Characteristics
Half-cut Cells Advantages
(1)Reduced power losses
The solar cell is divided into two, 75% less electrical losses, increased overall current output of 2-4%. Make make the output power 5w-10w more than normal solar panel.
(2)Increased partial shading tolerance
When a solar panel is partially shaded, there are still 50% space can generate power. But for tranditional solar panel, its 100% no power output.
(3)Reduced hot spots and temperature
Half-cut solar cells reduce the current per substring, this technology can reduce the peak temperature of hot spots by up to 20ºC.
PERC Technology
PERC stands for Passivated Emitter and Rear Cell. It improves efficiency by allowing electrons to flow more freely and also by increasing the reflectiveness of the back of solar cells. Increase solar panel efficiency.

Let's Say No To Expensive Electricity Bills!
Research has proved that most countries in the world have problems of insufficient power supply and high electricity bills, which make people's quality of life unable to improve.
InkPV solar system uses advanced technology to solve these problems through a professional team.
Our system has strong advantages. Our system can fully charge a backup battery in 5 hours via solar panels. Reduce the cost of home energy use and let your home solar system make your life better and more comfortable.
According to the user's Home construction and electrical equipment power consumption design plan, to provide customers with customized solar energy storage system solutions.
Our solar energy system adjusts the daily charging and discharging conditions through intelligent algorithms, charging and storing energy during the low-peak period of electricity consumption, and discharging during the peak period of electricity consumption.
How do I choose a off-grid system?
