Lorentz 20Watt 12Volt Mono-crystalline Solar Module

Lorentz 20Watt 12Volt High Efficiency Mono-crystalline Solar Module


The LORENTZ LA-Series of PV modules offer a conversion efficiency of 17-20% due to the unique back-contact technology.


Our monocrystalline silicon solar cells yield a higher voltage per cell. Therefore 34 cells are sufficient to provide the same voltage as traditional 36-cell modules. As a result, LORENTZ modules are lighter and smaller.


In combination with an extremely low voltage-temperature coefficient, this 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.
