LONGi releases high-efficiency Hi-MO 6 PV module

Leading solar PV manufacturer LONGi has released its latest generation module, the high efficiency Hi-MO 6 – the company’s first module designed exclusively for the global distributed consumer market.

The Hi-MO 6 features LONGi’s high-efficiency HPBC (hybrid passivated back contact) cell technology and achieves a maximum efficiency of 22.8 per cent in mass production.

HPBC is a new generation of high-efficiency solar cell technology that is unique in its frontside busbar-free design. The cell technology improves its light absorption and photoelectric conversion capabilities by adjusting the cell’s internal structure, effectively increasing the module’s output power.

Modules equipped with HPBC cell technology can generate a greater volume of energy under high temperature and low irradiation conditions.

In global power generation simulations, Hi-MO 6 modules demonstrate a comprehensive power generation advantage over PERC (passivated emitter and rear cell) products, with an average power generation increase up to 10 per cent.

The modules feature back-contact soldering technology, which uses a one-line soldering structure rather than the traditional Z-shaped structure to enhance resistance to cracking.

The Hi-MO 6 includes four series – Explorer, Scientist, Guardian and Artist – all in the standard M10 size (182mm) and available in 72C, 66C, 60C and 54C types.

The module also offers the option of enhancing safety and optimisation by pre-installing the Smart Optimizer, meaning in the event of a PV system failure or module shading, the backend system may be remotely monitored and optimised in real time using feedback from the Smart Optimizer’s “digital brain”.

LONGi’s national sales manager in Australia, Brett Robinson, says the Hi-MO 6 builds on the company’s legacy since it was founded in 2000.

“Three guys started the company and they really love silicon,” he tells EcoGeneration. “They love cells, they love wafers and everything we do builds upon our heritage.

“This new high-efficiency HPBC back-contact product takes the busbars off the front and puts them around the back. It is high on efficiency and high on value.

“It is a great time to be in solar. We build on everything we have done in the past. Some brands can be dismissive of where they have been, but not us.

“We have history as a module manufacturer, but also a history as a supplier to other module manufacturers. We know this stuff back to front.

“We spend so much on research and development, with 900 engineers based in China and in other markets. We have a market-leading product here.”
