The 21-year-old produced an error-free Sunday drive on his home rally to steer his Škoda Fabia RS Rally2 to a 42.3sec buffer over Veiby, with the Norwegian having to settle for the runner-up position a second year running in his Volkswagen Polo GTi R5.
Rounding out the top three in an identical Fabia to Solberg was fellow 21-year-old Sami Pajari, with the 2021 FIA Junior WRC champion recording his maiden WRC2 podium.
Solberg started the final day of action in Sweden’s snowy north with a 51.6sec buffer over Veiby. With such a lead in hand, he could afford for a conservative approach to the remaining 63.04 competitive kilometres.
That didn't stop him from going all-out in the Wolf Power Stage, however, and he secured maximum bonus points after outpacing Emil Lindholm by 0.5sec in the finale.
"It's fantastic - what a great feeling!" Solberg exclaimed. "It's been a long time since I won, and finally everything worked correct and I am really happy. Elliott (Edmondson, co-driver) did an amazing job and for sure it's been an amazing weekend - no mistakes and really consistent."
