9BB 144 half cells mono solar panels 420w430w440w450w all good quality class A for on-grid or off-grid solar power system for residential or commercial usage.

Application
AMSO SOLAR mono half cells series solar panel is our leader in terms of efficiency. It combines PERC with half cell technology. Hereby, this module reaches cutting-the-edge efficiency values, which makes it the high performer in our portfolio.

Amso Solar Top-class Warranty for Solar Panels:

1: First year 97%-97.5% power output.

2: Ten years 90% power output.

3: 25 years 80.2%-80.7% power output.

4: 12 years product warranty.

* Standard test conditions:measured values(atmosphiric mass AM.5, irradiance 1000W/m2, battery temperature 25℃)

Benefits:
1: This type of half cell solar panels use 9 bus bars high efficient 166mm solar cells, and with 144 half cells that are cutted by 72 full size cells.
2: Advanced half cell technique improves the power of solar panels to around 5-10w.
3: With the improvement in output efficiency, the installation area decreases by 3%, and the installation cost decreases by 6%.
4: Half cell technique minimizes the risks of the cells’ crack and the damage of bus bars, therefore increases the stability and reliability of solar array.
5: It helps reduce the heat of solar panel by 1.6, this is because of the deduction in the instinct current and potential loss which leads to the operating temperature cool down.
