Winners in the Photovoltaics category

Higher system output and easy to install – a highly efficient, bifacial solar module

Electronics manufacturer LG Electronics Deutschland GmbH is continuously expanding its business activities in the PV industry. Its new, highly efficient, bifacial solar module LG NeON 2 BiFacial significantly boosts energy yields and features NeON cell technology and 12-wire CELLO cell connection. In outdoor tests carried out and documented by LG Electronics under various, typical conditions, the modules were shown to increase yields by around 10%. The conventional, simple junction boxes are divided into three smaller boxes located outside the cell area, thus avoiding shading and heat build-up on the back of the module. The module is also relatively lightweight, making it easier to install. "Bifacial modules require less material and space for the same system output. This makes them a
worthy winner of the Intersolar AWARD 2016," said the panel.

The next logical step for module technology

The Germany-based company M10 Industries AG develops, produces and maintains manufacturing systems for the solar industry. As the only stringer in the world able to solder up to 5,000 solar cells per hour, the Kubus multi-tray stringer increases capacities dramatically. The Kubus system connects an entire module in a single soldering process, eliminates the need to insert individual strings and significantly minimizes cell handling. All components can be exchanged without interrupting the production process, which considerably reduces the amount of downtime.

The same system can be used to process numerous cell concepts with a different number of busbars, and can even be integrated into existing production lines. If the global energy transition is to succeed, the production costs of photovoltaics need to be reduced further to increase its share in the market. The panel of judges praised the innovation for its performance, low material consumption and the fact that it can be operated by just one person – all of which are factors that help to reduce the costs of photovoltaics.

Inverter with record-breaking efficiency

SolarEdge Technologies Inc. (Israel) is a supplier of inverter solutions for the international photovoltaics market. The company aims to increase the availability of solar energy. SolarEdge's HD Wave technology has enabled the development of a compact, lightweight inverter with a record-breaking efficiency of up to 99%. It uses multi-level technology with distributed switches to generate voltages that come very close to the sine wave of the grid voltage. This considerably reduces the number of magnetic components required. The silicon MOSFETs used for the multilevel switching ensure low switching and conduction losses, thus reducing cooling requirements. This allowed power density to be increased, whilst reducing the size of the inverter to around half that of most standard devices. SolarEdge anticipates lower production costs, thus considerably reducing the costs of one of the main components of a PV installation. The innovation won the Intersolar AWARD because the panel agreed that the innovation would have an impact on the entire PV value-added chain.
