(OP)
the vapor pressure of ammonia and water increases with temperature. if this solution is in a metal tank in the sunlight, and the solution temperature rises, will the actual tank pressure increase with the vapor pressure?

If the tank has no vent then the tank pressure will be equal to the vapor pressure of the solution inside for the given temperature.

Aqueous ammonia tanks with solutions >19% do indeed exist and this is a well known technology.
As I recall, the typical tank is a coded pressure vessel designed to ~30 psig.
Lower concentrations can be handled by a "flat-bottomed" API-650 type tank with a conservation vent.
