I have both:
MacBook Pro 13" - now without battery installed as Navigation
MacBook 15" Retina
Both with SSD, 8 and 16Gb RAM
Power consumption of first at least 30% less than other (up to 50%), but still 3-3,5A
I have installed solar panels and wind-charger - but it's not enough for all tasks on sailing boat (radio, AIS, all sensors, light and etc).
This is not a problem on coastal trip, but start be serious on long passages.
