Technology Behind 225-Watt Panels
- Monocrystalline vs. Polycrystalline Silicon Cells:
- Monocrystalline Cells Feature higher efficiency rates, typically between 15% and 20%, and are made from a single continuous crystal structure. They are known for their long lifespan and superior performance in low-light conditions.
- Polycrystalline Cells: These cells are slightly less efficient, with rates usually from 13-16%. They are composed of multiple silicon crystals melted together. However, they are generally more affordable and have a simpler manufacturing process, making them a cost-effective option.
- PERC (Passivated Emitter and Rear Cell) Technology:
- PERC technology enhances the efficiency of solar panels by adding a dielectric passivation layer on the rear side of the cells. This layer reflects more light into the cell, allowing for more excellent absorption and reducing electron recombination. PERC cells can increase the energy yield of solar panels, particularly in conditions of high temperature and low light.
- Half-Cut Cell Design:
- Half-cut solar cells improve shading tolerance and boost the panel’s overall efficiency. Cutting standard silicon solar cells in half reduces the resistance within the cells, leading to higher output and more reliable performance. This design also helps minimize the power loss caused by shading and enhances the panel’s durability.
