Helius Sunlink PV has been gaining increasing prominence in the production of photovoltaic modules. Since its founding in 2004, the manufacturer has produced the cells used in its modules in-house.
“Complete control of the production process allows for superior quality assurance at each stage, offering reliable and efficient products,” said Eduard Krummenauer, Country Manager of the manufacturer.
“The responsibility for every detail and the constant search for innovation ensure that the modules deliver the best performance, meeting customer needs with reliability and speed, since machine setup is extremely easy with the internal production of our cells,” he highlighted.
According to him, the cell manufacturing process is meticulous, involving a lot of research and dedication. Each step, from sawing the silicon ingot, doping the wafer, applying the electrical layers and assembling the module, is designed to ensure maximum efficiency and durability.
“In addition, cell manufacturing has evolved significantly. We started with lower efficiency cells, but as technology has advanced, we have been able to increase the energy generation per cell, seeking to increase power and yield. Technologies such as PERC and Half Cell have also been incorporated, allowing for the expected increase. Today, with cells of up to 210mm and the use of cutting-edge technologies such as N-Type, we guarantee greater reliability and longevity of our products,” he highlighted.
Over the course of its 20-year history, Helius has used a variety of cell types and sizes, including 125mm, 156mm, 158mm, 166mm and 210mm. The changes have been driven by both improvements in the production process and increased efficiency, which has varied between 15,7% and 23,8% over the years.
One of the recent developments that the company has implemented in its modules is the use of rectangular cells. This change was motivated by a key factor: greater use of the area.
According to the manufacturer, the rectangular cell adapts better to the geometric shape of a module, which allows them to fill almost the entire surface. With this change, Helius modules can deliver more energy per square meter, increasing the output power in projects and occupying a smaller area.
Participation in Intersolar
At Intersolar 2024, Helius presented its new models that use cells with Zero Busbar technology. This technology is an innovation in solar cell design, based on a super thinning of the busbars that brings significant benefits, such as higher yield, less cell shading and cleaner photovoltaic module aesthetics.
In practice, according to the manufacturer, a module with Zero Busbar technology can deliver an efficiency of 23,8% in an area of 3,1 m²: an increase of 3,7% in efficiency, while maintaining dimensions similar to other modules in the portfolio.
Furthermore, another highlight at the Helius stand at Intersolar 2024 was the presentation of the stages of the physical cell manufacturing process.
“Visitors to our stand were impressed by the physical materials we prepared to demonstrate the cell production steps. We had silicon wafers, an ingot, a wafer cut from the ingot, and two cells, all available for viewing and touching. We took the opportunity to share the information that we were able to produce around 20 containers of modules with the ingot on display,” recalled Eduard Krummenauer.
About a company
Helius Sunlink PV has been manufacturing solar s for 20 years and stands out precisely because it has total control over the production chain, from cell manufacturing to module assembly.
