Product Description

440w Monocrystalline Solar Panel


1.Product Introduction

440w Monocrystalline Solar Panel withhigh efficiency, as with the conventional package, the half-sheet package is packaged in tempered glass, EVA and backplane. A conventional solar panel usually consists of 60 0.5-0.6V solar cells connected in series. The voltage is increased in series, so the 60 pieces work at a voltage of 30-35V. If half the cells are connected together, as in standard modules, they produce half as much current and twice as much voltage.

3.Product Feature And Application

The half cut cell distributes internal current in the system and improves its performance, life and shadow tolerance.

When one of the batteries in a battery string in a module is obscured, the battery forms a hot spot in the circuit, and sustained high temperatures may damage the module. Since there are twice as many battery strings in a half piece assembly, this means that the heat in the hot spot is only half as hot, and the lower heat does less damage to the assembly, thus improving the resistance to hot spot damage and increasing the service life of the assembly.

For now the 440w Monocrystalline Solar Panel is main use in the houseroof . Many europea customers like the monocrystalline solar panel.

4.Product Details

The use of half cells can provide great advantages and improve performance under shadow conditions, which is of great significance for the overall increase of photovoltaic power generation in buildings that are easily affected by other building obstacles.

A half-chip battery can increase the amount of energy produced, but its system design is similar to that of a full-chip module, ensuring a lower LCOE with no additional installation cost. The improvement of laser cutting technology makes the cutting defect of half a cell almost negligible. 

With the popularity of large components and large silicon chips, the trend of half or even three pieces is more and more obvious. According to industry related agencies, the next three and a half years of component market share is expected to exceed 50%
