The shelf life of solar lights is generally 3-5 years, depending on the use environment and quality. If the solar panel is of good quality and the use environment is good, the life of the solar light is relatively long. In addition, the life of household solar lights is between 5 and 10 years, depending on the product type and quality. For example, high-power floodlights and column lights can be used for 5-10 years, while small decorative light strings have a shorter life of about 1-2 years.

Factors affecting the life of solar lights

Battery quality: The quality of the battery directly determines the life of the light. Lithium batteries have a longer life, but high-quality products need to be selected.

Solar panel size: The size of the solar panel affects the charging efficiency, which in turn affects the life of the light.

LED light source: The LED light source has a longer life and can generally be used for more than 50,000 hours.

Controller and light pole: The quality of these components will also affect the overall life of the solar light.

Ways to extend the life of solar lights

Daily maintenance and care: Clean the solar panel and wire interface regularly to avoid dust and dirt accumulation that affects the power generation effect.

‌Pay attention to the use environment‌: Place the solar light in a sunny and well-ventilated place to avoid long-term exposure to humidity‌.
