Can I Claim Depreciation on Solar Panels on My Rental?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can claim depreciation on solar panels installed on your rental property under **Division 40 of ITAA 1997**, as they are considered plant and equipment. The effective life is generally set by the ATO, allowing deductions over the asset's lifespan. Consult your accountant to ensure correct application.

Solar panels can be an excellent addition to your rental property, not only for their environmental benefits but also for their potential tax deductions. Under Division 40 of ITAA 1997, solar panels are classified as plant and equipment, making them eligible for depreciation. This means you can claim a deduction for the decline in value of these assets over their effective life, as determined by the ATO.

A common misconception is that solar panels fall under capital works and are depreciated over 40 years, similar to structural elements of a building under Division 43. However, solar panels are considered plant and equipment, typically depreciated over a shorter period, often around 20 years, depending on the specific details provided by the ATO.

To see how this plays out in practice, consider a scenario where you install solar panels worth $15,000 on a rental property in Melbourne. Assuming the ATO prescribes an effective life of 20 years, you can claim an annual depreciation deduction of $750. At a 37% marginal tax rate, this reduces your tax bill by $277.50 each year, enhancing your cash flow while supporting sustainable energy.

In our experience reviewing thousands of properties across Australia, investors often overlook the depreciation potential of solar panels. Many incorrectly assume these assets are part of capital works, leading to missed deductions. Furthermore, failing to update the property's depreciation schedule post-installation is a common oversight, as is not keeping detailed records of installation costs and dates, which are crucial for accurate claims.

The answer can differ depending on your situation. If the solar panels were installed after acquiring a second-hand residential property post-9 May 2017, you might not be eligible to claim Division 40 depreciation if the panels were previously used. However, if they were installed new after you purchased the property, you can claim. Similarly, if the property is owned by a company, different tax implications may apply.

When dealing with depreciation claims, it's essential to consult a Chartered Quantity Surveyor and your accountant. These professionals will ensure your claims align with current tax laws and maximise your potential deductions, considering all unique aspects of your property and ownership structure.

  • Check your property's current depreciation schedule.
  • Gather all documentation related to the purchase and installation of the solar panels.
  • Consult with a Chartered Quantity Surveyor to update your depreciation schedule.
  • Review your tax return with your accountant to ensure proper deductions.
  • Consider the environmental and financial benefits of solar panels for future property investments.
  • Stay informed about any changes in tax legislation that may affect your claims.
