System architecture diagram generated from customer configuration

Key design elements:

• PV sizing: 110W Mono PERC panel per pole, matched to local irradiance in a temperate climate to recharge 864Wh usable storage within typical day length.
• Battery autonomy: 960Wh LFP battery (90% usable) provides 2 days of operation, assuming optimized dimming and motion‑based control.
• Control strategy:
  • Timer control defines base operating hours (e.g., dusk‑to‑dawn).
  • PIR sensor boosts brightness when motion is detected.
  • Dimming control reduces power draw during low‑traffic hours.

The International Energy Agency states, “Solar PV has become the cheapest source of electricity in history in many regions” (IEA, 2020). By embedding PV generation and storage into each pole, SOLAR TODO leverages this cost advantage while avoiding grid connection entirely.

Smart Functionality

The Kit Funciones Inteligentes is installed on all 2,580 units and enables:

• PIR motion detection: Raises brightness when pedestrians or vehicles are present.
• Timer‑based scheduling: Different brightness levels by time window (e.g., 100% at peak, 30–50% late night).
• Dimming profiles: Fine‑tuned energy budgeting to align with the 2‑day autonomy target.

Although remote monitoring is not enabled in this specific configuration, the control architecture is compatible with future upgrades if the client later requires centralized management.
