San Salvador Smart Streetlight Rollout: 141 Hybrid Poles with EV Charging

San Salvador’s Multi-Function Pole Strategy

San Salvador’s latest street infrastructure upgrade shows how a single pole can replace multiple roadside assets without sacrificing capability. The city deployed 141 SOLARTODO Smart Streetlight units on 11m hybrid poles, each spaced 35m apart, to combine lighting, EV charging, communications, safety, and digital signage in one engineered structure. For dense urban corridors, this kind of consolidation reduces civil works, simplifies maintenance, and improves asset density per meter of right-of-way.

Why this architecture matters

The project responds to a familiar municipal problem: traditional lighting poles usually do one job, while cities increasingly need public lighting, surveillance, emergency response, and curbside charging in the same footprint. The World Bank (2023) notes that integrated urban infrastructure can improve service efficiency by reducing fragmented maintenance responsibilities. In parallel, the IEA (2024) highlights that public charging visibility and accessibility remain key barriers to EV adoption in emerging markets.

Core Technical Stack

Pole, lighting, and charging integration

Each unit uses an 11m octagonal tapered steel pole with a 45cm base diameter and 15cm top diameter. The lighting package includes 2×80W LED luminaires mounted on twin 1.5m arms with +8° tilt, producing 4000K output at 150 lm/W efficacy. The lower 2.2m of the structure houses the EV charging cabinet, which supports a 7kW dual-gun AC charger with 2× Type 2 connectors and OCPP 1.6J.

This is also where the design becomes especially relevant for B2B smart-city procurement: the same structure can be specified as a cylindrical Ø219mm flush-integrated pole in related deployments, or as a hot-dip galvanized RAL8011 monolithic pole where corrosion resistance and finish consistency are priorities. SOLARTODO’s approach is to keep the pole as a systems platform, not just a lighting mast.

Self-power and edge infrastructure

The hybrid energy layer combines a 500W Darrieus H-type VAWT, 2×100W monocrystalline solar panels tilted at 15°, and a 5kWh LFP battery managed by MPPT. On the edge-computing side, each cluster includes a WiFi 6 access point mounted at 8.7m, supporting up to 256 devices and throughput of 1.8Gbps per pole cluster. Public safety hardware includes a 360° mini PTZ camera with 20x zoom and 100m IR, plus one-press SOS, dual-way intercom, and a 30W IP audio column.

Deployment Specs at a Glance

Key unit-level parameters

Standards, Context, and Delivery Logic

Compliance and urban utility density

The deployment aligns with IEC 60598, GB/T 37024, and IEC 62196-2, which matters because municipalities need infrastructure that is not only functional but also standards-based and maintainable. The integrated 1280×2560mm P5 display adds another layer of utility, with fixed branding content reading “SOLARTODO Smart City” and brightness above 5000 cd/m² for daylight readability.

What this means for smart-city operators

For cities evaluating next-generation streetscape assets, the San Salvador project demonstrates that one pole can support lighting, EV charging, communications, emergency services, and digital messaging simultaneously. That is the core value proposition behind SOLARTODO’s system design: fewer standalone cabinets, fewer pole types, and a cleaner operational model for municipal teams.
