45W-50W-18V Polycrystalline Solar Panel 50 Watt Solar Panel Solar Energy Panels
Product Description:
Polycrystalline solar panels generally have lower efficiencies than monocrystalline options, but their advantage is a lower price point. In addition, polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels. We has developed various types of polycrystalline solar modules. Polycrystalline Solar Panel have an advantage over monocrystalline silicon solar prices, but are less efficient.
Polycrystalline solar panels are made from similar silicon material hence instead of going through the slow and more expensive process of creating a single crystal, molten silicon is just put into a cast and cooled with a seed crystal. By using the casting method, the crystal surrounding the seed isn’t uniform and branches into many, smaller crystals, thus the term “polycrystalline”. The surface has a jumbled look with many variations of blue colour.
In general, we have a number of successful projects around the world, such as grid-connected power generation systems, off-grid power generation systems, and integrated power generation facilities. We have advanced, mature and stable supply lines to support your multi-faceted needs in the solar market.
