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: Half cell solar panel uses high efficient perc poly 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.
