Polish premiere of the SmartSun Energy HJT module with an impressive power of 730 Wp

SmartSun Energy introduces a new photovoltaic module to the Polish market, boasting a record power of 730 Wp with an efficiency of 23.50%. The product is based on cells made in heterojunction technology (HJT) and Zero Busbar (0BB).

The latest photovoltaic modules are breaking records in terms of power output, and the widespread use of HJT technology allows for breaking new barriers. One of the market leaders in this respect is the SmartSun Energy brand, which has just started selling 730 Wp modules on the Polish market.

Advantages of the most powerful SmartSun Energy HJT module

The latest SmartSun Energy module combines many advanced technologies, the synergy of which has influenced the possibility of achieving such high power as 730 Wp. Among the key advantages of this product, it is worth mentioning:

- Record high power and efficiency, reaching 730 Wp and 23.50% respectively.
- The lowest temperature coefficient (-0.24%/°C).
- Very low degradation rate - only 1% loss of efficiency in the first year and 0.3% in each of the next 34 years.
- The highest bifacial coefficient, reaching up to 90%.
- Elimination of negative PID and LID phenomena.

What is HJT technology and what are its advantages?

HJT is the most advanced photovoltaic cell technology available on the market and the main reason why the latest SmartSun Energy module achieves such solid parameters compared to the competition. The use of heterojunctions means in practice the use of two types of silicon in the cell: monocrystalline N-type and amorphous.

This unique combination results in very high efficiency, as well as increased bifacial power generation capabilities. In practice, the HJT module is able to achieve up to 30% additional power gain due to bifaciality, which is a result unattainable for TOPCon and PERC cells.

It is also worth noting that the HJT cell design prevents PID and LID phenomena, which reduces the level of module degradation. Het-junctions also guarantee stable electricity generation even in high temperature conditions, which shows a favorable level of the temperature coefficient.

Unique Zero Busbar (0BB) technology

Another innovation in the latest SmartSun Energy HJT 730 Wp module is the use of Zero Busbar (0BB) technology, which allows for the complete elimination of busbars. Thanks to the patented cell connection technology, it was possible to reduce the resistance to current flow and increase resistance to so-called hot spots. This way, the effect was obtained in the form of increased module efficiency while reducing the degree of degradation.

35-year warranty and TÜV SÜD certification

In addition to excellent performance, it is also worth noting the warranty and certification issues of the new SmartSun Energy module. The manufacturer provides a 35-year warranty on both the efficiency and reliability of the product. The latest model has also passed the tests of the German organization TÜV SÜD.
