As one of the world’s largest solar Photovoltaic (PV) panel manufacturer, Yingli Solar is committed to delivering the best quality solar panels available.
With more than 15 years of solar PV manufacturing experience and three world-leading solar R&D facilities in the US, Spain and China, they are at the forefront of new solar energy technology.
Using the best quality solar components available and industry-leading equipment from Europe, the United States, Taiwan, Japan and China, they stand behind their promise of quality workmanship and technological innovation.
Yingli's fully automated production line and commitment to constantly improving our solar manufacturing process guarantees unbeatable quality, efficiency and durability.
Yingli Solar panels undergo vigorous testing including:
- Flash testing at every stage of the production line to ensure that every panel that leaves their factor is of the highest quality
- Marathon durability testing by TÜV Rheinland demonstrating that their solar panels surpass International Electro technical Commission (IEC) standards by up to six times
- World-class in-house solar PV testing and reliability laboratories in USA, Spain and China guaranteeing that they are constantly evaluating, re-evaluating and innovating to produce the highest energy outputs from their solar panels.
Their world-class solar panel production facilities are located throughout China with factories in Baoding, Haikou, Tianjin and Hengshui and are supported by an expansive global supply chain.
Yingli are one of the world’s largest companies manufacturing silicon solar panels along the entire PV value chain, from polysilicon to panel assembly.
Fully automated production of ingots, wafers, solar cells and solar panels ensures tight control of our material and production quality, while providing us with significant cost advantages.
Further, central production eliminates the environmental costs of transportation, breakage, and packaging.
Benefits of vertical integration include:
- Strict quality control measures at all stages of the manufacturing process
- Elimination of redundancies
- Reduced carbon emissions
- Continuous process and cost optimization along the PV value chain
In addition to Yingli's main PV solar manufacturing site at the Company’s headquarters at Baoding in China’s Hebei Province, they also operate the following:
Hainan Manufacturing Campus
Hainan Yingli New Energy Resources Co., Ltd was founded in September 2009 in order to expand Yingli's manufacturing capabilities.
In July 2010, Hainan Yingli completed construction of its Phase 1 manufacturing facility, located in Haikou City, in the Hainan Province of China.
With an annual production capacity of 400 MW, the facility covers the entire solar PV value chain from ingot casting and wafering, to solar cell production and solar panel assembly.
Tianjin Manufacturing Facility
Yingli Green Energy founded Tianjin Yingli New Energy Resources Co., Ltd. in March 2011.
It is located in Binhai Technology Park, in the High-Tech Zone of Tianjin.
The facility covers ingot casting, wafering, solar cell, module assembly and application system.
Currently, the total production capacity is 300 MW.
Hengshui Manufacturing Facility
Hengshui Yingli New Energy Resources Co., Ltd. is located in Hengshui Economic Development Zone, Hebei Province of China.
Currently, the total capacity is 150 MW.
The facility covers ingot casting and wafering, to solar cell production and module assembly.
Fine Silicon Facility
Fine Silicon Co., Ltd., their in-house polysilicon plant, began commercial production of high-quality solar-grade and electronic-grade polysilicon in August 2010.
The Baoding-based factory’s advanced monosilane-based technology and closed-loop manufacturing process enable significant energy savings and a low environmental impact compared with traditional tricholorosilane (TCS)-based polysilicon technology.
Fine Silicon Co., Ltd. currently has a designed annual production capacity of 3,000 MT.
Research & Development Labs
Yingli Solar Photovoltaic Research, Development, and After-Sales Center, Madrid
In October 2011, Yingli Green Energy opened the photovoltaic industry’s largest R&D and after-sales service centre, which is located in Madrid, Spain.
As the only solar panel manufacturer to establish its own comprehensive product evaluation, testing, and service facility in Europe, Yingli Green Energy delivers enhanced client service to European customers through every stage of the project lifecycle.
The Yingli Solar PV Testing Lab
Yingli’s PV Testing Lab is one of the industry’s most sophisticated product testing laboratories. We provide the services and assurance you need most when system performance is on the bottom line.
Inside Yingli’s PV Testing Lab in San Francisco, CA
When you visit, you will recognize that PVTL’s state-of-the art equipment enables performance and durability testing far more comprehensive and rigorous than industry-standard. Here’s a look at four pieces of equipment that are helping us lead the industry in R&D
HALM Solar Simulator With Integrated Temperature Control
Yingli is the first PV manufacturer to invest in this cutting-edge ash tester. With integrated temperature control, the HALM solar simulator is unparalleled in providing a robust picture of a panel’s response to temperature and irradiance (i.e., light conditions). Armed with accurate performance characterizations, you can confidently predict performance in your specific solar project locations.
Dynamic Mechanical Load Tester
This leading edge technology from specialized equipment vendor Eurotech subjects panels to dynamic mechanical loads, or multi-directional forces, which literally push and pull panels in various directions. This enables us to better understand the possible impact of real-world field conditions.
Yingli’s environmental chambers are designed for accelerated stress tests that allow us to better understand how panels can perform under prolonged exposure to environmental stress related to temperature and humidity.
By operating four chambers simultaneously, we can conduct extended durability tests that last hundreds of cycles beyond certification requirements.
Long-Term Outdoor Test Arrays
Yingli has 80+kW of long-term outdoor test arrays to evaluate PV panels and prototypes, along with a range of different Balance-of-System (BoS) equipment and distributed electronics. We designed our own custom Data Acquisition System (DAS) to measure system performance minute-by-minute.
With 27 separate strings of panels and a research-grade weather station, we can analyse over 15 million data points per minute from different panels alongside detailed weather insights. With these arrays, we can put our .PAN files to the test and validate our predicted energy yield.
