The solar panel (also called solar cell module) is an assembly of multiple solar cells

The solar panel (also called solar cell module) is an assembly of multiple solar cells, which is the core part of the solar power generation system and the most important part of the solar power generation system.

Monocrystalline solar panel

The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all types of solar panels, but the production cost is so high that it cannot be widely used in large quantities. used. Since monocrystalline silicon is generally encapsulated by tempered glass and waterproof resin, it is strong and durable, and its service life is generally up to 15 years, up to 25 years.

Polycrystalline solar panel

The production process of polycrystalline silicon solar panels is similar to that of monocrystalline silicon solar panels, but the photoelectric conversion efficiency of polycrystalline silicon solar panels is much lower, and its photoelectric conversion efficiency is about 12% (on July 1, 2004, the efficiency of Sharp's listing in Japan was 14.8%). of the world's highest efficiency polycrystalline silicon solar panels). In terms of production cost, it is cheaper than monocrystalline silicon solar panels, the material is simple to manufacture, power consumption is saved, and the total production cost is lower, so it has been greatly developed. In addition, the service life of polycrystalline silicon solar panels is also shorter than

that of monocrystalline silicon solar panels. In terms of cost performance, monocrystalline silicon solar panels are slightly better.

We offer high quality solar panel from 70W to 10kw，like 2kva solar panel price is about $580，and bulk solar panels price is more competitive .
