Debunking Myths About Solar: Separating Fact from Fiction

Solar energy is one of the most talked-about topics within the renewables space, and yet plenty of rumours and myths still surround it. Adages like “Solar doesn’t work on cloudy days” or “it’s too expensive to be worthwhile ” are a plenty.
With so much conflicting information out there, it’s no wonder there is confusion. Let’s break down some of the most common solar myths and get to the truth, providing clarity once and for all.
Myth 1: Solar Panels Don’t Work on Cloudy or Rainy Days
The Truth: Solar panels work even when the sun isn’t shining at full strength.
One of the biggest misconceptions about solar energy is that it only works when the sky is clear and the sun is beaming down. While it’s true that solar panels generate the most power on bright, sunny days, they still produce electricity on cloudy, rainy, or even foggy days. In fact, countries with significantly less sunshine than our Australia—such as Germany and the UK—boast thriving solar industries. Modern solar panels are designed to absorb diffused sunlight, meaning they can still generate power even when the sky is overcast.
Added bonus: occasional rain actually helps keep your solar panels clean, washing away dust and debris that could otherwise reduce efficiency!
Myth 2: Solar Power Is Too Expensive
The Truth: Solar is more affordable than ever. It pays for itself.
Solar systems were indeed pretty pricey when they first hit the market. However, as with all popular products, the market is now flooded with many great product options, meaning prices have had to drop dramatically to keep up. Then there are the Government incentives and rebates, reducing the upfront cost further. And the ability to sell excess power generated back to electricity companies, creating credits in place of bills.
Think of solar panels as a long-term money-saving tool. A financial investment. Yes, there’s an upfront cost, but reducing your electricity bills means the system eventually pays for itself—and then some. You’ll be pleasantly surprised how quickly you start seeing and feeling the savings
Plus, with rising electricity prices, locking in free power from the sun is a smart move for the future.
Myth 3: Solar Panels Require Too Much Maintenance
The Truth: Solar panels are incredibly low maintenance.
Unlike many so many of your other home investments like appliances, solar panels don’t have moving parts, so very little can go wrong. Most systems require minimal upkeep—just a simple clean a few times a year to remove dust, leaves, and bird droppings. In most cases, rainfall will take care of most of the cleaning for you. If you live in an area with lots of dust or pollen, an occasional rinse with a hose (or hiring a professional cleaner) is enough to keep your system running efficiently.
Beyond that, a quick professional check-up once a year will ensure everything is still running in optimal condition. First Choice Solar provides ongoing support and maintenance services to give you that peace of mind.
Myth 4: Solar Will Let You Go Completely Off-Grid
The Truth: Most solar homes remain connected to the grid—unless they have batteries.
Many people are led to believe that installing solar panels automatically means that you can disconnect from the grid (electricity companies) entirely. But in reality most solar systems are grid-tied, meaning they work with the electricity grid rather than replacing it. Solar panels generate power during the day, but most households use electricity at night, meaning the need for top up electricity remains. That being said, solar battery storage is becoming more popular and affordable. If you’re looking for more energy independence, a battery system can help store excess solar energy, allowing you to use it at night and reduce reliance on the grid even further.
Myth 5: Solar Panels Will Damage My Roof
The Truth: Solar panels protect your roof and can even extend its lifespan.
Some homeowners worry that installing solar panels will lead to roof leaks or structural issues. Meaning more cost, most stress. However, when installed correctly by professionals (like our team at First Choice Solar), solar panels actually help protect your roof from the elements. They shield the areas beneath them from sun exposure, rain, and harsh weather, which can extend the life of your roof. And the proper installation ensures that the mounting points are secure and watertight, eliminating any risk of leaks.
A good solar company will let you know if your roof needs repairs before installation, ensuring your system is installed on a solid, durable surface.
Myth 6: Solar Panels Don’t Last Very Long
The Truth: Solar panels can last 25 years or more.
Solar panels are built to last. Most high-quality solar panels come with 25-year performance warranties, but many continue generating electricity well beyond that. While efficiency may decline slightly over time, properly maintained panels can keep producing power for decades. The key is to choose a reputable brand and work with an experienced installer. First Choice Solar only use trusted, high-performance panels designed to withstand Australia’s tough climate.
