Project Case Study

Highway Interchange Solar Street Lighting in Yemen

Solar street lighting for highway interchanges in Yemen, with median dual-arm poles, branching roads and rocky shoulders along vehicle approach routes.

Project Brief

This highway interchange solar street lighting proposal in Yemen specifies 426 sets of DEL-DS10-120 All-in-Two Solar Street Lights for branching roads and vehicle approaches. Reference photographs show central medians, rocky shoulders and low roadside buildings, with dual-arm solar poles following the main approach. The planned layout uses 9 m poles at 30 m intervals across a stated 7 m road width. Neutral 4000K lighting is intended to support nighttime visibility where vehicles approach junctions, merge and change travel direction.

Selected Lighting solution

The DEL-DS10-120 All-in-Two Solar Street Light is specified for this highway interchange proposal in Yemen. Separate photovoltaic panels and LED luminaires accommodate the proposed median dual-arm arrangement. The configuration pairs a 120 W LED with a 250 Wp monocrystalline panel, 1536 Wh LiFePO4 battery and MPPT controller. A proposed timed dimming schedule adjusts overnight output, subject to interchange lighting assessment and energy verification.
