How do photovoltaic solar lights charge? How long does it take to fully charge a solar light?

Solway will tell you the factors that affect the illumination duration of solar street lights

The time required to charge a solar street light is affected by many factors. The solar street light battery receives solar energy through solar panels and converts it into electrical energy for storage. The photovoltaic panels convert solar energy into electrical energy to illuminate. The longer the charging time, the more electrical energy the battery stores, and the greater the lighting effect and radiation range of the solar street light.

Check out this APS solar street light from Solway. The back panel is a silicon solar panel, and a solar panel is added on the top to increase the charging speed.

Solway solar panels are energy-saving and environmentally friendly. They do not require wires and can be installed anywhere. They are very safe. Therefore, they can be charged in 5-7 hours of sunshine on a sunny day and discharged for 8-10 hours at night. Solway's high efficiency directly affects the charging time. The larger the solar panel, the longer the charging time.

At present, the factor that affects the charging time of solar street lights is the battery capacity. Solway's ASP series uses a new generation of a grade lifePO4 battery, which can shorten the charging time.

Solar panel angle and orientation

The angle and orientation of a solar panel can significantly affect its ability to capture sunlight. Solar panels tilted toward the sun will receive more direct sunlight, resulting in shorter charging times. Correct installation

Average Charging Time

On average, solar street lights can be fully charged in 6 to 8 hours under direct sunlight. However, this can vary depending on the factors mentioned above. Here is a breakdown of typical charging times based on battery capacity:

12V 7Ah battery: approximately 6-8 hours

12V 20Ah battery: approximately 8-10 hours

12V 40Ah battery: approximately 10-12 hours

Nighttime Operation and Battery Discharge

Operation Period

Once fully charged, solar street lights can operate all night long.

To sum up, what Solway wants to tell you is that the charging hours have nothing to do with the radiation range. It mainly depends on the specific power, luminous efficiency, battery capacity, etc. of your lamp as well as the design of the lamp.
