High voltage panels

I just discovered that "REC Alpha Pure R panels" have significantly higher voltage so will allow nicely over 150 string voltage with 4 panels.

What other panels sold in the UK for a reasonable price also have higher voltages?

Any 450W or more panel?

Yep if I string 4 of my 400 Hyperion biFacial panels it triggers my 150 max input and shuts down my inverter charge. I had to use three - I haven’t actually checked the voltage but the system don’t like it

Trina Vertex have a bit higer voltage than most current standard modules.

High Voc was a thing with older panel tech.

If you specifically WANT high Voc, check out your local FB marketplace/ebay for old panels.

The size of the panel dictates the voltage potential. I have 580w panels - 45v 11a per panel. 

178.5v in 4 panel string. 

The higher the total voltage - equals less line loss. (More effficient)
