The usual approach is to take a conventional house design, and then design a solar supply to meet its needs. This results in a crazy large system due to our appalling wasteful house designs (which in turn are due to historically cheap electricity). A better approach is to decide how much you can spend on solar, then design a house which will function within that limitation. To succeeded you will need to change house designs, select different type and size of appliances, and most importantly, make some personal sacrifices. If you can live within these limits, then yes, you will enjoy having Solar. If not, you would be better to continue with your existing expensive lifestyle.
