As has been suggested make a card template for the panel, ensure it is as precise and accurate as possible. Mark the extent of the curved section as accurately as possible. If you have sheet rolls it will be much easier, it might be worth cultivating your friendly local sheetmetal worker (if available) for the curved part. I use card of a similar weight to cereal boxes, infinitely better than corrugated which has “grain”. It might be easier to make three separate parts in card to ensure you have the curved part bang on and hang the flat panels to it with masking tape.
