The wattage of solar panels needed for a solar street light depends on factors such as the power of the fixture, the intensity of sunlight in the geographical location, and the duration of use. Generally, each solar street light is equipped with 1-2 solar panels, which can meet the lighting needs at night.

• Energy efficiency: LED street lights are more efficient and consume less energy than traditional high-pressure sodium or incandescent lamps, and they have a longer lifespan.
• Environmental protection: LED street lights do not contain harmful substances such as mercury and can reduce carbon emissions.
• Lifespan: The average life of LED street lights is over 50,000 hours, which is much longer than traditional street lights.
• Lighting quality: LED street lights provide higher lumen output, more uniform brightness, and less light pollution.

• Energy saving and environmental protection: Powered by solar energy, avoiding electricity costs.
• Maintenance-free: No need to connect to the power grid, reducing the hassle of line maintenance.
• Automation: Automatically recharges during the day and lights up at night, with intelligent control.
• Adaptability: Can be used in various outdoor environments, such as parks, courtyards, squares, etc.

• Building exterior lighting: Can highlight the appearance of buildings by projecting light.
• Squares, scenic areas, stadium lighting: Used to provide large-area, strong lighting.
• Billboard lighting: Provides clear visual effects for advertising signs.
• Garden lighting: Highlights the beauty and safety of landscapes.
• Security lighting: Helps increase nighttime security to prevent theft and intrusion.

The maintenance of solar street lights is relatively simple but also requires regular inspection and maintenance:

• Clean the solar panels: Regularly clean the panels to remove dust and dirt, ensuring effective absorption of sunlight.
• Check the battery status: Regularly check if the battery is working properly and replace it if necessary.
• Inspect the fixtures and poles: Check if the LED lights are on and if the poles are intact, ensuring safety and stability.
• Check the connection wires: Ensure there are no damages or looseness between the battery and the fixtures.

• Power source: LED floodlights generally use grid power and need to be connected to the power grid; solar floodlights rely on solar panels and batteries for power supply and do not need to be connected to the grid.
• Installation location: Solar floodlights are suitable for places without power supply, while LED floodlights are typically used in places with an existing power grid.
• Environmental friendliness: Solar floodlights are more environmentally friendly, using renewable energy and reducing electricity consumption.

The choice between solar street lights and LED street lights depends on specific usage needs:

• Solar street lights are suitable for areas without power grid coverage, especially in remote areas, streets, parks, etc.
• LED street lights are suitable for urban areas and regions with power grid coverage, as they offer good lighting effects, low maintenance costs, and a long lifespan.

The choice of LED floodlight power needs to consider the illuminated area and required brightness. Generally:

Small areas such as courtyards and gardens can choose LED floodlights with a power of 20W-100W;

Medium areas such as parking lots and road lighting can choose 100W-300W;

Large areas such as squares and building exterior lighting can choose LED floodlights with 500W or higher power.

The installation cost of solar street lights depends on several factors, including the type of fixture, the number of installations, geographical location, and whether additional infrastructure is needed (such as poles, installation locations for solar panels, etc.). Typically, the installation cost for each solar street light is between $150-$500, but it may vary depending on specific requirements.
