ELECTRIC FENCE
35
You need 10 watts for every one output
joule of your energizer. Up to 20 watts per
joule is sometimes used in northeast USA.
Solar panels should always face south.
Use a deep cycle type battery; the best
values can be found locally.
FREESHIPPING
Solar Panels
Improvements in efficiency and lower costs
have made powering your fence with solar
affordable and easy. Simply match the size
of the solar panel with the energizer. Our
Solar Panels have a rugged aluminum frame,
polycrystalline panel and approximately 18”
cable. Five year manufacturer’s warranty.
CHOOSING A SOLAR PANEL
Your solar panel should match the size of
your fence. For each joule of output, allow 7
watts of solar panel for high sunlight areas
and 10 watts in low sunlight areas.
Example: 3 Joule Energizer = 30 watt solar panel.
STEP 1
Calculate what your charger (load) needs to
run for a day. Example is for a 3-joule energizer.
How to Calculate the Ah per day needed:
Volts x Amps = Watts
12
volts x .29 Amps = 3.48 watts
Wh= 3.48 W x 24 hours = 83.52Wh
Determine Amperage Hours
A=W/V
Ah = 83.52WHr/12v=6.9375 Ah per day
STEP 2
Find out how much sunlight you get in your
location:
Solar insolation map for peak sunlight hours
STEP 3
Calculate which solar panel will provide the
Ah per day you need.
Divide Ah from step 1 by the number of Peak
Sun Hours per day.
6.9375
Ah/3.68Hr=1.885A
This means that a panel which produces 1.8A
is what you need.
Determine panel size:
A = Watt/Volt
Watt=Volt x Amp
______
= 12 V x 1.8 A
=21.6 watts (always add 20% to take account
real world conditions)
=25.92 watt (round up) = 30 Watt panel
