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.

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.

Q: How to calculate capacity for the inverter?
A: If you have a 1set 9000BTU air condtioner, we suggest to use 5kw inverter.
Because for the appliance like pump and air conditioner, there are motor inside, the start current is 4-6time than rate current. 
Or make it simple, for 3 bedroom house, most family will choose a 10kw inverter for their off grid system.
Q: Can an inverter store power?
A: The inverter can store power to the battery via grid.
Because there are AC input in our inverter, that means the battery can be charged by the inverter. To put the AC power to DC power.
Q: Can off grid solar system work without batteries?
A: Can. Check our batteryless solar system, max is 7kw solar home system.

Types of system

Off-grid solar system

Off-grid system is suitable for areas without grid-connected or unstable grid-connected power, composed of solar panels, connector, inverter, battery and mounting system.

On-grid solar system

On-grid solar power system connects to the power grid, can sell excess electricity to the public grid.

Hybrid solar system

Hybrid Solar System combines advantages of on grid solar system and off grid solar system.
It connects to grid, you can sell solar power to grid or use directly.
If grid stop, battery supply power.

Solar and wind system

If your place enjoy good wind speed, the wind turbine can be a very good power source. It can give you unstopable power 24hrs. With solar and wind power, your home can be 100% off-grid.
