72 Cells 320W Polycrystalline Or Monocrystalline Solar Panel
Polycrystalline or Monocrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced texturing process provides polycrystalline or moncrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed.

Main Features
1. Positive power tolerance (0~+5W) guaranteed.
2. High module conversion efficiency.
3. Low LID.
4. Better energy yield with excellent low irradiance performance and temperature coefficient.
5. Adaptable to harsh environment: passed rigorous salt mist and ammonia tests.
6. Robust frame(40mm) withstands mechanical loading of 5400Pa for snow load on front and 2400Pa for wind load on rear side.
