Sabine, Victoria who will be next? The next storm is as certain as the sunrise

In recent years a series of storms have swept across Europe. The list comprises some prominent storms in Germany like hurricane Niklas (2015), storm Xavier (2017), hurricane Friederike (2018), hurricane Sabine, and storm Victoria (both in 2020). During the last hurricane named Sabine, winds reached speeds of up to 177 km/h. Even in the lowlands, speeds of around 150 km/h could still be measured. This is a good enough reason for us to take a closer look at the calculation of PV systems. Because one thing is for certain – there will be more hurricanes on the way!

Static friction coefficient with AeroFix and AeroFlat

Static friction and spring scale

In the flat roof sector, aerodynamic mounting systems have evolved, especially for foil, bitumen, green and gravel roofs. The reason for this success is the simple assembly compared to other systems, as normally no roof penetrations have to be made and better load values are achieved through the aerodynamics. Instead, ballast is only applied depending on the project. In this context, the so-called static friction coefficient between the bracket and the roof cladding plays an important role in all aerodynamic systems on the market, for example in our IBC AeroFix and IBC AeroFlat systems, because it strongly influences the ballast. How this is determined exactly and what needs to be taken into account is explained in more detail below. (more…)

Module trends and technologies: Cast Mono

The photovoltaic market has increased significantly over the last decade. In 2015, the annual PV installation was over 50 GW and the solar cells made with Multi Crystalline Silicon (mc-Si) had a market share of nearly 60 %. This year, however, the majority of European countries noticed a significant switch to Mono Crystalline Silicon with ratios of ~70 % in comparison to 30 % mc-Si. Regardless of the technology, one aspect is absolutely clear: the market is still going the direction where customers worldwide require higher efficiencies. The prices, however, have to stabilise or should get lower. By fulling this demand, cell and solar module producers are required to provide a solution to offer higher efficiencies at the same or lower level of prizing. In Sep 2018 we introduced you to our new module technologies which includes Half Cell, Multi Busbar or optimized cell connector like LRF. This time we want to take a closer look the Cast Mono technology.  (more…)

A visit to the IBC SOLAR test facility IV: bifacial test systems

A walk through our test facility allows you to immerse yourself in the history of photovoltaics. Many previous generation modules , some already now a decade and a half old, show how technology has advanced. In our blog series, guest author and product manager René Schüler presents special test objects and reports in our latest contribution together with Manuel Baier about the latest system at our facility. In addition to the previous crystalline poly- and mono- solar modules, so-called bifacial modules have now also been inspected at the open-space test facility. (more…)

Blog series ‘Quality inspection for modules’ part III: 50 days of fluctuating temperatures

The Ironman for photovoltaic modules takes place every day in our own quality control laboratory.  After all: We only offer the very best IBC SOLAR modules! In order to achieve this accolade, the modules must pass a series of endurance tests. In the third article of the series, we go into more detail about the temperature cycle test from our climate chambers.(more…)
