Here are typical parameters you might expect, based on similar modules and the hints above:

Spec	Approx. / Likely Value
Peak Power (STC)	690 Wp
Cell Type	N-type TOPCon (or very high performance mono PERC / bifacial)
Efficiency (front or overall)	Probably 25-28% (depending on whether bifacial or not)
Module Size (dimensions)	Large: something like 2.2-2.5 m length 1.13-1.30 m width, thickness maybe 30-35 mm including frame/glass. (Based on other Waaree modules)
Weight	Likely 30-35 kg (may vary)
Operating Temperature Range	Probably 40 C to +85 C or similar, as many current Waaree modules have that across their Elite / BiN / TOPCon ranges.
Temperature Coefficient of Power	Perhaps around 0.28 to 0.35 %/C (loss of power as temperature rises)
System Voltage	Likely up to 1500 V DC (common for high wattage modules)
Warranty	Product warranty maybe 12 years or more; power output warranty 25 years (with guaranteed remaining power like 80-85 %) based on Waarees other offerings.

Higher power per module means fewer modules needed for the same capacity savings in mounting, wiring, installation labor.
Using N-type / TOPCon can reduce degradation (LID, LeTID) and provide better performance at higher temps or low light.
If module is bifacial, you might get extra energy from reflected light on the rear side.
Waaree is an established manufacturer in India; often modules from Tier-1 are more reliable.

The larger size and weight require more robust mounting structure, careful handling, transportation logistics.
Bifacial gain depends heavily on installation (albedo, ground reflectivity, tilt, height above ground). If rear side is blocked or poorly supported, gain will be low.
Check mechanical load ratings: wind, snow, hail if applicable to your location.
Check actual datasheet for temperature coefficient, NOCT (Nominal Operating Cell Temp) real world output usually lower than STC spec.
Confirm warranty details: both product (defects, degradation) and performance (how much power remains after years).
Certifications (IEC / BIS / MNRE etc.) important for safety, insurance, subsidy eligibility.
