If a manufacturer has an OG-300 Puerto Rico Supplement for their solar water heater, does that mean that they also have ENERGY STAR certification?

Not necessarily.  ENERGY STAR certification is not required to obtain the OG-300 Puerto Rico Supplement.  But if a manufacturer has ENERGY STAR certification for the system through ICC-SRCC, it will be noted on the supplement.
