Poly solar panels, short for polycrystalline silicon solar panels, are a type of photovoltaic panel used to convert sunlight into electricity. They are made from silicon crystals that are melted together, resulting in a less uniform appearance compared to monocrystalline panels but generally lower production costs. Poly solar panels are known for their efficiency and affordability, making them a popular choice for residential and the price of poly-crystalline solar panels in Pakistan can vary widely based on several factors including brand, wattage, and quality. To get the most accurate and current pricing, I recommend checking with local solar panel suppliers or visiting their websites. Prices can fluctuate due to market conditions and currency exchange rates, so it’s best to get the latest information from a reliable source.
The main differences between monocrystalline (mono) and polycrystalline (poly) solar panels lie in their efficiency, cost, and appearance.
1. Efficiency: Monocrystalline solar panels are generally more efficient than polycrystalline panels. This means they can generate more electricity per square foot of panel installed.
2. Cost: Historically, monocrystalline panels have been more expensive to produce than polycrystalline panels due to their manufacturing process. However, this cost difference has narrowed over time as technology advances and production scales up.
3. **Appearance**: Monocrystalline solar cells are typically black in colour, while polycrystalline cells are bluish in olor. This aesthetic difference may be a consideration depending on the installation location and preferences.
4. Performance in High Temperatures: Monocrystalline panels tend to perform better than polycrystalline panels in high temperatures. This is because monocrystalline panels have higher efficiency ratings at higher temperatures, which can be important in hot climates.
Choosing between mono and poly panels often comes down to specific project requirements, budget constraints, and space availability.
