Polycrystalline solar modules improve performance

The module moves from a three to a four busbar cell architecture design, resulting in shorter current distance and less resistance loss within each cell. This yields greater energy efficiency and higher module power output. The nominal rated power of the 60 cell HSL S module is 260-270W, whilst the 72 cell module offers 305-315W.

The improved temperature coefficient of the modules reduces efficiency loss in high temperature climates, from -0.43 to -0.41% per degree Celcius, and the weak light performance at 200W/m² in relation to 1000W/m² improves to at least 97%. This enables the modules to harvest more energy during periods of lower light.

Uniformity and consistency in quality will be achieved as the modules will be produced entirely on automated lines, with an increase in the first year power warranty from 97 to 97.5% offered. Despite a slimmer frame design, the highly resilient aluminium alloy from which the modules are constructed delivers a 5.400/4.000Pa mechanical load resistance, ensuring durability is maintained even under challenging conditions.
