Additionally, polycrystalline panels have a blueish hue, which is a result of the manufacturing process. This color does not impact their efficiency or performance.
2. Efficiency and Performance
Polycrystalline solar panels have a slightly lower efficiency compared to monocrystalline panels. This is because the multiple crystals within the cells create some inefficiencies in the flow of electrons. Nevertheless, advancements in technology have significantly improved the efficiency of polycrystalline panels over the years.
Despite their slightly lower efficiency, polycrystalline panels still offer excellent performance in generating electricity from sunlight. They are particularly effective in areas with high levels of sunlight and can withstand various weather conditions.
3. Pros and Cons
Pros:
- Affordable option for solar installations
- Good performance in high sunlight areas
- Durable and weather-resistant
- Widely available in the market
Cons:
- Slightly lower efficiency compared to monocrystalline panels
- Less space-efficient
- Blueish hue may not be aesthetically appealing to some
