NLR - Yingli 280W Mono Silver Frame Solar Panel


Out of Stock


Yingli Solar PANDA is a new monocrystalline silicon module technology with n-type solar cells that have average efficiencies higher than 19.5%. Combined with high transmission glass, module efficiencies are up to 17.1%. Compared to traditional modules with p-type solar cells, PANDA modules have lower initial degradation and higher performance under both high temperature and low irradiation conditions. Tight positive power tolerance of 0W to +5W ensures you receive modules at or above nameplate power and contributes to minimizing module mismatch losses leading to improved system yield. Top ranking in the “TÜV Rheinland Energy Yield Test” demonstrates high performance and annual energy production.
