2. So here is a breakdown of the sizing and amperage draw so that you can get an overall estimate of power draw. All the air
handlers are 220V.

Gentlemen,
Joseph
Marino,
DC
Power
Systems
Founder,
and
I
are
happy
to
help
in
any
way
we
can,
as
you
get
closer
to
realizing
your
vision
with
the
Green
Houses.
Thank
you
for
getting
me
the
raw
data
that
was
used
to
get
an
idea
of
the
projects’
solar
needs.
For
the
purpose
of
having
a
starting
point
on
the
solar
options
for
the
Green
Houses,
we
are
using
data
from
Los
Angeles
(the
location
of
the
first
installation).
The
data
that
is
represented
in
this
documents
is
to
give
an
idea
of
how
solar
power
can
offset
around
25%
of
power
usage.
Notice,
the
space
that
is
needed
to
produce
25%
of
annual
usage
exceeds
the
square
footage
of
the
2,000
square
feet.
Hoping
that
the
building
itself
will
have
a
larger
roof
than
that
of
what
is
actually
being
used
for
growing
crops.
We
can
also
size
the
system
down.
Again,
a
starting
point.
The
idea
of
offsetting
all
Carbon
Emissions:
By
growing
crops
locally,
you
are
not
emitting
greenhouse
gasses
that
would
otherwise
be
emitted
by
transportation
of
goods,
that
is
a
number
that
will
be
helpful
to
show
the
Green
Houses
as
having
a
“zero
carbon
footprint”.
The
electricity
that
this
facility
would
use
will
cause
the
release
of
348,966
pounds
per
year
of
carbon
dioxide
(which
promotes
global
warming).
Driving
386,696
miles
in
an
average
car
emits
and
equal
amount.
To
offset
the
yearly
emissions,
it
would
require
planting
872
trees
a
year.
This
solar
system
will
offset
the
carbon
emissions
by
25%.
Call
or
email
with
any
questions
or
comments,
Thank
you
for
the
opportunity,
Hans
Stullken
