A few months back, Martin Schachinger of pvXchange asked a question: Are bifacial modules taking over the market? Earlier, he had already noted the ongoing shift from full-cell to half-cut modules. And now, both trends seem to have foretold developments that are currently unfolding. While this cannot exactly be characterized as progress, because current developments are being driven by big Asian manufacturers, it certainly warrants a critical eye. Just a few months ago, the consensus was that the 500 W limit could only be cracked, if at all, by adding together both sides of a bifacial panel’s output. Now companies are close to introducing products to the market that have monofacial output of more than 500 W. How was this achieved so quickly?
