Bletchley 😏

Have you seen your post? It looks like something from a code machine. Bletchley was where they cracked the German code.

It can depend. if 380W panels are much smaller than 420 (or other 400+) panels then for your roof shape installing more 380w panels might work out better than less large ones.
For example if your roof absolute max could only fit 10 of any of the 400+ size panels to comply with SEAI edge distances etc. But at the same time you could fit 14 or 16 of 380 panels (and inverter allowed 16 of them) then I'd take the 380W panels.

14 x 380 = 5320W or 16 x 380 = 6080W vs 10 x 435 = 4350W

Now in your case 14 x 425W =5950W. But we have had people promised we can fit X panels on your roof only to find on install day thats not the case! (this is obviously ignored prices of each!)

Ask him if trading under a different name, I know my installation company went by a different name on the SEAI website.

BTW using 380w panels these days would also raise a concern for me, they are obviously years old stock.

All, firstly I want to say how useful and informative Boards is and that’s down to you guys and the depth of your combined knowledge and experience.

In the last 3 or 4 weeks I've read nearly everything on Boards in anyway related to solar pv.

This has led me to booking one of 3 companies that did site visits, it was tough making a decision as the final two were very close in both price and presentation.

We are going for:

12 × 435W LONGi Solar Hi-MO 6 Scientists, 8 on front true south facing roof (max we can fit) and 4 on the north facing roof. (may increase that on day of install to 8 based on my readings of the north facing panels piece here on Boards).

1 × Solis S6-EH1P5K-L-EU 5000W Hybrid inverter, any comments on the series 6 compared to the series 5?

1 × WeCo 5K3-LV-5.2 Battery

Cost with grant <€8000 (for the 12 panels, additional on the day €180 each)

Now I’ve asked the company a whole heap of questions, most of which they have answered ok.

What I was looking for was advice regarding switching from 24hr to TOU electric contract.

We have smart meter on 24hr contract with Electric Ireland due for renewal next month, I've already negotiated 22% discount from the 18% they were offering existing customers, but was wondering should I consider moving to TOU.

Electric Ireland's smart deals don’t look that great and I don't like the big difference between their day and peak rates. (I know in theory that we should be able to smooth the peaks with the PV/battery) but the lower the difference the happier I'd be.

Energia have what looks the best (dual fuel smart plan where the day and peak rate difference is small) so I am looking to switch to them.

I’m assuming you can’t constantly charge and discharge during the night where you are buying electric at €0.16 and selling at €0.24, so would I be better with one of the tariffs that have the ultra low EV rates for just a few hours.

I assume a 5Kw battery will easily charge to full in three hours (providing the house load is not massive)?

Thanks in advance

After what happened to Solarshare and all the people who basically had their deposits stolen, there is no way I would pay a company that kind of deposit, its outrageous.

You dont mention pre or post grant or no grant?

Ok, the quote seems good. The price is in the ballpark that I was quoted for a similar system and I thought it was very competitive at the time.

If your on the facebook group with 56k members, you can do a search or ask about the particular company over there. Its an excellent source of info, just be very wary of that deposit. 🤨

Can I get the name of the company the quoted you please?

Another quote from a different provider today

Quote 1

17 x 435 watt panels (Trina Solar)

Inverter : 5kw Huawei 1XSun2000-5KTL

No battery

No EDDI

Total pre-grant : 9350

Total after grant : 7250

Quote 2

17 x 435 watt panels (Trina Solar)

Inverter : 5kw Huawei 1XSun2000-5KTL

Battery : 5kw Huawei 1xLuna2000-5-S0

No EDDI

Total pre-grant : 12250

Total after grant : 10150

Provider is recommending the quote without the battery. His logic is that I will return enough to the grid during the summer, that it will offset my winter bills, meaning my annual electricity bills would net close to zero.
