connected Solar Power Systems
solar power systems are the very latest technology,
and can be likened to having your own solar
power station located on your house roof, that
silently generates green electricity for your
own use. As the grid power is always available,
it is therefore not essential that the solar
power system be sized to exactly match what
your daily power usage is. If you generate more
power than what you use, the balance excess
power is fed back into the grid. When your system
doesn't produce enough power, then you get power
from the grid (e.g. night time). Grid interactive
solar systems eliminate the need for a battery.
In effect, the grid serves as your battery.
This means that maintenance costs for your system
will be less. It should be noted that without
battery storage a grid connected system will
shut down when there is no power on the grid.
panels collect the sun’s energy as direct
current (DC) electricity. An inverter converts
the DC power into conventional 240 volt 50Hz
AC power, as used in the home. This supply is
then connected into your home’s normal
power supply at the switchboard. Any difference
between the power required in your home and
the power generated by the system is provided
through the main grid. If the system generates
more solar power than your house needs, the
excess is exported back to the main grid.
in all countries, to install a grid connected
system, the consumer needs to get the permission
from the local Utility Company. The local utility
company has rules and procedures that must be
followed to connect any Solar Power System to
the grid safely and legally.
solar generating systems don’t require
choosing between solar electricity and the utility.
Solar generating systems work in parallel to
the grid, providing the best possible combination
of reliability, pricing and sustainability benefits.
The inverter automatically synchronises with
the network; no additional controls are required.
The major components of a grid-connected solar
generating system are as follows:
Rooftop Solar Array converts
sunlight into electricity via the photovoltaic
converts the direct current electricity
from the solar modules to utility-grade
alternating current that is perfectly synchronized
with the utility grid.
Energy Meter (reversible) measures
the net energy consumed by the customer.
The meter spins forward when the customer
draws energy from the utility grid and the
meter spins backward when excess PV energy
is fed to the grid.
Distribution occurs via the building’s
existing electric panel with no additional
Grid supplies electricity when
the building load exceeds the solar generating
system’s output and absorbs exported
electricity when the system output exceeds
Electrical Loads are fed from both
the solar generating system and the utility
grid, seamlessly and transparently.

Systems to suit your requirement and budget.
