The challenge
Rural mobile care services struggle, beyond the labour shortage, with high fuel costs — average daily distance is around 150 km per vehicle. The goal was a holistic, sustainable energy and mobility concept involving local citizens.
How we delivered it
- 01
Consulting & planning
Calculation of the economically optimal PV and charging-point expansion. The resulting conversion roadmap was the basis for technical delivery.
- 02
Renewable energy
In May 2024 two PV systems totalling 30 kWp were installed on the company premises.
- 03
Charging infrastructure
Eight 11 kW charging points were installed on the company premises.
- 04
Fleet transition
The existing fleet of 15 petrol vehicles is being fully converted to electric step by step.
- 05
Citizen participation
Through profit-sharing rights, employees and patients participate actively in the sustainable transformation of the care service — with attractive interest opportunities for investors.
What the project achieves
- Cost reduction: fuel operating costs fall by 65% per year.
- Attractive return: average internal rate of return (IRR) of 40%.
- Fossil fuel savings: 32,850 litres of petrol per year.
- Climate protection: 77 t CO₂e p.a. from fleet change + 13 t CO₂e p.a. from on-site PV (34 MWh at 380 g/kWh CO₂e).

Pictures from the project
„Employee participation combined with the shift to electric mobility is a double win for us: we cut our running costs massively and offer our employees real added value through participation."
Takeaway for your project
This model fits if you are a regionally anchored company looking to cut energy and mobility costs while deepening the relationship with employees and customers.
Explore the technical design and the participation model
Open this project's design in the Energy Scenario Studio or recalculate the participation model — pre-filled with this project's figures.
Technical design: 30 kWp PV + 8 charge points
Combustion fleet versus e-fleet with midday PV charging — hourly balance, self-sufficiency and 20-year total cost.
- 30 kWp PV
- 8 × 11 kW
- 10 BEV
Participation: EUR 55,000 via citizen profit rights
PV and charging infrastructure without equity: liquidity advantage and break-even versus direct investment.
- 55.000 €
- 6,25 % p.a.
- 3 J.
All figures are project-based reference values and can be adjusted freely in the calculator.
