typically to provide a smaller community with electricity.

2. What is the lifespan of solar panel?
High-quality solar panels used in Mutian product lines are typically rated at
80% of the minimum power output rating at 25 years.

3. What's the main difference between mono and polycrystalline solar panel?
Production and cost.
Polysilicon technology is more mature since it is an early technology compared with Monosilicon.


4. Does your controller has the dual time control function?
Our solar charge controller is designed with dual time control function.
You can set up the lighting time and divide it into two parts, like 10 hours
(6H full power mode + 4H half dimming mode)
