As is well known, the working principle of solar street lights is mainly to receive solar energy during the day, convert it into electrical energy and store it in a battery, and then use the battery to provide power for lighting at night. But if there is no sun on rainy days, can't solar street lights work? I believe many people have had this doubt before. If solar energy cannot work on rainy days, it will be very inconvenient. However, what the editor wants to tell you is that the working condition of many solar street lights can be set to be affected by rainy days.
Whether solar street lights can work on rainy days mainly depends on the setting parameters of "rainy days". The number of rainy days refers to the number of days during which solar street lights can provide normal illumination in continuous cloudy or rainy weather. Once this value is exceeded, the solar street lights will no longer function properly. In general, manufacturers default to three days of rainy and cloudy weather, but if you have higher demand when purchasing, there are also solar street lights with a default duration of five to seven days.
When it is cloudy and rainy, although solar street lights cannot actively receive solar energy, the stored electricity can maintain normal operation for a period of time. After a sunny day, solar street lights can receive and store electricity while preparing for the next rainy day, so solar street lights can work on cloudy and rainy days.
However, no matter what brand of solar street lights, they cannot work normally under long-term rainy and cloudy conditions, so this ability has limitations. Don't misunderstand. In addition, if the damage is caused by the solar street lamp itself, it is necessary to replace the solar street lamp. Unqualified solar street lamps are easily affected by rainy weather. Therefore, when choosing, please choose a solar street lamp with proper treatment and guarantee. In addition, the editor would like to remind everyone that when choosing solar street lamps, it is necessary to consider their living conditions.
