Trends in PV cells and modules

Module sizes and wafer sizes in transition

The trend continues: You can see that bigger and better is still possible.

Wafer sizes of 182 mm (M10) and 210 mm (M12) have now arrived on the market. With the new cell sizes, new performance classes are emerging. Modules with these wafer sizes are expected to become established in the long term and will account for the majority from 2022/2023. What counts for us and our customers, especially in the roof segment, is efficiency. The efficiency of the modules is constantly being optimized by larger wafers and efficiency is being increased.

Of course we go along with it. We rely on strong brands and quality. Discover our new modules in the Krannich portfolio:


SolararEdge revolutionized the photovoltaic industry by inventing a better way to collect and manage energy in PV systems. Today, they are a global leader in smart energy technology.

SolarEdge power optimizers can be used to get the maximum power out of any PV system. With these modules, the optimizers are already installed, making system configuration a breeze. All that remains is to select the appropriate inverter. The Smart modules are based on half-cell technology for increased performance and durability. They are available with either a black frame or an all-black front for an even more elegant look.

The modules with integrated power optimizer deliver up to 375 W of power with a 15-year module warranty.

All advantages at a glance:

  • Performance guarantee: 25 years
  • Faster installation for rooftop installations - no separate mounting of power optimizers required
  • Faster mapping of the physical plant layout - simply scan the serial number on the front of the module
  • Streamlined logistics with fewer parts, easier service support and a single product warranty
  • Module level monitoring
  • Rapid shutdown at module level for optimal safety

Meyer Burger

With 40 years of experience in photovoltaics, Meyer Burger has set significant standards over the past decades. Meyer Burger has further developed the existing heterojunction (HJT) cell technology and made it more efficient. By combining different silicon layers, a unique cell structure has been created. The HJT cells thus absorb significantly more solar energy than conventional cells and the converted electric current flows through the module with less resistance.

The heterojunction cells are combined with the patented SmartWire technology. The high-efficiency PV modules feature excellent low-light performance and high resistance. In addition to an extraordinarily high efficiency, they also have a significantly longer life expectancy. The modules are produced exclusively in Germany.

Meyer Burger high-performance modules:

Meyer Burger White, rated power 380 - 400 Wp
Meyer Burger Black, rated power 375 - 395 Wp
Meyer Burger Glass, rated power 370 - 390 Wp


At a glance:

  • Maximum performance: Up to 20 percent more energy yield - even in low light conditions, in the morning or evening, or when it is cloudy
  • Maximum quality: Production of solar cells and modules to the highest standards exclusively in Germany
  • Maximum endurance: Guaranteed yields over decades
  • Maximum stability: Patented SmartWire technology makes modules maximally resistant and powerful
  • Maximum elegance: Discreet and superior design - developed in Switzerland
