Questions about this pairing

Which panel is better: Solar-Fabrik Mono S4 Halfcut Trend White 445W or Solar-Fabrik S4-DG620-132TMax?
According to our database: Solar-Fabrik S4-DG620-132TMax has higher module efficiency (22.95% vs 22.27%); Solar-Fabrik Mono S4 Halfcut Trend White 445 W tolerates heat better (temp coeff -0.280%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solar-Fabrik Mono S4 Halfcut Trend White 445W and Solar-Fabrik S4-DG620-132TMax?
Solar-Fabrik Mono S4 Halfcut Trend White 445 W has a module efficiency of 22.27%, while Solar-Fabrik S4-DG620-132TMax is 22.95%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solar-Fabrik Mono S4 Halfcut Trend White 445W use vs Solar-Fabrik S4-DG620-132TMax?
Solar-Fabrik Mono S4 Halfcut Trend White 445 W uses TOPCon cells; Solar-Fabrik S4-DG620-132TMax 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 Solar-Fabrik Mono S4 Halfcut Trend White 445W and Solar-Fabrik S4-DG620-132TMax?
Solar-Fabrik Mono S4 Halfcut Trend White 445 W has a 30 years power warranty; Solar-Fabrik S4-DG620-132TMax has a 25 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 Solar-Fabrik Mono S4 Halfcut Trend White 445W and Solar-Fabrik S4-DG620-132TMax bifacial panels?
Both Solar-Fabrik Mono S4 Halfcut Trend White 445 W and Solar-Fabrik S4-DG620-132TMax 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.
