Domestic Solar PV Quotes 2024 - No PM requests - See Mod note post #1

How come such a small system? That's only about 5 panels, have you no more roof space or ground space to fit more? It is very expensive so I wouldn't entertain it at that price.

Total: €13,900.00

Guys, I think I am reasonably knowledgeable to comment, firstly hand tool http://davidhunt.ie/solar/ to give you an idea whether you are being quoted under or over the odds.

In our case 16 panels (roof mounted) 2x WECO batteries and 5K Solis inverter with grant €10,700, local enough firm and very proffesional from start to finish, system is up and live nearly 2 weeks and can only say should have got it in sooner.

Thanks

Celbridge, so we switched provider (paid the early exit fee), as you can see on the Enegria app we will soon have that covered and much much more, long may the sun shine.

Thanks

That looks like a good quote for a ground mount system. You consume a good amount of electricity, I would try and maximize the panels on that Solis inverter which is probably at least 2 more panels.

Thank you

I've decided to bite the bullet and get my long sought-after solar PV. Have the guys calling next week to give me a quote. I have a weird roof layout, the south facing part is used up with two pitched roofs running into it. So the usable space is really an East / West configuration. Space at the gutter level is 5m X 4.5m. There is a small bit of extra space where the roofs meet at the angle that looks like you could squeeze in one or two more on either side. I guess around 12-16 panels is what I'm looking at?

I have a few questions that others might have had similar choices when getting theirs set up and would be interested in opinions around hwo it worked out.

I have Solar tubes for hot water. Should I rip them out and get PV to do the hot water? The tubes are 15 years old. On their day (very sunny summer) they work well and i get well over 40 sometimes 50 degree water. But since I bird pulled the temp probe out of the tubes on the roof less so 😀. But when the lads are up there I get them to put it back in. So I'm leaning towards leaving them.

Battery: What is the latest consensus? Is a small 5kw worth adding now with the FIT. I do work from home and have an EV here. So day time use is higher than an empty house. And I could just plug in the car on a sunny day and not bother with a battery? Or would a battery still be a good idea, especially with an East/west set-up. It would get a nice lot of sun in the morning when the house is on very low power use and it could top up the battery before we even wake up so might help there.

Any advice is appreciated 😀

If you buy a ground mounted system and do the panel installation yourself is there a list somewhere of qualified electricians who would do the electrical work ?

that’s is an amazing quote . What part of the country are you in . Would you pm the company if you are in the west ?

Who is the with? I'm getting quotes of 5800 just for 10 panels and 4.3kwp system!

How much does BER usually increase? I'm b3 and thinking to get 4 kwp

Guys, quick question regarding inverter capacity.

So I understand from the installers that the max inverter you can install on domestic system is 5KwH and hence the max you can export is same and that anything over that is not actually generated (providing house and battery are satisfied)?

What is to stop you (once SEAI have paid the grant) swapping from 5 to say 6 or larger inverter, could ESBN "detect" that you were pushing 5KwH plus back onto the grid or would your supplier have anyway of telling by the amount of FIT?

Or is it just not worth the cost of doing the swap for the small gain in export?

Thanks

You've sort of answered your own question there. Yes, you will get more generated every year with a 6kw over a 5kw (assuming you have the excess panels sizes and are "clipping")…..but people completely overestimate the effects of clipping have on their production. In reality, even on the sunny blue skies all day long, your probably only clipping for a few hours. Unlikely to see any clipping in Oct-Feb. Maybe you get 5-10% more….maybe.

Is it worth the cost effort….. probably not. As deezell mentions above some inverters can take more than 5kw and send the excess to a battery, but not all. My own one (GivEnergy) just handles about 5.6kw and that's it. I might get an odd spike to 6.5kw for a few seconds, but it pulls back to 5.6kw quick enough.

can the solis 5KW hybrid handle clipping? if I had 10KW of battery would it be able to feed house and also filling batteries @ the same time ?, then once batteries are full top up immersion with Eddi?

im looking at putting in a 7.8kw system south facing
