20 Watt | 24 Hours | Long Backup | IP64 Rating | Day & Night Sensor | Motion Sensor | 160° Coverage – Solar Street Light

Overview

The 20W Solar Street Light (Aero Model 1184) is a compact, all-in-one off-grid outdoor lighting solution designed for residential colony internal roads, housing society pathways, rural gram panchayat lanes, farmhouse driveways, small parking lots, and low-to-medium traffic suburban streets across India. Featuring 640 LED 5730 EPISTAR chips producing a combined 250W output and a 3.2V 25Ah LiFePO4 battery rated for an exceptional 24 Hours of Long Backup, the 1184 delivers multi-night backup capability that differentiates it from single-night competitors widely listed online at this wattage. Built with IP64 weatherproofing, a Day & Night Sensor for automatic dusk-to-dawn switching, a Motion Sensor for intelligent brightness management, and a wide 160° Coverage beam pattern, the Aero Model 1184 integrates all components into a single pre-assembled unit for installation on a 45mm pole at heights of 5–7 metres — with no external wiring or grid connection required.

LED Performance & Light Output – 160° Coverage

The Aero Model 1184 integrates 640 LED 5730 EPISTAR chips at a combined LED power of 250W in cool white, delivering a wide 160° Coverage beam pattern that maximises road surface illumination across colony internal roads, housing society pathways, and rural gram panchayat lanes at the 5–7 metre installation height. The 160° beam spread ensures uniform ground-level coverage across the full width of residential roads and shared access tracks, reducing dark spots and inter-pole gaps that are common with narrower-beam competitors at equivalent mounting heights. EPISTAR is a Taiwanese LED manufacturer whose 5730 chip series is widely regarded as a benchmark for high-lumen-density, thermally stable SMD LEDs in commercial outdoor lighting. The 5730 chip’s larger light-emitting surface area compared to standard 5050 or 3030 chips produces higher lumen output per chip while maintaining lower junction temperatures — critical for consistent illumination in India’s high-ambient-temperature summer conditions across Rajasthan, Telangana, Gujarat, and Maharashtra. With 640 chips spread across the Aero Model housing, the 1184 delivers an even, uniform beam across its full 160° illumination zone, providing sharp contrast for vehicle and pedestrian movement on colony roads and parking areas.

Battery – LiFePO4 25Ah Capacity & 24-Hour Long Backup

The 3.2V 25Ah LiFePO4 battery in the Aero Model 1184 is the core enabler of its 24-hour Long Backup rating — a genuine differentiator from the vast majority of 20W solar street lights available online, which typically claim only single-night backup. LiFePO4 (Lithium Iron Phosphate) chemistry provides over 2,000 charge-discharge cycles at 80% depth of discharge, equating to more than five years of daily operation before meaningful capacity degradation occurs. Unlike lead-acid batteries used in budget solar street lights, LiFePO4 does not suffer from sulphation during partial charge states — a common failure mode during India’s monsoon months when consecutive overcast days prevent full charging. The 25Ah capacity, combined with the Motion Sensor’s intelligent dimming, reliably sustains the 250W LED array across two full dusk-to-dawn cycles between charges, delivering the 24-hour Long Backup performance even through partial-charging monsoon days in coastal and north-eastern Indian states.

Body Build & Weatherproofing – IP64

The Aero Model 1184 carries an IP64 weatherproofing rating, confirming complete protection against dust ingress and resistance to directed water jets — the minimum outdoor lighting standard recommended for India’s monsoon climate and endorsed by procurement specifications for gram panchayat, municipal, and housing society road lighting projects. The unit measures 60 × 34.2 × 10 cm, a compact flat-panel profile that minimises wind load across the full 160° Coverage arc at the 5–7 metre installation height. Pole diameter compatibility is 45mm, matching standard GI poles widely used in Indian residential and municipal lighting projects and enabling direct replacement of existing pole hardware without modification. The sealed Aero housing construction protects all internal electronics, the LiFePO4 battery, and the LED driver from moisture infiltration, thermal cycling, and dust accumulation — the primary causes of premature failure in non-IP-rated solar street lights at lower price points in the Indian market.

Smart Controls – Day & Night Sensor | Motion Sensor | 160° Coverage

The Aero Model 1184 operates fully automatically through two integrated sensing systems — a Day & Night Sensor and a Motion Sensor — ensuring hands-free dusk-to-dawn performance across the full 160° Coverage zone without any manual switching. The Day & Night Sensor activates the unit automatically at dusk and switches it off at dawn across all seasons, providing consistent year-round coverage on colony roads and rural pathways where manual daily switching is not operationally feasible. The Motion Sensor manages a three-state brightness sequence across the 160° detection arc: 10% standby brightness during inactive periods, 100% full brightness on motion detection, and 15% brightness for 30 seconds post-motion before returning to standby. This three-state dimming logic is essential for sustaining the 24-hour Long Backup on low-to-medium traffic colony roads and rural pathways where full brightness is not required throughout the night. The included wireless remote control provides additional flexibility with OFF (full dusk-to-dawn switch-off), ALWAYS (motion sensor off, constant dusk-to-dawn illumination), INDUCTION (full radar-active dusk-to-dawn), and timed induction modes at 2H, 4H, and 6H — the 6H mode being particularly suited to gated community entry roads and commercial parking areas where activity is concentrated in the early evening hours.

Solar Panel & Charging Efficiency

The 5V 29W monocrystalline solar panel integrated into the Aero Model 1184 provides the daily energy harvest required to replenish the 25Ah LiFePO4 battery within 6–8 hours of direct sunlight. Monocrystalline silicon cells achieve conversion efficiencies of 19–22% under standard test conditions, outperforming polycrystalline alternatives (13–17%) under both full sun and diffused light — the latter being common across India during the June–September monsoon season and the shorter, lower-angle winter days of north India (November–January). The relatively high panel wattage of 29W relative to the 25Ah battery capacity ensures the 24-hour Long Backup specification is achievable even under the reduced solar insolation conditions of north Indian winters. Compared to competing 20W solar street lights that pair lower-rated panels with larger backup claims, the 1184’s 29W monocrystalline panel provides a technically sound basis for its Long Backup performance rating. The factory-integrated panel eliminates on-site tilt adjustment for large installation volumes.

Installation & Mounting

Installation of the Aero Model 1184 requires no external wiring, trenching, conduit work, or grid connection. The complete pre-assembled unit — solar panel, LiFePO4 battery, LED module, Day & Night Sensor, Motion Sensor, and controller — is bracket-mounted to a 45mm diameter pole at 5–7 metres height, positioning the 160° Coverage beam at the optimal height for uniform road surface illumination on colony internal roads and rural gram panchayat lanes. Total on-site installation time per unit is typically under 30 minutes, making the 1184 suitable for large-volume colony road lighting projects and rural gram panchayat road schemes where installation efficiency directly affects project cost. The off-grid design is directly relevant to the most common solar street light use cases in India — peri-urban housing developments without completed grid infrastructure, rural roads under PM Gram Sadak Yojana and state rural road programmes, and farmhouse or agricultural estate perimeter roads where laying underground power cables is cost-prohibitive. At 5 units per carton, procurement logistics for housing developers, contractors, and municipal bodies are straightforward.
