Renewable energy systems should be sized so that the total amount of daily charging energy from all sources — PV, wind, hydroelectric, or generator — exceeds a home’s total average daily load. The role of the battery bank is to provide stored energy between charging periods — nothing more. When carefully planned and executed, the batteries in a home power system will run everything in your home — but “everything” will include far less than in a typical mainstream home.

Living well on a small and finite amount of electricity starts with careful adherence to three basic principles: Shift inappropriate loads to other forms of energy, reduce waste through efficiency, and use power in proportion to the amount available.
