Hi people, really confused and badly needing advice here.

Quick intro on house needed, it's got a slate south-facing roof, however it's split level, the smaller portion of which would experience partial shade.

Got 4 quotes from seemingly good reputable companies, each of them so different in price and advice.

Company 1 proposed 6+2 panels, with optimisers on the 2.

Company 2 proposed 6+3 panels, with optimisers on the 3.

Company 3 (the only one that quoted without visiting, just from pictures, but did ask for photos and had a thorough chat on the phone) proposed 7+3 panels and only mentioned maybe 1 optimiser after I asked them about it.

Company 4 proposed just 7 panels on main roof, consultant saying that he could sell me the extra 3, but it wouldn't be worth it due to the partial shade, and when asked about optimisers, he was against it in our case.

Quote 1

8x415w Trina panels (3.32kw)

Huawei Hybrid Inverter

Mibet Mounting & 2 Optimisers

EDDI Power Diverter

€6,400 after grant

Quote 2

9x430w Denim panels (3.87kw)

Van Der Valk mounting system,

Eddi

3x Huawei optimisers

BER assessment.

€7,400- net cost after grant

Quote 3

10x435w Jinko panels (4.35kw)

Solis 5Kw 4G Dual MPPT Inverter

Eddi

€5,979 after grant

Quote 4

7x435w Jinko panels

I have an 18 panel ground mount that I did myself. They are more expensive.

Few questions:

is that including the mounting rack? What about concrete footings for the mounting system?

How far do you need to dig? Make sure you install the propper red conduit for the DC cables between the panels and the house.

delending on the distance you should be using 6mm2 cable rather than the standard 4mm2 cable to reduced the voltage drop and minimise system losses.

Drop the eddi and focus on exporting while the going is good. Anyone can install an eddi at a later date.

Mywifetoldme · 02-11-2023 12:20am

hi HotSwap,

as far as I know, which is very little, we have to supply the blocks and get someone else to do the groundworks ourselves.

I would like to get someone thats does everything

It's a good distance to dig, as the bottom of the garden gets the most light.

I've other people coming to have a look, hopefully in the next few days.

https://www.boards.ie/discussion/comment/121313373#Comment_121313373

on the rough guide of the quote analyser http://davidhunt.ie/solar/ its good,

Id seriously consider ditching the eddi, and check on the inverter, is it a sofar? If so is it an EP or ES? the EP has a higher discharge rate from batteries.

Gumbo · 02-11-2023 1:06am

https://www.boards.ie/discussion/comment/121313426#Comment_121313426

David seems to approve 😂

It’s not my install. Family member.

I’ll get the full details in the morning.

We couldn’t get anywhere near that price from actual installers in Dublin at the moment. The closest was €7700 after grant.

Eddi is only €500 so be mad to say no at this time as they’d never be able to get the hot water divertor installed in the future at that price IMO. I know I really like my Eddi if even for that sense of free hot water!

https://www.boards.ie/discussion/comment/121313345#Comment_121313345

I’m not sure why you would need blocks. Maybe they are being used as ballast to weight down the mounts. I would avoid this type of mount; and go for something more permanent (ideally mounted on a concrete base). Ask them all to specify exactly the ground mounting system they plan to use.

Mywifetoldme · 02-11-2023 9:27am

A neighbour has blocks as ballast, I can't remember if they have a concrete base.

What do you think about the price?

HotSwap · 02-11-2023 8:54pm

https://www.boards.ie/discussion/comment/121313798#Comment_121313798

Well you can’t have a 6kwh inverter anymore; so get them to include an inverter that’s allowed by ESBN and it might drop the price a bit.

Also it’s impossible to say if it’s a good price or not without knowing the specifics of the ground mount system they intend to use. Some are very expensive aluminium racks bolted to a concrete base and others are flimsy plastic tubs you fill with gravel.

Are they supplying the conduit that will go in the trench? Are they using 6mm2 DC cable so that the voltage drop is within SEAI specs?

work you need is to do dig a trench between the panels and house?

blocks; depending on how many you need will cost several 100 euro; and digging a long trench you’d be doing well to get it for 500-750 if you bring in someone with a digger and a person to operate it. More again if they need to be careful and hand dig parts of it around trees / fencing / etc…

Cant speak to technical merits of the equipment but..

