ET-Solar Elite PERC 355W Monocrystalline. Half Cut 120 Cells.

Half-cell panels are modules that have halved solar cells, a design that improves performance and durability. This means 60 and 72-cell panels will now have 120 and 144 half-cut cells. These cells are able to produce more power, as their current is also halved, and therefore losses incurred in resistance are reduced.

Smaller cells experience reduced mechanical stresses, so they have a decreased opportunity for cracking. Half-cell modules have higher output ratings and are more reliable than traditional panels. At Voltacon, we have begun investing in this revolutionary half-cell design, with the release of our Elios (Greek word for Sun) series of half-cell modules.

These monocrystalline half-cells will give higher efficiency and output — up to 366 watts in a traditional 60-cell footprint Our Tier One solar panel give you the flexibility to take back control of your energy needs. 

What are the benefits of Half-Cell Panels from ET-Solar 

High Module Efficiency:

Brings 5-10W power gain due to half cut production system with reduced losses.

Proven to Produce More Energy Yield:

Lower NMOT and better temperature coefficient by lower cell series resistance helps boost energy yield

Lower Operating Temperature, More Reliable:

 

Lower operating temperature and hot spot temperature during the sunny day, making the module prevail during the sunny days

Better Shading Tolerance:

Thanks to Paralleling circuit design, more power generated under shading condition and during morning & evening time

Better Micro Crack Resistance:

Minimize the impact by micro crack by limiting cell damage and potentially extending area by half-cut module architecture

Warranty

25-years Linear Performance Warranty

10-years Product Material & Workmanship
