Cello technology by LG at Intersolar 2015

At the North America Intersolar Conference that took place in San Francisco, LG Electronics announced the innovative solar system LG NeON2 that will be available in US in August 2015. The LG NeON 2 was already awarded last month with the Intersolar Europe Photovoltaic Award. It is equipped with their newly developed “Cello” technology. “Cello” stands for Cell Connection, Electrically, Low Loss, Low Stress and Optical Absorption Enhancement.

During the press conference David Cheng, Senior Product Manager identified four (4) big improvements that come with the LG NeON 2 technology: increased reliability, upgraded durability, enhanced performance and improved efficiency in space management. The innovative cello technology utilizes 12 connection wires instead of just 3 busbars, which was the technology used in the previous LG solar panels. The new wiring design allows the panels to utilize scatter light more effectively for better absorption, while reducing the electrical loss by spreading the current over 12 cell busbars. As a result, of the improved temperature handling and power distribution, the LG NeON 2 can generate more electricity on a sunny day and performs better on cloudy days than prior panels. Whereas conventional p-type silicon modules suffer from Light Induced Degradation, the NeON 2 modules use n-type silicon material and uses the Multi–Wire Busbar cells for increased performance and reliability. This combination allow the annual degradation to be reduced by a up to 2 percent the first year and not more than 0.6 percent per year in the following 24 years. In addition they re-manufactured the design to give it a reinforced frame. As a result LG has extended the product warranty up to a 12 full years.

In San Francisco LG presented the flagship NeON 2technolgy that is available as a 320W residential panel. This product is ideal for the homeowner who wants to maximize the energy production potential within a limited roof space. Along with the residential product they introduced the Mono X NeON 72, well suited for commercial applications. Two models of the Mono X NeON 72 are designed to deliver outputs of 360 and 365 watts, in 72 cell 77-inch by 39-inch panel. This new series builds on the success of LG’s award winning 60-cell Mono X NeON panel.
