Two pcs of 7AH batteries are available for Gate Opener and the operational time of
the batteries depends upon the capacity of the batteries. Greater the capacity
of the batteries better will be the performance in cloudy days. The solar energy
conversion efficiency may vary with the installation places and weather
conditions. For better receiving of sunlight install the solar panels in open
areas clear of obstructions such as trees and buildings which tend to block the
sunlight. The solar panel must be placed with its surface facing in the
direction of maximum acquisition of sunlight i.e. south facing in the northern
hemisphere and north-facing in southern hemisphere.
