When evaluating potential partners, it is essential to apply rigorous criteria—something that can be difficult without a solid understanding of geoscience and engineering.
The size of PV projects and increasingly complex market conditions in which they operate demand greater sophistication in plant performance modelling. Marcel Suri explores the datasets that will help improve the accuracy of PV output estimation and reduce the gap between projected and actual performance.
In the face of extreme weather, high-resolution, real-time data is becoming increasingly critical to building climate-resilient PV systems, writes Marcel Suri of Solargis.
The PV industry needs to continually build its position with investors, lenders, regulators and grid operators who want to rely on PV as a solid partner on the path to the energy transition. The solar data industry doesn’t need more assumptions. It needs science.
When selecting solar resource data for PV projects, many in the solar industry still rely on outdated or questionable practices. One especially concerning practice is the use of multiple datasets—or worse, mixing them—to artificially enhance financial attractiveness for investors, banks and stakeholders.
Solargis provides high-resolution ‘Time Series’ data that enables developers to analyse long-term patterns of cloud cover and other weather-related risks, said Marcel Suri, CEO, Solargis, in an interview with Energetica India Magazine.
“It takes time, and it takes courage!” begins Marcel Suri, CEO of Slovakian data analysis firm Solargis, speaking to PV Tech Premium about changes in technical specifications in the global solar industry, and how this can impact cybersecurity concerns.
Heat domes worsen solar underperformance and lead to price gaps; Solargis calls for attention to more innovative forecasting tools.
An analysis by Bratislava-based solar irradiance firm Solargis has indicated the impact of a sunnier than usual Spring on solar generation in Europe.
The recent heat dome has exposed vulnerabilities in the operational and trading strategies of utility-scale solar projects, according to new analysis by Solargis, the industry’s trusted source for solar data and software.
Their [Solargis] report highlights the critical need for improved forecasting, project evaluation, and battery storage capacity coupled with large-scale solar.
According to a new analysis by Solargis, rising ambient temperatures and volatile real-time energy markets are testing the limits of current forecasting tools, storage strategies, and asset resilience – especially in merchant-exposed markets.
Western Europe has experienced one of its sunniest springs on record, with solar irradiation levels significantly exceeding historical long-term averages, according to newly released solar irradiance data by solar data and software specialists Solargis.
Marcel Suri explores the datasets that will help improve the accuracy of PV output estimation and reduce the gap between projected and actual performance.

Fluctuations in solar power generation and energy prices in the US during July’s heat dome highlight the need for more nuanced data in project management, and the importance of battery storage projects in balancing the grid.
Technological and financial advances in the PV industry demand greater precision in PV simulations, but the datasets used for modelling often lack the necessary sophistication. Marcel Suri, CEO of Solargis, explores three areas where new standards could help underpin greater efficiency, accuracy and market resilience.
Spring 2025 saw up to 50% above-average solar irradiance in Western Europe, driving record-breaking UK solar generation – up 42% year-on-year, saving £600 million in fuel costs.
Solar irradiation in Western Europe has increased by 50% above-average during Spring, according to an analysis by weather data and software provider Solargis.
Western Europe experienced one of its sunniest springs since records began, with solar radiation significantly above historical long-term averages. This information was reported by Solargis s.r.o., a consulting firm based in Bratislava, Slovakia.
The lack of standardisation and verification in the technical specifications of photovoltaic (PV) components is a challenge that is often underestimated in the solar industry.
During its booth visits, the TaiyangNews team stopped by Solargis, a Slovakia-based provider of solar and meteorological data, along with advanced software solutions for project performance evaluation and forecasting.
Bifacial technology requires more advanced simulation methodologies and more accurate, detailed datasets. To keep up with technological advancements in PV modules, the solar industry must evolve and move beyond legacy approaches that fail to support innovation.
As India accelerates toward its 2030 renewable energy target, combining advanced algorithms with granular solar data will be essential for unlocking the full potential of its solar industry.
As technology advances, climate variability intensifies and financial requirements grow stricter, relying on outdated assumptions and low-resolution data is no longer viable.
