Wattway Solar Road

Solar road autonomous generator


The solar road autonomous generator solution is a trafficable photovoltaic surfacing designed to autonomously power equipment near the roadway.

This is a breakthrough innovation that provides road networks with a second function: the production of renewable energy. Solar road panels are used to power any type of energy-consuming equipment located near the road. The solution acts as an autonomous generator (without backup to the national grid) for the equipment, thus meeting the needs of customers in terms of safety and communication by creating new autonomous source. The generator makes it possible to avoid network connection costs in remote areas, without the need for heavy construction work. With a few panels, this solution makes it possible, for example, to power traffic signs and speed limit signs, remote monitoring equipment or standalone street lights with the possibility of adding presence detection.
