Solar Cell Type Comparison

Solar cells are the core component of solar panels, so choosing which solar panels to use is critical. The following is a brief introduction and comparison of several different types of solar cells. 

1) Crystalline Silicion Solar Cell (Mono vs. Poly)
Mono solar cell's efficiency & price higher than poly 

Crystalline silicon solar cells are currently the most common solar cell on the market. It is divided into monocrystalline silicon solar cells and polycrystalline silicon solar cells. At present, the efficiency of monocrystalline silicon solar cells is about 19% - 21%, and the efficiency of polycrystalline silicon solar cells is about 17% - 19%. Therefore, the efficiency of monocrystalline is higher than that of polycrystalline, of course, the price of monocrystalline solar cells is also higher than that of polycrystalline ones.

However, as the technology of monocrystalline silicon solar cells is further improved and the production cost is further reduced, the price difference between monocrystalline solar panels and polycrystalline solar panels is not too large for small solar panels. Therefore, if the solar application product has a limited use area, it is better to select a monocrystalline solar panel. 

For crystalline silicon solar panels, the encapsulation method can be glass lamination, PET lamination, or epoxy. 

2) Sunpower Solar Cell vs Crystalline Silicon
Sunpower solar cell's efficiency and price is the highest.

Sunpower solar cells are a high-efficiency solar cell produced by Sunpower Corporation of the United States. It is currently the most efficient solar cell on the market with an efficiency of over 21%. Of course, its price is also much more expensive than crystalline silicon solar cells.

For Sunpower solar panels, the encapsulation method can be PET lamination, or ETFE lamination.
