Panel Size: 200–400W panels (higher watts = more energy).
Sunlight Hours: Lights in sunny areas (6+ hours/day) generate more.
Efficiency: Monocrystalline panels convert ~20–22% of sunlight to electricity.

Composition & Structure Of Street Solar Light

Street solar light contains the light head, bracket and outdoor lamp pole. The bracket of the solar energy street lights is the most important thing in design, showcasing its style and seamlessly integrating all other components perfectly.

The light head is the housing for the light source and sometimes contains optical and electrical components such as reflectors, transmissions, and ballasts. The design needs to consider whether the dimensions are sufficient to accommodate these components and should ensure that it is robust, dissipates heat effectively, and prevents damage from the external environment.

When designing the solar street outdoor lamp pole, the following elements should be considered:

① The lamp pole should have sufficient load-bearing capacity and wind resistance. Due to the large size and heavy weight of the solar panel, the center of gravity after installation should be as close as possible to the position of the bracket outdoor lamp pole, to ensure the sturdiness of the structure.

② Give full consideration to the orientation of the road and the surrounding buildings and trees to determine the installation location of the solar street light antiblackout to ensure that it can receive sufficient light.

③Lamp pole's height design needs to consider the road demand, according to the light source height requirements, to determine the height of the outdoor lamp pole.

④ Lamp body materials should be durable and aesthetically pleasing.

How To Choose The Solar Panel and LED Lighting Source?

The main components of street solar light are the solar panel, LiFe PO4 battery, BOSUN^® patented Pro-Double MPPT solar charge controller, light bracket and LED lighting source. The price depends for sure, and the solar generation system affects the performance and price the most. Solar batteries are separated into 3 types:

Silicon crystal solar battery, the most widely used type of battery, monocrystalline cells are black in appearance and have efficiencies of 16% to 20%. Polycrystalline solar battery are blue in appearance and have efficiencies of 16% to 17%, it's less costly than the monocrystalline. N-type bifacial battery power generation performance evaluation of up to 25.6%, is still in the research and experimentation stage, and has not been widely promoted widely.
Thin-film solar battery, including amorphous silicon, cadmium telluride, copper indium gallium selenide, have the characteristics of lightness, flexibility and thinness, are easy to shape, have a good low-light effect, and can still generate electricity in a cloud-shaded sun or indoor environment, but the overall efficiency is low and the cost-effectiveness is not high.
Emerging solar battery, such as organic solar cells.

In the rich sunlight source area, it is more suitable to use monocrystalline solar batteries. This type of battery has simple craftsmanship, lower price, and high efficiency of sunlight-electricity conversion. It's been popular in the street solar lighting field.

The main light sources on the market today are incandescent lamps, tungsten halogen lamps, fluorescent lamps, neon lamps and LED lamps. In general, ceramic metal halide lamps, compact fluorescent lamps, induction lamps and LED lamps have higher light efficiency and are more suitable for use in solar street lights.

How To Choose The Solar Battery and Solar Charge Controller?

Considering various aspects, lifespan, electricity storage capacity, volumetric, price and environment are the most considerable factors. The batteries commonly used in solar powered street lights are mainly lead-acid and nickel-cadmium batteries. Lead-acid batteries have stable performance, easy-to-obtain, and inexpensive materials, but they are larger, heavier, and costly to use, and are suitable for use in areas with abundant solar energy resources. Nickel-cadmium batteries are lightweight, long-lasting, recyclable, and effective in low-temperature environments.

The control of street solar light can be controlled by an intelligent charge/discharge solar charge controller. Check on the smart street lighting and our patented Pro-Double MPPT solar charge controller.

Road Environment Requirements For Solar Energy Street Lights Design

Conventional Street Layout Of lighting fixtures

According to the different forms of road lighting, the effective width of the road surface, and the installation type of solar powered street lights can determine the height and installation spacing. It should be noted that the height of the lamp refers to the height of the light source, not the absolute height of the street lamp as a whole.

Design of Motorway Street Solar Lights

The goal is to provide drivers with clear road guidance and ensure that they can quickly determine road conditions at night, thus enhancing driving safety and comfort. The lighting brightness of such roads must be higher than that of ordinary roads, and high-brightness, high-efficiency light sources need to be used.

Walkway street solar light design

Walkway street solar lights mainly serve pedestrians and are commonly found in neighborhoods, parks, schools, pedestrian streets, and courtyards. Street light design and color temperature selection of light source are usually based on the use of the scene and demand.

Here's a step-by-step guide to installing a solar LED street light for residential, commercial, or municipal use

Plan and Prepare

Location: Ensure the solar panel receives 6–8 hours of direct sunlight daily (avoid shaded areas).
Power Needs: Calculate the required brightness (e.g., 100–200W per light) based on the area size (e.g., parking lot vs. garden path).
Local Regulations: Check zoning laws, permits, or wiring codes (if connecting to existing systems).

Assemble the Components

Step 1: Install the Solar Panel

Mount the panel on the pole or a nearby wall/rack (ideally elevated for better sun access).
Angle the panel to face the sun’s peak direction (south in the Northern Hemisphere, north in the Southern).

Step 2: Set Up the Pole

Dig a hole 1.5x the pole’s diameter and 2–3 feet deep.
Secure the pole with concrete for stability (critical for windy areas).

Step 3: Place the Battery

Bury the battery in a waterproof, ventilated box (6–12 inches underground) near the pole, or mount it on the pole.

Wire the System

Safety First: Turn off all power sources (even solar systems can have residual charge).

Connect the solar panel to the charge controller (regulates energy flow).
Link the controller to the battery (ensure correct polarity: + to +, – to –).
Wire the LED light fixture to the controller.
Pro Tip: Use UV-resistant cables and waterproof connectors to prevent corrosion.
