What are the advantages and disadvantages of solar path lights

Update:12 May
Solar path lights are outdoor lighting fixtures that use solar power to charge a battery during the day and then automatically turn on at night. They are a popular and energy-efficient alternative to traditional path lighting that requires electricity from the grid.
Working Principle:
Solar path lights consist of a solar panel, a battery, and an LED light. During the day, the solar panel collects energy from the sun and stores it in the battery. At night, the LED light turns on automatically using the stored energy in the battery. Most solar path lights also have a daylight sensor that prevents the light from turning on during the day when it is not needed.
Energy Efficient: Solar path lights do not require electricity from the grid, making them a highly energy-efficient option. They use renewable energy from the sun to charge the battery, which can then power the light at night.
Easy Installation: Solar path lights are easy to install as they do not require any wiring or electrical connections. They can be placed along walkways, pathways, or garden borders, making them a versatile option for outdoor lighting.
Environmentally Friendly: Solar path lights are environmentally friendly as they do not emit any harmful pollutants or greenhouse gases. They use clean, renewable energy from the sun, making them a sustainable option for outdoor lighting.
Safety: Solar path lights provide added safety to walkways and pathways by illuminating the path, which can prevent trips and falls.
Limited Range: Solar path lights have a limited range of illumination, which can be a disadvantage in larger outdoor spaces. The range can vary depending on the model and can range from a few feet to up to 10 feet.
Sunlight Dependency: Solar path lights rely on sunlight to charge the battery, which can be a disadvantage in areas with limited sunlight. They may not work efficiently in areas with heavy cloud cover, rainy or snowy conditions, or during the winter months when there are fewer hours of daylight.
Initial Cost: Solar path lights can have a higher initial cost compared to traditional path lighting. However, the cost can be offset over time by the savings on electricity bills and the reduced need for maintenance or replacement.
