Commercial Car Park Lighting Retrofit: Solar Solutions

Upgrade your car park lighting without trenching or business disruption. Learn how solar area lights deliver AS/NZS compliant illumination with zero electricity costs.

Well-Lit Car Parks Build Customer Confidence

Quality lighting transforms a car park from a utilitarian space into one that signals professionalism and care. Customers feel more comfortable returning to well-lit properties, especially after dark.

The Australian Institute of Criminology's research on Crime Prevention Through Environmental Design (CPTED) identifies lighting as a key element of creating welcoming, well-managed spaces. Proper illumination signals active property management.

For commercial property owners, the challenge is balancing lighting improvements against operational disruption and cost. Traditional electrical lighting retrofits can shut down portions of a car park for weeks.

The Traditional Retrofit Challenge

Trenching Disruption

Digging up asphalt or concrete to lay cables disrupts business operations and parking availability for weeks.

Capital Costs

Electrical infrastructure can be a major cost once trenching, materials, and reinstatement are included.

Council Approvals

Electrical work often requires development applications, engineering certification, and compliance inspections.

Ongoing Costs

Metered electricity, maintenance contracts, and globe replacements add up to thousands annually.

Why Solar Works for Car Parks

Install in Days, Not Months

Solar area lights mount on existing poles or new ground-spike poles without trenching. Installation time depends on site access and layout.

Zero Electricity Costs

Solar panels charge batteries during the day, providing free illumination all night. No metered electricity, no bill increases.

Crime Deterrent

Well-lit car parks deter opportunistic theft and break-ins. Visible lighting signals an actively managed property.

Liability Protection

Adequate lighting helps demonstrate duty of care. Dark car parks expose property owners to negligence claims for incidents.

Car Park Lighting Guide (AS/NZS 1158)

AS/NZS 1158 provides guidance for road and public space lighting. While specific requirements vary by jurisdiction, these are typical recommendations:

AreaLux LevelRecommendation
Entry/Exit Points20-50 luxHigher visibility for vehicles and pedestrians entering/exiting.
Driving Lanes10-20 luxTypical guidance for safe vehicle navigation and uniformity.
Parking Bays5-10 luxTypical guidance for pedestrian safety in bays.
Pedestrian Paths10-20 luxTypical guidance for safe navigation and trip hazards.
Stairwells/Ramps50-100 luxHigher levels are often used for steps and ramps.

Implementation Checklist

1
Audit existing lighting
Measure current lux levels at different points to identify gaps and compliance issues.
2
Map solar exposure
Identify optimal mounting locations with unobstructed sunlight for 4-6 hours daily.
3
Calculate spacing
Use manufacturer photometric data and on-site lux measurements to set spacing for uniform coverage.
4
Plan installation timing
Schedule during low-traffic periods to minimise disruption.
5
Document compliance
Photograph installed lighting and record lux levels for liability protection.

Key Takeaways

  • Well-lit car parks enhance customer confidence and property value
  • Traditional retrofits can require trenching, approvals, and substantial civil works
  • Solar area lights can install faster without electrical infrastructure
  • Lighting guidance commonly targets 5-10 lux for bays and 10-20 lux for lanes
  • Proper lighting helps demonstrate duty of care for liability protection
  • Coverage and spacing should be based on measured lux, not lumens alone
