3 principles of PV product design

　　The essence of energy is cost, and technology is the decisive force driving cost down. Since 2020, the wave of expansion with 210-size large silicon wafers as the leading force has been frantically unfolding.

　　210 size, 600W+ has become a new benchmark in the PV industry. Why are the size and power of PV panels getting larger and larger? The specific reasons are:

　　A: Simple

　　Improve quality, function, and reliability by simplifying steps, simplifying problems, and reducing materials. This is the most important principle for PV product design and an important reference for choosing a technical route.

　　It is easy for us to see the nature and trend of technological progress through this principle. For example, the essence of double glass components is to remove the backplane and put the battery inside the glass. This is to reduce the attenuation and improve the reliability by reducing the material.

　　B: Altruism

　　Product design should be based on the industry ecology, especially the partnership with suppliers. Excellent product design is not only the key to providing customers with value, but also the guarantee for suppliers' confidence. Therefore, product design must be considered from the perspective of the entire industrial ecology. The principle of "altruism" can also reduce the difficulty of value realization for partners.

　　The 210-size product can be quickly introduced into the market, the main reason is that suppliers in all aspects of crystal pull, silicon wafer, battery, module, power station, and equipment can benefit from it.

　　C: Core competitiveness

　　The key to the growth of any technology-based company is to build the core competitiveness of its products, that is, to expand differentiated advantages and build core technical barriers.

　　During the period when the PV industry developed by leaps and bounds, technological innovation was more intensive, and specialized division of labor was also more pronounced. Enterprises in the industrial ecology have their own strengths. In the future, the PV industry will not only have industry leaders such as TSMC focusing on technology and manufacturing, but also equipment giants such as AMAT.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, PV energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
