Product FAQ

How many DMEGC Solar DM640M10T-B78HSW panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 640W per panel, a typical 10kW residential system requires about 16 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of DMEGC Solar DM640M10T-B78HSW?

This panel has an efficiency of 22.9%, 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 DMEGC Solar DM640M10T-B78HSW?

The module dimensions are 2465mm × 1134mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is DMEGC Solar DM640M10T-B78HSW 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 DMEGC Solar DM640M10T-B78HSW come with?

This panel includes a 15-year product warranty from DMEGC 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.
