Can a solar street light with a CCTV camera be used in all weather conditions?

Solar street lights with CCTV cameras can work stably in most common weather conditions, but they cannot achieve absolute all - weather trouble - free operation when encountering extreme weather.

Common mild and moderate weather

Sunny days: This is the most favorable working condition. The high-efficiency solar panels (some with a conversion efficiency of over 27% when adopting N-type technology) can efficiently convert solar energy into electrical energy and store it in the lithium iron phosphate battery. At this time, both the LED lighting and the high-definition CCTV camera can operate at full capacity, and functions such as 24 - hour surveillance and real - time transmission of images can be smoothly realized.

Rainy and cloudy days: Most of these integrated devices have excellent water resistance, with waterproof grades usually reaching IP65 or IP66. Their sealed design can prevent rainwater from entering the internal components and causing short circuits.

Moreover, the built-in large-capacity batteries and high-efficiency controllers allow the equipment to rely on the electricity stored in sunny days to maintain lighting and monitoring functions for 3 - 10 days. Even in low - light cloudy environments, the optimized solar panels can still generate electricity to supplement energy.

Normal cold and hot weather: High-quality products are designed with a wide operating temperature range, generally able to work stably between -20℃ and 60℃.

The lithium iron phosphate batteries and all - solid - state batteries used have good low-temperature performance. Although the battery capacity may decrease slightly at low temperatures, it will not affect normal use. In high-temperature environments, the die - casting aluminum shell can effectively dissipate heat and protect the LED lamp beads and camera components from overheating.

Extreme harsh weather

Prolonged extreme rainy and overcast weather: If there are continuous rainy and overcast days beyond the battery's endurance limit (more than 10 days), the solar panel cannot obtain enough light to charge the battery. When the stored electricity is exhausted, the lighting and monitoring functions of the equipment will be forced to stop. However, some AC/DC hybrid models can switch to municipal power supply to avoid this problem.

Extreme high and low temperatures: When the temperature is lower than -25℃ or higher than 60℃, the battery's chemical activity will be severely affected, resulting in a sharp drop in its capacity and even permanent damage. At the same time, the circuit board and other electronic components of the camera and controller may also fail due to the extreme temperature, making the equipment unable to work normally.

Strong storms, sandstorms, and other disasters: In the case of strong storms, the equipment may be blown down or its shell may be damaged if its wind resistance is insufficient. Sandstorms can cover the surface of the solar panel, greatly reducing its light absorption capacity and power generation efficiency. In addition, although the equipment has a certain lightning protection level (generally ≥4000V), it may still suffer from circuit burnout due to lightning strikes in areas with frequent thunderstorms.
