Most people choose crystalline silicon solar panels over amorphous silicon solar panels for several reasons.
- Efficiency: Crystalline silicon solar panels generally have higher efficiency compared to amorphous silicon panels. Efficiency refers to the percentage of sunlight that can be converted into electricity. Crystalline silicon panels typically have efficiencies in the range of 15% to 20% or more, while amorphous silicon panels typically have efficiencies of 5% to 10%. Higher efficiency means that crystalline silicon panels can generate more electricity for the same amount of sunlight.
- Longevity: Crystalline silicon panels tend to have a longer lifespan compared to amorphous silicon panels. Crystalline silicon panels can last 25 years or more, whereas amorphous silicon panels may have a shorter lifespan, typically around 10-15 years. This longer lifespan makes crystalline silicon panels a more reliable and cost-effective choice over the long term.
- Performance in Low Light Conditions: Crystalline silicon panels also perform better in low light conditions, such as cloudy days or early morning and late afternoon hours. They can generate some electricity even when there is less sunlight available, which can be particularly important in regions with variable weather patterns.
- Cost-Effectiveness: While the initial manufacturing cost of amorphous silicon panels can be lower, the lower efficiency and shorter lifespan often result in a higher overall cost per watt of electricity generated over the life of the panels. Crystalline silicon panels, despite their higher upfront cost, tend to provide better value in the long run due to their efficiency and durability.
- Aesthetic Considerations: Crystalline silicon panels can come in a variety of styles and colors, making them more aesthetically pleasing for some homeowners and businesses. Amorphous silicon panels typically have a uniform, dark appearance, which may not be as visually appealing to some.
It’s worth noting that amorphous silicon panels have their own advantages, such as flexibility and the ability to perform better in hot climates. As technology advances, there may be further improvements in the efficiency and cost-effectiveness of amorphous silicon panels, making them a more competitive option in certain situations. However, crystalline silicon panels remained the more popular and widely adopted choice for most solar installations due to their proven performance and reliability.
