Grid-tied systems? If you are interested in a grid-tied system (connected to the utility grid), the size of the system is only limited by space constraints and your electric utility policies. This is the simplest system with the quickest payback. Specialized grid-tied inverters "invert" DC electricity produced by the solar panels directly into standard AC power to feed your household electricity needs (also called "loads"). If the sun is shining and your have no electricity needs, the inverter syncs with the utility grid and "sells" back the excess electricity to the utility grid ("net metering"). If your house has electricity needs when the sun isn't shining (nighttime), then the utility supplies your electric needs. In this simple scenario, no energy storage is needed. However, Optionally, a grid-tied system can include some energy storage to provide backup power during power failures or for later self-consumption (especially nice in places where the utility prohibits or limits net-metering..

Off-grid systems? If you are interested in a non-grid-tied (that is, not connected to a utility, also called Off-Grid or stand-alone) system, the size of the system must be well matched to the electrical loads. This type of system also requires batteries, and usually a backup generator.
