Ans: Solar lights need direct sunlight. The more sunlight received during each day, the longer the light will operate that night. Since solar lights are powered entirely by the sunlight they receive each day, operating times will vary by specific location, daily weather conditions, and season. Many of our solar lights can run for up to 8-10 hours. As a general rule, solar lighting performs better during the summer months mainly because the longer and sunnier days enable a full charge to be achieved. Adverse weather and short winter days do affect performance, as charge times are reduced in relation to hours of daylight and the strength of the light.
