Description
xET-SOLAR Elite. 400W Monocrystalline Sola Panel. Half-Cut 108 Cells.
ET-Solar PV’s 400W solar module’s ingenious design creates a more durable, higher efficiency, and overall greater power production in comparison to many other solar modules/panels. The product has excellent performance properties in terms of the occlusion loss/temperature coefficient.
Half-cutting technology effectively reduces the hot spot risk of high-power components, resulting in better power generation, performance and reliability in system applications. The 182MM cell panels are half-cut, which means that they can absorb more sunlight and transfer more energy to the module in comparison to standard-cut modules. The 400W solar module boasts a module efficiency of 20.20% – which is greater than most regular solar panel modules.
What are the benefits of Half-Cell Panels from ET-Solar
High Voltage
UL and IEC 1500V certified; lowers BOS costs and yields better LCOE.
High Efficiency
Higher module conversion efficiency benefits from half-cell structure (low resistance characteristic).
PID Resistance
Excellent Anti-PID performance guarantee limited power degradation for mass production.
Low Light Performance
Advanced glass and cell surface textured design ensure excellent performance in low-light environment
Severe Weather Resilience
Certified to withstand: wind load (2400 Pascal) and snow load (5400 Pascal).
Warranty
25-years Linear Performance Warranty
10-years Product Material & Workmanship
1st year ≤ 2%, 2nd~25th years ≤ 0.55% / year
Advantage of PERC (Passivated Emitter and Rear Cell ) - Half Cut Cells
The traditional full cells have copper ribbons interconnecting the cells , half cell concept is proven to have more efficient way with lower resistance loss.
They also generate half the current of standard cells, reducing the resistive losses between the interconnections of solar cells. Less resistance means increased power output. The Solar-World Online confirmed up to 10W more power per module depending on the design.
With a higher power output on module that costs relatively similar, it shortens the return on investment (ROI).
Higher shade tolerance
Half-cut solar panels are more resistant to the shadow effect of cells. Instead of having 3-panel cell-strings in traditional solar panels, 6 strings are used to connect the cells in a half-cut solar panel. When there is a partial shadown on a panel, caused by leaves, branches or cloud, the shaded area will only affect a sixth of the total panel power output, instead of one-third of the output.
From 400W panels you loose only 66Watt.
With the traditional panel the power loss from shading will be 133Watt
Better durability
Half cut cells last longer, Firstly, smaller cells reduce the stress on cell copper connections expansion and contraction during a thermal cycle from hot to cold. There is a decreased opportunity for cracking. Also, half-cut panels reduce the hot spot temperature, thus lower the risk of damaging the panel.
