The uniquely-designed solar system, wayfinding sign solution, comprises of integrated PV panels to ensure light is captured from all angles, an intelligent Ni-MH ( nickel) battery, motion-detecting PIR sensors and LED lights. The LED runs continuously at a low level to ensure that the bollard itself can be seen from a distance, and the other, a downlight reflector, is activated when proximity of movement is sensed by the PIR sensors which illuminates the pathway.

As the bollard is solar powered by it’s own integrated PV panels, trenching and running costs associated with mains powered solutions are eliminated and maintenance costs are drastically reduced.
The Solar post control system uses a four channel dynamic boost algorithm to maximise the power generated from each individual solar panel. During the day the light tracks across the Solarpost, illuminating and shading the panels. To capture energy efficiently from direct and indirect sunlight, the optimum power point of the panels is calculated in real time and the charge taken from the panels is adjusted, harvesting the maximum power from each panel. The battery is charged throughout the day from the energy harvested from the solar panels. The Solar post control system has battery management technology which mitigates full discharge by reducing the LED brightness till there is sufficient ambient light to charge. To maintain battery levels during transportation a low power mode can be initiated by briefly placing a magnet against the Solar post, once installed the magnet is used again to activate ready for use.
The Solar post control system monitors the ambient light levels, anticipating the transition from day to night. The automatic transition allows for seasonal changes in light levels. During the night a high efficiency 180 lumens- per-watt white LED illuminates. The brightness of the LED is regulated by a pulse-width-modulation driver circuit, the LED remains at a low light level until activated by the passive infrared (PIR) sensors. The PIR sensors have a detection range of up to 5m, on approach the LED brightens for 10 seconds, gently dimming to the low level. The Solar post control unit is fully sealed and uses IPX7 connectors.
The standard product has a base plate mounting but there is an option also for a more cost-effective root mounting fixing that can be buried. We can send a technical specification on this if required.
This product does comply with the new requirements for "bat-friendly lighting". Bats can not feed at night with light pollution in an upwards direction.
The LED runs continuously at a low
level to ensure the post can be seen from a distance and the PIR sensor activates the LED to full brightness on approach.
