Solar Lighting System
A standalone solar photovoltaic street lighting system (SLS) is an outdoor lighting unit used for illuminating a street or an open area. Electricity generated by the PV module charges the battery during the day time which powers the luminaire from dusk to dawn. The system lights at dusk and switches off at dawn automatically.

Features
  •   Automatic Dusk to Dawn operation
  •   High efficient LED for longer life (500000 burning hours)
  •   High efficient Solar Module with 25 Years linear performance warrantee
  •   Substantial power saving
  •   Easy to install electronics driver with higher efficiency
