Domestic Solar PV Quotes 2022 - No PM requests - See Mod note post #1

I'm having the same experience, also long lead times, guess they're busy.

The ROI depends on a lot of factors. In general terms the size of the system, and the % self-consumption that your doing. Smaller systems (sub 5Kwp and ~2-3Kwhr battery) tend to be 12-14years in my experience. Larger installations 7-8Kwp and 8Kwhr closer to 10 years, some even sub 10 years.

My own (5.3Kwp with 8.2Kwhr) is on track for about 7 years ROI. I got a good price last summer (€8500) albeit back then we also had the grant for the battery (€600) and it was before the madness started with battery shortages, panel shortages, Ukrainian crysis, energy crisis etc..... which has driven up the installation prices a lot. I also self-consume virtually everything I produce at day rate too so I'm a little unusual.

Still I've seen the odd quote come through recently which gives some hope that there's still value out there. You might not get sub 10 years, but I think you can get there abouts.

Small systems deffo cost more and takes installer longer. We paid 1.6k per kwh of panels. No battery bought. And I'm happy with that. Got 5.1kwh installed. Our panels are up and just waiting on their sparks to make them all live. They installed on 4 small roofs to max all we could get (it's a very small house). So they took spare panels on the day to get as much as they could up which I asked for. Smallest roof only fits 3 panels (its that small), 2 roofs fit 4 and one fits 5. And he gave us a 2nd inverter FOC due to needing 4 roofs using 3 orientarions (they didn't think the roof was that small until install day). We've now panels on East, South and West to should get a good spread all day.

So they had way more install work to do than if they just did a large South facing roof. So...every gaff will be different. Every design is likely different with each installer....=> every price will be different.

But knowing the 1.2k per kwh price as a 'rule of thumb' really helped me see what to aim for.

And I'm really happy with our installer. I wanted their support and knowing they are a reputable outfit. Don't get me wrong - price matters a lot but it's not 100% of the decision for us.

Lastly huge thanks to everyone for their time on this forum. Deffo has taken me from 'not knowing what I didn't know' to 'knowing what I don't know' - still most of it :) And for giving me the confidence to pick one installer over the other quotes and challenging part of their designs

No, no its not. Keep on hunting.

€1.2k per 1kWp

Add €50 per optimizer

Still there, they were up in Donegal last week doing installs and a bit of work for @DrPhilG as well afaik. I reckon they are just too busy at the minute.

Hey folks, got the below quote but think it’s probably a little high. Would I be right in saying it’s probably about €3k north of what I should expect?

16 340W panels

5kW battery

No EDDI

€14,000

System size: 4 KWp - 10 panels

Solis Inverter

BER for grant icluded

Wireless monitoring

East/West split

After grand: €6300

Any good?

Installer plans to come this Monday, so fingers crossed I might generate a bit of electricity before the summer ends, expecting to export a good bit of it during the peak months but interested to see how it works out in any case

Got an out of office for this week. Probably of for the 12th holiday

We have two EVs and we’re considering getting solar PV panels. We already have thermo water panels (whatever they’re called - new build) so we won’t need a hot water diverter.

I checked our bills and our average usage is 20hwh per day, how many kwhs of panels do we need? 6 seems too low for our needs?!

A house in my estate has recently installed panels and they've managed to fit 12 panels on the westerly roof. They also have them on the east side, not sure how many there but I think 6 panels. Is it possible to get 20kwh of power per day from panels? Sorry, still learning about them

With 2 EVs you need to fill your roof space. You could easily cover 20kwh and then some in the good months.

Yep - don't worry. They are on holidays & due back next Monday July 18th etc.. I have been contacted by the owner this week so I know this for sure etc.. I'm in the midst of an install with them.

Hoping my sums are right, others with more experience can correct me if not:

10x370=3.7kWp

€1.2k x 3.7=€4440

Add another €550 for EDDI = €4990

So should be around €5k after grant in theory
