499 units, 5 m poles, and a 6 m road corridor
A 499-unit split-type solar streetlight layout for San José is built around a simple constraint: a 6 m road can be lit without trenching if the pole, battery, and generation stack are sized correctly. In the referenced configuration, each node uses a 5 m hot-dip galvanized steel pole, a 40 W LED head, a 500 W Mono PERC solar panel, and a 200 W horizontal-axis wind turbine (HAWT). The pole spacing is 15 m, and the structure is rated for 45 m/s wind resistance, which matters in tropical urban corridors where exposed roadside hardware must survive gust loading.
For procurement teams, the key point is that this is not an all-in-one luminaire. It is a split-type architecture with the battery and control gear separated from the light head, which improves service access and reduces rooftop-style thermal stress on the battery enclosure. SOLARTODO positions this format for municipal roads, access roads, and public-path lighting where maintenance crews need direct access to the battery box and controller.
| Spec | Value |
|---|---|
| Deployment scale | 499 units |
| Pole height | 5 m |
| Pole spacing | 15 m |
| Road width target | 6 m |
| LED power / output | 40 W / 6,000 lm |
| LED efficacy | 150 lm/W |
| Solar panel | 500 W Mono PERC |
| Wind generator | 200 W HAWT |
Electrical architecture and autonomy
The lighting head is specified at 40 W and 6,000 lm, which gives an efficacy of 150 lm/W. That output level is appropriate for local streets and pedestrian connectors when paired with the stated spacing. The hybrid top assembly combines wind and solar generation to support nighttime operation during cloudy periods, which is relevant in San José’s tropical climate and its reported about 5.5 peak-sun-hours.
The battery subsystem is a visible external 12 V / 100 Ah LiFePO4 box mounted on the pole body. The design uses MPPT control, 90% depth of discharge, and a rated life of 3,500 cycles. Backup autonomy is specified at 3-5 days of cloudy operation, which is the main resilience parameter for municipal buyers evaluating off-grid lighting versus grid-tied trenching.
Control functions that affect lifecycle cost
Two control features are called out in the configuration: motion sensing and dimming. Motion sensing can reduce lighting energy demand by about 30%, while dimming can reduce it by 15%. In practice, that lowers battery throughput and can extend maintenance intervals, especially on lower-traffic streets.
Standards, siting, and procurement fit
The technical framing aligns with IEC 60598 for outdoor luminaires and IEC 62124 for PV-system performance verification, with the system also referenced against CJJ 45-2015. For a municipal buyer, the engineering question is not whether the unit is decorative; it is whether the pole class, battery access, and hybrid generation stack match the road geometry and service model.
In San José, where dense urban blocks and constrained right-of-way are common, a 5 m / 40 W / 500 W / 200 W split-type package is a practical specification for distributed lighting assets. It is best evaluated as a resilience-focused streetlighting node for approximately 499 poles, not as a generic solar lamp.
