To be fair, I've a small roof so if I go for one side that would be it done I'd imagine.

Anything I do I have to keep in mind the ability to add a velux somewhere (ideally at the back).

Thanks @deezell - that and even actual solar tiles might be options, albeit more expensive (once I get some prices!).

I'll put the quotes in here if I get them.

The ones I saw only had 4 panels in the centre of the roof probably the minimum required for building regulations, there certainly was plenty of room on the roof for more panels but they'd look terrible around the inbuilt ones.

For sure having them on the main roof is best for shading - as you say

What do you think?

Salesman from ******* gave a price of around €6K for 5 panels on the extension, he also mentioned the main roof tiles as a no go for panels.

Messed around with model here to see if that makes sense for what it costs v it can earn especially as I have noticeably lower bills than many (as low as €80 in summer up to €160 last year before the refund scheme).

https://pvwatts.nrel.gov/pvwatts.php

Overall I think I'm out of the running until I find someone willing to install on the main roof or otherwise wait until that needs to be updated and do something then.

Also, for anyone else in a similar situation shademap.app was quite useful as it generated a fairly accurate 3D model of the houses in the area that casts shadow and gives the expected annual sunlight hours as 1055 on the extension roof. Roughly a quarter of the main roof at 4272. Neither would be 100% accurate as the app doesn't put an apex on the roof so I'm sure it would drop the sunlight hours with that.

Modnote, no naming installers

graememk

Thats very very expensive.

Did they give any reason for not installing on the main roof?

Try a few more installers (we have a list pinned that people here have used, list is not exhaustive, but a good starting point)

WildCardDoW

Three installers so far have said they won't install due to 70ish year old rosemary tiles.

Basically small and brittle tiles from what I've heard.

They basically rule it out as soon as they see them. I assume it makes the install harder or riskier.

Borax2709

16 panels - 6.9 kWp, hybrid invertor and maybe 5 or 10 KwH of storage.

Flat roof - 3 storey so ballast/flat roof installation and cherry picker probably adding some cost.

No grant as house 2021 build.

10.5k with no battery

12.5k with 5

14k with 10

Have had 2/3 quotes all in and around this price. Feels kind of standard? (Dublin based)

graememk

https://www.boards.ie/discussion/comment/122446655#Comment_122446655

Ah yes I remember your other posts now.

Honestly I don't blame them, old tiles can be very brittle, practically irreplaceable. If they went up and even if they were very careful and still broke a tile, they'd be responsible to fix it

And I'm sure you don't want to replace your roof either!

https://www.boards.ie/discussion/comment/122446441#Comment_122446441

€6K for 5 panels sounds like a 'someone actively ate your cash' quote alright.

You should perhaps try talking to a builder/roofing business with a view to a solution for either fitting the rail hooks, or else sinking a waterproof space to carry in-roof panels. It wouldn't be that difficult to just replace the problem clay tiles with flat conrete pantiles, in such a way that the solar panels will cover the changed tiles. This would give you a robust base to work on under the panels, and a large stack of spare clay tiles should any of the perimeter ones break.

Installers are one trick ponies it seems, just interested in the in and out cash cow work, no problem solving additional skills beyond the basics. Talk to some builders/roofers about getting the rails up, in-roof frames, or just retiling the target roof area. It will cost more no matter what the solution. Just check also that you won't fall foul of planning by altering the visual character of the roof, It sounds like it could have architectural heritage issues if all the roofs have these ancient pretty tiles.

Are these all a standard size, the reas9n I ask, is if I wanted to swap my existing panels for these, is it mechanical straight forward?

WildCardDoW

https://www.boards.ie/discussion/comment/122447331#Comment_122447331

Yeah, a quick Google shows some specialist equipment so it seems like they just don't like to bother.

Onto one last crowd here ha.

Got a quote from that Flogas offer after survey,happy out with it so far:

-5k for 10 panels and 2 optimizer, no battery + hybrid inverter , they look after the BER now aswell.

Will report back when finished as going with this.

Question for those who have, or have considered, an Eddi diverter.

Going for a 8kw set up with battery (19 panels). Reasonably high energy consumption household, particularly as one family member works from home. I like the idea / concept of the diverter and our old(er) timer / boost control leaves a lot to be desired, however, depending on needs I have been seeing mixed opinions about the current need / sense in getting a diverter given one can now sell back to the grid.

I don’t mind the initial outlay on the diverter, so more so wanted to check if there is any meaningful drawbacks to having the diverter such as the extent of savings (and based on the assumption that rates offered for buyback may also diminish over time) in otherwise selling back to the grid. Or is the consensus that they are handy to have?

