☀️ Main Features
590W High Power Output
Each panel provides up to 590W of rated solar power, making it suitable for large solar arrays.
N-Type Monocrystalline Technology
N-Type cells provide high efficiency and are well suited to modern solar installations.
Bifacial Energy Generation
The panel can generate electricity from both the front and rear sides. The current product listing indicates 10–20% additional rear-side gain where installation conditions provide suitable reflected light.
21.29% Efficiency
The high module efficiency allows more power generation from a given installation area.
IP68 Protection
The junction box is IP68-rated for protection against dust and water in outdoor installations.
Example Solar Array
- 5 × 590W = 2.95kW
- 10 × 590W = 5.90kW
- 20 × 590W = 11.80kW
- 50 × 590W = 29.50kW
- 100 × 590W = 59.00kW
For a 50kW 3-phase hybrid inverter, 100 panels would provide 59kW of installed PV capacity.
