HIGH EFFICIENCY MODULE
Voltage increase is an effective way to decrease line loss. To take advantage of
this, ET is developing high-efficiency modules, and using a variety of creative
techniques to upgrade voltage levels. ET’ s 1500VDC Module is designed to
deliver a lower LCOE to the power plant, by allowing longer cable operations and
strings to reduce the number of combiner boxes and make cable sizes smaller.

Designed for compatible with advanced
high voltage1500V plant architectures
Significant saving on BoS cost
Expanding string length up to 50%
Higher module efficiency up to 17%
Enhanced module durability
