Streetlight from Priess Solar standalone solar-columns. By an access road around a greenhouse complex, three 8-metre Plectre Sun columns were installed in January 2021. The access road is located in a three-road system and is angled at 90 degrees behind the greenhouses. Plectre sun columns have been placed at the 90-degree bends and at the end of the road in order to alert traffic to the curves in the road.
Each Solar column is remotely monitored via the Priess cloud log service, enabled by internet access (GSM access) on the Master control units. This means a service team will be warned in the event of any operational failures and will be able to then act accordingly as soon as a problem occurs.
Plectre Sun triangular column in aluminium, with the luminaire arm mounted at a height of eight metres.
The column is fitted with three solar modules vertically mounted on all three sides, giving the pole a total of 414Wp solar power. The LED luminaire is 45W maximum with a lumen output of 5400Lm.
Battery charging, light operation and data logging are all handled by the solar control unit, the LCC, which is among the world’s most advanced controllers for solar light operation. The LCC controller enables stabile operation during the winter months, with a 365-day individual light plane, ensuring balance between energy produced and energy consumed.
