Features of solar panel

Polycrystalline or Monocrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced texturing process provides polycrystalline or moncrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed.


Solar panel is super energy saving and makes people life happy

Solar panel helps us to take full advantage of solar energy which is clean, inexhautible and pollution-free, and it converts sunlight into electric. In this way, we can help people in remote areas without mains supply and lack of electricity, and light up nights and bring people hope there.
