Top 10 Solar Panel Myths

In a world increasingly conscious of its environmental footprint, solar energy stands at the forefront of sustainable solutions, challenging longstanding myths with robust facts. From their ability to thrive in cold, snowy, or cloudy conditions to their economic viability, solar panels defy the misconceptions that have long clouded their potential. This blog post illuminates the truth behind ten prevalent solar panel myths, from the ease and affordability of installation to the environmental and financial benefits they bring. Whether addressing concerns about grid connectivity during power outages, the supposed complexity of solar system maintenance, or the impact of solar installations on property values and roof integrity, we unravel the facts. Furthermore, we tackle the comparison with "clean coal" and address the environmental considerations post-lifecycle of solar panels. Join us as we shed light on the realities of solar power, debunking myths and setting the record straight for a brighter, greener future.

Top 10 Solar Panel Myths

Myth 1: Solar panels do not work in cold snowy weather or when it is cloudy

Fact: Solar panels are versatile, functioning optimally in a variety of conditions including sunny, cold, and cloudy environments. The technology underpinning solar panels enables them to operate efficiently across these varied climates. Interestingly, solar panels often perform better in cooler temperatures than in warmer ones. Moreover, the presence of clouds does not significantly detract from their efficiency; solar panels remain a reliable source of electricity, capable of producing sufficient power even under overcast skies. Additionally, on cold but sunny winter days, these panels can generate electricity levels comparable to those of hot summer days. Notably, countries like Germany, which leads the world in solar panel deployment, along with the UK, China, and Italy, have demonstrated the effectiveness of solar systems in diverse climatic conditions.

Myth 2: Solar energy can still power my home when the power goes out

Fact: When residing in a grid-connected environment, power outages necessitate shutting down the grid system to ensure the safety of electrical workers repairing the lines. Consequently, your inverter is designed to detect when the grid is offline and will automatically cease electricity production from solar panels to prevent the risk of sending power back into the grid during maintenance.

Myth 3: Solar energy is too costly and is not economically viable

Fact: An examination of data from 2009 to 2015 reveals a consistent upward trend in solar panel investments, attributed largely to their increasing affordability. During this period, the average costs of solar panels have decreased by approximately 30%. On a global scale, the cost of generating electricity from solar energy has become more economical than producing it from coal.

Myth 4: Installing solar is quite complicated and requires a lot of maintenance

Fact: The process of installing solar panels is relatively straightforward, especially when engaging a reputable manufacturer. Commonly, solar energy systems are integrated with the utility grid, which simplifies maintenance. To ensure optimal performance, solar panels require only basic cleaning with water to remove dust, debris, or snow accumulations. These panels are designed to endure severe weather conditions, such as hail and sleet, due to their robust construction. While systems equipped with batteries may necessitate more frequent cleaning, the majority of installations do not include batteries, making them not only more common but also more cost-effective compared to systems with battery storage.

Myth 5: Solar panels can cause damage to your roof

Fact: Solar panels confer a protective advantage to the area of the roof they occupy, aiding in its preservation. Should the underlying roof require repairs due to damage, the panels can be readily detached. This ease of removal is due to the panels not being directly affixed to the roof's surface but rather mounted atop it. To address any spaces that might exist between the rooftop and the panels, sealant is applied to ensure a tight fit. Furthermore, the mounting hardware is safeguarded by metal "flashing" or coverings, offering an additional layer of protection. It is essential to verify that your roof is in pristine condition prior to installing a new rooftop solar system.

Myth 6: Excess energy can be stored in battery systems

Fact: Residing in a grid-connected environment means your solar system interfaces with the public electricity grid, making you eligible for net metering benefits. This arrangement allows you to retain your existing local utility provider. On days when your system produces surplus electricity, the excess is credited to your account. Consequently, during periods such as nighttime when solar production ceases, you can draw upon this credited power to meet your needs, directly from the grid. This process is seamless, with no perceptible transitions, ensuring consistent electricity supply while maintaining lower utility bills.

Myth 7: Reselling your home will be harder with solar panels

Fact: Solar panel installations are known to augment the market value of homes. Research consistently shows that properties equipped with solar panels tend to sell more swiftly than those without. While the initial investment for solar panels may range between £5,000 and £8,000, the potential increase in property value can average around £14,000, although the exact uplift is contingent on various factors.

Myth 8: Solar panel prices are based on the size of your home

Fact: Solar panels are tailored to meet the unique requirements of each homeowner. The process of calculating the installation cost for solar panels involves careful consideration of your home's roof orientation and slope. Furthermore, the installation takes into account the roof's surrounding environment to ensure the panels are sited in locations with optimal sunlight exposure, free from obstructions such as nearby trees or buildings.

Myth 9: If we can use clean coal, why invest in solar energy?

Fact: Solar power represents a significantly cleaner energy source compared to "clean coal," which, despite its name, is far from clean. Coal stands as one of the most polluting fossil fuels, with coal mining activities, including mountaintop removal and the creation of toxic slurry ponds, causing widespread health issues. The combustion of coal contributes to severe environmental degradation, elevating levels of mercury, smog, and carbon pollution. This escalation in pollutants not only harms the environment but also exacerbates the effects of climate change, making a strong case for the adoption of cleaner, renewable energy sources like solar power.

Myth 10: Solar panels are bad for the environment after their lifetime is used up

Fact: Solar panels are engineered to achieve an optimal lifespan of up to 25 years, after which they are suitable for recycling. The feasibility of recycling depends on the manufacturer chosen for the solar panel installation. While many panels continue to function effectively beyond their expected lifespan, making it challenging to determine the extent of recycling, certain manufacturers offer recycling services at no additional cost.


In conclusion, dispelling the myths surrounding solar energy is crucial for advancing towards a more sustainable and environmentally friendly future. By understanding the realities of solar panel performance, cost-effectiveness, maintenance, property value, and environmental impact, we can embrace solar energy with confidence. This knowledge empowers homeowners and businesses alike to make informed decisions, contributing to the global effort against climate change. As we move forward, let us lean into the facts, recognising solar power not just as a viable option, but as a cornerstone of our collective move towards clean, renewable energy.
