See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Solar-Fabrik S4-DG455-96TMax (White) and Solar-Fabrik Mono S4 Halfcut Trend White 450W?

Solar-Fabrik S4-DG455-96TMax (White) has a module efficiency of 22.80%, while Solar-Fabrik Mono S4 Halfcut Trend White 450W is 22.53%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Solar-Fabrik S4-DG455-96TMax (White) use vs Solar-Fabrik Mono S4 Halfcut Trend White 450W?

Solar-Fabrik S4-DG455-96TMax (White) uses TOPCon cells; Solar-Fabrik Mono S4 Halfcut Trend White 450W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Solar-Fabrik S4-DG455-96TMax (White) and Solar-Fabrik Mono S4 Halfcut Trend White 450W?

Solar-Fabrik S4-DG455-96TMax (White) has a 30 years power warranty; Solar-Fabrik Mono S4 Halfcut Trend White 450W 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.

Q: Are Solar-Fabrik S4-DG455-96TMax (White) and Solar-Fabrik Mono S4 Halfcut Trend White 450W bifacial panels?

Both Solar-Fabrik S4-DG455-96TMax (White) and Solar-Fabrik Mono S4 Halfcut Trend White 450W 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.
