WINAICO, a global PV module brand by the semiconductor company, Win Win Precision Technology Co. Ltd., officially opened its new global HQ Feb. 11 in Hsinchu, Taiwan. The occasion was marked by the launch of WINAICO’s unique micro-crack preventing HeatCap technology, and the highest density 300-W monocrystalline PERC module.
WINAICO is the first Taiwanese module manufacturer to reach 300 W in a single, 60-cell, solar module. The power output is confirmed by the leading Taiwanese research institute to be 302.8 W. WINAICO leads the world in high efficiency PERC module technology, proven by the <1% Cell to Module power loss (CTM power loss) achieved with the 300 W module. This CTM power loss is a significant improvement over the 3.5% to 5% CTM power loss common in competitors’ PERC module processes. WINAICO continues to work with leading Taiwanese solar cell manufacturers to push the boundaries of cell technology and improve scalability in mass production. WINAICO is one of the four module manufacturers in the world to achieve 300 W modules and will continue to strengthen the brand with technological leadership.
WINAICO’s internal evaluation showed evidences of HeatCap improving the ultimate stress a silicon solar cell can withstand up to 18.12%. WINAICO also worked with Taiwan’s leading research institute, ITRI, to evaluate the reliability of HeatCap technology through Dynamic Mechanical Load (DML) and local hot spot tests. HeatCap and reference modules were put through DML tests of 1000 cycles each at 1000 Pa, 2000 Pa, 3000 Pa sequentially, and verified by electroluminescence (EL) pictures. Compared to the reference module, the HeatCap module had significantly less micro-cracks after each stage of DML tests. Local hot spot tests provided evidence of HeatCap’s improvement in heat dissipation to reduce the solar cell temperature compared to reference cells. HeatCap can be used to solve the heating issue common to modules with black back sheets, and improve energy outputs of all-black modules in warmer environments.
“WINAICO continues to strengthen our brand with innovative technologies”, said Davis Chen, Chairman and CEO of WINAICO. “By reducing the CTM power loss to below 1%, we become one of the four companies in the world to achieve 300 W modules in the 60-cell format.”