When do you need hot water?(AM or PM,can you get away with heating tank at 7am) have you a good insulated tank? (that will last longer). All questions like this are dependent on your own situation.

danb_2010

https://www.boards.ie/discussion/comment/122458157#Comment_122458157

Thanks for the reply. Need hot water AM (6-7am) and PM (6-8pm) due to a few in the household training / playing sports in the evening. Tank is reasonably well insulated. Currently operate / rely on a timer daily around / before the above mentioned times to ensure adequate hot water.

reggie3434

in same situation but going without the eddi and upgrading the immersion switch instead (currently have a switchbot which can be unreliable)

I see the eddi as another device to manage and don’t need hot water all day

danb_2010

Thanks for the replies. Appreciate it.

Last question from me (which I’m struggling with) and not looking to open a can of worms on the whole smart meter vs standard day/night meter debate, but for a system size of 8kWp (19 panels plus 5.3kWh battery) with estimated 50-60% usage, would it make most sense to switch to a smart meter in terms of exporting back, or would a standard day/night metre with say a 21c per kWh microgen rate and using ESB’s Deemed Export Quantity be sufficient, or would I be leaving “a lot” of money on the table by not having the smart meter with accuracy on exporting figures?

graememk

https://www.boards.ie/discussion/comment/122460277#Comment_122460277

No deemed export for new installs

There is a smart meter replacement for the Day night meter now, you can stay on your standard plan as normal and get measured export.

danb_2010

https://www.boards.ie/discussion/comment/122460735#Comment_122460735

Ah ok, this is good to know. Thank you. I’ll get in contact with ESB ASAP and request an RM108 installation.

Presumably upon install the standard microgen rate offered by my provider for non-smart D/N plans will then kick in but based on actual export figures?

graememk

https://www.boards.ie/discussion/comment/122460898#Comment_122460898

The microgen rate is the same no matter what your plan is (within a supplier)

We don't have dynamic pricing yet.

Nolars

Does anyone know if it's possible add a ground mount system with an existing roof installation? Only space for 3 more panels which would bring the system up to 5kw so just wondering if a ground system would make more sense.

Graememk. Just wondering was it you that answered my post a while ago about heating my existing radiators with PV solar panels heating a separate copper cylinder. If so you mentioned using a Deye Inverter. Have you any Idea If that Inverter is suitable for use In Ireland please. Thank you.

graememk

https://www.boards.ie/discussion/comment/122469236#Comment_122469236

Deye and sunsynk are the same inverter.

for use in ireland, as long as you can get the correct certs for it you can use it on grid, (certs are for the NC6)
deye certs are here https://www.deyeinverter.com/product/hybrid-inverter-1/sun3-3-6-5-6ksg04lp1-3-6kw-single-phase.html

sunsynk certs are here: https://www.sunsynk.org/product-certifications
as for what your doing, Ive done it.. Back when i had a 5c night rate!
https://www.boards.ie/discussion/2058250939/water-battery-20kwh-of-extra-storage/
I have since moved onto a heatpump, (can still use the buffer tank as storage even with the HP)

newtosolar

Graememk, Thanks much obliged for response. My Idea was to be completely separate from Grid just to heat my Central Heating rads as best I can In winter. To have a changeover switch to heat my DHW Cylinder (summer time) for when plenty of power coming from Solar Panels. To have a socket as a standby where I have a Grid outage. ALL separate from Grid. If you live In Ireland have you used the Deye/Sunsyk Inverter and You happy with It. JS.

Is this their "4 kWp solar offer and a post works BER for only €4,800" offer?

Any further feedback on Flogas - who installs, lead time, any negotiation etc?

Did you price around?

Do you get to keep the BER for future use or do they have exclusive use of it?

danb_2010

For those of you who use Flogas for your Solar system, just to check is their 20c microgen rate for both the Certa and BWG affinity plans or just BWG? Looking at the offer pages, the BWG (which ends in March 2025) references the microgen rate of 20c, whereas the Certa page doesn’t make any reference at all to microgen rates. Thanks

graememk

https://www.boards.ie/discussion/comment/122478014#Comment_122478014

The ber is part of the grant process, so I'd say you'd get to keep it, as they have no use for it.

The accessor will publish it to you and to whoever is processing the grant application.

reggie3434

yes that’s the offer, 4/5 weeks lead time and the partner of Flogas install using own staff.

priced about 5 different companies so far and this the best, no haggling as already getting sub from flogas

had one installer quote 3.5k more (there was 2 more panels) and scoffed at my estimate of 6/7k, they were using a pool of panels ( again didn’t inspire me) and the extra cost was because of the great support/brand name which was the third strike

just waiting on sorting a job in house before paying deposit
