Photovoltaic panels are divided into P-type and N-type. 

P-type photovoltaic panels use P-type silicon wafers as substrates and diffuse 3-valence elements on the surface to form an N/P-type structure. 

On the other hand, N-type photovoltaic panels use N-type silicon wafers as substrates and diffuse 5-valence elements on the surface to form a P/N-type structure. 

Currently, P-type photovoltaic panels are more mainstream in the market, but there is a gradual shift towards N-type panels because they offer higher power and conversion efficiency. 

Under standard test conditions with an irradiance of 1000W/m2, a cell temperature of 25 degrees Celsius, and AM1.5 spectrum, the current industrial level of N-type solar cells can achieve a maximum module power of over 575W and a conversion efficiency of up to 24.6%. 

P-type solar cells can achieve a maximum module power of over 550W and a conversion efficiency of up to 23.5%. 

A single N-type photovoltaic panel has a power output 25W higher than P-type and an increased conversion efficiency of 1.1%. Do not underestimate these 25W and 1.1%, as every improvement can reduce our BOS (Balance of System) costs. For example, with 40 N-type 575W photovoltaic panels, you can install a 23KW solar power station, while with 40 P-type 550W photovoltaic panels, you can install a 22KW solar power station. The same quantity results in a higher installed capacity. One kilowatt-hour can generate an additional 4-5 units of electricity per day.
