KLD-NW SERIES

BIFACIAL SOLAR ENERGY

PV MODULE（490-715W）

Safe Reliable

PRODUCT DESCRIPTION

KLD-NW series bifacial PV module can make better use of solar energy resources. Each side of the bifacial module has been specially designed to maximize the absorption rate, which can increase the efficiency by up to 20%.

PRODUCT FEATURES

Safe and Reliable

Single-crystal silicon cells with low risk of hot spots can effectively minimize the impact of power output when the panel is shaded by shadows.

Higher Power

210mm silicon wafers and 132/120 bifacial half-cut cells for higher power generation.

Higher return

Gains are increased by generating power at the both sides, higher power generation and lower system cost can reduce the levelized cost of energy.

Easy installation

N type, bifacial and 210 optional; suitable for various types of roofs; fixed and tracking type optional.

HIGHER RETURNS

Gains are increased by generating power at the both sides, higher power generation and lower system cost can reduce the levelized cost of energy.

Temperature index-0.29%/℃

Bifacial modules with up to 20% returns, higher efficiency and more power generation.


N/P module real-time ambient temperature
