The solar landscape lamp is used for outdoor lighting, and it often encounters bad weather such as low temperature or rainy, low temperature, rainy and snowy weather. The solar street lamp controller is usually installed in the lamp pole, which easily forms the sign of short circuit from water to the controller. When calculating the solar street lamp equipment, the local rainy climate should be considered to ensure that the solar street lamp can still be used normally. It is necessary to ensure that solar street lamps can still be used for normal lighting in rainy days.

Every day lighting time, is every night lighting a few hours. The longer the lighting time is, the more power is consumed, and the larger the equipment of solar panel and battery is. If there are more trees and houses around, the solar panel will be blocked at some time every day, so the equipment will be increased.

The local temperature throughout the year, which mainly affects the discharge condition and service life of solar street lamp storage battery. The colder the climate, the less the battery discharge. For example, the battery in Northeast China should be equipped with a larger one, so as to ensure the service life of solar street lamps. The normal northern winter battery discharge can only reach 70% of the summer. If the battery is used with a long-term power loss, its life will be shortened a lot. The pole of solar street lamp is planned to be several meters. The higher the pole of the solar street lamp is, the farther the light source is from the ground, so the higher the brightness requirement for the light source is, the more power consumption will be due to the high brightness, so the overall equipment of the street lamp will be increased.

The ultraviolet intensity of the sun in the area where the solar street lamp is used is several hours of sunshine every day. It is the effective lighting time every day, which is directly related to how long the solar panel can charge the battery every day.
