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

Thank you,

Just to be clear, the Boards guide is a price that has already had the €2400 grant subtracted?

The quotes I listed from a contractor above have the grant (possible €2400) subtracted.

So for a 'like for like' comparison with the Boards guide:

• Or €1.2k per 1kwp + €550 = €8350 is the price I compare to the contractor's quote when the contractor is subtracting the grant.
• €1.2k per 1kwp + €550 = €8350 + Grant = €10,750 is the price I would compare to the overall quote from contractor.

For example, the first figure I list is €8950 which I should compare to the €8350 as a rough guide.

In which case the contractor is roughly priced 'right'.

If this is the right interpretation...happy days :)

Thanks again,

Peter

Yeah, one of the better quotes that we've seen lately. Remember the formula is only a guidline. It tends to be easier to match the formula for larger systems and more difficult for smaller ones.

If your happy with the supplier, I think you could be onto a winner there.

I know which installer you mean, he is having trouble like all installers finding stock of just about everything lately. You could try some EU sellers but I would imagine it's the same story with demand out doing supply. Keep looking though you might get lucky.

If your installer is NI based and you find what you are looking for, get them sent there to avoid duties. Just a thought.

I got a quote for a similar system this week:

4.1kw (10 panels) + Solis hybrid inverter + Eddi+ 5.1kw battery. 9k after grant.

The quotes have the grant amount as the same (€2,400) for both.

Apologies for going off topic a little...

I wonder are your solar tubes working as they should. We are in a similar setup and have thermal solar panels for hot water. On front of the hot water tank is an air to water heater type unit which works when the heat is not available from the tubes. As we are not long here I assumed the unit wasn't doing much but now I'm not so sure. It seems to kick in more often than I thought. We also have a ground source heat pump and are racking up 18k units a year. The house is not brilliantly insulated so I'm sure that's part of the problem but now I'm wondering if the solar tubes are not as effective as they should be.

In the absence of sun, how are you getting hot water? Perhaps this might be the issue or part of it.

Anyone know if I need to have a grant offer before paying a deposit? I'm ready to pull the trigger!

Pick your installer then apply for the grant so it is in place before you pay a deposit, it gets approved in a few days so not much of a wait to be safe. Make sure you intend going with the installer you put on the grant form, I'm not sure if it's much hassle to change installer information after you submit.

Haven’t been yet. Just gotten the quotes for now. Have reverted with a couple of questions but will prob ask tomorrow what the timelines would be.

Hi, I’ve turned the heatpump (Daiken 14kw 11 years old) water storage off for the last week or so to check the solar thermal tubes are working. They’re heating a 300litre tank to 60 degrees top and bottom, so working but conditions are perfect.

The heat pump generally heats hot water at night heating the top of the tank to 70 degrees but as I haven’t been monitoring it it difficult to say the units required to take a cold ish tank up to 70. Once the weather changes I’ll check.

I’m waiting on an eco eye 600 to be delivered (stock issues) but have worked out my daily average usage with us in the house for the past week as 9 day time units and 4 night time. The reason for the higher day time is most likely some large pumps we have for water and just general living (washing machine etc running at night).

Regardless the Pv install would seem to make a lot of sense for people in our situation.

Pretty much decided on a 7.4kw jinko panel system with 6kw inverter and 10kw dyness batteries no Eddie (yet anyway). I’ve had a good few quotes now from some of the popular companies on here and they are all coming in around approximately the same with similar generation predictions of 5k to 5.6k annually. This makes a very big dent in our bill at 0.3c a kw and prices going up. Payback should be about €1600 a year we hope without factoring a winter battery benefit.

hope I’m right 😅.

Grant approval all sorted and deposit just paid.

6.9kwp JA system

Solis 6kw hybrid invertor with wifi dongle

5kwh Pure Drive battery

Eddie and BER included along with roof kit, check meter, isolators etc.

€11,500 after grant. Okay I think?

70C - is that not a bit high for a heat pump? Could that be part of the problem with your heavy usage? Most heat pumps will do 55C maybe 60C and then any higher temperature over that (unless it's a split phase system) is normally heated by conductive methods, i.e. an electric heating element. However, while I'm pretty clued in on the solar/electric side of things - I have to profess my knowledge of heat pumps is poor.

If I was you, I'd lower the hot water target in the heat pump down to 55C (or 60C at a push). 55C is still plenty warm for a shower as in you'd find it uncomfortable warm if you didn't mix cold water in with it. Take a note of your usage for a week and average it out

I think your right not going for an Eddi - least not for now. But yeah like championc mentioned, don't forget that you won't reap all that at day rates, although I'd probably ballpark it a little higher. maybe €1100-1200

I assume you have a hybrid inverter mate? With the FIT being reasonably generous, I'd probably say 2.5Kwhr battery max. You have a grant so your economics could make it work, but you'll probably struggle to fill a larger one from solar with 2.5Kwp. Sure you could go for a 5Kwhr, and use it as you mentioned a way to get the off peak rates for daytime/peak usage, but i guess that would depend on your consumption profile more than anything.
