company news about How to choose the type of solar energy system

On-grid system: Firstly the solar panels finish the conversion of energy from sunlight into electricity; then the on-grid inverter change the DC to AC and supply to the electricity appliance. On-grid system have no need battery and it tied to the utility grid, so will need to apply a smart meter first. This system can help to reduce the electricity cost and also can sell the electricity to the utility grid, if your government have policy to encourage the private sell electricity to the utility grid, this type of system will be perfect.

Off-grid system: Firstly, the solar panels finish the conversion of energy from sunlight into electricity; Secondly, the combiner box finish the combination of the electric current from solar panels; Thirdly, the controller will control the battery’s charge and discharge; Fourth, the off-grid inverter change the DC to AC, then supply to the electricity appliance. Off-grid system need the battery as the backup, generally it used in places where have no utility grid, like the island. It also can use a generator as the backup.

Hybrid system: Firstly, the solar panels finish the conversion of energy from sunlight into electricity; Secondly, the combiner box finish the combination of the electric current from solar panels; Thirdly, the battery store electricity or working through charge and discharge; Fourth, the hybrid inverter change the DC to AC, then supply to the electricity appliance. Hybrid system is the combination of Off-grid and On-grid, with both system’s advantages and it also cost more. If your place have the utility grid, but frequently power off, choose this system will help you lower the electricity bill and also can sell the electricity to the utility grid.

During March Expo 2020, if the amount is more than $5000, you could get the coupon $100. If the amount is more than $30,000, we will present an umbrella with lithium battery and thin film solar panel.
