1. Technical Assessment
12W Solar Street Light: Recommended light output for basic illumination. Typically produces around 1,200 to 1,500 lumens (assuming LED efficiency of ~100–130 lm/W).
12.8V Battery: Standard nominal voltage for a Lithium Iron Phosphate (\text{LiFePO}_4) battery pack (4 cells in series at 3.2V each). \text{LiFePO}_4 is ideal for street lighting due to its long cycle life (2,000+ cycles) and safety.
75W Solar Panel: Generously sized for a 12W LED load. On a standard 5 to 6-hour full-sun day, a 75W panel generates ~375Wh–450Wh, which comfortably recharges a typical 12.8V battery system for overnight operation (10–12 hours).
6m GI Pole: Galvanized Iron pole providing excellent corrosion resistance and an optimal mounting height (6 meters / ~20 feet) to spread light over a 15–20 meter stretch of road or driveway.
