All-in-One Solar Street Light Installation Guide

Before You Start: Tools & Preparation

Gather these tools and verify your equipment before breaking ground:

• Spirit level, measuring tape, marking paint
• Shovel, concrete mixer (for foundations)
• Crane or lift truck (for poles over 5m)
• Wrench set, socket set, torque wrench
• Multi-meter (for testing)
• Safety gear: helmets, gloves, safety vests, traffic cones

Site Survey & Pole Spacing

Before digging, mark all pole locations carefully. Key spacing guidelines:

• Standard spacing: 3.0-3.5 times the pole height. For a 6m pole, space at 18-21m intervals.
• Ensure no obstructions: Check that solar panels won't be shaded by buildings, trees, or billboards — especially during winter when the sun is lower.
• Check ground conditions: Sandy soil needs wider foundations. Rocky ground may need specialized drilling equipment.

Foundation Preparation

The foundation is the most critical step for long-term stability:

• Dig foundation pit: 60cm x 60cm x 80cm deep for a 6m pole (scale up for taller poles)
• Install anchor bolts using a template to ensure precise spacing
• Pour C25 concrete, vibrating to remove air pockets
• Keep bolts 5-8cm above concrete surface for pole flange attachment
• Cure time: 5-7 days minimum before mounting the pole. Do not rush this step.

Assemble the Light on the Pole

Assemble while the pole is still on the ground — much safer and easier:

• Attach the solar street light bracket to the pole top using the provided bolts
• Torque all bolts to manufacturer specifications (typically 40-60 Nm for M12 bolts)
• Double-check that the light fixture is securely fastened — vibration during lifting can loosen loose bolts

Raise the Pole

• Use a crane or lift truck. Position the pole base near the foundation.
• Slowly raise the pole to vertical position
• Align the pole flange holes with the anchor bolts
• Hand-tighten all nuts first, then torque in a cross pattern to specification
• Check vertical alignment with a spirit level on two perpendicular sides. Adjust with shims if needed.

Panel Orientation & Angle Adjustment

Correct orientation is crucial for energy generation:

• Northern hemisphere: Panel faces TRUE SOUTH (not magnetic south)
• Southern hemisphere: Panel faces TRUE NORTH
• Tilt angle: Set to your latitude + 10-15 degrees. For most tropical regions, 15-30 degrees works well.
• Tighten all tilt adjustment bolts securely — wind can shift loose panels

Power On & Test

• Locate the power button (usually on the bottom or side of the fixture)
• Press and hold for 3-5 seconds until the indicator light flashes
• The light should automatically turn on at dusk and off at dawn (test by covering the solar panel to simulate darkness)
• Verify: light illuminates at expected brightness, all LED modules are working, no flickering
• Record the installation date, GPS coordinates, and pole number for maintenance tracking

Common Mistakes to Avoid

• Rushing foundation curing: Concrete needs 7 days to reach full strength. Installing too early causes leaning poles.
• Wrong panel orientation: Even a 30-degree error can reduce energy generation by 20%+.
• Ignoring shade: A single tree branch casting a shadow on the panel between 10 AM and 2 PM can cut output by 50%+.
• Overtightening bolts: Stripped threads are a costly repair. Use a torque wrench.
• No documentation: Without installation records, maintenance teams can't efficiently troubleshoot issues later.
