Polycrystalline Solar Panel

125mm Polycrystalline Siddhi Solar Panel- A polycrystalline solar panel is a device which can absorb energy from the sunlight. The solar energy absorbed by polycrystalline solar panel can be used to generate electricity, either for immediate use or for storage…

156mm Polycrystalline Siddhi Solar Panel- This series of polycrystalline solar panel is made by connecting 156mm polycrystalline solar cells. It is characterized by high photoelectric conversion efficiency and long service life.

Polycrystalline Solar Panel

Polycrystalline solar panels can absorb renewable energy from the sun and then convert the solar energy to electricity. During this process, polycrystalline solar cells or photovoltaic cells play an important role. These solar voltaic cells are arranged in a grid-like pattern on the surface of solar panels and can collect sunlight during daylight hours.

Polycrystalline solar panel can not only help you reduce your electricity cost, but also protect our living environment.


Salient Features of Polycrystalline Solar Panel
