JAM54S31-405/MR/1500V 405W Solar Panel
The JA Solar JAM54S31-405/MR/1500V module utilizes monocrystalline PERC cells in a half-cell configuration, offering 405W of power output for both residential and commercial solar installations. Built with an 11 busbar design, this panel delivers reliable performance across various light conditions while the half-cell layout helps reduce internal power losses.
Featuring JA Solar's "DEEP BLUE 3.0" technology, the JAM54S31 series combines practical functionality with visual appeal. The all-black construction provides a clean, uniform appearance that integrates well with most architectural styles. With a module efficiency of 20.7% and comprehensive warranty coverage, this panel represents a practical option for those seeking a balance of performance and value in their solar investment.
JAM54S31-405/MR/1500V Features
- Half-Cell Configuration: Uses 11BB PERC cells in a half-cell layout that reduces internal resistance, improves shade tolerance, and minimizes hot spot risk.
- 20.7% Module Efficiency: Helps maximize power generation within the available installation space.
- Mechanical Load Capacity: Tested to withstand up to 5400 Pa front load and 2400 Pa rear load.
- Low Annual Degradation: With just 0.55% annual degradation after the first year, the panel maintains higher output over its lifetime compared to standard modules.
- Uniform Black Appearance: Module features black cells, black backsheet, and black frame, providing a consistent appearance that complements most building designs.
JAM54S31-405/MR/1500V Warranty
JA Solar provides a 12-year product warranty covering materials and workmanship defects, plus a 25-year linear power output warranty. The power warranty guarantees that module output will be no less than 83.1% of nominal power after 25 years, with only 2.5% degradation in the first year and 0.6% annual degradation thereafter.
JAM54S31-405/MR/1500V 405W Solar Panel Review
The JA Solar's JAM54S31-405W half-cell design provides practical benefits in real-world applications, particularly in locations that experience partial shading or where maximizing energy production per square foot is important. The build quality, comprehensive certifications (IEC 61215, IEC 61730, ISO 9001, ISO 14001, and ISO 45001), and thorough warranty coverage make this a suitable option for both home and business installations. The 0.55% annual degradation rate also helps maintain higher energy production over the system's lifetime compared to many standard modules, potentially improving the economics of solar projects.
