The number of panels depends on your energy consumption and roof area. At 440W per panel, a typical 10kW residential system requires about 23 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

This panel has an efficiency of 22%, using TOPCon, N-type cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.

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

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.

This panel includes a 30-year product warranty from HT-SAAE. 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.
