Debunking 4 Common Solar Power Myths

Solar energy is transforming the way we power our businesses, rapidly becoming a cornerstone of clean, reliable energy worldwide. But despite its growing adoption, a number of persistent myths still hold people back from making the switch. Whether you're a business owner weighing the benefits or simply curious about renewable energy, it's time to separate fact from fiction. Let’s shed light on four of the most common solar power myths.

Myth 1: Solar Panels Don’t Work on Cloudy Days

A common misconception is that solar panels only work under direct sunlight. While it’s true that solar panels perform best in clear conditions, they still generate electricity on cloudy days. That’s because they rely on visible light, which can penetrate cloud cover.

“Solar panels can still produce electricity on cloudy days—just at a lower output,” explains Spencer Fields of EnergySage.

Rain can even be beneficial by washing away dust and debris, improving panel efficiency. In fact, Germany—despite its often overcast climate—is one of the world’s top solar power producers, proving that sunny skies aren't a requirement for solar success.

Myth 2:  Solar Energy Is Too Expensive

The idea that solar power is unaffordable is increasingly outdated. Over the past decade, the cost of installing solar panels has fallen dramatically by over 40% globally.

In Africa, the price drop has been even more impressive. According to the International Renewable Energy Agency (IRENA), the installed cost for utility-scale solar PV projects has decreased by up to 61% since 2012, with prices as low as USD 1 per watt, well below the global average of USD 1.80 per watt.

Off-grid systems tell a similar story. Solar home kits can now meet a household’s annual electricity needs for as little as USD 56 per year, which is often less than what many families spend on traditional fuels like kerosene.

For commercial and industrial (C&I) users, flexible financing options make solar adoption easier and more strategic. Options include Power Purchase Agreements, leases, and Energy-as-a-Service, which allow them to adopt solar with minimal upfront investment while paying only for the power they use. For those seeking long-term savings and asset control, outright purchase (CapEx) remains a strong option, often with added tax and depreciation benefits.

Myth 3: Solar Panels Aren’t Recyclable

Concerns about what happens to solar panels at the end of their lifespan are understandable, but the idea that they can’t be recycled simply isn’t true. Most solar panels are made of highly recyclable materials, including glass, aluminum, and silicon.

“Solar panels are not toxic and are recyclable at the end of life,” affirms the Solar Energy Industries Association (SEIA).

With proper processing, 80–95% of a panel’s components can be recovered and reused. Countries like France and Japan already operate large-scale solar recycling programs, and infrastructure is quickly expanding in other regions, including the United States.

Myth 4: Solar Is Only for Homeowners

While solar adoption among homeowners gets a lot of attention, it’s just as—if not more—valuable for businesses. The idea that solar is only for residential use doesn’t hold up.

Commercial solar installations can significantly reduce operating costs, especially in areas with high electricity prices or unreliable power supply.

“Solar is an investment that pays for itself—and then some,” notes IRENA. “Businesses can often see returns in under five years through savings alone.”

Businesses also benefit from improved energy independence and reduced risk during outages—an especially important factor in many parts of Africa. Plus, going solar supports ESG (Environmental, Social, and Governance) goals, helping companies boost their sustainability credentials and appeal to environmentally conscious customers and investors.

Ownership options like outright purchases, leases, and Power Purchase Agreements (PPAs) make solar accessible for businesses of all sizes—whether you're running a manufacturing plant, a hotel, or a chain of retail stores.

Final Thoughts

Solar power isn’t just clean—it’s practical, reliable, and more affordable than ever. By debunking these common myths, we hope to empower more individuals and businesses to explore the benefits of solar energy. The sun is one of our most abundant resources—let’s make the most of it.
