Regitec RMHT72/580S1 – 580W N-Type TOPCon Half-Cell Solar Panel

The Regitec RMHT72/580S1 is a 580W, high-efficiency N-Type TOPCon module built on a 144 half-cell (182 mm, 16BB) platform. Engineered for commercial/C&I rooftops, ground mounts, and large residential arrays, it delivers maximum watts per module, lower BOS costs, and dependable real-world performance. Each pallet contains 31 panels for streamlined logistics.

• Large residential arrays with limited roof area but high kWh targets

Compatibility & Design Notes

• Inverters/MLPE: Use string inverters, optimizers, or microinverters rated for ≥580 W input and within the Voc/Isc limits above.

• Rapid Shutdown: Pair with UL-listed MLPE where required by local code.

• Racking: Compatible with mainstream roof and ground systems; follow clamp zones and load tables.

• Stringing: Validate series count at site low temps (Voc) and ensure MPPT input current limits are respected.

FAQs

Can I use this with microinverters or DC optimizers?
Yes—select MLPE rated for high-power, high-current modules and confirm input specs fit the values above.

Is it suitable for harsh climates?
Yes—mechanical ratings of 5400 Pa/2400 Pa and IP68 components support snow/wind zones and challenging environments.
