270W Polycrystalline Silicon Solar Panel

270W Polycrystalline Silicon Solar Panel
270W - 275W - 280W - 285W - 290W
KSUN Poly-Si Solar Panel 270W - 275W - 280W - 285W - 290W

• Excellent Low Light Performance

KSUN solar panel has great performance under low ligght conditions with advanced technology and high efficiency solar cells manufacturing, with low tolerance ensuring hightly consistent performing panels. 

• Improved High Temperature Performance

Solar panels slowly lose their ability to generate power as they get hotter. KSUN solar panel has an improved temperature co-efficient to standard modules, which means in hot weather KSUN solar panels will deliver higher output.

• Enhanced Performance Warranty

KSUN solar panel comes with an enhanced performance warranty. After 25 years of use, the KSUN solar panel is guaranteed to provide at least 90.6% of initial performance.

• Increased Output with HTAR Glass and Anti-reflective Coatings

KSUN uses HTAR glass (Highly Transmitted Anti Reflection) which has low reflectivity and high transmittance to increase power generation compared to AR glass used in previous models.
