    18V Polycrystalline Solar Panel 20 Watt Mono Versus Poly Solar Panels

    20W-18V Polycrystalline Solar Panel 20 Watt Solar Panel Small Solar Panel

    Description:

    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.
