In recent years, the Earth’s energy resources have become increasingly scarce, and pollution has worsened, placing an immeasurable burden on the planet. Safe and environmentally friendly renewable energy has become a savior in people’s eyes, being “inexhaustible and sustainable.” Among renewable energy sources, solar energy is particularly prominent and widely applied. Today, solar power generation in the lighting field has become more refined, and solar garden lights are gradually forming a scale. So, are solar garden lights durable? What factors influence their lifespan? Below, the editor from Century Sunshine Lighting will introduce this topic.
1. Choosing the right battery packaging form
The packaging form of solar panels is designed to extend their lifespan and protect the battery from bending and damage. Currently, there are two types of packaging: lamination and potting. The lamination process can ensure that solar panels have a working life of up to 25 years, while potting, although aesthetically pleasing, only provides a lifespan of 1-2 years. Therefore, potting packaging can be used for solar lawn lights that do not have high lifespan requirements, while for solar lights with specified usage durations, it is recommended to use laminated packaging.
2. The quality of the battery is closely related
There are many types of batteries for solar garden lights, each with different lifespans based on their working principles. The quality of the batteries directly affects the longevity of the garden lights.
3. The battery capacity must be reasonably selected
Because the energy input from the solar lighting system is unstable, a battery system must be configured to operate. Typically, this includes lead-acid batteries, nickel-cadmium batteries, and nickel-metal hydride batteries, with their capacity selection directly influencing the reliability and cost of the system. When selecting battery capacity, it must meet nighttime lighting requirements while ensuring that daytime energy is stored to meet the power consumption during continuous rainy days. If the battery capacity is too small, nighttime lighting will be insufficient, while if it is too large, the battery will be persistently in a state of discharge, negatively impacting its lifespan.
The above factors influencing the lifespan of solar garden lights have been shared here. In summary, solar batteries play a significant role in the lifespan of solar garden lights. To prolong the lifespan of solar garden lights, it is essential to choose batteries with laminated packaging and ideal capacity, and to ensure reasonable use in the future to extend their lifespan.
