What is the ideal pole spacing for a solar street light for a road?

According to the photometric geometry required by standard guidelines like CIE 115 and IESNA RP-8, the industry best-practice rule is to set your Pole Spacing at 3 to 4 times the Pole Height. For example, an 8-meter pole requires 24m to 32m spacing to achieve standard-compliant illumination.

Highway & Road Solar Street Light Installation: Specs, Poles, and Best Practices for SA Contractors

Q: Does solar street light need earthing?

Yes, the metal pole must be earthed. While solar lighting operates on a low-voltage DC system, earthing is strictly required for lightning protection. If a metal light pole is not properly earthed, a nearby lightning strike will send a massive surge directly into the equipment, instantly frying the MPPT controller and lithium battery.

Q: How to set solar street light with remote?

To batch program solar street lights, program your desired dimming profile into the remote control, press the 'Send' or 'Copy' button, and then point the remote at the sensor of each light fixture while walking along the site to transmit the parameters instantly.

When bidding for road infrastructure tenders in South Africa, EPC contractors and builders face two major local realities: severe load shedding leaving highways in the dark, and rampant cable theft that renders traditional grid-tied lighting useless.

Finding a reliable solar street light for road project is the ultimate solution. However, winning a municipal or SANRAL (South African National Roads Agency) tender isn't just about offering the brightest light—it’s about tender technical compliance and seamless site execution.

In this comprehensive guide, we break down the international lighting standards (EN 13201), debunk electrical myths like whether solar street lights need earthing, and explain why partnering with a one-stop solution provider saves you major installation headaches.

1. Designing to EN 13201-2:2015 Standards: Road Classification & Pole Specs

When bidding for high-end South African municipal or SANRAL projects, rule-of-thumb estimates are not enough. The tender committee requires the lighting design to strictly comply with international standards such as EN 13201-2:2015 (Road lighting - Performance requirements).

EN 13201 is a performance-based standard. It does not dictate what pole height or wattage you must buy; instead, it specifies the exact photometric results (Luminance, Illuminance, Uniformity, and Glare) that must be achieved on the road surface based on traffic speed and volume.

Here is a breakdown of the three main road classes you will encounter in tenders, and the industry best-practice pole specs our engineers recommend to guarantee compliance with these standards:

A. Highway / Main Arterial Roads (EN 13201: M-Class)

For high-speed motorized traffic, the standard focuses on high road surface luminance (L_av) and strict disability glare control (Threshold Increment - TI).

EN 13201-2 performance requirements table for M-Class highway solar street light for road projects

(Above: EN 13201-2 target metrics for M-Class roads)

To achieve these high-speed metrics, we recommend:

Pole Height: 8m – 12m
LED Power: 80W – 150W (High-lumen output)
Pole Spacing: 30m – 40m
Beam Angle Optic: Type II / Type III (Designed for wider forward throw)

B. Municipal Urban Roads (EN 13201: C-Class & P-Class)

For low-speed urban roads, conflict areas, and walkways, the standard shifts focus to horizontal illuminance (E_av) and semi-cylindrical illuminance to ensure pedestrians can recognize faces from a safe distance.

EN 13201-2 photometric requirements table for P-Class pedestrian and urban solar led street light installations

(Above: EN 13201-2 target metrics for P-Class pedestrian & low-speed areas)

To achieve these urban metrics, we recommend:

Pole Height: 6m – 8m
LED Power: 60W – 100W
Pole Spacing: 25m – 30m
Beam Angle Optic: Type II / Type III

C. Rural Roads / Village Roads (Lower P-Class)

For remote township projects or off-grid village roads where safety and basic visibility are the primary concerns (falling under lower P5-P6 classes), a cost-effective yet reliable configuration is required.

