Product FAQ

How many Tongwei Solar (TW Solar) TWMNH-48HE460W panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 460W per panel, a typical 10kW residential system requires about 22 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of Tongwei Solar (TW Solar) TWMNH-48HE460W?

This panel has an efficiency of 23%, using N-type cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.

What are the dimensions of the Tongwei Solar (TW Solar) TWMNH-48HE460W?

The module dimensions are 1762mm × 1134mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is Tongwei Solar (TW Solar) TWMNH-48HE460W compatible with standard inverters?

Yes, these panels work with most string and hybrid inverters. However, you must check the Voc (Open Circuit Voltage) and Imp (Current at Max Power) against your inverter's MPPT specs.

What warranty does the Tongwei Solar (TW Solar) TWMNH-48HE460W come with?

This panel includes a 15-year product warranty from Tongwei Solar (TW Solar). Solar panels typically degrade about 0.4–0.5% per year, meaning this module should retain over 87% of its original output after 30 years.
