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: Philadelphia Solar PS-MNB156(HCBF)-630W or Philadelphia Solar PS-MNB156(HCBF)-635W?
According to our database: Philadelphia Solar PS-MNB156(HCBF)-635 W has higher module efficiency (22.75% vs 22.57%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Philadelphia Solar PS-MNB156(HCBF)-630W and Philadelphia Solar PS-MNB156(HCBF)-635W?
Philadelphia Solar PS-MNB156(HCBF)-630 W has a module efficiency of 22.57%, while Philadelphia Solar PS-MNB156(HCBF)-635 W is 22.75%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Philadelphia Solar PS-MNB156(HCBF)-630W use vs Philadelphia Solar PS-MNB156(HCBF)-635W?
Philadelphia Solar PS-MNB156(HCBF)-630 W uses N-type cells; Philadelphia Solar PS-MNB156(HCBF)-635 W 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 Philadelphia Solar PS-MNB156(HCBF)-630W and Philadelphia Solar PS-MNB156(HCBF)-635W?
Philadelphia Solar PS-MNB156(HCBF)-630 W has a 30 years power warranty; Philadelphia Solar PS-MNB156(HCBF)-635 W 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 Philadelphia Solar PS-MNB156(HCBF)-630W and Philadelphia Solar PS-MNB156(HCBF)-635W bifacial panels?
Both Philadelphia Solar PS-MNB156(HCBF)-630 W and Philadelphia Solar PS-MNB156(HCBF)-635 W 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.
