The designed lifespan over 8 years.
After fully charged, the solar bollard works more than 22 hours, and with light sensor it will work the whole night.
In rainy/cloudy days, there are still weak charging current for the battery, and we designed the battery with a 2-4 days back up for different model.
The solar area series take use of battery module design, which you can replace the whole module easily by yourselves.
They are pretty easy to install, the solar bollards works without main-grid electricity connected. No need wiring no need trenching, no electrician required.
We will offer 3 years warranty, during the warranty we offer free replacement if the products failed due to our factory reasons.
