REC410AA Technical Specifications Deep Dive
Power Output and Efficiency Ratings
The REC410AA delivers 410 watts of power output under Standard Test Conditions (STC), with impressive efficiency ratings of 22.2% for the Pure variant and 21.2% for the Pure-R variant. This high efficiency means more electricity generation per square foot of roof space, making it ideal for homes with limited installation area.
The panel’s PTC (PVUSA Test Conditions) rating ranges from 312W to 391.7W depending on the specific variant, providing a more realistic measure of real-world performance under typical operating conditions.
Physical Dimensions and Weight
Measuring 71.7 inches by 40.0 inches with a depth of just 1.2 inches (30mm), the REC410AA maintains a sleek profile that’s both aesthetically pleasing and practical for installation. The compact 30mm frame height makes handling easier during installation while maintaining structural integrity.
At approximately 45-47.6 pounds, the panel strikes an optimal balance between durability and manageability for installers.
Electrical Characteristics
The REC410AA’s electrical specifications demonstrate its advanced engineering:
- Open Circuit Voltage (Voc): 49.0V – 59.2V (variant dependent)
- Short Circuit Current (Isc): 8.81A – 10.35A
- Maximum Power Voltage (Vmpp): 48.2V – 49.4V
- Maximum Power Current (Impp): 8.3A – 9.98A
- Maximum System Voltage: 1000V DC
Temperature Coefficients and Heat Performance
One of the REC410AA’s standout features is its excellent temperature coefficient performance. With a power temperature coefficient of -0.26% per degree Celsius for the Pure variant and -0.24% for the Pure-R variant, this panel loses minimal efficiency as temperatures rise—significantly better than many conventional panels.
This superior temperature performance translates to higher energy yields in hot climates and during peak summer months, when conventional panels often experience substantial power losses.
REC Alpha Pure Technology Explained
Heterojunction (HJT) Cell Technology
The REC410AA utilizes advanced heterojunction cell technology, which combines crystalline silicon with thin amorphous silicon layers. This hybrid approach delivers several key advantages:
- Higher efficiency: HJT cells achieve superior light absorption and electron collection
- No Light-Induced Degradation (LID): Maintains full power output from day one
- Better low-light performance: Generates more power during cloudy conditions
- Superior temperature coefficients: Less power loss in hot weather
Half-Cell Design Benefits
The REC410AA features 132 half-cells in the Pure variant and 80 half-cells in the Pure-R variant instead of traditional full-size cells, providing multiple performance advantages:
- Reduced power losses: Lower internal resistance improves overall efficiency
- Enhanced durability: Smaller cells experience less mechanical stress
- Better shading tolerance: Partial shading affects smaller portions of the panel
- Improved reliability: Reduced risk of hot spots and cell cracking
Gapless Cell Layout and Power Density
REC’s innovative gapless cell layout maximizes the active area of each panel, capturing more sunlight and boosting power density. This design achieves an impressive power density of 219 watts per square meter for the Pure variant and 217-223 watts per square meter for the Pure-R variant, allowing homeowners to generate more electricity from limited roof space.
Advanced Cell Connection Technology
The REC410AA employs solder-free cell connections, using an increased number of thin wires to improve electrical flow. This advanced connection method:
- Eliminates risk of cell damage from invasive soldering
- Reduces manufacturing-related microcracks
- Provides more uniform current distribution
- Creates a cleaner, more aesthetic appearance
Twin Panel Design and Shading Tolerance
REC’s iconic Twin design splits each panel into two independent sections, reducing internal resistance and improving performance under partial shading conditions. When one section is shaded, the other continues operating at full capacity, maximizing overall energy production.
