3. Solar
and
Wind
Energy
is
becoming
an
appealing
energy
source
worldwide.
Many
people
find
a,rac/ve
the
idea
of
powering
their
homes
or
small
business
using
a
renewable
energy
system.
4. This
makes
sense
in
terms
of
reducing
energy
expenses
by
becoming
independent
from
power
providers,
but
as
well
as
demonstra/ng
a
Eco-‐Friendly
way
of
living.
7. Overview
Recent
technological
advancements,
made
possible
the
combina/on
of
wind
and
solar
energy
with
the
development
of
hybrid
systems.
With
these
systems,
implemen/ng
Solar/Wind
energy
into
most
homes,
has
become
rela/ve
easy.

9. Main
Benefits
The
combina6on
of
renewable
resources
has
many
benefits.
The
main
are:
➡
Reduces
the
energy
expenses
of
the
house.
➡
Ensures
an
increased
energy
produc6on
and
a
consistent
power
supply.
➡
Solar/Wind
Hybrid
System
requires
less
space
than
previous
systems.
➡
Eco-‐Friendly.
10. How
it
works
Solar/Wind
Hybrid
systems
are
developed
with
the
natural
con6nuous
change
of
the
weather
condi6ons
in
mind.
Usually
sun
and
wind
are
not
high
at
the
same
6me.
Combining
Solar
Panels
with
Wind
Turbines,
we
can
maximize
the
energy
produc6on,
by
gathering
and
conver6ng
power
from
both
these
2
sources.
The
use
of
a
baLery
system
aids
to
provide
a
storage
unit
for
the
produced
energy,
that
will
be
used
under
periods
of
energy
shortage.
This
way,
we
can
ensure
a
non-‐intermiLent
power
supply
during
all
the
year,
independent
of
the
weather
condi6ons.
11. Equipment
A
complete
stand-‐alone
power
system
requires
the
purchase
of
the
following
equipment:
-‐
Photovoltaic
Array
(Solar
Panels)
-‐
Wind
Turbines
-‐
BaLeries
-‐
Charge
Controller
-‐
Power
Condi6oning
Equipment
-‐
Inverter
-‐
Safety
Equipment
-‐
Metering/Monitoring
Op6onally,
a
stand-‐alone
system
can
include
either
an
engine-‐generator
or
micro-‐hydropower
resources,
to
generate
energy
when
solar
and
wind
energy
is
not
enough.
12. PV
Array
A
Photovoltaic
array
is
an
arrangement
of
mul6ple
photovoltaic
modules
(solar
panels),
designed
in
such
a
way
to
collect
the
solar
radia6on
and
convert
it
into
electricity.
!
The
number
of
the
panels
determines
the
total
electric
power
a
system
is
capable
to
generate.
A
small
PV
system
is
capable
to
provide
enough
power
for
the
average
needs
of
a
house.
Solar
Panels
can
be
mounted
on
the
ground
or
on
the
roofs.
13. Wind
Turbine
A
wind
turbine,
is
a
device
that
converts
the
kine6c
energy
from
the
wind
into
electric
power.
!
Wind
Turbines
have
a
long
technological
history,
that
leaded
to
today’s
wide
range
of
wind
turbines
types.
In
stand-‐alone
energy
systems
for
homes,
small
to
medium
size
turbines
are
used
as
a
complimentary
generator
to
contribute
to
the
domes6c
power
needs.
14. BaGeries
BaLeries
store
the
generated
electricity
for
use
when
the
system
is
not
able
to
produce
(e.g.
cloudy
days,
nights
with
no
wind
etc).
They
usually
have
a
life-‐cycle
of
5-‐10
years
and
can
be
replaced
when
they
lose
their
recharging
ability.
The
number
of
baLeries
is
depending
on
the
actual
needs
and
the
climate
condi6on
at
the
loca6on
of
the
installa6on.
BaLeries
should
not
be
located
in
living
areas
or
near
other
electronics.
It’s
good
to
be
placed
in
a
separate
room,
with
easy
access
for
maintenance
and
replacement.
15. Hybrid
Charge
Controller
This
device
is
used
to
control
the
flow
of
the
electric
power
from
the
various
sources
to
the
baLeries
and
the
home
equipment.
!
Controller
is
detec6ng
and
op6mizing
the
electricity
flow
among
the
electric
devices
and
the
baLeries,
based
on
the
charging
state
of
the
baLeries,
the
current
produced
energy
and
the
power
requirements
of
the
other
devices.
Modern
Controllers
are
able
to
re-‐act
on
the
changing
condi6ons
and
for
example
automate
the
start
of
an
engine-‐generator
in
case
of
energy
shortage,
or
control
the
charging
cycle
of
the
baLeries,
something
that
can
extend
the
baLery’s
life6me.
16. Power
CondiIoning
Equipment
!
Most
electrical
devices
and
equipment
run
on
AC
(alterna6ng
current)
Electricity.
At
the
other
hand,
renewable
energy
technology
produces
and
delivers
DC
(direct
current)
Electricity.
In
order
to
run
AC
devices,
the
DC
electricity
must
be
converted
to
AC.
An
inverter
is
such
a
device.
Sensi6ve
electronic
equipment
like
computers,
televisions
etc,
require
a
consistent
voltage
and
a
smooth
sine
wave
profile
of
electric
power.
Inverters
and
other
power
condi6oning
equipment
are
used
to
equalize
the
requirements
between
the
devices
connected
to
the
home
circuit
and
the
power
provided
by
the
system.
17. Safety
Equipment
It
is
always
important
to
enhance
the
safety
of
an
electric
system,
in
order
to
protect
the
system
itself
against
damages,
but
also
people
from
harming.
The
main
dangers
are
during
storms
with
lightening
events,
power
surges,
short-‐circuits
events,
devices
malfunc6on
etc.
Main
protec6on
against
such
hazards
includes:
-‐
Safety
Disconnects:
Automa6c/Manual
safety
disconnects
to
protect
the
system
or
human,
during
accidents
or
maintenance.
-‐
Grounding:
Power
generators
and
electric
devices
need
to
be
grounded.
-‐
Surge
Protec6on.
18. Metering
&
Monitoring
Devices
to
meter
and
monitor
the
power
consumed,
the
charging
level
of
baLeries,
the
baLeries
voltage
etc.
19. Planning
The
exact
type
of
equipment
and
the
number
of
units
you
are
going
to
need
to
power
your
home
of
office,
is
depending
on
what
you
want
your
system
to
do.
The
simplest
system
is
to
directly
connect
the
power
generated
by
the
system
to
your
home
equipment
for
immediate
use.
But
if
you
want
to
also
store
the
excess
of
the
generated
power,
then
you
are
going
to
need
baLeries,
charging
controllers
etc.
Please
do
not
hesitate
to
contact
us
with
the
requirements
of
your
installa6on
and
we
will
plan
for
you
the
right
solu6on.
