80W Solar Street Light Outdoor Lighting Solution

80W Solar Street Light Outdoor Lighting Solution

October 06, 2025
A 80W solar street light is a medium-power outdoor lighting solution that integrates solar energy collection, storage, and LED illumination.
 
It balances brightness, energy efficiency, and application scenarios—suitable for residential communities, rural roads, parks, factory campuses, and other areas with moderate lighting needs (not ultra-high-brightness scenarios like highways).
 
Below is a comprehensive guide to its core components, performance parameters, selection criteria, installation considerations, and application scenarios, helping you fully understand its value and how to choose the right product.

I. Core Components of 80W Solar Street Lights (Determine Performance & Lifespan)

 
An 80W solar street light is a systematic product, and the quality of each component directly affects its stability and service life.
 
The key components include:
 
 
Component Function Key Quality Indicators
Solar Panel Convert sunlight into electrical energy and charge the battery. - Power: Usually 120W–200W (needs to match the 80W LED load; 1.5–2x the LED power is optimal for efficient charging).
 
- Type: Monocrystalline silicon (higher conversion rate: 22–24%, better for areas with insufficient sunlight) > polycrystalline silicon (18–20%, cost-effective).
 
- Protection Grade: IP65 or higher (resists rain, dust, and corrosion).
LED Light Source Provide illumination (core load of 80W). - Power: Strictly 80W (avoid false marking; actual power affects brightness).
 
- Luminous Efficacy: ≥130lm/W (higher = brighter under the same power; 80W can reach 10,400lm, equivalent to a 250W traditional sodium lamp).
 
- Color Temperature: 3000K (warm white, suitable for residential areas) or 5000K (cool white, suitable for roads/parks).
 
- Lifespan: ≥50,000 hours (reduces replacement frequency).
Battery Store electrical energy for nighttime illumination. - Type: Lithium iron phosphate (LiFePO₄, preferred—safe, long lifespan: 3000–5000 cycles, wide temperature range: -20°C–60°C) > lead-acid (cheap but short lifespan: 800–1200 cycles, poor low-temperature performance).
 
- Capacity: 100Ah–150Ah (12V system; ensures 3–5 rainy days of continuous illumination).
 
- Protection: Overcharge/over-discharge protection (prevents battery damage).
Controller Manage charging/discharging (brain of the system). - Intelligent Modes: Light control (auto-on at dusk, auto-off at dawn) + time control (e.g., 100% brightness for 4h, 50% brightness for 6h to save energy).
 
- Protection Functions: Overcurrent, short circuit, reverse polarity protection (avoids component burnout).
 
- Efficiency: ≥95% (reduces energy loss).
Lamp Pole & Housing Support the light and protect internal components. - Lamp Pole Material: Galvanized steel (anti-rust, load-bearing ≥50kg; height 5–8m, matching 80W’s illumination range).
 
- Housing Protection Grade: IP67 or higher (resists heavy rain, dust, and accidental water splashing).
 
- Heat Dissipation: Aluminum alloy housing (good heat dissipation for LEDs, preventing overheating and lifespan reduction).

II. Key Performance Parameters (Avoid "False Marketing")

 
When selecting an 80W solar street light, focus on actual performance rather than just nominal parameters. Below are the most critical indicators to verify:
 
All in One Integrated Solar Street Light
 
 
 
  1. Illumination Effect
    • Luminous Flux: 80W LED should reach 10,000–11,000lm (if below 9,000lm, it may be underpowered).
    • Illumination Range: For a 6m lamp pole, the effective illumination radius is 8–12m, and the average illuminance on the ground is 15–30lux (meets national standards for residential roads: ≥10lux; park roads: ≥15lux).
    • Uniformity: Illuminance uniformity ≥0.4 (no obvious dark areas).

 

  1. Weather Adaptability
    • Working Temperature Range: -30°C–70°C (suitable for most regions in China, including northern cold areas and southern high-temperature areas).
    • Wind Resistance: Lamp pole wind resistance grade ≥12 (resists strong winds of 32.7m/s, common in coastal or windy areas).
    • Rainy Day Endurance: ≥3 days (continuous illumination with 50% brightness when there is no sunlight for 3 consecutive days; high-quality models can reach 5 days).

 

  1. Energy-Saving & Durability
    • Charging Efficiency: Solar panel conversion rate ≥22% (monocrystalline silicon) to ensure fast charging even in weak sunlight (e.g., cloudy days).
    • Battery Cycle Life: LiFePO₄ batteries ≥3000 cycles (can be used for 8–10 years; lead-acid batteries need replacement every 2–3 years).
    • LED Lifespan: ≥50,000 hours (used 8 hours/day, can last 17 years).

 

FAQ

Q. Can you do OEM?

A: Yes, we are a 25-year-old factory with a team of designers, engineers, after-sales service staff, and QC staff.

 

Q. How is shipping?

A: We typically ship via DHL, UPS, FedEx, or TNT. Delivery typically takes 3-5 days. Air and sea shipping are also available.

 

Q. Do you offer a product warranty?

A: Yes, we offer a 2-5 year warranty.

 

Q. How do you handle faults?

A: First, our products are manufactured under a strict quality control system. Second, during the warranty period, we will ship a new lamp with small orders.

For defective bulk orders, we will repair and reship. Alternatively, we can discuss a solution, including a recall, based on the actual situation.
