The Short Version
The workhorse, and still the right answer on most roofs.
A mature, widely understood and inexpensive module built on half-cut mono cells. Where budget rather than roof area is the constraint — which is most projects — it remains the sensible specification, and the series runs from 250 W right up to 585 W.
Positive power tolerance
Sorted to 0 to +4.99 Wp, so a module never ships under its nameplate rating.
Multi-busbar cells
Better light trapping and current collection, and lower resistive loss than a full-cell layout.
Anti-PID performance guarantee
Specified for humid and coastal sites where potential-induced degradation bites hardest.
Reduced hot-spot loss
Individual bypass diodes in an IP68 split junction box.
High mechanical load rating
5400 Pa snow and 2400 Pa wind.
Strong low-light response
Useful output earlier and later in the day, and through overcast conditions.
Applications
Where this range is specified
Residential rooftop
250–360 W for compact and shaded roofs.
Commercial rooftop
500–585 W where area is not the constraint.
Industrial captive
Cost-led builds with generous roof area.
Institutional
Budget-scrutinised public and campus projects.

Should I choose this or TOPCon?
If roof area is the constraint, TOPCon — more kW in the same footprint, and a bifacial rear-side gain on top. If budget is the constraint and area is not, the mono-facial series. We will quote both against your layout.
What ratings are actually available?
Twenty-one, from 250 W to 585 W, on 72, 96, 108, 120, 132, 144 and 156 cell layouts. The smaller cell counts suit compact roofs; the 144-cell modules at 2278 × 1134 mm are the commercial workhorse.
What is the power tolerance?
Positive only — 0 to +4.99 Wp. A 540 W module will flash at 540 W or better, never below.
What is the warranty?
10 years product and 25 years linear performance.
