72 Cells Poly Solar Panel 330W

Short Description:

156.75mm Poly Solar PV Module

The first solar panels based on polycrystalline silicon technology entered the market in 1981. Polycrystalline solar panels are made by melting several
fragments of raw silicon together. Melted silicon is then poured into square moulds and cooled. These are then cut into perfectly square wafers that
are used in the solar panels. Polycrystalline solar panels do not use a single crystal of silicon.
In common parlance, polycrystalline solar panels are also known as multi-crystalline, or many-crystal silicon panels, names that are derived from
their manufacturing technology. The presence of multiple crystals in each cell restricts the movement of the electrons, which leads to polycrystalline
solar panels having an efficiency level lower than that of mono-crystalline panels.

Product Details

Monocrystalline solar module advanced surface treatment technology, low surface reflectivity and 5bb cells design, lower series resistance and higher conversion efficiency.
The efficiency value is directly related to the power rating and the size of the solar panel. Let’s imagine we have a panel with a specific size and power output. If we increase the efficiency, then it means the panel will need less space to produce the same amount of power. In other words, the module will have the same size, but its power output will be bigger.
On the other hand, if we reduce the efficiency of the solar panel, then it means that the PV system will need to cover more space since the solar panel will have the same size but will have a lower power output. Therefore, selecting the appropriate panel model according to the efficiency rating can have a significant impact on the power output of your PV system, drive important space reductions and, increase annual energy yields.
