Solar Panel and Gate Activity Chart
The table and map illustrate the maximum number of gate cycles to expect per day in a particular area
when using from 5 to 30 watts of solar charging power. The gures shown are for winter (minimum sunlight)
and do not account for the use of
any accessory items.
Accessories connected to your
system will draw additional power from
the battery and will require additional solar
panels.
NOTE: UP to 250 ft. of 16 gauge dual
conductor, stranded, direct burial wire may
be used to allow installation of solar panels in
direct sunlight.
