What it means on a roof
Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: Premier Energies PE-132-605-THGB-G12R or Premier Energies PE-132-620-THGB-G12R?
According to our database: Premier Energies PE-132-620-THGB-G12R has higher module efficiency (22.95% vs 22.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Premier Energies PE-132-605-THGB-G12R and Premier Energies PE-132-620-THGB-G12R?
Premier Energies PE-132-605-THGB-G12R has a module efficiency of 22.40%, while Premier Energies PE-132-620-THGB-G12R is 22.95%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Premier Energies PE-132-605-THGB-G12R use vs Premier Energies PE-132-620-THGB-G12R?
Premier Energies PE-132-605-THGB-G12R uses N-type cells; Premier Energies PE-132-620-THGB-G12R uses N-type. 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 Premier Energies PE-132-605-THGB-G12R and Premier Energies PE-132-620-THGB-G12R?
Premier Energies PE-132-605-THGB-G12R has a 30 years power warranty; Premier Energies PE-132-620-THGB-G12R 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 Premier Energies PE-132-605-THGB-G12R and Premier Energies PE-132-620-THGB-G12R bifacial panels?
Both Premier Energies PE-132-605-THGB-G12R and Premier Energies PE-132-620-THGB-G12R 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.
