All in one Solar street light is a kind of solar energy which uses solar energy and converts the absorbed sunlight energy into electric energy, and then stores the electric energy in the battery.

The solar panels supply power to the load during the day and provide lighting for the load at night, thus achieving 24-hour lighting throughout the day.

When the solar panel is illuminated, the stored electrical energy is converted into light energy to drive the light source of the lamp through sunlight, so that the lamp emits bright light.

Solar street lights made by this principle can have a long service life and greatly reduce the cost of use, which is a new energy system with broad prospects and development potential.

solar street light classification and application areas

Solar street light is divided into two types: DC type and AC type.

The former takes solar panel as the power supply, uses battery to store electric energy, and stores the electric energy in the battery, when there is a load needs lighting, then the battery power supply to the lamps.

The latter takes solar panel as the power supply, and uses solar controller to control the working voltage and power size to control the working status of each component in the whole system.

Scope of application: suitable for lighting and road maintenance in parks, roads and other public places.

At present, the domestic municipal street lights and tunnel lights use more DC type, because these lamps and lanterns do not need electricity, the demand for electrical energy is less.

And in some mountainous areas, islands and other places due to the lack of power supply and power points, will use AC type lamps and lanterns.

The structure of lamps and lanterns

The main structure of solar street light consists of light pole, distribution box, bracket, etc.

1, solar modules, generally choose poly crystalline silicon photovoltaic modules (such as BIPV)

2, intelligent controller: is composed of intelligent controller and solar controller, the general choice of STC series.

3、Battery: It adopts maintenance-free lead-acid battery (such as lead-acid battery), generally choosing 12V4AH lead-acid battery or 24V5AH lead-acid battery.

4、Waterproof and dustproof structure: the light pole is installed with a waterproof and dustproof protective cover, good performance against rain and snow, and can effectively avoid the impact of rain and dust on the solar panel and LED light source.

5, distribution box: equipped with a control box; used to control the opening and closing of street lights; mainly composed of LED light source and intelligent control system, according to the need to add a variety of colors of LED light source, LED lights with high brightness, long life and other advantages.

1. Lighting materials

Light pole: aluminum alloy material, surface spraying treatment, high strength, not easy to deformation, impact resistance, corrosion resistance and easy to install, light weight, easy heat dissipation, no rust, can meet the requirements of outdoor use.

Lampshade: tempered glass material, light transmission rate up to 98% or more, high strength, can withstand the strong sunlight.

Battery: the use of colloidal zinc phosphate battery. Safe, environmentally friendly and pollution-free without mercury elements.

Light pole bracket: stainless steel bracket, with high strength corrosion resistance.

Solar panel: imported monocrystalline silicon solar cells (imported crystalline silicon cells from the United States are more cost-effective).

Controller: the use of internationally renowned brands integrated control system.

The choice of light source

Battery as the core component of the solar street light, it is vital to choose the right battery. In order to extend the service life of the solar street light and ensure its good working performance, our battery meets the following conditions.

①Under normal climate, the solar panel generates electricity continuously for at least 4 hours.

②In areas with sufficient sunlight and long duration, the solar panel should have sufficient power generation capacity.

③There is a large enough capacity to store energy (preferably greater than 80%) to ensure that the whole system can be continuously powered.

④When the light intensity exceeds the rated output power of the solar panel (calculated in watts/m2), the battery should have sufficient storage energy.

Storage Battery selection

The Storage battery capacity is proportional to the charging current. When the output voltage is certain, the higher the charging current, the smaller the battery capacity.

In the solar street light system, the capacity of the battery directly affects the power supply capacity and efficiency of the whole system.

Therefore, we need to install the battery in the solar street light system according to the system needs to design the corresponding battery capacity, select the battery in line with GB/T2099.2-20 08 “low-voltage distribution equipment”, GB/T20042-2004 “test methods for electric motors and generators for lighting fixtures” and GB-T10661-1994 “lighting electrical requirements and test methods – general conditions and test methods” standard requirements of the battery.
