Frequently Asked Questions

What are the core technical benefits of your AR-coated tempered glass?

Our AR (Anti-Reflective) coated tempered glass features high transmittance and reduced light reflection, optimizing solar energy capture while offering robust protection against extreme environmental loads, impacts, and weather conditions.

Do you provide OEM services for global clients?

Yes, we support comprehensive OEM/ODM orders. We can customize specifications, incorporate your logo design, and adapt materials (such as backsheet colors and cell dimensions) to match your specific market requests.

How do you ensure the overall quality and reliability of the modules?

Every panel undergoes double EL (Electroluminescence) testing—both before and after the lamination process—followed by a comprehensive visual inspection and flash test to guarantee zero micro-cracks and precise power outputs.

What are the waterproof capabilities of your junction boxes?

Our modules utilize IP68 waterproof junction boxes. This ensures the highest standard of protection against dust ingress and water exposure, securing long-term electrical connections in all weather conditions.

Can these solar panels withstand heavy snow and strong wind pressures?

Yes, our panels are housed in anodized aluminum alloy frames designed to handle mechanical loads up to 5400 Pa (snow load) and 2400 Pa (wind load), providing exceptional structural stability.
