This solar isola�on map recreated courtesy DOE.
The chart is based on a 20 Wa� (24VDC) solar panel system with
SwingSmart powering a 12 foot (3.6m), 750lbs (340kg) gate with
the following peripherals a�ached:
One low current multi-code radio receiver
Two HY-5B vehicle detectors
The number of amps that the peripherals draw coupled with the gate travel
occurring throughout the night determines the battery capacity required.
The number of amps that the peripherals draw coupled with the gate travel during
the day, determines the solar panel size needed.
NOTE:
HySecurity provides a 50Ah battery option for sites where high gate travel and
inclement weather are an issue. For sites of this nature, consider at least 40W system. A
40W system doubles the feet of gate travel/day that is shown in the chart above.
