Enthusiastic experts working at Solargis
CEO & Co-founder
Marcel is an entrepreneur and solar energy specialist with a background in geography. Holding a PhD in Geoinformatics, he began his career as a researcher at the Institute of Geography, Slovak Academy of Sciences.
In 2001, he joined the European Commission’s Joint Research Centre in Ispra, Italy, to work in photovoltaics, helping to develop and promote the PVGIS software. In this role, he combined his expertise in geoscience with renewable energies.
His journey led to the founding of GeoModel Solar, where he acted as Managing Director before becoming CEO of the company rebranded to Solargis.
Under his leadership, Solargis has emerged as a key player in providing solar resource and weather data, along with photovoltaic software and consultancy services.
Through a dedicated approach to innovation, Marcel continually pushes for enhanced standards, aiming to boost the efficiency of the solar energy industry and reduce weather-related risks.
CTO & Co-founder
Tomas has a background in geography, earned his PhD in Cartography and Geoinformatics from the Institute of Geography, Slovak Academy of Sciences in Bratislava, Slovakia.
In 2006, Tomas joined the European Commission’s Joint Research Centre in Ispra, Italy, where he significantly contributed to the development of the PVGIS online portal, broadening the reach of solar resource data and software.
Transitioning from public research to the private sector, Tomas served as Technical Director at GeoModel Solar, before taking on the role of Chief Technology Officer at Solargis.
Since 2010, he has been leading the development and operation of Solargis' global solar resource and meteorological database, alongside online simulation, management, and control solutions for solar photovoltaics systems.
Since its inception, Solargis has leveraged satellite image processing and atmospheric and meteorological models to develop proprietary algorithms and deliver high-quality solar data and energy evaluation software.
After years spent in research around Europe, two Slovak scientists—Marcel Suri and Tomas Cebecauer—started to see the increasing gap between scientific theory and engineering applications.
Their dedication to geoscience and solar research and the creation of sophisticated models began, at one point, intertwining with increasing market demand for such solutions.
In 2010, Marcel and Tomas established a venture to apply and commercialize the research outcomes, aiming to support the industry in developing and operating solar power plants more efficiently.
First known as GeoModel Solar, in 2016 the company changed its name to Solargis.
As the years progressed, the founders expanded a multidisciplinary team of specialists. They increased the capacity of technical and customer engagement teams to meet the demand for investment-grade solar and weather data and provision of specialized solar energy software and advisory services.
The Solargis team is equipped with the knowledge and experience accumulated from supplying Solargis data for tens of thousands of large-scale projects worldwide and working with solar and meteorological measurements at over 1500 locations.
These insights help the team profoundly understand the challenges stakeholders face across the solar energy value chain.
Solargis' commitment to quality and innovation has earned it recognition and trust from organizations and individuals all around the world.
1990-2008 | Marcel Suri and Tomas Cebecauer work as geoscientists at research facilities in Slovakia (Slovak Academy of Sciences in Bratislava) and Italy (EC JRC in Ispra). |
2008 | In response to the growing demand from the solar industry for quality solar irradiance and meteo data, development activities started within GeoModel and moved to GeoModel Solar in 2010. |
2010 | ClimData (the predecessor of Solargis Evaluate) is launched with the goal of providing access to global solar radiation and meteorological time series data starting in 1994. The database offers access to Typical Meteorological Year data based on in-house developed methodology. |
2011 | pvPlanner and iMaps software online apps are launched (the predecessor of Solargis Prospect), providing access to the first high-resolution database of solar and meteorological parameters, maps, PV energy simulation, and reporting solutions. |
2012 | PVSpot (the predecessor of Solargis Monitor) is launched. For the first time, solar power plant operators get and use satellite data almost in real-time, with a delay of only a few hours. |
2013 |
Solargis database available globally. |
2013 |
Solargis' satellite-based solar radiation model is explained in a book on Solar Energy Forecasting and Resource Assessment. The solar models are being constantly reviewed and improved. |
2014 |
Solargis Forecast is launched, based on the processing of data from global numerical weather prediction models adding short-term forecasts to the spectrum of Solargis solutions and thus covering the full lifecycle of solar power projects. |
2014 |
A satellite-based solar radiation data validation study by the University of Geneva has been published. The study, in a transparent and scientifically rigorous approach, identifies Solargis data as the most accurate. More independent studies published later confirmed these findings. Solargis data is validated at 1500+ public and private measurement sites. |
2015 |
Solargis methodology on TMY data is published in Energy Procedia. The TMY data based on this methodology became an industry standard. Solargis delivered TMY data for approx. 10,000 large-scale projects yearly. |
2015 |
Nowcast service provides very short-term forecasting for the next 3 hours based on the processing of geostationary satellite images. This method became an integral part of Solargis Forecast services. |
2016 |
Solargis methodology on solar model site adaptation has been published in AIP Conference Proceedings. The method is routinely used for large-scale projects and has become an industry standard. |
2016 |
GeoModel Solar rebranded to Solargis. |
2017 | Launch of the Global Solar Atlas developed by Solargis as part of the World Bank Group’s ESMAP initiative. |
2018 |
Solargis API is released. |
2019 |
The Solargis Prospect app is launched, making the pre-feasibility phase easier and more reliable. The app also features a set of high-resolution maps that help users understand the geographic context of solar, meteorological, and environmental conditions relevant to the development and operation of solar power assets. |
2021 |
Solargis joins the European R&D initiative SERENDI-PV to improve the lifetime, reliability, performance, and profitability of PV power generation and increase the penetration and integration of photovoltaics in Europe. |
