Solargis news

Based on our proprietary Solargis data, we are able to track and analyse unusual patterns in solar resource availability. At Solargis, we run these analyses every month, with global coverage. In Japan, South Korea, and eastern China, we observe some of the strongest positive anomalies (regionally over +40%), while Taiwan and the northern Philippines experienced notable deficits (below -35%).

The recent heat dome that enveloped large parts of the Midwest, Northeast and Southeast of the U.S., including states like North Carolina and Maine, has exposed vulnerabilities in the operational and trading strategies of utility-scale solar projects. These extreme weather conditions had direct operational consequences.

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.

We’ve just added another layer of precision to Solargis Evaluate. Following the recent launch of snow loss calculations, soiling losses are now also part of our energy yield simulation toolkit – helping developers, investors, and technical advisors model real-world PV performance more accurately.

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.

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.

We’re introducing eight new map layers in Solargis Prospect, designed to provide quick insights into factors affecting the performance, durability, and risk profile of photovoltaic (PV) systems. These new layers offer essential data for PV project engineers, developers, and financial planners, helping them make informed decisions about site selection, system design, and long-term investment strategies.

Today, we launched Solargis Evaluate 2.0, the next generation of our Evaluate solution. The new Evaluate is a more advanced, cloud-based platform for complete PV project design and evaluation, equipping project developers and industry experts with all the tools needed to tackle the growing complexity of modern solar projects.

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.

This innovative Solargis Monthly Report enables portfolio managers and PV site operators to optimize operations and deliver clear insights to board members, senior management teams and C-suite decision makers about the performance of their PV projects.

Solargis has analyzed the annual performance of solar irradiance for 2023, revealing the trends and variations of solar irradiance across the globe.

New analysis by Solargis reveals that the variance between modeled solar irradiance and actual measurements is more pronounced in tropical regions than in temperate and subtropical zones.
