PA621 -Zero Hot Spot Technology

Concerned about hot spot effects compromising your components? With Sungold, those worries are a thing of the past.

In a world where renewable energy is the future, Sungold® is here to help you lead the charge. With our flexible solar panels and unwavering commitment to your success, we’ll power your business and your customers’ lives with clean, reliable energy.

PA621-Zero Hot Spot Technology

Excellent heat insulation performance

Adopting multi-layer structure design, it has higher structural strength, and the bending strength is ≧20MPa. The thermal conductivity of the solar backsheet is 0.2W/(m.k), and the backsheet material provides low heat transfer performance, which reduces the impact of module power drop under high outdoor temperatures and improves the actual power generation.
Excellent Heat Insulation Performance

Robust and durable

The felxible solar panels 621 series  is up to 1300MPa, which is 100% higher than similar ordinary products, improving the overall strength of the module and solving the problem of hidden cracks in the cells..High frequency vibration resistance: 10- 60hz
