夏普推出了NU-JD440太阳能电池面板。这是一款半切单晶硅PERC产品,具有19.9%的效率和440W的功率输出。
公司透露,这款组件具有144个基于M6硅片的半电池,采用九主栅设计,正功率容差高达5%。这款通过IEC/EN61215和IEC/EN61730认证的面板整体尺寸为2108 x 1048 x 40毫米,重量为25.5千克,工作温度系数为每摄氏度-0.34%。
面板可用于最高电压为1500伏特,工作温度在-40至85摄氏度之间的光伏系统,并提供25年线性功率输出保证和15年产品质保。
这家日本制造商透露,这款半切组件采用三个,而不是一个小接线盒,均带有旁路二极管。该公司称,这些附件向上层电池传递的热量更少,有助于延长面板的使用寿命,同时提高系统的整体性能。
夏普能源解决方案欧洲公司产品开发经理Jens Meyer表示,NU-JD440可以帮助一系列应用降低平准化电力成本。
“得益于我们不断更新的产品组合、来自德国团队的支持,以及我们在欧洲、非洲和中东等地区提供的服务,夏普的客户能从最大的附加值中不断获益,”Meyer表示, 今年1月,夏普推出了采用半切电池的首个单晶硅PERC组件系列。随后,它又在2018年4月发布了据称效率为19.1%的三款单晶PERC产品。而在两年前,夏普在采用异质结和背面接触技术的电池中实现了25.09%的转换效率,并通过了日本电气安全环境研究所的认证。
