Tier one Chinese solar panel maker Longi has launched the Hi-MO X in Australia, with efficiency of 20%.

The module uses mono-crystalline PERC technology and “shingle” design adopted by Australian R&D partner UNSW in the solar-powered vehicle it engineered to win the 1996 World Solar Challenge.

The eliminates power losses caused by solder strip shading, the company said, “and a novel cell series-parallel circuit design significantly increases power generation performance in shaded conditions”.

The Hi-MO X modules are the first to meet the Clean Energy Council’s “enhanced listings” criteria, designed to favour premium-quality product.

At the launch in Melbourne CEC product specialist Sandy Pulsford highlighted degradation issues on backsheets of panels in hot global locations as a fault common among lower-tier modules.

“Premature back sheet degradation can affect the whole industry,” Pulsford said.

The Hi-MO X is made using DuPont’s Tedlar backsheet material, which pre-qualifies the panel for the CEC’s stringent new MAST certification.

The module is available in 400W (72-cell) and 350W (60-cell) peak power variants.

BayWa Australia, SolarJuice and SolarGain have been appointed official distributors for Hi-MO X in Australia.
