Solar courtyard lights come in various styles, and when choosing them, it is important to consider the architectural style of the community and the lighting environment. However, many people in northern regions have questions about whether solar courtyard lights can be used during heavy snowfall. To address this concern, we will explore this issue.
In heavy snowfall, the environmental temperature can drop to several degrees or even tens of degrees below zero. Does extreme weather affect the use of solar courtyard lights?
First, let’s understand the type of batteries used in solar courtyard lights. Most solar light products on the market primarily use lithium batteries, which are categorized into ternary lithium batteries and lithium iron phosphate batteries. These two types of batteries have different discharge curves based on their usage environment, meaning their characteristics vary. In the southern regions, summer temperatures can reach around 40°C, while in the northern winters, temperatures can drop below -10°C, or even lower.
Taking 25°C as a baseline, the discharge capacity of both types of batteries at high temperatures of 55°C and at normal room temperature (25°C) shows little difference. However, at -20°C, there is a significant difference between ternary lithium batteries and lithium iron phosphate batteries. The capacity of both types will decrease correspondingly, resulting in reduced discharge efficiency.
Therefore, when selecting solar courtyard lights, it is crucial to consider the operating environment to avoid impacting the charging and discharging efficiency of the lights. In simpler terms, this will affect the proper discharge depth of the battery. As a result, the duration of the light may be affected, and users may notice variations in lighting time with changes in weather.
This concludes our discussion on the impact of heavy snowfall on solar courtyard lights. Additionally, it’s important to know that solar courtyard lights have a microwave sensing function, which can be set to sensing mode. This feature can effectively address issues during low temperatures in winter or rainy seasons.
