The sun is important for a lot of things. Your vegetable garden will not thrive without enough direct sunlight. The use of solar panels is only worth the effort when you have enough direct sunlight at the right angle. Light in your house during the day is desirable.
Knowing the position of the sun on your location is key to whether you will have enough sunlight on your Homestead.
At the other hand shade can also be important in places where it gets very hot in summer. Having to much hot burning sunshine in your vegetable garden will not be good for your lettuce and radishes. These crops, that need a lot of moisture will not grow in the burning hot sun.
Your house might heat up to much, instead you would want some coolness in the house in hot summers.
