Suppose shading this could make a big (300 w) difference?

I would think voltagw is dropping or the compressor is failing, how
old is it

Clearly all of you know nothing about air conditioning. Go ask any
hvac tech about the refrigerant pressures and compressor current draw
as the outside air temp goes from 70 to 100.

Shading the house to reduce the heating effect on the house can make a
difference. Shading the unit will make no appreciable difference. If
you don't believe me go get one of those killawatt meters and try it
yourself.
