20 Watt | 12 Hours Backup | IP64 Rating | Day & Night Sensor | Motion Sensor | Battery Level Indicator – Solar Street Light

Overview

The 20W Solar Street Light (Aero Plus Model 1347) is an all-in-one, off-grid outdoor lighting system designed for housing colony roads, residential society parking lots, rural gram panchayat pathways, farmhouse driveways, and low-to-medium traffic suburban streets across India. Equipped with 576 LED 5730 chips and a 3.2V 20Ah LiFePO4 battery rated for 12 Hours of illumination, this unit stands out in its segment with features like a Day & Night Sensor, Motion Sensor (Radar), and a Battery Level Indicator — a critical differentiator confirmed by buyer search patterns online. The Aero Plus body design integrates the solar panel, battery, LED module, radar sensor, and wireless controller into a single compact unit at installation heights of 4 to 5 metres, with no external wiring or grid connection required.

LED Performance & Light Output

The Aero Plus 1347 integrates 576 LED 5730 chips at 20W output in cool white light. LED 5730 chips are a professional-grade SMD LED variant widely specified in commercial outdoor lighting for their superior lumen efficacy and thermal performance compared to standard 5050 or 3030 chips. The high chip count — 576 individual 5730 LEDs — ensures very even light distribution with low localised intensity, reducing glare on residential streets and colony pathways where pedestrians are the primary user. Cool white output maximises contrast and visibility for both foot traffic and slow-moving vehicles. The 12-hour lighting capability is driven by the combination of high-efficiency LEDs and intelligent radar-based motion sensing that reduces power draw during no-motion periods, extending battery runtime reliably through the night.

Battery – LiFePO4 20Ah Capacity & 12-Hour Backup

The 3.2V 20Ah LiFePO4 battery in the Aero Plus 1347 is the primary enabler of its 12-hour backup rating — a performance level markedly superior to shorter-duration lead-acid or standard Li-ion solar street lights sold in the Indian market at comparable price points. The integrated Battery Level Indicator allows users or maintenance teams to check charge status at a glance without dismounting the unit. LiFePO4 (Lithium Iron Phosphate) chemistry offers over 2,000 charge-discharge cycles at 80% depth of discharge, translating to more than five years of reliable daily operation without capacity degradation. Unlike lead-acid batteries, LiFePO4 cells do not suffer from sulphation during partial-charge states — a common issue during India’s monsoon months when consecutive overcast days reduce solar input. The chemistry is also thermally stable at the high ambient temperatures prevalent in Rajasthan, Gujarat, Telangana, and other hot-climate Indian states, unlike standard Li-ion cells that can present thermal risks above 45°C.

Body Build & Weatherproofing

The Aero Plus Model 1347 carries an IP64 weatherproofing certification, confirming complete protection against dust ingress and resistance to water jets from any direction. IP64 is the standard minimum for outdoor lighting in India’s monsoon-affected climate, making this unit suitable for year-round unattended operation across coastal, semi-arid, and high-humidity agricultural regions. The compact body dimensions of 42 × 35 × 9 cm reduce wind load at the 4–5 metre installation height. Pole compatibility is 45mm diameter, compatible with standard GI poles widely used in Indian housing society and gram panchayat road projects. The sealed housing construction prevents moisture infiltration, dust accumulation, and insect ingress — common failure causes in non-IP-rated solar lights available at lower price points.

Smart Controls & Operating Modes

The 1347 features a Day & Night Sensor and a Radar-Based Motion Sensor, along with a wireless remote control providing multiple operating modes. The day & night sensor ensures the light activates automatically at dusk and switches off at dawn — no manual intervention required. The motion sensor activates at 10% optical brightness initially, triggers 100% brightness on motion detection, then holds at 15% brightness for 30 seconds post-motion before returning to standby — a pattern that maximises battery autonomy across the 12-hour operational window on low-traffic colony roads and rural village pathways. Remote control modes include 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 intervals. The 6H mode is especially suited to sites with defined activity hours such as gated society entry points and commercial parking lots. All modes are accessible via the included remote without physical access to the unit.

Solar Panel & Charging Efficiency

The 5V 23W monocrystalline solar panel integrated into the Aero Plus 1347 charges the 20Ah LiFePO4 battery across a 7–8 hour daily charge window. Monocrystalline silicon panels achieve conversion efficiencies of 19–22% under standard test conditions, outperforming polycrystalline alternatives (13–17%) in both direct and diffused light conditions — particularly relevant during India’s June–September monsoon season. The 7–8 hour charging time is consistent with peak solar hours available across most Indian states between October and May, and the panel’s superior low-light sensitivity helps maintain charging performance during the shorter, cloudier days of the November–January winter period in north India.

Installation & Mounting

The Aero Plus 1347 is designed for rapid, no-wiring installation. The solar panel, LiFePO4 battery, LED array, day & night sensor, radar motion sensor, battery level indicator, and controller are factory pre-assembled into a single housing. On-site work is limited to mounting the bracket onto a 45mm diameter pole at 4–5 metres height — typically completed in under 30 minutes per light. No electrical cabling, trenching, or grid connection is required, making the 1347 suitable for rural gram panchayat road tenders, colony development projects, farmhouse perimeter lighting, and off-grid construction site access roads. Supplied at 5 units per carton, bulk procurement for housing societies, municipalities, and civil contractors is logistics-ready.
