Questions about this pairing

Which panel is better: Solar-Fabrik Mono S4 Halfcut BC Full Black 475W or Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W?
According to our database: Solar-Fabrik Mono S4 Halfcut BC Full Black 475 W has higher module efficiency (23.30% vs 22.30%); Solar-Fabrik Mono S4 Halfcut BC Full Black 475 W tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°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 BC Full Black 475W and Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W?
Solar-Fabrik Mono S4 Halfcut BC Full Black 475 W has a module efficiency of 23.30%, while Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W is 22.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solar-Fabrik Mono S4 Halfcut BC Full Black 475W use vs Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W?
Solar-Fabrik Mono S4 Halfcut BC Full Black 475 W uses Back Contact cells; Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W 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 BC Full Black 475W and Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W?
Solar-Fabrik Mono S4 Halfcut BC Full Black 475 W has a 30 years power warranty; Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 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 Solar-Fabrik Mono S4 Halfcut BC Full Black 475W and Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W bifacial panels?
Both Solar-Fabrik Mono S4 Halfcut BC Full Black 475 W and Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 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.
