Factory wholesale Longi 550w Solar Panel - 72 Cells Poly Solar Panel 330W – Yifeng
Factory wholesale Longi 550w Solar Panel - 72 Cells Poly Solar Panel 330W – Yifeng Detail:
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.
