Stand-alone
PV Power System (off-grid)
System includes:
1. PV Array: A
number of PV panels connected in
series and/or in parallel giving
a DC output out of the incident
irradiance. Orientation and tilt
of these panels are important
design parameters, as well as
shading from surrounding
obstructions.
2. PV
controller: control battery bank
charge and discharge reasonable
and safety.
3. Inverter: A
power converter that “inverts”
the DC power from the panels
into AC power. The
characteristics of the output
signal should match the voltage,
frequency and power quality
limits in the supply network.
4. Battery bank:
can be a single battery or
multiple batteries connected
together to create essentially
one large battery of the
required voltage and amp-hour
capacity. In some ways the
battery configuration and
capacity are the most important
electrical power decision to
make, and a wise choice can help
guarantee a steady supply of
electrical power as well as a
system that is simple to operate
and maintain.
5. Loads: Stands
for the network connected
appliances in the building that
are fed from the inverter, or,
alternatively, from the grid
 .

Grid
Connected PV system
design has the following
components:
1. PV Array or
Generator: A number of
PV panels connected in
series and/or in
parallel giving a DC
output out of the
incident irradiance.
Orientation and tilt of
these panels are
important design
parameters, as well as
shading from surrounding
obstructions.
2.
Inverter: A power
converter that “inverts”
the DC power from the
panels into AC power.
The characteristics of
the output signal should
match the voltage,
frequency and power
quality limits in the
supply network.
3.
Loads: Stands for the
network connected
appliances in the
building that are fed
from the inverter, or,
alternatively, from the
grid.
4.
Meters: They account for
the energy being drawn
from or fed into then
local supply network.
5. Local
Supply Network: A single
or three-phase network
managed by a Public
Electricity Supplier.
The supply network acts
both as a sink for
energy surplus in the
building or as a backup
for low local generation
periods.
