Unsurprisingly the Aiko panels above are unavailable. I've been offered the Longi ones & I wondered if any opinions.

We are looking at 10-11 panels as limited space on a flat roof ie aesthetics immaterial. Any thoughts pjease?

Sound great on paper, but only released Sept 25 to uk market as far as I can see.

Aesthetics immaterial, I'm just looking at maximising potential energy from my limited roof space.

Any thoughts on 3rd gen 480W Aiko vs 2nd gen 515W Aiko?

I have quotes for both but have been told that, with battery life warrantied for 10 years, Goodwe have better ELO efficiency than Sigenergy.
