Spring 2025: Solar irradiation surges across Europe

Spring 2025: Solar irradiation surges across Europe

Western Europe has experienced one of its sunniest springs on record, with solar irradiation levels significantly exceeding historical long-term averages. Our proprietary solar irradiance data reveals that some areas recorded up to 50% more Global Horizontal Irradiation (GHI) compared to long-term (30 year) averages.

Why TMY data isn’t enough for PV simulations
Best practices

Why TMY data isn’t enough for PV simulations

While TMY datasets are useful for early-stage, pre-feasibility assessments, they are no longer sufficient for performance modeling and financial analysis. Just as we once moved from low-resolution to ultra-high-definition TV screens, the solar industry must now make the same leap and embrace high-resolution time series data as the new standard.

Being certain about solar radiation uncertainty
Best practices

Being certain about solar radiation uncertainty

In the context of PV yield simulation, uncertainty helps users understand the potential deviations in the results produced by the software they are using. Understanding these deviations plays a key role in selecting the optimal design of a power plant and in evaluating financial risks and return on investment.

Product news: Snow losses calculation now available in Solargis Evaluate

Solargis Evaluate now includes snow loss calculations, providing developers with a more realistic estimate of energy production in regions affected by snowfall. This is one of the latest enhancements in the new Solargis Evaluate platform, launched in early 2025.

The solar sector needs a reliable database on the technical specifications of PV components

The solar sector needs a reliable database on the technical specifications of PV components

While the growth in PV has brought fast development of a variety of products to the market, it has also created a new problem: It’s becoming increasingly difficult for project developers to manage and accurately evaluate the technical specifications of the modules, inverters and other components of a PV power plant.

Tackling the inaccuracies of PV performance predictions for bifacial solar systems

Tackling the inaccuracies of PV performance predictions for bifacial solar systems

Bifacial photovoltaic (PV) modules dominate in modern solar projects, as they are more efficient, capturing sunlight on both sides of the cells, and generating more energy than monofacial PV modules. However, the shift to bifacial photovoltaics requires a different approach to feasibility evaluation compared to traditional monofacial technology.

Introducing Solarmaps: Enhance your PV performance analysis with interactive maps

At Solargis, we’ve just released Solarmaps: a new solution designed to empower PV power plant portfolio managers, operators, and analysts. Solargis Solarmaps provides timely and accurate insights into the monthly availability of solar resource, air temperature, precipitation, and wind speed: key factors that influence PV power plant performance.

Extreme weather and variability are testing the limits of solar software

Extreme weather and variability are testing the limits of solar software

The higher frequency of the extreme weather puts growing pressure on the PV industry to design power plants that can withstand harsher conditions. Beyond this, developers must consider the potential losses from the extreme weather events and the likelihood of their occurrence.

Are you still juggling multiple applications for PV evaluation? You don't have to
Best practices

Are you still juggling multiple applications for PV evaluation? You don't have to

Managing multiple applications for different stages of PV project evaluation is both costly and inefficient. While most of the developers have long accepted this as the norm, the solar industry needs a comprehensive solution that brings all functionalities together in one solution.

Solar irradiation difference map of 2024: Another year of extremes

At Solargis, we conducted our yearly analysis of global horizontal irradiation (GHI) and evaluated the difference for 2024 from the long-term average (LTA). Our findings reveal notable decreases and increases in solar irradiation across the globe, while GHI in other regions oscillated around the long-term average.
