P-types VS N types Solar Panel

Photovoltaic cells can be classified into P-type cells and N-type cells based on substrate materials

At present, P-type is the mainstream photovoltaic cell, with a market share of more than 85%, and P-type is divided into two types, BSF cells and PERC cells.

The former is the absolute mainstream before 2020, and the latter is the absolute mainstream at present.

The time when the roles of the two changed is 2016.

It is also during this process that the conversion of energy has increased from less than 20% to 23%.

N-type solar cells are divided into three types: TOPCon, HJT, and IBC, and their energy conversion efficiency is about 25.5%.

It is about 2% higher than P-type photovoltaic cells.

According to authoritative forecasts, by 2030, the market share of N-type photovoltaic cells will reach about 56%.

Although there are three types of N-type solar cells, only TOPCon and HJT are currently commercially popularized and applied.

Currently, TOPCon has a higher penetration rate.

P-types VS N types Solar Panel

TOPCon types solar panel have the following characteristics:

1- High efficiency: TOPCon N-type can reach 26.8%, the efficiency of PERC is about 23.5%, and the efficiency difference can reach 3.3%.

2- Low attenuation: The TOPCon solar panel does not drop gears, while the current test efficiency of the PERC solar panel drops 1 to 2 gears after a period of retesting.
On the other hand, for the overall solar panel, there is no attenuation in the power generation of TOPCon – it can last for 30 years with an effective 100% performance power output, while PERC has a power attenuation of nearly 8% in the first year.

3- Good long-wave response: PERC only responds well to short-wave, while TOPCon responds well to both long-wave and short-wave.
TOPCon is not affected by the weather, and the power generation is guaranteed continuously, while the power generation of PERC is seriously affected by the weather.

Solar Products FAQ

Q: What does this PVMARS system include?

A: A complete off-grid or on-grid solar clean energy system, including all accessories required for installation.

Q: Can I customize one?

A: Of course, you can customize the most efficient solar power system. Your exclusive solar expert is waiting. To provide you with any energy solution, customized according to different power consumption, actual use of equipment, scenarios etc. Solar systems come in different configurations.

Q: Who is responsible for transportation? Or home delivery?

A: There will be dedicated staff responsible for your products’ production, packaging and shipping. To deliver goods safely to the destination port by sea or air. The entire process, including transportation and customs clearance, is handled by us. Europe, Asia, Africa to provide home delivery or nearby pickup service. Provide relevant packing and shipping documents and information on time.

Q: What is the lifetime of a solar power system?

A: The life of the solar panel is 25 years, the charger controller is 5-7 years, the inverter is 5-7 years, and the battery is 8-10 years. Our IOT monitors the installation and operation of your solar power system in real time to extend service life.

Q: Are there any protection measures for solar power overload, and how do electricity leaks, lightning strikes, and hail happen?

A: PVMARS Solar’s PV combiner box and inverter have overload safety functions. To protect each other, they will disconnect the connection with your equipment in the event of abnormal voltage, such as lightning strikes and leaks. After the voltage is restored automatically, the solar system will start automatically. Secondly, the photovoltaic module floor is made of excellent impact-resistant tempered glass. This glass can withstand 200Pa wind stress and 7200Pa snow stress after strict trial and test when passing EU certification.

Q: What can you expect from PVMARS Solar?

A: In addition to providing products, PVMARS solar also provides free on-site survey, customized design solutions, production, installation and maintenance one-stop services.
