Product FAQ

How many Leapton Solar 445 panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 445W 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.

What is the efficiency of Leapton Solar 445?

This panel has an efficiency of 22.79%, using TOPCon, 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 Leapton Solar 445?

The module dimensions are 1722mm × 1134mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is Leapton Solar 445 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.
