This system combines power
from grid, solar and generator. It is normally
applicable where grid power in unreliable and a
generator has been installed
as a back-up. Solar panels can be introduced to
take over from the generator so as to reduce
operating expenses and carbon emissions. Because
of the high initial investment associated with
solar panels, the system can be configured in a
such a way that customers can start with a small
number of panels, then add more over a suitable
period. Finally the generator becomes obsolete,
the solar panels or solar panels/grid can
provide power 24/7.
