Solar Mythbusters
(5 Common Misconceptions about Solar Energy)

Here are the 5 Common Solar Energy Myths - BUSTED! 

1. MYTH: Solar energy lacks sufficient power to sustain a home. 

FACT: The myth that solar energy is insufficient to power homes is outdated. Thanks to continuous technological advancements and improved energy storage solutions, solar panels can efficiently supply power to residential homes and commercial establishments [1].

2. MYTH: Solar panels are too expensive.

FACT: Solar panels might initially seem expensive, but their long-term benefits outweigh the initial installation costs. By harnessing solar energy, individuals can enjoy reduced electricity bills and even take advantage of potential government incentives, making it a financially savvy investment [2].

3. MYTH: Solar panels can’t work on cloudy days.

FACT: Contrary to the myth, solar panels are not limited to sunny days; they can still generate considerable energy during cloudy or winter days. The efficiency may vary slightly based on panel quality, but photovoltaic solar panels have the ability to convert both direct sunlight (Direct Normal Irradiance - DNI) and reflected light (Diffused Horizontal Irradiance - DHI) into electricity, enabling power generation even in less direct sunlight conditions [3].

4. MYTH: Solar panels demand costly maintenance.

FACT: The reality is that maintaining solar panels isn't as costly as commonly believed. These systems are designed to endure various weather conditions and have a long lifespan, spanning decades. Like any technology, they require periodic maintenance, but it's generally straightforward. In most cases, routine cleaning is sufficient to ensure no obstructions blocking sunlight. If there are no overhanging trees or you reside in regions without typhoons, yearly inspections are typically enough [4].

5. MYTH: Solar panels pose long-term environmental harm after decommissioning.

FACT: Disposing solar panels doesn't have to be harmful to the environment in the long run. These panels can last for 25 years or more, and once they reach the end of their lifespan, they can be recycled. Solar panels are constructed using highly recyclable materials such as glass, aluminum, and plastic, significantly reducing environmental impact. Many manufacturers offer recycling options for solar power systems [5].
