Parameter	Approx. Value
Peak Power (STC)	590 Wp
Cell Type	N-type TOPCon (often half-cut or large cell format)
Number of cells	144 cells (often in a 624 arrangement or similar)
Module Efficiency	22.5-23.0% or slightly higher for front side under STC conditions
Open-Circuit Voltage (Voc)	51-52 V
Voltage at Maximum Power (Vmp)	43-44 V
Current at Maximum Power (Imp)	13.5-14.0 A
Weight	30-32 kg
Dimensions	around 2278 1134 30 mm (varies slightly)
Temperature Coefficients	Pmax: approx -0.25 to -0.29 %/C; Voc more negative; Isc small positive slope.
System Voltage Capability	1500 V DC is common in modern large modules.
Bifacial Gain (rear side)	Varies by installation/tape/gain: maybe 5-25%, depending on albedo etc.

Higher energy yield per module due to bifacial gain (if installation allows rear light).
Better performance under non-ideal conditions (low light, higher temperature) because of TOPCon tech.
Fewer modules needed for the same power target (saves on structure, mounting, wiring, space).
Lower degradation over time compared to older PERC modules.

What is the rear-side albedo (reflectivity) in your setup? Plain ground gives less gain; reflective surfaces (white concrete, sand, etc.) give more.
Mounting height and tilt: rear side needs space/light.
Mechanical load ratings: snow, wind, hail. These large modules are heavy and large, so structure must be adequate.
Temperature coefficients and NOCT (Nominal Operating Cell Temperature) values: higher temperature means power drop.
Warranty: product warranty (years), output warranty (how much power remains after e.g. 25-30 years).
Safety and quality certifications: e.g. IEC 61215 / IEC 61730, BIS / MNRE approvals (for India), etc.
