Integrated photovoltaic and electric vehicle charging solution for a multi-energy service station – Case 2.

Read the article

Located in a highly frequented area near residential and shopping zones, the OMV service station in Trnava serves a large and diverse customer base. Anticipating the growing demand for electric mobility while maintaining its existing fuel services, OMV Slovensko aimed to progressively transform the site into a modern, multi-energy service station with a strong focus on sustainability and operational efficiency.

Project overview.

TSG Slovak Republic supported OMV Slovensko in a two-phase project combining on-site renewable energy generation and high-power electric vehicle charging infrastructure.

The first phase focused on the installation of a rooftop photovoltaic system to support station operations with clean, renewable electricity. Several months later, the second phase included the installation and commissioning of fast electric vehicle charging stations, responding to the increasing number of electric vehicle users in the area.

This step-by-step approach allowed the service station to evolve from a traditional fuel site into a multi-energy hub while maintaining continuous operation and customer accessibility.

The solution delivered by TSG.

We delivered a turnkey solution covering the full project lifecycle, from design and equipment supply to installation, testing and commissioning.

In the first phase, a photovoltaic system was installed on the station roof, consisting of 58 SolarEdge solar panels, each rated at 550 W, supported by 30 power optimisers and one inverter. The system enables efficient on-site energy generation and can be monitored in real time via the MySolarEdge application. SolarEdge safety features, including SafeDC™ and arc-fault protection, contribute to safe and reliable operation.

In the second phase, we installed two Alpitronic Hypercharger HYC300 DC fast-charging stations, each equipped with two connectors, allowing up to four vehicles to be charged simultaneously. The chargers provide up to 300 kW of power with dynamic load distribution and are designed for high reliability, durability and ease of use in demanding outdoor environments.

All installation, commissioning and testing activities were carried out by trained and manufacturer-certified TSG technicians, in compliance with strict safety standards.

Results and Impact.

The service station now operates with both photovoltaic energy generation and high-power electric vehicle charging fully in service, offering customers a broader range of energy options.

The integrated solution supports OMV Slovensko’s sustainability objectives by reducing reliance on external electricity sources, lowering CO₂ emissions and enhancing energy resilience. At the same time, the availability of fast-charging infrastructure improves accessibility for electric vehicle drivers and contributes to the development of charging infrastructure in Slovakia.

The project demonstrates how existing service stations can be successfully upgraded into modern, multi-energy mobility hubs while meeting evolving regulatory and market expectations, including the requirements of the AFIR framework.
