Solar Street Light 15 Watt - TTSSL15W

The TTSSL15W is a 15 W split-panel street light with an unusually large battery for its output, suited to pathways, compounds and society internal roads.

Coverage and sizing

Designed for a 5 m mounting height with poles at about three times that — roughly 12 to 15 m pole to pole.

What is inside

15 W LED producing 2,400 lumens, on a 40 Ah LiFePO4 battery charged by a 32 W panel. A 40 Ah battery behind a 15 W load is generous by any standard in this catalogue — it is roughly three times what the fixture needs for one night, and that reserve is what carries it through a run of overcast days. LiFePO4 service life is 8 to 12 years.

Autonomy

This is the specification to look at if a site has partial shade, a monsoon-heavy climate, or simply cannot be visited often for maintenance. Panels still produce roughly 20 to 40 per cent of rated output under heavy cloud; the reserve above that is what decides the outcome.

Installation and warranty

Pole mounted with the panel on a separate bracket facing south. No grid connection. One year warranty.
