From assessing the reliability of PV power models to minimising tool-hopping and knowing which solar tools to trust, our experts explore the biggest challenges solar teams raised at RE+ 2025 - and how to navigate them.

Persistent high-pressure systems drove record sunshine across Europe in August 2025, lifting PV output above average—except in storm-hit Mediterranean regions.

DNV’s SolarFarmer API is now integrated into Solesca, helping solar developers deliver lender-grade energy yield assessments directly in the design stage.

Solcast is now part of DNV’s Green Data Products, a trusted suite of renewable energy solutions. Together, we deliver bankable data and advanced power models to support financing, forecasting, and operations across the renewable lifecycle.

Seasonal models show strong solar irradiance forecasts for Europe and North America in H2 2025, while other global regions face mixed or poor trends.

Early 2025 brought sunnier skies to Europe, China, and western North America, while Southeast Asia and Canada saw cloudier conditions.

Solcast’s high resolution solar data is now embedded in Solesca, enabling faster, smarter, and more accurate solar asset design, all in one platform.

High pressure delivered solar records in the UK and Germany. Meanwhile, Eastern Europe struggled with heavy clouds and 25% irradiance loss.

‍

Canadian wildfires reduced irradiance by up to 10% across cities like Toronto and Minneapolis—with effects seen as far as Western Europe.
