Technology & Performance Notes
HJT is a premium high-efficiency technology with very low temperature coefficient and bifacial gains. At 21.3% module efficiency the Meyer Burger MB 390W HJT converts 21.3% of incident solar irradiance into DC electricity, putting it in the mainstream efficiency tier for its class. The 212.0 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Meyer Burger MB 390W HJT into a string:
- Keep the string Voc (temperature-corrected to the coldest expected cell temperature) below the inverter’s maximum DC input voltage.
- Keep the string operating Vmp within the inverter’s MPPT window across the expected temperature range.
- Size fusing and conductors against Isc (12.6 A) with the standard 1.25x safety factor.
