Garden light solar cell life:
1. Analysis of the life of core components
Solar panels
Lamination packaging: using high-efficiency packaging technology, the life can reach more than 25 years, suitable for long-term outdoor use.
Epoxy packaging: the process is simple but easy to age, the life is only 1-2 years, and it is only suitable for short-term or low-cost scenarios.
Battery
Lead-acid battery: conventional life is 5-8 years, low cost but high maintenance requirements, suitable for scenarios with limited budget.
Lithium battery: life is 5-10 years, high energy density, good cycle performance, recommended for garden lights with high endurance requirements.
Colloid battery: life is 6-8 years, good stability, but weak low temperature performance.
LED light source
Qualified quality LED light source has a life of up to 50,000 hours (about 10 years), low power consumption and high brightness, and is the mainstream choice for garden lights.
2. Key factors affecting lifespan
Packaging process
Laminated packaging is UV-resistant and weather-resistant, with stable long-term performance; epoxy packaging is susceptible to moisture and cracking, and its lifespan is limited.
Battery matching and maintenance
The battery capacity needs to match the LED power to avoid overcharging/overdischarging; regular inspection of the power status can extend the lifespan.
Environment and maintenance
Large-capacity batteries need to be selected in areas with frequent rainy weather; regularly clean the dust on the surface of the solar panel to prevent the hot spot effect.
3. Overall system lifespan recommendations
Ideal configuration: laminated packaging solar panel + lithium battery + waterproof lamp body, with a lifespan of up to 15-25 years.
General use: The lead-acid battery system has a lifespan of about 10 years, and the battery needs to be replaced regularly (5-8 years cycle)