Pole Height: 5m – 6m
LED Power: 40W – 60W
Pole Spacing: 20m – 25m
Beam Angle Optic: Type II / Type V (Depending on road width)

💡 The Engineering Rule of Spacing (Backed by CIE 115 & IESNA RP-8)

To consistently hit the overall uniformity (U_o) targets shown in the tables above without creating dark spots, optical designs must align with global roadway lighting guidelines, including CIE 115 (International Commission on Illumination) and IESNA RP-8.

Based on the photometric geometry required by these standards, the industry's best-practice rule for modern batwing lenses is to set your Pole Spacing ≈ 3 to 4 times the Pole Height. For example, an 8-meter pole typically requires 24m to 32m spacing depending on the optic lens used.

2. Proving Compliance: Why DIALux Simulation Wins Tenders

Municipal consultants do not want verbal promises; they want mathematical proof. This is why we provide comprehensive DIALux simulation reports for our EPC partners. As shown in the simulation above, our optical design proves to the tender committee that your bid achieves the exact Average Luminance (L_av) and Overall Uniformity (U_o) required by EN 13201, ensuring you pass the technical evaluation with ease.

3. Avoiding the Mix-and-Match Trap: The One-Stop Solution

Once the design is approved, site execution begins. One of the biggest headaches for SA contractors is sourcing the light fixture from Supplier A, the bracket from Supplier B, and hiring a local steelworks to make the pole. This often leads to mismatched spigot sizes, weak structural integrity, and delayed handovers.

We solve this by offering a complete solar street light with pole system, engineered specifically for municipal-grade durability:

Municipal-Grade Waterproofing: Summer thunderstorms and coastal humidity are brutal. Our solar led street light fixtures feature true IP65/IP66+ waterproof ratings, ensuring the battery and controller remain absolutely dry.
Aerodynamic & Wind-Resistant Poles: For coastal areas like Cape Town or Gqeberha, our hot-dip galvanized poles and precision brackets are engineered to withstand 35–45m/s gale-force winds, providing the optimal tilt angle for maximum solar charging.
Pre-Drilled & Matched: All components are factory-matched to fit perfectly on-site, drastically reducing your labor hours.

4. Best Practices: How to Install Solar Street Light

Proper installation ensures the longevity of the system. Here is a streamlined guide on how to install solar street light systems efficiently for highway projects:

Step 1: Foundation Pouring. Excavate the hole (typically 1/6th of the pole length). Place the anchor bolt cage (J-bolts) and PVC conduit (for the earthing wire) before pouring the concrete. Ensure it cures completely.
Step 2: Ground Assembly. Never attempt to assemble the fixtures at the top of a standing pole! Lay the pole horizontally on the ground to attach the bracket, solar panel, and light fixture.
Step 3: Plug-and-Play Wiring. Connect the aviation cables between the solar panel and the light. Our systems feature waterproof connectors—push them together until you hear a "click," and the seal is secured.
Step 4: Hoisting. Use a crane to lift the fully assembled structure. Align the base plate with the anchor bolts, tighten the nuts, and level the pole.

5. Frequently Asked Questions (FAQs)

Q1: Does solar street light need earthing?

Typical pole earthing detail CAD drawing for solar street light lightning protection

(Above: Standard CAD drawing for metal pole earthing)

Yes, the metal pole must be earthed. While solar lighting operates on a low-voltage DC system (eliminating the risk of fatal electric shock), earthing is strictly required for lightning protection.

South Africa experiences high lightning strike density. If a metal light pole is not properly earthed, a nearby lightning strike will send a massive surge directly into the equipment, instantly frying the MPPT controller and lithium battery. Proper earthing protects your asset and prevents high maintenance costs.

Q2: How to set solar street light with remote for batch programming?

When installing 100+ lights, manually climbing each pole is inefficient. Using our remote control, you can:

Program your desired dimming profile (e.g., 100% brightness for the first 4 hours, 50% till dawn) into the remote.
Press the "Send" or "Copy" button.
Walk or drive slowly along the installation site, point the remote at the sensor of each light, and press the trigger.

You can program an entire kilometer of highway lighting in minutes, ensuring uniform performance while massively saving on labor costs.
