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

Not as straight forward as that. What about nighttime or when the sun don't shine or long periods over winter?. Will you be in the house to use whatever you generate?. Do you use electric showers, washers, dryers, heat pump, electric heating etc. All must be considered for each individual house

I WFH 4 days/wk. Use gas for heating and hot water. It looks like our annual energy use was approx 4,000kwh last year.

Understood about the “sun don’t shine” comment but over the course of a year, are the energy generation calcs fairly accurate? The feed in tarrif for SSE is 21c/kwh so at the calculated annual energy generated value of approx 4600kwh, this works out at €80/mth (960/annum) so essentially paying for the loan. That’s if 100% of the energy generated goes back to the grid so surely I would end up somewhere in between….

4600 a little optimistic, unless you're in the sunny South East. https://solarshare.ie/news/are-solar-panels-worth-it-in-ireland-2/

I'd say 950 Kwh/Kwp might be more realistic, but if it displaces say one third at home use, 31c and two thirds at FIT, 21c, you're still looking at €80+ per month*. Unknown are possible maintenance costs over ten years, and a big drop in FIT if energy prices drop. Looks like it would pay alright.

* 950×4.3=4085kwh/annum. 4085×⅓×31c + 4085x⅔×21c = €994/annum, €83 per month.

In a nutshell (especially now with the removal of VAT there recently) installing solar is is one of the more fiscally beneficial things you can do to your house. Typical pay periods for a non-battery installation is about 6-7 years, with an extra year or two if you have a battery. Some could be as low as 5 years, and some 10years....It's complicated to go into it over a quick IM here as it depends on the size of the installation, your consumption, the quote you paid for the system, the rates your on with your supplier, etc.

Larger systems "tend" to have a faster payback period - but a decent rule of thumb would be in about the 6-7 year period. After that, your "quids in" and can enjoy lower bills for years. If you have the space - go bigger than 4.3kwp. At some stage in the future you probably will have an electric car and you will want the extra juice. Think ahead.

Cheers man. That’s the max we can go for the available roof space and I think the output will essentially match our requirement for the year but the goal will be to get an EV and if a manufacturer would have reverse charging on the batteries, the ROI will be even better

Any thoughts on this - it includes removing 3 thermal panels that are built into the roof and reroofing the area they are in before installing 12 panels. Also Includes a Zappi charger

Net of grants it's €11k

Also will there be much gain from mounting bi-facial panels on a roof?

I thought they were more suited to ground mounted systems where the rear face could capture some light unless I'm missing something in your setup?

Hi all,

Hoping to get 4-5kWp in the New Year, do installers typically charge much to integrate existing panels, any issues with doing so? House has 1.2kWp but I'm not looking to move them as new panels will be on the other side of the house so hopefully a simple installation?

No plans for a battery as I have an EV so I suppose it's just a matter of getting a few quotes?

Going to start reading through this thread.

At the last hour I have a quote of €7,600 before Grant

15 x 435w jinko panels 

1 x solis 5kw hybrid inverter 

10 x tigo optimisers

Vander valk mounting brackets 

BER cert

All grant paperwork 

Yes I can get Grant. It took the whole day between two firms as I want to apply for grant in morning.

I was also working on behalf of a friend.

As Munster was mentioned it is Ulster

Just came back to report on my own situation. Last week the best quote I had was 4,700-5,000 net of grant for either 7 or 8 panels. 7 would be a 3.05kwp system. Works out at 1,566 per kwo installed which was a bit above the target of paying 1,200 per kwp installed. As I have had 10+ quotes with some as high as 8k-9k across an on-off search for months I was nearly going to go with that quote on Monday. Id resigned myself to the fact that as mine is such a small system that I was never going to hit the 1,200kwp benchmark Id hoped for.

But despite the company ringing on Monday after a site visit the previous week and putting a bit of pressure on with the grant reducing and paperwork needing to be in before Wednesday I decided to hold off a couple of days. Then on Wednesday out of nowhere a final quote came in from a different company at only 3,700 net of grant or 1,233 per kwp installed. Spoke with them on the phone and so far all seems good so I applied for and received grant approval from the SEAI yesterday thus avoiding the 300 grant reduction coming on Jan 1st. To finally hit that 1,200/kwp benchmark after so many months of frustration was almost overwhelming. Im over the moon with it as it will give me an even faster payback period than the quote of 4,700. The grant approval is valid for 8 months so once Ive some bills out of the way in January I'll go ahead with the install in late Feb or early March just in time for the days getting longer and the sun much higher.

Thanks to all on this thread who helped out their with invaluable advice and experience. Literally couldnt have done it without ye.

Actually, I don't think you are being entirely unreasonable. You had a survey, and got a quote based on that professional survey, which would have included a risk assessment for the installation.

You then agreed a price and paid a deposit, not only are you locked in, but so are they.

To my mind, and omission is on their part, and they should have identified the risk at the time of survey, that is not your fault, the blame is entirely with them.

They now expect remedial works to be completed which will just allow them to do the job they were paid to do in the first place, those remedial works having absolutely no benefit to you, and yet you have to pay for part of it ?

There is also the point,.that their initial assessment included the cost of hiring a mewp, which they have now said they won't or cannot use, and have asked you to put in the additional cost, yet they also will save by not having the mewp hire costs.

There is in fact, no fault on your side of the problem, it is entirely theirs. That's not to say dig your heels in and insist on anything, its just to say, come to a reasonable agreement, you should not have to pay beyond what was quoted, and you should be compensated in some way for the delay in install.

Be firm, be reasonable and be fair, keep in mind the origin nal.afreement, and the losses that you are now expected to take on.

Keep in mind the savings they will make by not having to hire a mewp also.

And, last thing to check, was your quote before or after the point where solar installs became vat free?

Well done! It goes to show there is still good value to be had. Best of luck with it.

On Wednesday / Thursday