I agree with http://davidhunt.ie/solar/

The value of the grant for this size array would be 2400. Using the rule of thumb of €1000 per kW of panels, €420 per kWh of battery, and say €600 for the Eddi, and €300 for the BER, that should be about €10086 for that system (after grant). But it's only a rule of thumb. Just don't go above €1300 per kW of panels and €550 per kWh battery (ex VAT), which would give you €12863 after grant. Your quote of €11885 is at the upper end of the recommended range. Get a few more quotes.The value of the grant for this size array would be 2400.

Hi all, looking into getting solar so still learning. Here is the first quote received.

10 panels - QCELLS 400w

Eddi diverter

BER rating included

App

34c for excess back to grid if I switch to SSE Airtricity

Cost 8200e after grant.

Was told this system would produce 3436kWh per year, our usage is 2200kWh. We are heating our hot water cylinder with gas so 10 panels should cover that too. However when I entered this quote into analyzer it seem like very expensive.

Seventy Plus · 04-11-2023 10:18pm

Two Inverters Required?

I would like to put panels on SE; SW; and NW. I was initially told that SW and NW could be on one string. Had a good quote for that.

Now I am been told that NW should be on a string to an additional inverter.

I am aware that NW would generate far less, but am not concerned about that.

Could I get away with One Inverter?

Mr Q · 05-11-2023 12:25am

https://www.boards.ie/discussion/comment/121326059#Comment_121326059

Yes it's possible to have 3 orientations on one inverter. But the strings would need to be the same size for the two that share an input I think.

deezell · 05-11-2023 6:46am

https://www.boards.ie/discussion/comment/121326059#Comment_121326059

Combining two panel arrays from different orientations onto one string input is best achieved by joining them in parallel. They will behave substantially as a single string of their individual equal sizes, i.e, if they are both 8 panels, they will produce the voltage of a single 8 panel string, but with a flatter spread of current output as the sun traverses from SW to NW, over a 90° span. As the sun moves to W, both will be equally illuminated, but with an angular reduction of cosine 45°, about 70% of their combined peak output. The most you can expect therefore is the output of an 8 panel SW string as the sun moves SW, to the output of 70% of a 16 panel array, about 10 panels but with the vertical angle of the setting sun further reducing this, and finishing with the NW panels only contributing as the sun sinks at NW in the summer. It will be well gone before it gets NW at this time of year.

Its would not be economical to invest in a seperate inverter for a NW oriented array. It would produce nothing for the greater part of the year, and little in the midsummer 3 months. It will barely even justify the panel cost if you add them in parallel to the SW array but ar least they will not limit the SW output.

If you add them in series, your entire output will be capped by the NW array performance, the string will be virtually useless unless optimisers are added, more cost and only modest increase over the SW array only.

I've not taken into account the vertical orientation of the panels, but could assume a 35° roof, which will of course alter the production profile of the NW panels marginallly as the declining sun moves SW.

deezell · 05-11-2023 9:15am

This sun calculator is a useful nerdy tool for determining percentage of maximum panel output at a time and date. It has a w/m² irradiation calculator (this is not panel output, but sun input/m², panel output is 18-20% of this multipled by panel area).

https://www.suncalc.org/#/53.2864,-8.1486,4/2023.08.05/18:50/1/3.

With the sun exactly west, about halfway to the autumn equinox on the 5th August, Sun is 21° above the horizon, NW facing panels on a 35° roof will have a cos 45° effective horizontal area and sin (35+21)° vertical, .7 by .82, about 57%. Irradiation of the sun at this place (midlands), date and time is about half the constant, so the panel output is about 28.5%. Thus 8 NW panels when they are beginning to produce will act like a little over 2, and will fall rapidly within an hour, as though the early August sun moves NW, it declines rapidly, so within 90 minutes panel effective area is 59%, but irradiation is down to 30%, .59 ×.3 is 18%, and the 8 panels are effectively 1.5 peak. This is just a few weeks either side if midsummer. Two hours after the sun is West, it's just above the horizon, and panel output is negligible. A few weeks after, you're done until May the following year. NW panels have virtually no output outside of May to mid August. I note that some panel production is possible from ambient daylight but have not calculated these, as the purpose of the exercise is to compare optimally oriented panels to sub optimal.
