'Silicon Module Super League' (SMSL) member Canadian Solar has launched an innovative ‘cool’ PV module design, dubbed Ku Modules, the series is based on Low Internal Current (LIC) module technology. This is intended to reduce NMOT (NMOT: 43 ± 2 °C) and lower hotspot risks, resulting in better energy yield and reliability.
The new Ku Modules portfolio is available in both poly- and monocrystalline. Ku modules family consists of following types: KuMax (144 cells), KuPower (120 cells), KuBlack (120 cells) and the corresponding double-glass KuDymond. The KuMax modules have a power class up to 360 Watts.
Imec and EnergyVille
Imec and EnergyVille are introducing new simulation software that accurately predicts the daily energy yield of solar cells and solar modules under varying meteorological and irradiation conditions at Intersolar Europe.
Imec’s model combines optical, thermal and electrical parameters to provide detailed insight on thermal gradients in the solar module. The model integrates the effect of these gradients, resulting in a significantly better accuracy (root mean square error of only 2.5%) than commercially available software packages for energy yield estimation.
It can also be used to make a rapid assessment of material and technology changes at the cell and module level and their influence on the levelized cost-of-electricity (LCOE).
“It is an excellent tool to make a rapid assessment of material and technology changes at the cell and module level and their influence on the levelized cost-of-electricity,” noted Jef Poortmans, scientific director photovoltaics at imec. "Moreover, it is also the ideal starting point to come up with significantly improved short-term energy yield forecasting, which will lead to lower lost opportunity costs and better energy management systems for PV power plants as well as residential solar systems. This means that our model could e.g. become very useful for PV plant operators and electricity grid operators, enabling them to better forecast the short-term varying output of PV power plants, in this way limiting curtailment situations and grid balancing issues, and hence create more value across the full renewable energy value chain.”

Swiss-based Flisom is presenting a new, ultra-light, rollable and customisable CIGS (Copper Indium Gallium Selenide) thin-film solar technology platform.
The Flisom modules are super thin (under 2mm), have a uniform, jet black appearance and by nature are ultra-light (in some versions under 500g/m2). The company said it was gearing up for full-commercialisation of its product range this year.
AU Optronics Corp
Taiwan-based AU Optronics Corp (AUO) is showcasing its SunVivo mono-crystalline and SunPrimo multi-crystalline solar modules that were said to be manufactured locally in Europe. AUO established a solar module plant in Europe in 2010.
SunVivo monocrystalline and SunPrimo multicrystalline modules were tested for resistance to light induced degradation (LID) and showed LID of less than 2% in the first year of use. The modules also passed a 1,000-hour test for resistance to potential induced degradation (PID), demonstrating exceptional quality for stable power generation. These two types of modules, combined with an enhanced structural design, passed snow load and dynamic wind pressure tests to meet the requirements for the specific terrain, weather, and extreme environments in Europe.
The high-performance modules use a five-busbar design to allow faster current collection, increasing their power output. Notably, the SunVivo series offers a black module design consisting of only 60-cells to attain over 300 Watt power output.
