Product Details

Glass Laminated Polycrystalline Solar Panel Domestic Multicrystalline ZW-300W



Poly-crystalline modules designed for residential and utility applications, rooftop and ground mount.

Anti-reflective and self-cleaning surface reduces power loss from dirt and dust.

Excellent mechnical load resistance: certified to with stand high wind loads(2400Pa) and snow load(5400Pa)


Quick Detail:


Polycrystalline solar panel are also made from silicon. However, instead of using a single crystal of silicon, manufacturers melt many fragments of silicon together to form the wafers for the panel. Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. Because there are many crystals in each cell, there is to less freedom for the electrons to move. As a result, polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.


Zhiwang offer industry leading high performance and are designed specifically polycrystalline solar panel to meet clients’ demand for residential, commercial and industrial use from small installations to multi-megawatt power plants. Mainstream solar panel model 36 cells 150-180Wp,60 cells 250-280Wp & 72 cells 300-340Wp.


Saving money is one of the best reasons to solar, and whether you choose mono or poly solar panels, you’ll be decreasing your electricity bills. The option you choose comes down to your personal preferences, space constraints, and the financing option you choose.
