Solar Street Lights
Solar street lights charge during the day and light up at night with no cabling or electricity bill.
Designs
- All-in-one: panel, battery and lamp in one unit, quick to install.
- Split: separate panel and battery for larger or custom setups.
What to specify
- Lumen output and mounting height
- Battery autonomy for cloudy days
- Pole strength and wind rating
- Controller with dusk-to-dawn and dimming
Placement
Panels must see the sun, so avoid tree shade. Hill roads need extra care with pole foundations.
Specifying lights for a project
Decide the road width, pole spacing and lighting level needed, then ask for the supplier’s autonomy rating under cloudy conditions. For campuses and villages, consider remote-fault visibility and an easy way to replace batteries. Cheap units without a proper charge controller often fail early.
Ownership and upkeep
Assign who inspects the lights monthly and who replaces failed batteries. Unattended solar lights commonly fail because nobody is responsible for them.
Frequently asked questions
How long do they run at night?
It depends on battery size and settings; ask for rated autonomy.
What maintenance is needed?
Clean the panel and check batteries periodically.
