What is Poly Solar Panel?

1 All kinds of solar panels have the same purpose: converting sunlight into electricity. Each solar cell is made of multiple silicon crystal fragments that are melded together during manufacturing, also called "multi-crystalline panels" or "polycrystalline cells". Poly solar panel has a lower price and very durable.

 

2 Aesthetic appearance with excellent efficiency based on innovative photovoltalic technologies;

3 High quality,strong aluminium frame, high-transmissivity low-iron tempered glass, strong aluminium frame Using UV-resistant silicon;

4 Poly solar panel has passed TUV, IEC61215, IEC61730, CE, PV CYCLE, ISO 9001:2008,ISO 14001:2004 and OHSAS18001.

 

Poly Solar Panel Multiple Successful Testing

Power and tolerance

0~+3w positive power tolearance guarantee

Resistance to the PID
Harsh conditions for 96 hours testing qualified (@85℃/85%）.For special severity installation environment, can meet higher standards

Stonger surface resistance to mechanical loads
Poly solar panel has passed the certification of 6000pa snow load and 3600pa wind load

High reliability and weather resistance
Through dust,salt fog,ammonia corrosion test,can effectively deal with the harsh environment.

The hail test
Poly solar panel passed the hail test with a diameter 

Lower temperature coefficient
Better temperature coefficient makes the power attenusation less at high temperature
