When a project brief comes in, the instinct is to compare brands – this manufacturer against that one, warranty against warranty. But before brand ever enters the conversation, there’s a more basic decision that shapes everything downstream: which wafer format the module is built on.
Hanu Solar builds on both. nexyra runs on the M10R platform; zorex runs on G12R. Same factory, same N-type cell technology, same certification stack – the difference is entirely in the wafer, and it changes more about a project than most spec sheets let on.
M10 and G12 are industry-standard wafer size classes, not brand names. M10 wafers measure 182mm across; G12 wafers measure 210mm. A larger wafer carries more current per cell, which means a module can reach a given wattage with fewer, larger cells – or push higher total wattage using the same cell count as a smaller-format module.
That single dimension change ripples into module size, weight per watt, and how many panels a given roof or field can actually hold.
| Spec | nexyra · M10R | zorex · G12R |
|---|---|---|
| Model | HS10-T144-GF | HS10-T132-GF |
| Cell format | M10 (182mm) | G12 (210mm) |
| Cell count | 144, half-cut | 132, half-cut |
| Power output | 565 – 595 Wp | 600 – 620 Wp |
| Cell technology | N-type mono | N-type mono |
| Warranty | 12 / 30 yr | 12 / 30 yr |
M10R modules – a higher cell count at a more moderate per-panel wattage – suit projects where module size and handling weight matter as much as total output: residential and smaller commercial rooftops, tighter access sites, installs with fewer hands on the roof at once.
G12R modules pack more wattage into fewer, larger cells, so each panel carries more power. That favours larger commercial and ground-mount projects, where fewer, higher-output modules mean fewer mounting points and less wiring per kilowatt installed – provided the site can handle the larger panel dimensions and the crew can handle the added weight per unit.
Choosing between them isn’t a quality decision – it’s a fit decision. The right question is what your site, crew, and racking system are actually set up to handle.
