Poly solar panel

You are here: Home >> Products >> SOLAR PANEL >> Poly solar panel
Name:310w poly solar panel
Model:SR156P310
Category:Poly solar panel
Brief:

Poly panel efficiency is about 18.0%,the manufacturing cost lower than mono solar panel, that it can be

widespread use.Because to the commonly used poly cells and waterproof resin toughened glass encapsulation, so its

durable, generally can be more than 25 years service life

Description Parameter

Poly solar module often a blue ,  usually by 156 * 156 mm cells in series and parallel welding  , according to the

product need to be able to make into different size and different voltage, can charge to 6 v, 12 v, 24 v, even

higher voltage of battery, also can be connected to form large power station.poly solar modules are widely used in

solar power generation system and all kinds of solar lamps and lanterns.
