Energy Production and Distribution

Solar power plant design and engineering

Sustainability, cost efficiency and scalability

Solar power plants use the sun's energy and can help fight climate change. Investment costs have been significantly reduced in recent years, which improves cost-effectiveness. In addition, maintenance costs are low because there are no moving parts.

We can support our clients from the early development phases up to the final project implementation phase. Our engineers use industry recognized software tools for the study, simulation and design of photovoltaic systems starting from the meteorological data, up to the system configuration, conceptual design, system performance simulation, energy yield calculation, uncertainty analysis and financial modeling.

We carry out the analysis and optimization of cost-effective, reliable microgrids, energy storage and hybrid energy systems either grid connected or off-grid applications. In addition to industry standard software tools like PVsysts and Homer Pro, we can complement the analysis with our home-made tools for data analysis and financial evaluation, as well as other specialized engineering tools used in the design of big infrastructure projects.

Gruner supports clients for the design and construction of solar and hybrid power plants – from the preliminary study to construction management.

Thanks to our experience and capabilities in the design of medium and high voltage electrical systems including substations, transmission, and distribution systems, we can provide a full range of engineering services to support the development of solar photovoltaic and hybrid renewable energy systems:

  • Site Assessment and Site Selection Support
