With the advancement of new rural construction, the sales of solar street lights, as a green energy lighting solution, have rapidly increased. Despite this, many people still doubt their lifespan, worrying that this new product's technology is not yet mature and has a short lifespan. Even if manufacturers offer a three-year warranty, consumers remain hesitant. Today, we will scientifically analyze the actual lifespan of wholesale solar street lights.
Solar street lights are an independent power generation lighting system composed of batteries, street light poles, LED lamp fixtures, solar panels, and solar street light controllers. During the day, the panels convert light energy into electricity stored in the batteries, and at night, the batteries power the LED light sources to emit light.
Solar panels are made of silicon wafers with a lifespan of about 20 years, serving as the core power generation component of the entire system.
LED light sources are composed of multiple LED chips with a theoretical lifespan of 50000 hours; under normal usage, they can last about 10 years.
Street light poles are made of Q235 steel, hot-dip galvanized for excellent rust and corrosion resistance, ensuring no rust for at least 15 years.
Currently, solar street lights mainly use gel maintenance-free batteries and lithium batteries. The normal lifespan of gel batteries is 6 to 8 years, while lithium batteries last 3 to 5 years. Although some manufacturers claim that gel batteries can last 8 to 10 years and lithium batteries at least 5 years, in actual use, attention should be paid to performance degradation. Usually, batteries need to be replaced every 3 to 5 years to ensure good lighting effects.
Controllers generally have a high waterproof sealing level and do not need to be replaced for 5 to 6 years under normal use.
Overall, the key to the lifespan of solar street lights lies in the choice and configuration of the battery. It is recommended to configure a sufficiently large capacity battery when purchasing to extend its cycle life. The larger the battery's capacity, the smaller the depth of each discharge, which will significantly enhance the lifespan of the battery. Additionally, regular maintenance and strict adherence to construction standards during installation are effective measures to extend the lifespan of solar street lights.
Through the detailed analysis above, we hope to answer your questions about the lifespan of wholesale solar street lights and provide a reference for choosing high-performance, long-lasting products. Choosing suitable solar street lights can not only help save energy and reduce emissions for the environment but also contribute to urban safety and lighting.
Anern's energy storage systems are used in the following solar applications:
Residential Backup Power:
For home use during power outages, providing up to 6 hours of continuous power for average household consumption. These systems reduce grid reliance and electricity bills while storing excess solar energy.
Commercial and Industrial Energy Management:
Installed in factories and businesses to store excess solar energy, reduce peak-hour grid consumption, and lower electricity costs. Systems are deployed in secure, ventilated locations for stability.
Off-Grid Infrastructure:
Supports meteorological/hydrological observation equipment and other critical infrastructure in remote areas without grid coverage. Battery banks store solar energy converted via inverters for reliable operation.
Agricultural Operations:
Powers farms by converting stored solar energy into AC electricity, maintaining agricultural activities during outages or grid instability.
Large-Scale Solar Projects:
Used in independent photovoltaic power stations ranging from 10KW to 50MW capacity, enabled by parallel-connected hybrid inverters for solar energy conversion and storage.
Anern solar energy products comply with international certification standards such as ISO 9001, CE, TUV, FCC, and ROHS, supporting deployment in different regional markets.
We use SMD5730, EPISTAR and LG 3030 LED chips, with high light efficiency, low power consumption, wide luminous Angle and other characteristics.
Anern supplies integrated solar energy storage systems that combine lithium battery storage with solar inverters and system components for residential, commercial, and off-grid solar power applications.
If you live in a sunny place like South Africa or South America, wholesale solar street lights from Anern can easily last 10 hours at night all year round. In some Northern European countries, solar lights last for a shorter time at night in winter. In these areas, it is expected to last an average of six hours during winter.
