Simple, don't drive a stake in a shade area.. the sun obstruction will be obvious. The stakes with the shortest shade will have the most direct sun angle... long shade means you are in a low sun angle, not good for absorbing UV to make electric..
Think, sun dial... when the sun is at high noon... directly overhead... how long is the sundial shadow?
