Mono solar panel

You are here: Home >> Products >> SOLAR PANEL >> Mono solar panel
Name:320w mono panel
Category:Mono solar panel
 Mono panel efficiency is about 18.5%, the highest reached 24%, the manufacturing cost is higher than poly panel, that it can’t be widespread use.Because to the commonly used single crystal silicon and waterproof resin toughened glass encapsulation, so its durable, generally can be more than 25 years service life
Description Parameter
mono solar module often a deep black ,  usually by 125 * 125 mm and 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.mono solar modules are widely used in solar power generation system and all kinds of solar lamps and lanterns.
