Highly efficient solar panels, lead-free modules and very efficient inverters for solar parks have made it to the podium of this year's Intersolar Awards.
These are the runners-up:
Gamesa Electric (Spain): Proteus PV4700 is a central inverter for large photovoltaic parks that combines high efficiency with particularly high-power density. Its hybrid cooling system consists of a liquid circuit for stressed components and air cooling. It ensures that the inverter operates at high outdoor temperatures without power derating. In addition, the central inverter has only low harmonic components in its output current and can even actively suppress certain harmonics, which makes it suitable for use at rather weak grid connection points.
M10 Solar Equipment (Germany): The Surface production line interconnects solar cells using the so-called shingle method. Solar cells cut into six strips are precisely connected to each other with a very small overlap of one to 1.2 millimetres using a conductive adhesive. The surface system can also position the solar cells in a brick pattern. The result is the so-called shingle matrix, which enables a slight curvature as well as shading-tolerant modules. In combination with colouring techniques, this opens up design possibilities for buildings and vehicles.
And the winner of the Intersolar Award 2022 is:
REC Solar EMEA (Germany): Alpha Pure is the first mass-produced lead-free solar module with crystalline silicon cells that complies with the EU RoHS Directive on the "Restriction of the use of certain hazardous substances in electrical and electronic equipment". Alpha Pure offers up to 410 watts of output with a size of 1.85 square metres, which corresponds to an efficiency of 22.2 per cent. This is achieved by combining the proven heterojunction solar cells with wire-based interconnection technology without gaps between the individual solar cells. (HS/mfo)
