Zhejiang Guangyi Optical Energy Technologies Co.,ltd. was established in 2001. From the year 2001 to 2006, Guangyi only designed, produced solar water heater.

In the way of global renewable energy developing, in the year 2006 Guangyi started to design, produce photovoltaic products. From the year 2006 to 2007, Guangyi solar module annual production capacity was 10MW. In the year 2008, 10MW capacity couldn't meet the needs of global renewable energy market, so Guangyi expanded its solar production line to 60MW annual capacity.

At the beginning of 2009, Chinese government carried out a series of excitation mechanism about renewable energy and energy-saving products. Seizing this opportunity, Guangyi expands again, and will have 300MW annual capacity of solar module, also begins to R&D, design LED light.

Now, Guangyi is specialized in R&D, designing, producing and selling solar panels, solar off-grid power systems, solar grid-connected power systems, LED, solar street light, solar traffic light, solar garden light and etc.

Guangyi takes environmental protection and innovation as our responsibility and mission. Although Guangyi is still young, Guangy's top-grade designers, professional R&D teams, strict quality management prompt Guangyi's development.

Today, Guangyi's products throughout the world. Guangyi not only makes production scale expansion every year, but also constantly update production equipment, to ensure the photovoltaic products become reliable energy solutions and benefit more customers.
