1.1	Supply, Installation, Testing, and Commissioning (SITC) of an integrated solar photovoltaic (PV) lighting system designed for mounting on existing pole structures. The system comprises a 6V, 150W Mono Crystalline Solar Panel (minimum efficiency 21%) and a 12.8V, 42Ah Lithium Iron Phosphate (LiFePO4) battery providing a minimum backup time of 12 hours with an 8–10 hour charging cycle. It features an integrated PWM/MPPT charge controller housed in a sleek, sturdy, weather-proof, and easy-to-install enclosure with built-in under-voltage and over-voltage protection. The luminaire utilizes a 30W LED fixture (12.8V DC input) with an operating temperature range of -5°C to 50°C. The electrical circuitry includes internal 5kV (L, N, E) surge protection as per IEC 61000-4-5, driver efficiency >85%, and EMI/EMC compliance as per CISPR 15. The fixture is rated IP66 and IK08, featuring a Correlated Color Temperature (CCT) of 5700K (ANSI Bin), CRI >70, and optical lenses delivering IESNA Type I, II, or III beam angles depending on road width and project requirements. The complete system (LED, driver, and electrical circuitry) guarantees a minimum lifespan of 50,000 burning hours to L70 (70% initial lumen maintenance) as per IES. TM-21-11 report,	-	-	-	-
