Solar Myths Busted: What You Really Need to Know

Posted by Signature Solar on 19th Sep 2025

Separating Fact from Fiction in the World of Solar Energy

As solar energy becomes more popular, myths and misconceptions still linger. At Signature Solar, we believe in helping customers make informed choices. That starts with busting the most common myths surrounding solar panels and energy systems.


Myth #1: Solar Panels Are Heavy and Damage Roofs

Fact: Today’s solar panels are designed to be both lightweight and roof-friendly. Most residential panels weigh around 40 pounds and are spread across mounting systems that distribute weight evenly, minimizing stress on your roof. When installed properly by professionals or even well-guided DIYers–solar panels don't damage your roof. In fact, they often act as a protective barrier against harsh weather conditions like hail, UV rays, and rain, which can actually help preserve the underlying roof materials.

Properly installed solar panels are lightweight and secure–posing no risk to your roof. In fact, they can help shield shingles from the elements and extend the life of your roofing materials.


Myth #2: Solar Energy Isn’t Reliable

Fact: Solar energy systems are dependable, especially when combined with battery storage solutions. Batteries store excess energy generated during the day and release it when needed, such as at night or during cloudy weather. With advancements in lithium-ion battery technology and smart inverters, solar systems can now provide seamless, consistent power for homes and businesses alike. For remote locations or off-grid lifestyles, solar is often the most reliable option available.

Myth #3: Solar Energy Only Work When the Sun is Out

Fact: While solar panels are most productive in full sunlight, they can still generate electricity on cloudy or overcast days by capturing diffused sunlight that’s scattered by the atmosphere. They won’t operate at full capacity, but most systems continue to generate a significant portion of their rated output. Modern panels are more efficient than ever and are designed to maximize energy harvest in a wide range of weather conditions. For even greater consistency, pairing panels with battery storage ensures you have power when you need it; rain or shine.

Myth #4: All Solar Panels Look the Same

Fact: There’s more variety in solar design today than ever before. From sleek black monocrystalline panels with all-black racking systems to lower-profile panels that blend into your roofline, homeowners have aesthetic choices. Some brands even offer frameless panels or building-integrated solar (BIPV) that look like roof shingles. Whether you’re concerned about curb appeal or matching your roof type, there are solutions that fit both function and form.

Myth #5: Solar Panels Need Frequent Maintenance

Fact: Solar panels are built to last, with minimal upkeep. The typical system only requires periodic cleaning to remove dust, pollen, bird droppings, or leaves that might block sunlight. Most manufacturers recommend cleaning a couple of times a year–less if you live in an area with regular rainfall. Modern panels also come with long-term warranties (often 25 years or more), and with no moving parts, there's little risk of mechanical failure. Monitoring systems can alert you if something needs attention, making solar ownership easy and low-maintenance.

Myth #6: Solar Energy is Too Expensive

Fact: Solar energy is more affordable than ever. Over the last decade, the average cost of solar installations has dropped by more than 70%, and panels themselves have seen a 30% price reduction in just the past few years. Additionally, federal tax incentives (like the 30% Investment Tax Credit), state rebates, and local financing programs can make the upfront investment much more manageable. Over time, homeowners can see significant savings on their energy bills–often paying off their system in 5 to 10 years and enjoying free power for decades afterward.

Myth #7: Solar Will Keep My Lights On During a Power Outage

Fact: Most grid-tied solar systems automatically shut down during power outages to protect utility workers who may be repairing electrical lines. This safety mechanism is required by law. However, with the addition of battery storage systems or hybrid inverters that support backup power, your system can keep essential circuits running during an outage. More and more homeowners are choosing to add batteries specifically for this reason, to gain energy independence and peace of mind during grid failures.
