Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electricity through the photoelectric or photochemical effects.
The main material of most solar panels is “silicon”, but because of the large production cost, there are limitations to its general use.
Compared to ordinary batteries and rechargeable batteries, solar energy is a more energy-efficient and environmentally friendly green products.
Mono crystalline Solar Panel
Mono crystalline silicon solar cells, which are solar cells made of highly pure mono crystalline silicon rods, are the fastest developing type of solar cells at present. Its structure and production process have been finalized, and the product has been widely used in space and on the ground.
More than 91% electrical output conversion rate, mono crystalline efficiency of 19.6%.
Mono crystalline solar panels have high cell conversion efficiency and good stability, but are more costly.
In addition, the service life of poly crystalline silicon solar cells is also shorter than that of mono crystalline silicon solar cells.
In terms of performance-to-price ratio, mono crystalline solar cells are also slightly better.
Mono crystalline silicon cells are rounded or tangled at the four corners, with no pattern on the surface;
Poly crystalline Solar Panel
Poly crystalline solar panels are solar modules made of high conversion efficiency poly crystalline silicon solar cells arranged in different series and parallel arrays.
The production process of poly crystalline solar cells is similar to that of mono crystalline solar cells, but the photoelectric conversion efficiency of poly crystalline solar cells is much lower, with a photoelectric conversion efficiency of about 16%.
In terms of production cost, it is cheaper than mono crystalline silicon solar cells, easy to manufacture materials, save electricity consumption, the total production cost is lower, so it has been developed in large quantities.
In addition, the service life of poly crystalline silicon solar cells is shorter than that of mono crystalline silicon solar cells. In terms of performance to price ratio, mono crystalline solar cells are also slightly better.
The cost of poly crystalline silicon cells is low, and the conversion efficiency is slightly lower than that of straight-drawn mono crystalline silicon solar cells.
The four corners of poly crystalline silicon cells are square, and the surface has a pattern similar to that of ice flowers.
