15 x Jinko Solar Co., Ltd. 460 Watt Panels (Jinko 460w or equivalent (JKM460N-48HL4M-DB))

1 x Sigen 5kW SP2 Hybrid Inverter (Sigen Hybrid 5.0 SP2) (Sigenergy)

1 x Sigen 9kWh Battery (SIG-STOR-BAT 10.0) (Sigenergy)

3 x Tigo Optimiser Single (TS4-A-O), 1 x BER Assessment,

€16,144 after grant- however 12 of those panels will be on a south facing steel veranda/pergola that is included in the price, the other 3 panels will be on the south facing roof. (2 of the roof panels on the west side of our dormer facing south and the other panel on the east side of the dormer facing south).

We had priced a veranda with a glass roof that we wanted to get installed and that came in at €15k approx so I think this way we are getting two birds with one stone.

Seems expensive without a battery.

I'm not sure, but I think it's just that they are modules like sig energy that can be stacked together, not necessarily that you are definitely getting a battery with it.

Aio konnect gear is specific to one installer, when they quoted me battery were extra (and expensive)

Hi all,

A recent quote:

14 x TW SOLAR 460 Watt Panels (TWMNH-48HE460)
1 x GW5K-EHA-G20 (GoodWe)
1 x GW8.3-BAT-D-G20 (GoodWe)
1 x BER Certificate, 1 x 5 Year Workmanship Warranty

Total System Price €11,400.00
SEAI Grant €1,800.00
Net System Cost €9,600.00

I haven't heard much about the Goodwe ESA system, I believe it's fairly new .

Any thoughts on Goodwe and on the quote received?

Thanks

I would appreciate thoughts on the attached quote for Goodwe ESA system including 8.3kw battery and including BER. It would cost an additional €500 for changeover switch.

Thanks

74 leapton bifacial all black panels.

3 no. S6 Hybrid inverters

17 total AC and DC isolators

5 din rail meters

4 fireman switches

cable, solar mounting rails

Making the mounting frames myself

Just to buy cable back to house

Total €12100 have another old 5kW inverter there to go with it

I would highly recommend getting them the battery, it gives you much more flexibility about what you do with the power the system produces. If your parents tend to use 10 kWh or less a day (excluding car charging which can be done on EV rate from the grid) you could easily charge the battery on a cheap night rate (or EV rate) for less than €1.00 and run the house for the day on that battery and sell most of the solar to easily bring them into €0 bills territory.

If they live rural and ever suffer from power cuts it might also be worth considering a Manual Changeover Switch which means the solar will still work if the grid ever goes down to power house and charge battery (Rough extra cost is about €1000 to add this).

Without this the solar system will no longer work if there is an outage.

Has anyone experience of complaining to SEAI about a contractor who has not finished the work?
Note To Mods if there is a problem posting this here, please advise options

I got a reasonable quote 6k then I said my budget was 5.5k

and the solar company lowered quite to 5.6k.

With demand so high why would they agree to lower quote?

Hi all, i got quoted for, the following system - i actually paid the deposit with them, so have to go with them, Its a North Monaghan company - not the one that avertises like hell on TV:

• 9.2 kWp system
• 20 panel - JA Solar 460w N type - 30 year warranty (2 free)
• 5kw Solis Hybrid Inverter
• 10.24kw Dyness Powerbox
• New BER required for Grant
• All electrical work includes the following:
  • Projoy Shunt Switch
  • AC and DC Cabling and Isolators
  • RCBO Switch
  • Full Label Kit to identify all components
  • Testing and Commissioning
  • Renusol Mounting Brackets and Rails
  • PV Check Meter
  • Cloud Monitoring App

Cost after grant - 9500 euros.

Its a local company.

Ive an A2 rated large house. Just competed 2020. south facing back roof, south - east side roof.

electrical bill approx 2100 euro a year, energy usage 7500 kws a year average.

See my quote above, €10,800 with no grant and a larger battery.

Did the numbers with my parents over the weekend, ROI was roughly similar with/without battery. Longer term, battery makes sense. Found Gary Does Solar quite good but I was able to make my own informed assumptions based on their usage patterns.

I'd probably disagree with you on that.
