When designing your power system that you will depend on for years to come, it is a good idea to start with your expected energy usage in your home. Typically this is called an Energy Budget. You can refer to my previous post Sizing a Renewable Home Power System to easily determine your Energy Budget.

You can also refer to the post on Basic Concepts of Electricity in order to have a better understanding of the designing process here described.

After you complete an energy budget you will have a better idea of the amount of power production that will be necessary to run your off grid home.

In our next post we shall describe how to select your system power voltage. Stay tuned.
