Will my solar street lights fail? 5 signs your solar lights can be trusted

We understand you can’t take any risks when it comes to solar street lights. If your project or site needs constant lighting, in every weather condition or for personal safety issues, you need to trust your solar street lights are high quality, reliable and fit for purpose.

There are several factors that contribute to reliable and constant solar lighting.

Here’s five telltale signs you can trust your solar street lights will stand the test of time and perform reliably for mission critical lighting projects.


1. Your solar lighting systems comply with Australian and New Zealand Standards

To meet Australian and New Zealand standards your solar lighting systems must comply with the following standards:

  • AS/NZS 3000 Electrical Installations
  • AS/NZS 4509 Stand-Alone Solar Power Systems Design
  • AS/NZS 5033 Installation and Safety Requirements for Photovoltaic (PV) arrays
  • AS/NZS 5139 Safety of Battery Systems for use with Power Conversion Equipment


2. Your solar lighting system has the correct size battery and solar panel for your lighting requirements and location

The calculation for determining battery and solar panel size needs to include:

  • sophisticated weather and solar radiation data for the specific location;
  • a specialised system sizing tool that uses inputs such as peak sunlight hours, night-time length, average and worst-case consecutive ‘dark out days’, as well as the necessary de-rates for performance degradation; and
  • the ‘power in equals power out’ rule.

You can ask your solar lighting supplier to show you how they calculate the correct size battery and solar panel.


3. A shading assessment has been completed

A shading assessment ensures your solar panels receive direct sunlight all day all year round, or the necessary de-rates are allowed for if the solar panel is subject to some shade.


4. Your solar lights come from a reputable supplier

You can trust your solar lighting supplier has been vetted if they’re a Local Government Procurement (LGP) or Localbuy preferred supplier.

Other markers can include a history of successful work (case studies) and referrals from people and companies you trust.


5. Your solar lights are backed by strong product warranties and performance guarantees

Talk to your supplier about what performance guarantees and warranties are provided with your solar lighting systems.
