630W N-Type TOPCon Bifacial Solar Panel
The DT630-33V-MHDRz is a 630W monocrystalline N-type solar module in the 610–630W series. The series uses TOPCon cells, a 132 half-cell layout and dual-glass bifacial construction. The format suits projects where string current, available space and mounting conditions are checked during system design.
The 630W rating is measured at standard test conditions (STC). Actual output varies with sunlight, module temperature, shading and rear-side irradiance.

TOPCon Cells, Half-Cell Layout and Bifacial Performance
N-Type TOPCon Cell Technology
The N-type TOPCon design should be evaluated using this model's temperature coefficients, degradation data and low-irradiance performance.
Dual-Glass Bifacial Collection
The rear face can receive reflected and diffuse light. Any additional yield depends on ground reflectance (albedo), mounting height, row spacing, obstruction, tracker or fixed-tilt geometry and site conditions.
Follow the module installation guide when planning lifting, handling and clamping.
Inverter and String Compatibility Checklist
For the 630W model, the published 15.36A Imp and 16.20A Isc at STC are particularly important when evaluating inverter MPPT input limits. Bifacial operation can raise module current further; the published BNPI Isc is 17.82A.
- Minimum design temperature and maximum cell temperature
- Inverter maximum DC voltage and MPPT operating range
- Maximum current and short-circuit current allowed per MPPT
- Selected string count, module count and orientation
- Rear-side irradiance assumptions for a bifacial array
- Mounting system, clamp zones and structural load report
- Connector compatibility, cable lengths and earthing design
- Destination-market documentation and electrical rules
Series-string voltage increases in cold conditions; the manufacturer temperature coefficient is required for final string sizing. Check the applicable solar inverter range and solar mounting options with the project design.
630W Module Applications and Installation Fit
Ground-Mounted Solar Plants
Ground-mounted designs can accommodate this large-format module where row spacing, mounting height and surface reflectance support the intended layout.
Commercial and Industrial Roofs
Roof applications require checks on structural capacity, access, wind uplift and handling of a 32.4 kg module.
For demanding environments, confirm corrosion resistance, mechanical load ratings and approved mounting conditions.
630W Versus Other Wattages in the Same Series
The DT-33V-MHDRz family offers five output ratings in the same module dimensions.
| Model | STC Pmax | STC Vmp | STC Imp | Efficiency |
|---|---|---|---|---|
