New 7.5 kW solar system + EV charger

[masterboy123]

Hi all,

How does this new solar system sound and cost is €6500? After SEAI grants.

5kW Sigenergy Hybrid Inverter.

7kW Sigenergy eV charger.

15 X TRINA 505W Bifacial Panels.

No battery.

Thanks

That looks like really good value, cost is 85.8 cent per watt and with that you are getting a hybrid inverter (so you can add batteries yourself later) and an eV charger.
For comparison when I was getting quotes last year the cost was between 1.14 and 2.50 euro per watt with no EV charger.

What is the name of the company that quoted you this please?

Is it okay if I look for fedback on a quote also, or is there some other thread for that?

I'm not as familiar with Battery pricing, so don't take my word for it here, but personally for that system, I would want to pay around 7,700 (i.e. 1 euro per watt solar and ~2k per 5KWh battery. But again, I haven't done a lot of pricing on batteries.

However what I would say is that you should try to max out the panels. Are you limited to 3.68 by roof size? If not, stick some more up there. They will likely throw them in for free if you ask nicely.

Thanks for this. Actually, this was a special price as I know the company owner. The owner told me that he wouldn't be giving this price to others.

Nearby similar houses have 8 contiguous panels (the fourth panel on top row is not visible here)





After sending up a drone to take photos, the guy said that to meet the regulations, he could do:

3 top row closest to roof ridge
2 next row
+ 1 + 1 + 1 separate, each of which requires an optimiser


The three optimisers and extra fire safety switch are increasing the quote.
