3.Working Principle:

Features

4.Product Features:

1). The modules use high-quality imported polycrystalline or mono crystalline solar panel,enclosed by high rigidity tempered glass, with excellent light transmittance and output performance

2). Surface treated with reflection reducing process, increasing the light absorption. Back sealed with anti-aging EVA, resistant from moisture and corrosion.

3). High module conversion efficiency :our solar cell is over 17%, and solar panel is over 16%.

4). Long lifespan:our solar panel's lifetime is 25 years, 10 years at 90% output and 20 years at 80% output

5) Low light Performance: Advanced glass and solar cell surface allow for excellent performance in low-light environments

6) Severe Weather Resilience: Certified to withstand wind load(2400pascal) and sno load(5400pascal)

7) Free Solar Energy, Environmental Friendly
