Solar & Outdoor Lighting Specifications

Published: September 2026 | Category: Lighting Specifications | Keywords: solar LED light specs, outdoor lighting specifications, solar street light, solar flood light, off-grid lighting, IP66 outdoor LED

1. Overview

Solar LED lighting combines photovoltaic generation, battery storage, and LED output in a self-contained system. These off-grid fixtures are deployed in remote locations, rural roads, parks, and commercial perimeters where grid connection is unavailable or cost-prohibitive. Key performance metrics extend beyond luminous flux to include autonomy (nights of operation without recharge), solar panel efficiency, and battery cycle life.

2. Product Categories

Solar Street Lights

All-in-one and split-type solar street lights for rural roads, community areas, and perimeter security. 20W-120W.

Solar Flood Lights

Solar-powered area lighting for yards, parking lots, and signage. Motion sensor activation for energy saving.

Solar Garden Lights

Decorative solar lights for landscaping, pathway, and park illumination. Low-output, high-aesthetic fixtures.

Grid-Tied Street Lights

Mains-powered LED street lights with optional solar backup for grid- unreliable areas.

3. Complete System Specifications

Parameter Specification Range Notes
LED Power 20W – 120W LED module rated power
Luminous Flux 1,600 – 13,000 lm Actual output depends on dimming profile
Solar Panel Power 30W – 200W (mono/poly) Monocrystalline preferred for efficiency
Solar Panel Efficiency 18% – 23% Mono > Poly in all conditions
Battery Type LiFePO4 (preferred) / Li-ion / Gel LiFePO4: 2000+ cycles, safe, wide temp
Battery Capacity 300Wh – 1200Wh For 2-5 night autonomy
Battery Cycle Life LiFePO4: 2000+ / Li-ion: 800+ / Gel: 500+ At 80% DoD, 25C
Autonomy 2 – 5 nights (rainy/cloudy) Without solar recharge
Charge Time 4-6 hours (full sun) MPPT controller for max efficiency
CCT 3000K / 4000K / 5000K / 5700K 5000K standard for street lighting
CRI Ra70+ (standard) / Ra80+ (premium) Higher CRI for pedestrian areas
IP Rating IP65 / IP66 / IP67 IP66 minimum for outdoor
Wind Rating Up to 150 km/h (42m/s) Mounting pole and bracket rated
Operating Temp -30C to +60C Battery performance degrades below 0C
Controller MPPT with smart dimming Motion sensor + time + light control modes
Lifespan LED: 50,000h / Battery: 5-8 years Battery is limiting component

4. Smart Control Modes

Mode Operation Energy Use
Time Control Full brightness for X hours, then off Highest
Motion Sensor 20% dim, 100% when motion detected Lowest (extends autonomy 3-5x)
Dual-Period 100% first 4h, 50% next 4h, 20% after Medium
Adaptive Auto-adjust based on remaining battery Smart
Remote (IoT) 4G/NB-IoT remote monitoring & control Variable

5. Sizing Methodology

Solar Light Sizing Example

Given:
– Target: 40W LED, 8 hours/night operation
– Location: 30 degrees latitude, 5 peak sun hours
– Required autonomy: 3 nights (rainy days)

Daily energy need = 40W x 8h = 320Wh
Battery capacity (with 80% DoD) = 320Wh x 3 nights / 0.8 = 1,200Wh
Solar panel (with 70% system efficiency) = 320Wh / (5h x 0.7) = 91W
Recommended: 100W solar panel + 1,200Wh LiFePO4 battery + 40W LED module
