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.

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.
Before each loading and shipment, our factory has special personnel to check the QC inspection of qualified products.
They distinguish and mark the area to place, and ensure the shipment quantity, model, and customer name is accurate, only after the standard is allowed to load containers.
Ensure that you receive complete and correct goods at the end.

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.
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.
Our broadcast station is located at the top of the mountain, and we have used diesel generators before. We worry about the diesel transportation of the generators, maintenance, and voltage instability every day.
The current power source is the 30kw hybrid solar wind energy system. In our limited budget and installation area, PVMARS recommends using a solar wind system. This can reduce the battery footprint, but also provide a 24-hour uninterrupted and stable power supply.
It’s awesome how much I save on my partner’s bill with 10kw solar and battery package, but for me, it’s the peace of mind that I can use our electrical appliances knowing that we have clean energy. I’ve already recommended them to family members because they’ve been friendly, upfront, and responsive.
500kw solar energy storage system has operated in our remote countryside for two years. This week, Dunsborough experienced another blackout. Now we are happy to tell you that our town is not affected. All houses keep the lights on, use refrigerators, surf the Internet and listen to music to relax. This is thanks to PVMARS solar company, which customized the solar battery system according to our town’s electricity demand. This has greatly improved our local residents’ happiness index.
There was no problem with the installation, the instructions and online remote video install guidance were great, the system is working great and I’m producing 90% of my power. I just got my first bill back, last year $1290, this year $119, it’ll pay for itself in two years at this rate. You just have to adjust your times for power usage and you’ll save a lot.
The 5kw solar storage system was installed in 2018. We were initially attracted to the idea of using lithium batteries at night while solar power supply our house during the day. In addition, it can also provide seamless grid failure protection. At that time we did not know that the main city power had been cut off, until we saw outside, originally brightly lit streets and houses, because there is no electricity change to dark, to realize that the city grid has been cut off. And our house because of solar energy, to achieve power independence, electricity freedom.
We have seen an immediate reduction in our energy bills and a change in our power consumption patterns since we installed the PVMARS off-grid solar power system. And PVMARS IOT is so smart to remind me why my battery is running so fast. We can also contribute power back to the grid over the summer, which is a big plus.
