What are PERC Solar Panels?

2. Mono PERC solar panels are an advanced type of photovoltaic panel designed to enhance the efficiency of converting sunlight into electricity. The key innovation in PERC technology lies in the additional layers and processes used in their construction, which improve their overall performance. The primary difference between PERC panels and traditional solar panels is the inclusion of an extra layer on the back of the solar cells. This layer, known as the passivation layer, serves two main functions: 1. Reflecting Unabsorbed Light: In conventional solar cells, some light passes through the cell without being absorbed. The passivation layer in PERC panels reflects this unabsorbed light back into the cell, giving it another chance to be converted into electricity. Reducing Electron Recombination: Electron recombination is a process where electrons and holes (positive charge carriers) recombine before contributing to the electric current, leading to energy loss. The passivation layer in PERC cells reduces this recombination, thereby increasing the cell's efficiency. 2.

4. 1. Material Composition Mono PERC: Made from a single crystal structure, typically silicon. The monocrystalline silicon cells are produced using the Czochralski process. Poly PERC: Made from multiple silicon crystals melted together. These cells are produced using a casting method. 2. Efficiency Mono PERC: Generally more efficient than poly PERC panels. This is due to the higher purity and better crystal structure of monocrystalline silicon, which allows for more efficient electron flow. Poly PERC: Typically less efficient compared to mono PERC panels. The presence of multiple crystals creates more grain boundaries, which can impede electron flow and reduce efficiency. 3. Temperature Coefficient Mono PERC: Generally have a better (lower) temperature coefficient, meaning they lose less efficiency in high temperatures compared to polycrystalline panels. Poly PERC: Usually have a higher temperature coefficient, leading to more efficiency loss in high temperatures. 4. Cost Mono PERC: Typically more expensive due to the higher manufacturing costs associated with producing monocrystalline silicon. Poly PERC: Generally less expensive due to the simpler manufacturing process of polycrystalline silicon.

5. PERC (Passivated Emitter and Rear Cell) solar panels are a type of photovoltaic technology that has gained popularity due to their improved efficiency and performance. When comparing Mono PERC solar panel with other advanced panel technologies, it's important to consider several factors including efficiency, cost, durability, and application suitability. Here's a detailed comparison: 1. Bifacial Solar Panels Key Features: These panels can capture light from both the front and the back, increasing overall energy generation. They are typically installed with a reflective surface underneath to maximize rear-side energy capture. 2. Heterojunction Technology (HJT) Panels Key Features: Combines crystalline silicon with amorphous silicon layers, resulting in very high efficiency and excellent temperature performance. 3. Thin-Film Solar Panels (e.g., CdTe, CIGS) Key Features: Made from lightweight materials and flexible substrates, allowing for more versatile applications.
