Questions about this pairing

Which panel is better: Solaria SPV670-TG12-132BD or Solaria PowerXT 430R-PL?
According to our database: Solaria SPV670-TG12-132BD has higher module efficiency (21.59% vs 20.40%); Solaria SPV670-TG12-132BD tolerates heat better (temp coeff -0.300%/°C vs -0.390%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solaria SPV670-TG12-132BD and Solaria PowerXT 430R-PL?
Solaria SPV670-TG12-132BD has a module efficiency of 21.59%, while Solaria PowerXT 430R-PL is 20.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solaria SPV670-TG12-132BD use vs Solaria PowerXT 430R-PL?
Solaria SPV670-TG12-132BD uses TOPCon cells; Solaria PowerXT 430R-PL uses Monocrystalline. 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 Solaria SPV670-TG12-132BD and Solaria PowerXT 430R-PL?
Solaria SPV670-TG12-132BD has a 30 years power warranty; Solaria PowerXT 430R-PL has a 30 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 Solaria SPV670-TG12-132BD and Solaria PowerXT 430R-PL bifacial panels?
Solaria SPV670-TG12-132BD is bifacial (captures light from both faces); Solaria PowerXT 430R-PL is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
