LA30-12S
High-efficiency PV Module
Technology
The LORENTZ LA-Series of PV modules with
monocrystalline silicon solar cells offer a high
conversion efficiency due to the unique backcontact
technology.
The low voltage-temperature coefficient guarantees
a superior battery charging performance,
even at high operating temperatures.
Exceptional low-light performance and broad
spectral response further enhance energy delivery
in all weather conditions, year round.
Features
aerospace style cell interconnects with in-plane
strain relief
advanced EVA encapsulation system with multilayer
backsheet for long-term package durabilit
bypass diodes to minimize the power drop
caused by shade
high reliability
Warranty
Warranty: up to 2 years
Performance guarantee:
up to 5 years (90% power output)
Details according to warranty
issued by LORENTZ
Standards
LA30-12S meets the requirements
for IEC and CE.
Applications
water pumping
water purification systems
remote village lighting
solar home systems
street and camp lights
traffic signals
medical facilities in
remote areas
microwave/radio repeater
stations
battery charging
