RSRG has developed a comprehensive pilot concept to reduce CO₂ emissions on construction sites. It consists of:
- a solar roof,
- an energy storage unit,
- an HVO generator, and
- an online tool.
The solar roof not only serves as an energy producer, storage, and supplier, but also provides shade on hot days. The online tool allows production and consumption data to be monitored in real time.
A mobile storage unit increases capacity and offers additional sockets for higher connection loads. The generator is used only as a backup system to avoid power shortages when solar energy is insufficient.
Two combination types are available:
- Basic combination: For standard small construction sites with office containers and smaller consumers (e.g. battery-powered tools).
- Extended combination: With higher system capacity and connection power. Designed for sites where larger equipment (e.g. rollers – see photo) must be charged or entire container villages supplied.
The various battery systems.

Another system includes mobile folding PV units that also utilize solar energy, plus a matching energy storage unit. This system reliably powers, for example, battery-powered wheel loaders. Grid electricity serves as backup, sourced 100% from green power.
