5 Reasons Property Investors Are Going Solar
Property investors are always looking for an edge that sets a rental property apart from the rest of the market, and increasingly that edge is coming from the roof rather than the interior. Voltx energy has seen a steady rise in enquiries from landlords and investors who want to add solar and battery storage to their properties, not just for their own energy bills but as a genuine investment strategy. Here are five reasons why property investors across Australia are making the switch.
1. Tenants are actively seeking energy efficient homes
Rental demand has shifted noticeably in recent years, with tenants placing real weight on ongoing running costs rather than just weekly rent. A property with solar panels and a battery system installed offers a genuine point of difference in a competitive rental market, particularly as electricity prices continue to climb. Investors who list a property with solar and battery storage often report faster interest from prospective tenants, since the promise of lower power bills is an easy thing for a renter to understand and value.
2. Solar can add measurable value to a property
Beyond rental appeal, solar installations are increasingly recognised as adding to a property’s resale value. Research from Cotality on solar and home values found that homes with solar panels installed can command a meaningful premium compared to similar properties without them, reflecting a broader shift in how buyers weigh up ongoing costs when making a purchase decision. For an investor thinking beyond the current tenancy toward an eventual sale, this is a factor worth building into the numbers from the outset.
Vacancy periods are one of the most significant costs a property investor faces, often far outweighing the difference between a slightly higher or lower weekly rent.
3. Battery storage improves the economics of solar
A rooftop solar system alone only captures value while the sun is shining and the property is drawing power, which does not always align neatly with when a tenant is home and using electricity. Adding battery storage allows excess solar generation to be stored and used later in the day, improving self consumption and making the overall investment considerably more efficient. Wider industry research reinforces how much public perception has shifted on this point, with SolarQuotes reporting on how Australians view solar value noting that a large majority of Australians already believe solar adds value to a home, a view that only strengthens once battery storage is added to the equation.
4. Depreciation and tax benefits can offset the upfront cost
Investment properties come with a set of depreciation rules that owner occupied homes do not, and solar and battery equipment can often be depreciated over time as part of a broader capital works and plant and equipment schedule. While every investor’s situation is different and this is a matter to discuss with a qualified accountant, the ability to claim depreciation on a solar and battery system can meaningfully improve the return on investment compared to treating the cost purely as an out of pocket expense with no tax offset at all.
5. Lower running costs support stronger occupancy
Vacancy periods are one of the most significant costs a property investor faces, often far outweighing the difference between a slightly higher or lower weekly rent. Properties with lower running costs, including reduced electricity bills thanks to solar and battery storage, tend to hold tenant interest for longer and experience fewer vacancy gaps between leases. A tenant who is comfortable with their power costs and satisfied with the property overall is simply more likely to renew, which protects an investor’s rental income far more effectively than chasing a marginally higher rent with a less efficient property.
Weighing up the investment
None of this means solar and battery storage is the right call for every single investment property. Older properties with roofs nearing the end of their life, or properties in a portfolio destined for sale in the near term, may not be the best candidates for a full system installation right now. But for investors holding properties for the medium to long term, particularly in a portfolio built around rental yield and tenant retention, the combination of tenant appeal, added property value, improved solar economics through storage, potential tax benefits and stronger occupancy makes a compelling case.
Getting the numbers right before you commit
As with any investment decision, the details matter more than the headline appeal. Get a proper quote based on the specific property, including roof orientation, shading and the electricity usage pattern typical of the kind of tenant the property attracts. Compare the upfront cost against likely rental premium and occupancy improvements over a realistic holding period, rather than assuming every property in a portfolio will see the same return. For many investors, starting with one property as a test case, rather than converting an entire portfolio at once, is a sensible way to build confidence in the numbers before expanding further.
Final thoughts
Solar and battery storage has moved from a niche upgrade to a genuine consideration in property investment strategy, driven by tenant demand, measurable value gains and improved long term economics once storage is added to the mix. Investors who take the time to run the numbers properly, rather than following the trend blindly, are finding that a well specified solar and battery system can be one of the more straightforward ways to strengthen both the appeal and the performance of a rental property.
