Estimate my solar system

With so many solar panel brands claiming to be the most efficient, best value, or most advanced, picking one above the rest is no easy task. We lab test and review solar panels from major brands to help you choose.

Our solar panel reviews cover panels from major Australian and international brands. Our tests examine the manufacturing quality of the panels, and how well they match their claimed power output.

To see the specifications of current panels from major brands in the Australian market, check out our solar panel database.

Our expert testers test three samples of each solar panel to find the models that:

  • are closest to their labelled power output
  • demonstrate good manufacturing quality
  • are most efficient.

We also provide the panel's warranty details, which can be a good indication of the manufacturer's confidence in the product.

Note that there are no product images – most solar panels look very similar and appearance isn't a major factor when choosing them.

These tests are performed for CHOICE by PV Lab, an expert photovoltaics laboratory in Canberra, as our own lab doesn't have the required equipment or expertise.

Our solar panel buying guide will help you decide which type of panel is right for your home.

    Price per panel at time of testing. Actual prices can vary significantly between suppliers – you need to compare costs of whole systems and installation, not just the panels. NA = not available (some tested panels are not obtainable individually and were borrowed from suppliers).

    Monocrystalline: The typical black panel used in most current domestic installations. 

    Monocrystalline PERC: A higher efficiency technology found in some panels. See our buying guide for more information.

    Bifacial: Has solar cells on both faces, i.e. front and back. These can be mounted as usual, with the front facing the sky and the back face picking up extra reflected light from the roof, or mounted vertically (e.g. to face east and west for morning and afternoon sun).

      Claimed power output (W)

      Expand to view more details.

      The claimed power output for the panel under standard lab conditions. The higher the number, the more electricity you'll get from the panel. See our buying guide for an explanation.

      Product warranty

      Expand to view more details.

      The warranty for the panel itself, covering repair or replacement if the panel is faulty. 12 years is the typical minimum, but some brands have increased these warranties to 25 or 30 years (in some cases conditional on the panels being installed by one of their approved installers).
