Reposition lights for the best sun angle throughout the day. In winter, consider moving them further south or installing adjustable panels
Extend Sun Exposure
Aim for 8-10 hours of direct sunlight for optimal charging. Consider leaving lights switched off during the day to conserve battery for nighttime
Harness Indirect Light
Even on cloudy days, place lights near windows or reflective surfaces for some additional charge. South-facing windows offer the best access to diffused sunlight.
Embrace Artificial Light (as a last resort)
While not as efficient as sunlight, a strong incandescent bulb (60W+) placed directly above the panel can offer a temporary charging boost
Clean the Panels Regularly
Accumulated dust, grime, and even fingerprints can significantly reduce charging efficiency. Use a soft, damp cloth for gentle cleaning.
Turn Off Lights During Day
Switching off solar lights during the day helps conserve the battery's stored energy for longer illumination at night.
Reduce Light Duration
Consider adjusting the light duration settings on your solar lights if available.
Upgrade Bulbs (consideration)
If your lights use inefficient incandescent bulbs, upgrading to LED bulbs can significantly improve their brightness and battery life, even in winter.
Temporary Indoor Boost
For lightweight lights, bringing them indoors to a sunny windowsill or near an incandescent bulb can provide a temporary charge boost.
Seasonal Storage (optional)
In harsh winter locations, consider storing your solar lights indoors during periods of heavy snowfall or prolonged cloud cover.
