid for them.

Hi all,
First quote the other day which I think a bit high, what do ye all think?

I have east west split , 1050 sq ft 3 bed semi d, 140 Litre hot water tank and gas boiler can heat rads and water.

Details were-
10 x Denim 300Wp All-Black Mono Crystalline PV Module with 35Years Production and 35 Years Product Warranty. i.e 3kW system.
• 1 x Solis 3.6kW Single Phase Grid Tied Hybrid Inverter
• 1 x 3.5kW Pylontech Li-Ion Battery
• 1 x 3.0kW Power Diverter (For Hot Water)
• 1 x Santon Fireman Switch
• 1 x Electrical Materials, Fuses, etc...
• 1 x Full Install, Grid Commission and SEAI Grant paperwork’s handling.
• 1 x Solis Wifi kit and Free Solis Monitoring portal for Life.
• 1 x BER Assessment for SEAI Grant + 5 Years Labour Warranty


7,100 cost to me incl vat and net of grant.
Only way this can stack up is if materials really top notch I think.

Denim are Dutch made PV panels.
BER should cost about 150-170 euros . Diverter depends on brand but could be between 400&600 euro. Is the Pylontech battery size correct?
Solis Dongle is about 60 euro and the santon fireman's switch is close to 250-300 I think.
Pylontech normally 2.4kwh per battery but I've just googled and see they do in fact do a 3.5kwh battery. This must be new. Very interesting.

To me it sounds a bit too expensive by a few 100.

It’s actually your installer too niallers, I thought prices might’ve gone up since you took the plunge but I see from recent posts they are giving better quotes than what I got even in recent weeks so I may get back on to them. Thanks.
I also googled the batteries and very little price difference between 3.5 kW and 2.4 kW it seems.

I noticed the spec seemed similar to mine. My quote didn't include the BER and diverter/ Installation of diverter so to that might account for the extra.
I had also asked(nicely) if they could do something with the price as my initial quote was higher than my final price.
