Yingli Launches Hotspot Free Series Module at the PV Expo 2017

Yingli’s Hotspot Free module can eliminate potential safety risks such as fire and material degradation, and ensure better safety; better module reliability and higher returns.

Yingli Green Energy Holding Company Ltd. announced a Hotspot Free Series Module at the PV Expo 2017. Yingli’s Hotspot Free module can eliminate potential safety risks such as fire and material degradation, and ensure better safety; better module reliability and higher returns said the company in a statement.

The Hotspot Free technology is based on a concept whereby each cell is protected by a bypass diode. In any case that the current of a single cell doesn’t match the rest of the string, for example because that cell is shaded, the bypass diode will be activated and will ensure that the other cells can still work properly and prevent the affected cell from heating up. Beside, being a safety feature, less heat also means less stress for the materials, leading to a longer lifespan of the whole module, which improves performance ratio and increases yield for the investors.

Yingli also highlighted their PANDA Bifacial module at the trade show. The PANDA Bifacial module can generate power on the front and rear sides, which for example have been proven by a 50MW top runner project in Datong, Shanxi province, in China.

The PANDA Bifacial module possesses strong durability and resistance to PID (Potential Induced Degradation) and performs well in various harsh environments of high temperature and humidity, salt mist and sand. With a maximum system voltage of 1500 Volts (V), the PANDA Bifacial module can improve system performance and reduce the balance-of-system costs by up to 25%.

“It is wonderful that we have such high performance modules. They can not only generate more power but also enhance safety and increase returns. We will do our best to promote them everywhere in Japan to give our customers the best products and highest returns,” said Yamamoto Joji, Master Director of Yingli Green Energy Japan. “Yingli will always be committed to reducing the cost of solar power generation and making solar electricity affordable and accessible for all through continued technology innovation.”
