First, high temperature may enhance the efficiency of solar panels. Generally speaking, as the temperature rises, the intensity of solar radiation will also increase, which will improve the efficiency of solar energy conversion and extend the lighting time. However, it is important to note that extreme high temperatures may lead to a decrease in battery efficiency, as excessive temperatures can increase the internal temperature of the battery, accelerating its aging process and thus reducing its capacity.
Secondly, high temperatures may also have an impact on the energy storage capacity of lithium batteries, reducing the actual capacity, which in turn may affect the lighting time and stability.
