Questions about this pairing

Which panel is better: Solaria PowerXT 430R-PL or Solaria SPV665-TG12-132BD?
According to our database: Solaria SPV665-TG12-132BD has higher module efficiency (21.44% vs 20.40%); Solaria SPV665-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 PowerXT 430R-PL and Solaria SPV665-TG12-132BD?
Solaria PowerXT 430R-PL has a module efficiency of 20.40%, while Solaria SPV665-TG12-132BD is 21.44%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solaria PowerXT 430R-PL use vs Solaria SPV665-TG12-132BD?
Solaria PowerXT 430R-PL uses Monocrystalline cells; Solaria SPV665-TG12-132BD uses TOPCon. 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 PowerXT 430R-PL and Solaria SPV665-TG12-132BD?
Solaria PowerXT 430R-PL has a 30 years power warranty; Solaria SPV665-TG12-132BD 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 PowerXT 430R-PL and Solaria SPV665-TG12-132BD bifacial panels?
Solaria SPV665-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.
