Sungold 135w lightweight solar panels SG-PA621-135W
Featherweight Yet Resilient
By replacing glass with fiber-reinforced composite and polymer laminates, this 100W solar panel reduces weight and enhances its durability, providing long-lasting performance.
Robust Structural Integrity
Thanks to its innovative multilayer construction, the panel offers a flexural strength of ≥20MPa, ensuring exceptional durability and resistance to impact compared to traditional lightweight models.
Efficient Thermal Management
With a low thermal conductivity of 0.2W/(m·K), the backsheet minimizes heat transfer, ensuring that the panel performs optimally even under high temperatures and reduces energy loss.
Sustainable Materials for a Greener Future
Made from fully recyclable, PFAS-free materials and RoHS-compliant, this solar panel is an eco-friendly choice for those committed to clean energy and sustainability.

No. Stepping on it can cause debris, and damage to the cells creates localized heat and a high risk of burning the panels.
PA621 is waterproof to IP67, you can directly carry out rinsing or cleaning with a wet rag, pay attention to avoid the wiring.
You can choose different ways according to the application scenarios, Sungold provides common installation methods: sticking by 3M adhesive, fixed by the tie, fixed installation, bracket support installation.
Yes, lightweight solar panels are suitable for a wide range of applications with limited load-bearing capacity, reducing load-bearing pressure while maintaining a long service life.
Yes, cigs solar panels have a big advantage in bendability and weight.However, the price as well as service life is far worse compared to PA621, which is a more cost effective option if you plan to wholesale in bulk.
Yes, small solar panels are a better choice for users with limited installation space
It’s Anti Shade technology.Sungold’s latest solar panel technology introduced in 2024.
The junction box of Sungold 621 series solar panels has a built-in bypass diode, which has been functionally and thermally tested to ensure safety and reliability at high temperatures and under high load conditions. This ensures stable operation of the system in extreme environments.
