Yingli 440 photovoltaic panel parameters

Who is covered by the Yingli solar installation manual?

This manual applies to photovoltaic modules (“PV modules”, also commonly known as solar panels) manufactured by Yingli Energy Development Company Limited (“Yingli Solar”), and is explicitly written for qualified professionals (“Installer” or “Installers”), including without limitation licensed electricians and RAL Certified PV Installers.

What angle should Yingli solar panels be mounted?

Yingli Solar recommends that PV modules be mounted at a minimum tilt angle of 10 degrees to allow for proper self-cleaning from normal rain showers. Partial or complete shading of a PV module or modules can significantly reduce system performance.

Can Yingli Solar PV modules be cleaned with a pressure washer?

Water with high mineral content may leave deposits on the glass surface and is not recommended. Yingli Solar PV modules may contain a hydrophobic anti-reflective coating on the glass surface to enhance power output and reduce dirt and dust buildup. In order to avoid module damage, do not clean PV modules with a power washer or pressure washer.

What should I do if my Yingli solar module fails?

Defects should be addressed immediately. Over time, dirt and dust can accumulate on the glass surface of the module, reducing its power output. Yingli Solar recommends periodic cleaning of PV modules to ensure maximum power output, especially in regions with low precipitation.

How much torque should a Yingli Solar System have?

The applied torque value should be big enough to fix the modules steadily, the torque of screw tightening should between 16 N·m to 24 N·m. Yingli Solar recommends that PV systems be periodically inspected by the installer, or other qualified person.

Is Yingli Solar liable for infringement of patent rights?

Yingli Solar assumes no responsibility for any infringement of patents or other rights of third parties, which may result from using Yingli Solar PV modules. No license is granted expressly or by implication or under any patent or patent rights.
