If there are no external factors (such as natural disasters, fire and explosion, lightning), the solar panel system can operate up to 30 years. In particular, the inverter system can operate up to 10 years before needing to be replaced. Therefore, with the current electricity price, the investment in a solar power system has the following payback period:

+ For manufacturing enterprises: about 5 years.

+ For commercial enterprises: about 4 years.

+ For family: about 5 years.

Condition:
