Solar energy is reshaping how Australians power their homes, but despite its popularity, a lot of myths still hang around. Some of these misconceptions come from outdated information, others from misunderstanding how solar works. Either way, myths can cause hesitation for homeowners who might otherwise benefit.
Let’s break down some of the most common solar myths, and uncover the facts that really matter when deciding if solar is right for you.
Fact: Solar panels don’t need scorching sunshine to generate electricity, they work whenever there’s daylight. Panels use photons from sunlight, not heat, to create power.
Even on cloudy or rainy days, solar panels can still produce between 10–25% of their maximum output. In fact, cooler temperatures can improve efficiency because extreme heat actually reduces panel performance. Germany, which has far fewer sunny days than Australia, has been a global leader in solar adoption for decades. Proof that overcast skies don’t stop solar from working.
Fact: While the upfront price of solar used to be a major barrier, costs have plummeted in the last decade. According to the International Renewable Energy Agency (IRENA), the average cost of solar modules has dropped by more than 80% since 2010, making solar one of the most affordable forms of new electricity generation worldwide (IRENA, 2024).
On top of that, Australians benefit from generous government incentives:
• The Small-scale Renewable Energy Scheme (SRES) offers tradable certificates that reduce upfront costs.
• Many states and territories, including NSW, provide additional rebates or zero-interest loans for solar and batteries.
With these incentives, a typical solar system can pay itself off in 3–6 years, depending on household energy use. After that, it’s largely free electricity for the remaining life of the panels, often 20 years or more.
Fact: One of the biggest advantages of solar panels is how little upkeep they need. With no moving parts, panels are durable and built to withstand rain, wind, and heat.
For most homeowners, maintenance involves:
• A yearly inspection by a qualified installer to check electrical systems.
• Occasional cleaning if panels get dusty, especially in dry or coastal areas.
Many manufacturers back their products with 25-year performance warranties, reflecting their reliability. For comparison, this makes them one of the lowest-maintenance investments you can put on your property (Accredited Power).
Fact: This one is partly true. A standard grid-connected system automatically shuts off during blackouts to protect line workers. But if you add a battery system or a specially designed hybrid inverter, your solar setup can keep running even when the grid goes down.
Modern battery systems, like the Tesla Powerwall or Sonnen batteries, can keep essential household appliances powered — from fridges to Wi-Fi routers, until the grid is restored. For households in bushfire-prone or storm-affected regions, this backup function is one of the biggest benefits of pairing solar with a battery (Clean Energy Council).
Fact: Solar panels are a clean energy source and have a far smaller carbon footprint than fossil fuels. Over their lifetime, panels typically generate 20–30 times more energy than it takes to manufacture them.
Another misconception is that solar panels can’t be recycled. In reality, Australia is implementing several programs and policies to manage end-of-life panels responsibly. For example, the Clean Energy Council provides guidance on recycling and reuse options. The NSW Government is rolling out a national solar panel reuse and recycling scheme, and research by APVI/UNSW highlights the enormous potential value of recovered materials.
Glass, silicon, and metals from old panels can now be recovered and reused, helping reduce waste and support a circular economy. Solar energy isn’t just good for household budgets it’s one of the cleanest ways to reduce greenhouse gas emissions while contributing to sustainable resource use.
Fact: When installed properly by accredited professionals, solar panels do not damage your roof they can actually protect it. Panels cover parts of the roof, shielding them from sun, rain, and hail. Mounting systems are designed to integrate securely with common roofing materials like tiles, Colorbond, and corrugated iron.
In many cases, panels can extend the life of your roof underneath them by reducing direct weather exposure. As long as installation is carried out by an installer accredited by Solar Accreditation Australia (SAA), your roof warranty and integrity remain safe.
Fact: Contrary to this myth, solar panels can significantly increase your property’s value. According to a Domain article, homes with solar installations have been shown to sell for higher prices and more quickly compared to similar homes without solar.
Buyers recognise the long-term savings on energy bills, greater energy independence, and the environmental benefits of solar energy. With rising electricity costs, installing solar panels not only enhances your home’s appeal but also positions it as a forward-thinking investment that attracts future buyers.
Solar energy isn’t just about cutting electricity bills, it’s a proven, reliable, and environmentally friendly technology that’s helping millions of Australians move toward energy independence.
By separating fact from fiction, homeowners can see that solar panels are affordable, low-maintenance, and future-proof. With government incentives, growing battery options, and strong recycling programs, there’s never been a better time to take the step toward solar.
