How an Off Grid Solar
System Works
OFF GRID refers to a power system
that generates electricity such as a solar array.
The energy produced is stored in batteries and the
energy system isn't connected to the utility power
grid.
ON GRID refers to a energy power system that's
connected to the utility power grid. In the case of
a solar energy system, excess power from the solar
array, not used by the home/business is fed into the
utility grid and the utility meter records the power
excess as a credit. This excess is then used when
solar power is not available. Batteries aren't
needed in a on grid system.
