Questions about this pairing

Which panel is better: Tata Power Solar TP642LG10B or Tata Power Solar TP530HG10TB?
According to our database: Tata Power Solar TP642LG10B has higher module efficiency (23.05% vs 20.52%); Tata Power Solar TP530HG10TB tolerates heat better (temp coeff -0.360%/°C vs -0.370%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Tata Power Solar TP642LG10B and Tata Power Solar TP530HG10TB?
Tata Power Solar TP642LG10B has a module efficiency of 23.05%, while Tata Power Solar TP530HG10TB is 20.52%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Tata Power Solar TP642LG10B use vs Tata Power Solar TP530HG10TB?
Tata Power Solar TP642LG10B uses PERC cells; Tata Power Solar TP530HG10TB uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Tata Power Solar TP642LG10B and Tata Power Solar TP530HG10TB?
Tata Power Solar TP642LG10B has a 30 years power warranty; Tata Power Solar TP530HG10TB has a 25 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are Tata Power Solar TP642LG10B and Tata Power Solar TP530HG10TB bifacial panels?
Both Tata Power Solar TP642LG10B and Tata Power Solar TP530HG10TB are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
