Did we make the right choice in our Solar PV?

Sounds like you're all set so, your sparks nephew could probably do all the required AC work and NC6 paperwork if you want to get FIT. It is fairly simple and most inverter manuals are very good at showing you how to connect up correctly.

My Newphew is going to install the 32A RCBO and cable + Cat 6 - Honesly the Sparks who comes on site will have a piss easy job as most of the hard work is already being done :( if I knew a roofer I would ask them to install the panels are the quotes I'm getting are just silly, the price of the gear is actually very affordable the installers are just taking the piss if you ask me.

They can tie to Grid he has a sparks that does the NC6 Form, I'm waiting for a quote from him, my nephew is actually doing all the AC work anyway as I'm getting an office build and he has to pull a 10mm SWA cable from the board so its simple for him to add 1 extra cable and a Cat6, its just a 6mm twin and earth 32A RCBO and a Cat6 for the CT clamp, I mean the hard part is the roofing of the panels but the Electrical should be piss easy.

Hi all,

sorry for all the spam, just got a quite from ********** for 10 JA Panels 415W / 5kWh Solis inverter for 6.5k seems like the best price so far!! I would prefer the 430/435W panels we can fit 14 panels on our roof but my budget right now might not strench that far.

Modnote, can't name suppliers.

Would he sell batteries and add them on after solar is installed?

Ya I asked him the same thing, its fairly simple but I'm sure he will for a fee, as he would need to travel and connect it up

Don't lay a CAT6, they are cheap as chips, lay at least 3 of them

Heatpumps are expensive in the winter alright but more that they are expensive v the summer, overall compared to someone who is paying for electricity and gas/oil or other your heating costs should be lower, that said having solar is great, although highest production is at a time when your HP consumption is lowest!

Ive reached out to him basically your looking at E1500 per 5KWH, add E250 for installation

So 15KWH = E4750. (+250 for a cabinet if required)

Im currently looking at that price for 10kwh with regular solar installer

Thoughts? Any risks to operating battery install, I guess warranty is with Pylontech.

Model US5000

The US5000 is perfectly safe little to no fire hazard with a LiFePO4 battery, I'm looking to do the same myself, I'm thinking of getting the panels installed and getting him to install the batterys after the fact as he has very little installs done, and the last thing I want in a new house is a roofing issue :( so peace of mind I might get a well known installer and get the batt from him.

He also does a 15Kwh battery its very large but that might be more cost effective as its 2.3k

If you can stretch to the extra 4 panels it will be money well spent to max out your roof space. That would be 5.81kW and the 5kW Solis is ideally suited to it. Any clipping will be minimal.

Also, I see he is selling 2nd hand 450w Longi for €90 each if that's a possible option for you. Personally I'd have zero issues using them as long as you don't mind that they're not black. 14 of them would give a very nice 6.3kW array.

Do you know a good roofer in Cork, as if I can get the panels done myself and get the electrics by an installer I would, as the cost of install is just insane considering you can buy Jinko Panels for under €160 each brand new including VAT

Good stuff, keep me posted as it sounds like we could go same route.

Any idea of the model of the 15kwh battery?, his quote to was just 3 X 5kwh.

Mine would be a relatively easy install in plant room downstairs. no dragging them up to attic.

Should have my panels installed in 4 weeks

Hi mate it seems to be a DIY batt, but LifePO4 cells so risk of fire and stuff is beyond low compated to Litium batts - https://www.donedeal.ie/tools-for-sale/brand-new-14-5kwh-lifepo4-battery-solis-compatable/35440047 - 2800 for 14.5kWh

Good value but don't think id go down that route..

Why not ask that chap for a price for panel/roof install only or an 'all in' install? Any REC can do the NC6 so your sparks relation can do all the AC stuff.

Just a heads up on the RCBO, use the manufacture recommended one as using a 'normal' 30mA one will probably lead to nuisance tripping. Normally a 100mA is recommended on Solar but check when you finalise the inverter model.

Just1ce4all

Has anyone any experience witn SAJ? as I'm looking at getting that inverter over the Solis simply because of the 5.5kWh option as Solis does not have this :(
