Possible Solutions for Solar Lights Not Working at Night

  1. Checking if the Unit Is Turned On

    • It may seem obvious, but sometimes the simplest things can be overlooked. Ensure that the switch on your solar lights is turned on for them to function at night. If the switch is already on and the issue persists, move on to the next tip.
  2. Pulling the Tab on the Battery

    • When you first purchase a solar-powered light, there is usually a pull tab on the battery that needs to be removed for the light to function properly. Check if the tab is still present and pull it out if necessary.
  3. Covering the Solar Panel

    • Solar lights are designed to turn on at night by converting light into energy during the day. If your lights haven't turned on even after it has become dark, it could be due to another light source hitting the solar panel and tricking it into thinking it's still daylight. Try covering the solar panel to see if the lights turn on. If they do, adjust the panel's position to avoid any interference from nearby lights.
  4. Changing the Position of the Solar Panel

    • The positioning of your solar panel plays a crucial role in its ability to absorb sunlight. To ensure optimal performance, position the panel to face south and receive direct sunlight for a minimum of six hours a day. Adjust the angle of the panel, especially during winter months when sunlight is less abundant.
  5. Cleaning the Solar Panel

    • Outdoor solar panels often accumulate dust and dirt, which can hinder their ability to absorb sunlight effectively. Regularly clean the panel using a damp paper towel or a solution of diluted dishwashing liquid and water. Avoid aggressive cleaning that may damage the panel.
  6. Dodging the Shadows

    • Monitor your solar panel throughout the day to ensure that no shadows are obstructing its exposure to sunlight. Shadows can significantly affect the performance of solar lights, especially during the winter months when shadows are longer.
  7. Checking for Water Ingress

    • Water ingress can be a problem for some solar lights, but well-designed lights usually have measures in place to prevent it. If you suspect water ingress, remove any covers and allow all parts to dry thoroughly before reassembling. Consult the manufacturer if the problem persists.
  8. Replacing the Batteries

    • Solar lights typically have rechargeable batteries that eventually lose their charging capacity. If you notice a decrease in runtime or the light failing to turn on at night, it's time to replace the batteries. Good batteries can last one to two years.
  9. Deep Charging the Batteries

    • If none of the previous tips have resolved the issue, try deep charging the batteries. This involves switching off the solar light for 72 to 96 hours while the solar panel continues to absorb sunlight and charge the battery. Deep charging can prolong battery life and improve performance.
  10. Battery Seating or Stripping

    • Incorrect installation of batteries can prevent them from charging properly. Ensure that the batteries are securely fixed and making proper contact with the terminal contacts. Deep charging the batteries may be necessary if the loose battery is causing the problem.
  11. Check for the Presence of Animal Bites

    • Wildlife may occasionally nibble on the wires of solar lights. Inspect the wires and use electrical tape to repair any damage caused by animals.
  12. Tweaking the PIR (Passive Infra-Red) Dials

    • Adjusting the motion detection sensitivity can prevent unnecessary triggering of solar-powered security lights by birds, cats, or other wildlife. Experiment with the sensitivity settings to achieve the desired results.
  13. Using a Mains Charger

    • In some cases, plugging a compatible mains charger into the light or charging the batteries separately may help resolve the issue. Be sure to use a charger specifically designed for solar lights to avoid damaging the circuitry or overcharging the batteries.
  14. Charging the Lights Behind a Glass

    • Placing solar lights behind glass, especially double or triple glazed windows, can impair their ability to absorb sunlight. Position the solar panel outside of any glass obstruction to ensure efficient charging.

When All Else Fails

If you have tried multiple solutions and your solar lights still do not work at night, it's best to contact the manufacturer for assistance. They can provide specialized support and identify any specific issues unique to their brand.

In conclusion, solar lights not working at night can be resolved with simple troubleshooting steps. Regular maintenance and attention to positioning and cleanliness can ensure the optimal performance of your solar lights.
