Unlocking the Power of Silicon Cells: Key Features and Technology
Silicon cells are the cornerstone of modern solar panels, leveraging advanced technologies to convert sunlight into electricity with high efficiency. The JA Solar JAM54D40-440/LB/1500V utilizes N-type monocrystalline TOPCon (Tunnel Oxide Passivated Contact) cells. This advanced cell technology enhances electron flow, providing higher efficiency and better performance, particularly in low-light conditions. The TOPCon cells also reduce recombination losses, resulting in a higher overall energy yield — An additional standout feature of the JA Solar JAM54D40-440/LB/1500V is its bifacial design allowing the solar panel to absorb light from both the front and the rear sides, increasing overall energy generation and boost energy output by up to 30%, depending on the installation environment.
LONGi’s LR5-54HTB-440M employs monocrystalline PERC (Passivated Emitter and Rear Cell) technology. PERC cells incorporate an additional layer on the rear side of the cell, which reflects unused light back into the cell, thereby increasing energy absorption and efficiency. This technology is particularly effective in improving performance in hotter climates by reducing the temperature-induced degradation.
How Temperature Affects Solar Panel Performance
Temperature impacts the performance of solar panels significantly: Here’s what we know
The temperature coefficient of the short-circuit current (Isc) for JA Solar’s panel is +0.046%/°C and +0.05%/°C for LONGi. The temperature coefficient of the open-circuit voltage (Voc) is -0.26%/°C for JA Solar and -0.23%/°C for LONGi. These coefficients indicate how much the panel’s output decreases with rising temperatures. Both panels exhibit minimal losses, but LONGi’s lower Voc temperature coefficient suggests better performance in hotter Australian climates.
Built to Last: Durability and Longevity
Durability is crucial for long-term solar investments. JA Solar panels are known for their robust build and resistance to harsh environmental conditions, featuring a high load capacity for both wind and snow. Similarly, LONGi panels are designed for longevity, with anodized aluminium frames and high-quality tempered glass to withstand extreme weather.
Performance Metrics: Which Panel Outperforms?
For Business Solar Installations and Home Solar Installations
When comparing efficiency and temperature coefficients, both JA Solar and LONGi panels excel, but their performance varies with climate conditions. The JA Solar JAM54D40-440/LB/1500V operates with a maximum power voltage of 32.47V and a maximum power current of 13.55A. It has a temperature coefficient for Isc of +0.046%/°C and for Voc of -0.26%/°C. These coefficients indicate that while the panel’s current increases slightly with higher temperatures, its voltage decreases moderately, making it resilient in both hot and cold climates making JA the better choice for systems with SolarEdge Optimizers or Enphase Microinverters.
Conversely, the LONGi LR5-54HTB-440M features a maximum power voltage of 33.56V and a maximum power current of 13.12A, with temperature coefficients for Isc at +0.05%/°C and for Voc at -0.23%/°C. These values suggest that LONGi panels have a slight advantage in both increasing current and minimizing voltage loss under high temperatures. This makes the LONGi solar panel particularly suitable for hotter climates critical for overall efficiency. In colder climates, the high current coefficient of LONGi panels can provide a boost in energy production, similar to JA Solar.
