Solar power for autonomous traffic systems, traffic control. Car2X, V2X, Vehicles, FIPV/VIPV

A multitude of products and devices have to be supplied with electricity independent of the grid. Either there is no grid connection available or the connection is too expensive and extravagantly. On top of that there are over two billion people on the earth without access to the regular grid.

But without electricity, many devices do not work today. Parking ticket machines, street lighting, as well as the entire communication via mobile phone or internet often only work based on a reliable power supply. Whether traffic systems, traffic control or Car2X/V2X, everything is possible everywhere thanks to solar. SOLARA solar modules and complete stand-alone systems, also known as stand-alone systems or OFF-GRID SYSTEMS, produce the necessary electricity in an environmentally friendly way without emissions. SOLARA also has the right solar modules for FIPV/VIPV. SOLARA has high-quality and affordable solutions for reliable solar electrification. For locations without a suitable power connection or remote regions, we have a self-sufficient solar power supply.

Many important applications - safely and reliably supplied with solar power!

The following are examples for commercial use of solar energy

Solar application explained and illustrated in detail on this page:

Car2X or Car-to-infrastructure supplied by solar power

The communicating vehicles require a corresponding solar infrastructure in towns and villages that can be supplied with solar power regardless of location.

Car2X or car-to-infrastructure powered by solar power are the future in modern mobility. The communicating vehicles need an appropriate infrastructure in cities and municipalities that can be supplied with solar power regardless of location.



Traffic lights can also be equipped with solar systems for this purpose so that they can communicate with cars in the future.

V2X-communication via WiFi hotspots by solar power

Communication between traffic lights and vehicles powered by solar power is independent of an electrical infrastructure. The traffic light systems are equipped with solar WiFi hotspots and are connected to a traffic control centre.

Communication between traffic lights and vehicles powered by solar power is independent of an electrical infrastructure. The traffic light systems are equipped with solar WiFi hotspots and are connected to a traffic control centre. This solar-powered technology is called V2X, where V stands for vehicle, and X for different devices or facilities. Via V2X, traffic lights can send data to cars via solar WiFi hotspots and also receive data via WiFi from vehicles. In addition, solar traffic lights send data to the so-called "mobility data marketplace", which contains all information about traffic jams, construction sites, traffic flows and provides much more.

Self-sufficient dynamic traffic control with solar panels - flexible control traffic situations

Traffic signs and speed indicators equipped with solar cells help to prevent accidents and to positively influence the flow of traffic. Lanes can be flexibly changed and displayed with solar.

Energy-efficient LED variable message signs equipped with solar systems enable road users to receive current traffic information on motorways and all other roads. Traffic signs and speed indicators equipped with solar cells help to prevent accidents and to positively influence the flow of traffic. Lanes can be flexibly displayed and changed with solar. Dynamic solar route information boards with a small solar system can display alternative routes at any location in the event of traffic jams or roadblocks. Measuring devices with solar cells as weigh-in-motion (weighing vehicles while driving) can also be used at locations without a power connection to monitor overloaded trucks.

Vehicles with integrated solar technology

Vehicle integrated photovoltaics (VIPV)

Electromobility and solar power are the ideal combinations. A solar system on the roof, carport, car park etc generates electricity for the electric cars in the immediate vicinity.


Electric vehicles with a solar system are optimum. That makes the e-mobile completely independent of charging stations. Of course, it is important to install sufficient solar cells on or near the vehicle. On commercial vehicles, such as trucks or lorries, there can be sufficient space for solar modules. The whole thing is then called vehicle integrated PV (VIPV).


The first steps towards vehicle-integrated photovoltaics have been taken by a consortium around the Institute for Solar Energy Research in Hameln (ISFH). The ISFH has equipped a light commercial vehicle with photovoltaics (VIPV). The solar cells on the vehicle generate solar power from sunlight. Solar power charges the car's high-voltage batteries. In this prototype, the solar power from the solar system is currently still used to extend the range of the vehicle. In this case, this means more range, less petrol/diesel consumption and considerable CO2 savings through vehicle-integrated photovoltaics.


The large body surfaces of a van or truck offer plenty of space for the installation of solar systems or solar modules. The photovoltaic surface or vehicle-integrated solar system not only charges the battery for the electric motor but also supplies electricity for the auxiliary units in the vehicle.

Vehicle integrated photovoltaics (VIPV)

Integrated solar cells or solar modules have been available for several years in car sunroofs (e.g. at Audi) or on truck refrigerator boxes. Integrated photovoltaics have proven themselves there as an additional energy source for air conditioning or cooling. These solar applications usually run on low-voltage 12 V or 24V.


Vehicle integrated photovoltaics (VIPV) already existed in the sixties. However, the special streamlined lightweight solar vehicles with integrated solar cells were a niche. However, vehicles with integrated solar technology had to prove themselves in competitions worldwide even back then. Universities, researchers and students were the main drivers of the small solar vehicles with integrated solar modules or solar cells.

Even in the small power range, reliability is a decisive criterion. Regardless of whether it is a mountain hut or a measuring station, a small solar system is often enough to ensure a power supply, even without complicated inverters. These small DC-coupled systems have the advantage that they can be set up quickly and transported easily, yet they are still able to provide energy for light, radio, TV, cooling, etc.


In addition, the systems form a solid basis for more complex systems. The modular design offers maximum flexibility. Additional components can be integrated step by step at any time as the energy demand grows.
