Cell technology: why N-type instead of PERC
Half-cut N-type TOPCon cells (108 half-cell) replaced P-type PERC precisely because they remove the older technology's main weakness — rapid degradation in the first weeks of operation caused by boron-oxygen defects. Here the manufacturer states first-year degradation of no more than 1%, followed by roughly 0.4% per year, with a 30-year performance warranty confirming at least 83.1% of nameplate output retained. The half-cut layout also reduces internal current losses and improves resistance to microcracking during transport and installation.
Which systems it fits best
Thanks to its moderate, "mid-range" power rating, the module works well when combined across roofs with mixed slope orientation — some rows facing south, others east or west — without a sharp power mismatch between strings. That matters for houses with an irregular roof shape, dormer windows, or existing obstructions, where a single orientation across the whole surface simply is not possible.
Real output, not just datasheet numbers
Glass-glass construction and IP68 protection
Rear-side generation up to 80%
The bifacial construction adds generation from the rear side — the manufacturer states a gain of up to 80% ±10% above nameplate under favorable reflection from the surface beneath the array. The actual gain in practice depends on roof color, material and mounting angle, but the fact that the back side is active at all means extra kilowatt-hours essentially "for free," with no added cost to the panel itself.
Black Frame design
The fully black finish — frame, backsheet, cells — produces a uniform dark surface that looks good on slopes facing the street or yard and requires no color matching with the roofing material.
Installation crews often note that mid-power modules in a given series tend to become the "invisible standard" of a lineup — rarely discussed individually, yet they come back with fewer warranty claims and consistently hit their projected output figures across the full warranty term.
