Where should i intent to put the aircon compressor?
Is there any difference if i put it under direct sunlight compare to shade area? Will it consume more power and less cold if put on the wall which is facing WEST (sunset direction) ?

Saw all the supermarket compressor are put on top ot their roof.

there's no difference... the only important factor to take accouint is ventilation. as long as the compressor has good ventilation and protection from rain n dust, it should work well.

supermarkets might have chilled water as their coolant and water as their fluid to release heat. so they have to be on top no matter what.

the most important is ur outdoor compressor is not far from ur indoor unit

some are made to be far away from each other. the big ones use chill water as transmition

I put all my AC compressor on my rooftop there, first of all, your house looks nicer, let's face it, those compressors are fugly. Second, those metal thingy that support your compressor, it gets rusty after some time and will ruin your wall paint. Take a look at your neighbours and you'll know what I mean. 3rdly, servicing those compressors would be easy, I installed a tap on my roof for them to wash as well.

The downside would be the cost, I did all the concealed copper piping when I did my renovation, it is not recommended if you're staying in the house, just think of all the hacking and dust.
And copper pipe isn't cheap either, imagine running from your living room to your rooftop.

within 10 feet from internal blower unit.
on top of the roof is good, rain can help you to clean it, but cost more $$

I would advice putting it out of the sun. The more heat the condenser coil can expel away, the more efficient is the aircon.

The piping length depends on model. All of them has a limitation of max length. There are some models that can go 135m. Most single split 1HP class aircon goes about 25m as the max piping length.
