Over the past few decades, solar technology has advanced immensely, and the misconceptions surrounding it continue to prevent many from making the switch. In this guide, we’ll bust the 12 most common solar power myths, replacing fiction with facts that will leave you seeing solar in a whole new light.

Solar energy is an essential part of our future, and breaking through the myths is crucial for wider adoption. The sun is one of our most abundant and untapped resources, and we have the technology to harness it like never before. Let’s dive into these myths, set the record straight, and show how you can benefit from solar energy.

Myth 1: Solar Panels Only Work in Sunny Climates

This is one of the most common solar power myths. While it’s true that solar panels perform best in direct sunlight, they can still generate electricity in cloudy, rainy, and even snowy weather. In fact, solar panels can work efficiently even in conditions where direct sunlight isn't available.

Countries like Germany and the UK—hardly known for endless sunshine—have invested heavily in solar energy systems and seen strong returns. In fact, Germany is one of the largest producers of solar power in Europe, despite its less-than-ideal weather conditions. The reality is that solar energy systems are designed to capture a wide range of sunlight, meaning they can still work in overcast and inclement weather.

In some places, snow can even improve solar panel efficiency by reflecting light onto them. Solar panels don’t need constant sunshine—they only need light, and they’ll produce energy for your home or business no matter the weather.

Myth 2: Solar Energy is Too Expensive

A decade ago, this was true. But today, the cost of solar panels has dropped more than 70%, making them more accessible than ever. The federal Investment Tax Credit (ITC) also offers a 30% tax credit for new solar installations, significantly reducing upfront costs for homeowners. On top of that, financing options, grants, and rebates are more widely available, making solar energy accessible for homeowners across different income brackets.

With rising electricity costs and growing interest in clean energy solutions, more and more people are realizing that investing in solar power is not just an environmentally responsible decision—it’s also financially savvy. The cost of installing solar panels has become much more manageable, and many homeowners can see a return on investment in as little as 5–7 years.

Myth 3: Solar Panels Require High Maintenance

Another big myth. In reality, most solar panel systems need minimal maintenance beyond occasional cleaning and annual inspections. Solar systems are designed to be robust and long-lasting, with no moving parts that require constant attention. In fact, modern solar panels can last 25 years or more, with many manufacturers providing 25-year warranties on their performance.

Unless your area is hit by extreme weather or heavy dust, your solar panels should run smoothly for decades. Regular cleaning to remove dirt and debris is typically all that’s needed, and most panels are self-cleaning in areas that receive regular rainfall. For the vast majority of homeowners, solar panels are incredibly low-maintenance systems.

Myth 4: Solar Panels Damage Roofs

Quality solar panel installations are designed to protect your roof, not harm it. Installers use proper sealing methods to prevent leaks or structural issues, ensuring that your roof remains intact and fully functional. This is a concern many potential solar adopters have, but it's important to note that a solar panel installation is typically much less invasive than many other types of home improvement projects.

In fact, the area under solar panels is shielded from the sun, rain, and snow—helping to extend the life of your roofing materials. With professional installation by certified experts, your roof is safe and secure, and in many cases, solar panels can add value to your home by offering long-term protection for your roof.

Myth 5: Solar Panels Can’t Function During Power Outages

This myth confuses grid-tied systems with total solar functionality. While standard systems shut down during an outage for safety reasons, pairing them with battery storage provides backup power for your home. Many homeowners today choose to integrate solar batteries into their systems, allowing them to store excess energy for use when the electricity grid goes down.

With battery storage systems, you can keep lights, refrigerators, and critical appliances running even when the grid is down. This added security makes solar energy even more appealing, especially in areas prone to frequent power outages. So, while grid-tied systems may not provide backup power on their own, solar energy storage is a fantastic solution.

Myth 6: Solar Energy is Not Very Efficient

Older panels might have struggled with efficiency, but that’s no longer the case. Newer models can reach up to 22% efficiency, compared to the 15–18% range of the past. Technological advancements in solar cell technology have significantly improved efficiency, meaning more power can be generated from the same amount of sunlight.

Even though no panel will capture 100% of the energy from the sun, the fact remains that solar power is one of the most effective and cleanest ways to generate energy. And don’t forget—sunlight is free and abundant. Even if a solar panel only captures a portion of the available sunlight, it can still dramatically reduce energy bills and your reliance on grid power.

Myth 7: Solar Panels Have a Negative Environmental Impact

While no energy source is entirely impact-free, solar energy is one of the cleanest forms of power we have. Yes, the production of solar panels consumes resources and energy, but over their lifetime, solar panels drastically reduce carbon emissions and help move us toward a carbon-neutral future. After installation, solar panels generate zero emissions and require minimal maintenance.

In the long term, the environmental benefits far outweigh the initial production footprint. Additionally, many manufacturers are investing in sustainable practices for producing solar panels, using recycled materials, and creating more efficient recycling processes.

Myth 8: Solar Technology Isn’t Improving

On the contrary, solar panel technology is advancing rapidly. We’ve already seen significant gains in efficiency, lifespan, and design. Today’s panels are more durable, lighter, and better adapted to various roof types and climates. The innovation in solar shingles and solar tiles has made it easier for homeowners to adopt solar without disrupting the aesthetics of their homes.

The growth of solar battery storage technology has also expanded the versatility of solar energy, giving consumers more control over how and when they use the energy they generate. Innovations like perovskite solar cells and transparent solar panels are opening new doors for the future of solar power.

Myth 9: Solar Panels Diminish Property Value

Actually, it’s quite the opposite. According to Zillow, homes with solar panels sell for 4% more on average than homes without. The Lawrence Berkeley National Laboratory also found that homes with solar sold for $15,000 more than non-solar homes. In many cases, potential buyers are actively looking for homes with solar panels due to the promise of lower energy bills and the home’s eco-friendly credentials.

Far from hurting the value of your home, solar panels can be a major selling point, especially as more buyers prioritize sustainability and cost savings. Installing solar can give your property an edge in a competitive market.

Myth 10: Solar Energy is a Passing Fad

Solar energy has been around for decades—and it's only getting bigger. As more countries invest in renewable energy sources, solar is now a core part of long-term climate and energy plans. From private homes to commercial properties, solar power is becoming more widespread and economically viable.

With prices continuing to drop and government incentives still available, solar energy is becoming an essential part of the energy landscape. The solar industry continues to create jobs, drive innovation, and help us transition toward a cleaner, more sustainable future. It’s here to stay.

Myth 11: Solar Power Is Ineffective in Cold Weather

Cold doesn’t mean ineffective. In fact, solar panels often work better in cooler temps, since high heat can actually reduce efficiency. What matters more is the amount of sunlight—not the temperature. Solar panels are designed to perform optimally in a range of temperatures, and in many places, the cooler weather helps prevent overheating and maintains performance.

In cold climates like Minnesota or Canada, solar energy is just as viable as in warmer regions. Snow can even reflect sunlight onto solar panels, boosting efficiency in some cases.

Myth 12: Solar Cannot Cushion Electricity Bills

Another myth bites the dust. The whole point of going solar is to reduce electricity bills by generating your own clean energy. With net metering, homeowners can send excess energy back to the grid and receive credits, helping them offset periods when their solar panels aren’t generating power (e.g., at night).

In the long run, this can lead to huge savings on energy costs, and depending on the region, it can even help homeowners earn a return on their solar investment. Many people find that after a few years, their solar installation pays for itself, with a considerable reduction in monthly energy expenses.
