Types of Solar Street Lights

Solar Street Lights are of two types. 

1. Traditional Solar Street Light (also called All-in-two Solar Street Light)

2. All in One Solar Street Lights

The Type of Solar Street Light Image is called All-in-two Solar Street Light

The above Type is called All-in-one Solar Street Light

Components of a Solar Street Light

Solar Panel

Solar panel is the source of power for the solar street light. It collects the solar energy from the sun and converts it into DC power. The power of the solar panel depends on the luminary capacity and the required autonomy days. 

Charge Controller

Charge Controllers regulate the charging and discharging of the battery They regulate the incoming voltage to charge the battery and prevents the deep discharge of the battery. In a solar street light, the circuit to switch on and off the luminary is enclosed along with the charge controller. The charge control is either provided as a separate device or enclosed inside the luminary.  

Battery

Battery stores the power generated by the solar panel. The type of battery used is C 10 Tubular battery. In some cases SMF batteries are also used as they are maintenance free and economical. The all in one street lights use Lithium Ion batteries.In terms of longer life, C 10 rated tubular batteries are the best. 

Pole

The all in one street light can be fitted either on a pole or on a wall. In the traditional solar street, the luminary alone can be fitted either in a pole or a wall. The pole is either MS or GI and is anti corrosive. The pole has provisions to mount the solar panels and the battery. The pole has a luminary mounting arm and solar panel mounting arm.
