Low costs for TOPCon photo voltaic panels put stress on PERC – pv journal USA

-


In May 2024, high-efficiency panels, largely glass-glass modules with tunnel oxide passivated contact (TOPCon) cells start to converge in value with mainstream choices, writes Martin Schachinger, in pvXchange. Production volumes for these negatively-doped, “n-type” cells and modules have been ramped up in China whereas more and more restrictive customs circumstances within the United States could have an effect. For the European market, the fixed drop in costs for the newest module expertise would counsel that demand would proceed to rise if not for a number of disruptive components.

In Europe, there are nonetheless extra shares of modules produced in 2023, or earlier with distributors and installers themselves. If they’ve small dimensions which are usually used for roof techniques in Germany, they don’t promote nicely due to the low output energy sorts. Building house owners usually need to see excessive wattage and the newest expertise put in of their techniques, making it harder to promote present stock.

Despite the supposed decline in module manufacturing, and European import volumes, it seems that extra Asian panels nonetheless attain the European market than present demand.

The stress to promote ought to, due to this fact, not exceed widespread sense and tempt suppliers to take numerous dangers.

Some suppliers additionally attempt to flip to on-line markets the place they hope to promote shortly to worldwide prospects with out the prices of gross sales and advertising and marketing.

Misunderstandings can come up in enterprise transactions, particularly throughout nationwide borders and the platform operator just isn’t all the time out there to supply help and recommendation. The effort concerned in an internet transaction can simply be higher than shopping for or promoting inside a longtime enterprise relationship. Everything may go easily however that does not imply it’ll.
