A successful solar street light project solution must produce the required illumination every night—not merely look acceptable on a product datasheet. Roads, industrial zones, residential areas, campuses and public spaces each need a site-specific combination of optics, pole geometry, solar generation, battery storage and controls.

For project owners and EPC contractors, the objective is to convert a performance brief into a system that can be priced, tested, installed and maintained with clear accountability.

Start With Lighting Performance

Do not begin with lamp wattage. Begin with:

• Road or area classification
• Maintained illuminance
• Uniformity requirement
• Glare limitation
• Color temperature
• Pole height and spacing
• Road width and setback
• Pedestrian and vehicle activity

Ask the supplier for photometric files and a lighting calculation using the proposed pole layout. This helps the consultant determine whether the luminaire distributes light where it is needed rather than producing a high lumen figure without usable uniformity.

Complete the Solar Energy Balance

The solar panel, battery, controller and lighting schedule must function as one system.

The calculation should include:

• Location-specific solar irradiation
• Seasonal low-sun conditions
• Panel orientation and shading
• Controller and wiring losses
• Battery depth of discharge
• Temperature effects
• Battery aging allowance
• Required consecutive nights of autonomy
• Hour-by-hour dimming schedule

MPPT charging can improve energy capture under variable conditions, but it cannot correct an undersized panel or unrealistic nightly load.

Select the Right ANETHIC Configuration

Lightgogo 4 for All-in-One Projects

Lightgogo 4 covers 40W to 180W and integrates the LED luminaire, solar generation, LiFePO4 storage and MPPT control. Its compact architecture is suited to distributed road, residential and commercial installations.

Lightgogo 4 Hybrid for Critical Locations

The hybrid range covers 40W to 180W and combines solar with grid backup. It can suit high-priority roads or sites where the client wants solar savings and another energy source.

Lightgogo 5 for Programmable Outdoor Lighting

Lightgogo 5 covers 30W to 60W with remote programming and optional IoT monitoring. It is suitable for pathways, gardens, campuses and applications where operating profiles need adjustment after installation.

Lightgogo 3 for Economical Deployment

Lightgogo 3 covers 30W to 40W in a plug-and-play all-in-one format for lower-demand roads and public spaces.

Case Study: 210 Lightgogo 4 Units in Abuja

ANETHIC's published 2021 Abuja project lists 210 all-in-one Lightgogo 4 solar road lights. The system configuration included:

• 60W LED power
• 180 lm/W stated efficacy
• 12.8V 36Ah LiFePO4 battery
• MPPT controller with 98% stated efficiency
• Microwave motion sensing
• 8-meter mounting height
• 40-meter spacing
• Operating temperature of –10°C to 60°C

The project page reports twelve hours of illumination using reduced output and full brightness on demand. This illustrates the role of programmable lighting: the energy budget is managed over the entire night rather than operating continuously at maximum output.

These figures are useful as project evidence, not as a universal design template. A new location requires its own photometric and solar calculation.

Case Study: 380 Split-Type Lights in Coastal Brazil

ANETHIC's Brazil project used 380 split-type systems with 35W luminaires, 160W monocrystalline panels, 150Ah gel batteries, 6-meter poles and dimming controllers.

The published design targeted:

• 8–12 hours of lighting per night
• Three days of autonomy
• Average ground illuminance of 15 lux
• Independent operation without grid extension

The split architecture allowed the panels to be positioned independently for solar exposure and maintenance. It also demonstrates why the battery technology and physical configuration should be selected around the project's environment and service strategy.

Seven Stages of Solar Street Light Project Delivery

1. Site Survey

Record coordinates, road dimensions, shading, existing infrastructure, pole locations, soil conditions and environmental exposure.

2. Performance Specification

Define the lighting standard, maintained lux, uniformity, glare, color temperature and operating schedule.

3. Photometric Design

Model the proposed luminaire, mounting height and spacing. Review dark areas, glare and edge illumination.

4. Energy and Autonomy Design

Size the panel and battery using local solar data and the programmed load profile.

5. Mechanical and Electrical Review

Check wind loading, brackets, fasteners, corrosion protection, ingress protection, surge protection and battery operating range.

6. Pilot Installation

Test a representative section before mass production. Measure illumination, verify controls and confirm installation procedures.

7. Commissioning and Handover

Document serial numbers, settings, inspection results, training, spares and the warranty process.

Procurement Documents to Request

A complete tender response should contain:

• Specification compliance schedule
• Product and component datasheets
• Photometric calculation and IES/LDT files
• Solar-energy calculation
• Autonomy assumptions
• Drawings and installation manuals
• Control and programming instructions
• Test and quality records
• Model-specific certification evidence
• Packaging, lead time and logistics plan
• Warranty and recommended spare parts

ANETHIC's homepage states that its products are TÜV and IEC certified. Buyers should verify the relevant certificate and covered model rather than accepting a general statement as project compliance evidence.

Calculate Project ROI

Compare solar lighting with the realistic conventional alternative. Include:

• Luminaires, panels, batteries and controllers
• Poles, brackets and foundations
• Installation and transport
• Trenching, cabling and grid connection
• Electricity over the analysis period
• Cleaning and inspection
• Battery and electronic component replacement
• Failure response and site access

Solar can be particularly attractive when grid extension is expensive or disruptive. Smart dimming reduces unnecessary load during low-traffic hours, allowing the energy system to be sized around actual activity rather than maximum output all night.

Frequently Asked Questions

How many days of autonomy should a solar street light provide?

There is no universal answer. It depends on seasonal solar conditions, lighting criticality, allowable dimming and project risk tolerance. State the required low-sun period in the tender.

Is an all-in-one or split system better?

All-in-one systems simplify deployment. Split systems provide flexibility in panel positioning and component access. The correct choice depends on climate, maintenance, aesthetics, theft risk and economics.
