Despite record-breaking heat and heavy rainfall, solar irradiance rose above average in key Asian markets. However, parts of Southeast Asia experienced cloudier, wetter conditions resulting in below-average irradiance.

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.

Choosing the right solar data can make or break project success. Our guide explains what to look for, from real-time cloud tracking to validated snow soiling models, and why Solcast leads in accuracy.

Make informed solar investments with accurate data. Our guide explains how to evaluate irradiance datasets, forecast accuracy, and PV modelling for better financial and operational outcomes.

Wildfire smoke and hurricanes cut solar production across the Midwest and Southeast in August, while the Northeast enjoyed sunnier conditions.

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.

A rare Atlantic Niña, polar anticyclone, and major dust storms created sharp swings in South American solar this winter.

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