Evacuated tubes are aligned in parallel; the angle of mounting depends upon the latitude of your location. In a North South orientation the tubes can passively track heat from the sun all day. In an East West orientation they can track the sun all year round.
The efficiency of a evacuated water heater is dependent upon a number of factors, one important one being the level of evacuated radiation in your region.
