Wanderers have been criticised on many occasions this term for following positive first-half performances with below-par displays after the break.
But that was not the case in Saturday's derby clash as Wolves stirred from a slow start, nicked a 34th-minute winner courtesy of Marlon King's own goal, and built up a head of steam after the interval.
It was enough to end the club's long wait for a home win at the seventh attempt.
"We talked at half-time that we should start with a high tempo because I think we finished the first half gradually better, there were not as many technical mistakes," boss Solbakken said.
"We struggled in the first half, especially with the left-hand side defensively, Birmingham played very easily through us there and I said to Sako after the game that he started half-an-hour after the 5.20pm kick-off.
"In the second half he destroyed them, really. And Bjorn (Sigurdarson) came more into the pitch and they struggled more to keep up with our pace."
