How about solar lights?

Solar lights are electric lights that convert solar panels into electricity. During the day, even on cloudy days, they can collect and store solar energy. As a safe and environmentally friendly new electric light, solar lights are becoming more and more popular.

Advantages of solar lights

Energy saving and environmental protection: solar lights use natural light to reduce electricity consumption; solar lights are pollution-free and radiation-free, which conforms to modern green environmental protection concepts.

Safe and durable: At present, the production technology of most solar cell modules is sufficient to ensure that the performance will not decline for more than 10 years, and solar cell modules can generate electricity for 25 years or more.

High-tech content and low maintenance cost: solar lights are controlled by intelligent controllers, which can automatically adjust the brightness of the lights according to the natural brightness of the sky within 1 day and the brightness required by people in various environments. Solar street lights only require periodic inspections and very little maintenance work.

Installation components are modularized and self-powered: flexible and convenient installation, which makes it easy for users to choose and adjust the capacity of solar lights according to their needs.

Disadvantages of solar lights

High cost: The total cost of a solar light is 3 or 4 times that of a conventional light with the same power.

Low energy conversion efficiency: The conversion efficiency of solar photovoltaic cells is about 15% to 19%, and the theoretical conversion efficiency of silicon solar cells can reach 25%.

Affected by geographical and climatic conditions: Since energy is obtained from the sun, the local geographical, climatic and weather conditions directly affect the use of lighting.
