Maxwell Technologies (NASDAQ: MXWL), a leading developer and manufacturer of ultracapacitor energy storage and transmission solutions, was invited to attend the 2016 China International Conference on Integrated Photovoltaic Storage and Charging Power Plants (GES), where Dr. Yishan Li, Maxwell's Senior Application Engineer, delivered a presentation titled "Diversified Applications of Ultracapacitor Energy Storage Technology for Photovoltaic Applications". applications in the photovoltaic field". Dr. Li Yishan, Senior Application Engineer of Maxwell, delivered a speech entitled "Diversified Applications of Supercapacitor Energy Storage Technology in Photovoltaic Sector". In addition, Maxwell demonstrated its products and applications in PV energy storage and was awarded as "The Best Emerging Energy Storage Supplier of the Year in Photovoltaic Energy Storage and Charging Industry.

In his speech, Dr. Li Yishan explained the application of Maxwell supercapacitors in photovoltaic energy storage and successful examples. He pointed out that the output fluctuation of PV power generation process affected by weather will affect the quality of grid-connected power, while supercapacitor energy storage technology has the characteristics of instantaneous high-power charging and discharging, which can effectively suppress the fluctuation and stabilize its output to the power grid.

As PV power generation output varies within a minute, sometimes up to 40%, coupled with the complexity and variety of environments in which PV power plants are located, this has put forward higher requirements for supercapacitor performance. Maxwell supercapacitors are characterized by ultra-long service life, a wide range of operating temperatures, and high reliability and safety. Its newly launched 3V supercapacitors have a power density of up to 7.7kW/kg and a wide operating temperature range of -40℃ to 65℃, which can be more effectively used in photovoltaic power generation to meet customer needs.

Take the first phase of Maxwell's supercapacitor-assisted photovoltaic power generation project with the California Energy Commission (CEC) as an example: when the sun is blocked for a short period of time, the supercapacitor is capable of releasing instantaneous power to ensure grid stability. Installed in 2014, this project has reduced output power fluctuations to ±10%/min. Dr. Yishan Li revealed that because the first phase of the project worked so well, the second phase, which is five times larger, was also installed this year. In addition, the solar street light project using Maxwell supercapacitors has also been carried out in Mongolia, Indonesia, Guinea and so on. Compared with ordinary streetlights, solar-supercapacitor streetlights do not require the construction of power grids, can operate stably in extreme high and low temperatures, are maintenance-free and have a long life of more than 10 years.

The conference also featured discussions on other industry concerns and a series of awards recognizing outstanding companies in the PV storage and charging industry over the past year, with Maxwell winning the PV Storage and Charging Industry Emerging Energy Storage Product Supplier of the Year award for its leading products and pioneering application achievements.

"The characteristics of ultracapacitors make them ideal for use in new energy generation such as photovoltaics," said Dr. Yishan Li. "Maxwell has more than 15 years of practical experience in the power sector, and we look forward to cooperating with the Chinese government and more companies in the area of new energy generation. We look forward to working with the Chinese government and more companies on new energy power generation, and letting Maxwell's advanced experience serve more Chinese customers and promote the development of China's new energy industry."
