Bifacial photovoltaic panel Ja Solar 605W N-type – JAM72D40, monocrystalline

Ja Solar 605W N-type Bifacial Solar Panel – JAM72D40 is a powerful photovoltaic module for modern solar systems. With a nominal power of 605W and high efficiency, it offers stable energy production for homes, commercial rooftops and large installations. The panel uses monocrystalline N-type TOPCon technology, which ensures lower degradation over time and better performance at high temperatures.

The bifacial design allows the module to capture both direct and reflected sunlight. This increases the overall energy yield, especially when mounted on bright or reflective surfaces. The panel is suitable for combination with inverters for grid-connected and off-grid systems, offering an excellent balance between price, power and longevity.

High efficiency and performance

This model achieves an efficiency of around 23.2–26%, making it one of the leaders in its class in terms of energy density and yield per kWh per installed surface area.
The monocrystalline N-type cells have a low temperature coefficient, which means that the panel maintains higher output on hot days and in partial shade.
The construction with 144 half-cells and double-sided glass provides additional mechanical strength and resistance to external influences.

Advantages of double-sided design

The double-sided design allows the panel to capture additional energy from reflected light on the back side. This can increase the total energy yield by up to 80% under suitable installation conditions and a reflective surface.
This feature is particularly useful for installation on white roofs, lawns or light surfaces where reflections contribute significantly to electricity production.
The additional energy revenue improves the return on investment and reduces the cost per kWh over the life cycle of the system.

Reliability and long life

The panel is designed with double tempered glass and an IP68 protected junction box, which guarantees high resistance to moisture and external influences.
The mechanical structure withstands snow loads of up to 5400 Pa at the front and wind loads of up to 2400 Pa at the rear, ensuring long-term operation even in harsh weather conditions.
The manufacturer provides a 12-year product warranty and up to 30 years of linear power warranty, with degradation limited to about 0.4% per year.
