Solar street lamps are used for yard lighting and have advantages such as environmental protection, energy conservation, and intelligence. Here, we will introduce them in detail from the aspects of principle, type, advantages, design points, installation and maintenance:
1. Working principle of solar street lamps
Solar street lamps absorb solar energy through solar panels, convert it into electrical energy, and store it in batteries (such as lithium batteries). At night or when there is insufficient light, the battery supplies power to the LED lamp head to achieve lighting function. The entire process does not require an external power grid and relies on solar energy for self-sufficiency.
II. Common Types of Solar Street Lights in the Yard
Based on the installation method and lighting effect, they can be classified into the following categories:
Type
Feature
Applicable Scenarios
Post-type street lamp
Height usually 3-5 meters, wide lighting range, concentrated light, suitable for large areas of yards or on both sides of main roads
Wide courtyard, driveway, garden path
Courtyard lights
Height 1-3 meters, various shapes (such as European style, new Chinese style), soft light, emphasizing decorative effect and atmosphere creation
Courtyard corner, garden path, porch
Underground lamps
Embedded installation, light spreads upwards or sideways, highlighting the visual hierarchy (such as illuminating sculptures, green plants)
Around lawns, flower beds, water features
Wall lamps
Installed on walls or columns, saving space, providing local lighting (such as illuminating gateways, fences)
Courtyard wall, exterior wall of the house, garage entrance
III. Core Advantages of Solar Street Lights
Energy conservation and environmental protection
No electricity bills. Once installed, it provides long-term benefits and reduces carbon emissions, aligning with the concept of green living.
The lifespan of the solar panel can reach 10-20 years. The energy consumption of the LED lights is only 1/10 of that of traditional incandescent lamps.
Intelligent and convenient
Built-in light control sensors automatically sense the intensity of light. Lights turn on when it gets dark and turn off when it gets light. No manual operation required.
Some high-end products support time control functions (such as setting lighting from 6 p.m. to 1 a.m. at night) or remote APP control.
Flexible installation
No need to pre-bury cables. Simply fix it directly to the ground or wall, suitable for courtyard renovations or areas without power grids (such as rural and suburban areas).
Safe and durable
Low-voltage direct current power supply (usually 12V/24V), avoiding the risk of electric shock, especially suitable for families with children or pets.
The lamp body uses waterproof and rust-proof materials (such as aluminum alloy, ABS engineering plastic), adaptable to outdoor environments such as rain, snow, and high temperatures.
IV. Design Key Points of Solar Street Lights in the Yard
Lighting demand planning
Brightness calculation: Select an appropriate wattage based on the yard area (e.g., 5-10W LED lights for 10㎡ yards, 15-20W for over 30㎡).
Lighting duration: In northern winters, the sunlight is short. It is recommended to choose energy storage-type batteries (such as 12Ah lithium batteries) to ensure normal lighting for 2-3 consecutive cloudy days.
Layout and landscape integration
Path lighting: Install one pole-type street lamp or courtyard lamp every 3-5 meters along the path to avoid glare affecting walking.
Focus lighting: Use buried lights to highlight trees, fountains, or sculptures in the courtyard to create a sense of night-time landscape hierarchy.
Style uniformity: The lamp design should match the style of the courtyard decoration (such as antique copper-colored lantern style for Chinese courtyards, simple line style for modern courtyards).
Battery and installation angle
The solar panel should be installed facing south, with an inclination angle close to the local latitude (such as about 40° in Beijing). This ensures the best light collection efficiency.
The battery is recommended to be buried or installed at the base of the lamp pole, with proper waterproof and anti-theft measures.
Solar street lamps, through reasonable design and selection, not only can meet the lighting needs of the courtyard, but also can become a part of the courtyard landscape, achieving the dual value of functionality and aesthetics. If you need specific model recommendations or customized solutions, please provide further information such as the size and style of the courtyard! Please contact us.
