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: Mission Solar MSH10-590HN4G or Mission Solar MSH10-595HN4G?
According to our database: Mission Solar MSH10-595HN4G has higher module efficiency (23.00% vs 22.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Mission Solar MSH10-590HN4G and Mission Solar MSH10-595HN4G?
Mission Solar MSH10-590HN4G has a module efficiency of 22.80%, while Mission Solar MSH10-595HN4G is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Mission Solar MSH10-590HN4G use vs Mission Solar MSH10-595HN4G?
Mission Solar MSH10-590HN4G uses N-type cells; Mission Solar MSH10-595HN4G 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 Mission Solar MSH10-590HN4G and Mission Solar MSH10-595HN4G?
Mission Solar MSH10-590HN4G has a 30 years power warranty; Mission Solar MSH10-595HN4G 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 Mission Solar MSH10-590HN4G and Mission Solar MSH10-595HN4G bifacial panels?
Both Mission Solar MSH10-590HN4G and Mission Solar MSH10-595HN4G 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.
