Most distributed solar operators assume meeting their TMY target means their assets are performing well. Popular Power's data across 500 MW says otherwise — the average site is leaving 16.7% of its weather-adjusted potential uncaptured, worth ~$30,000 USD per MWp annually. Here's how climate-adjusted tracking reveals what conventional benchmarks miss.

You can now estimate PV generation losses from soiling using two industry-standard models, with Solcast-supplied precipitation and particulate matter inputs built in.

How did weather impact global solar production in 2025? Use our interactive map to explore irradiance anomalies, La Niña effects, and regional solar generation trends worldwide. Explore global solar irradiance trends, anomaly maps, and daily generation variability to see how weather shaped solar production in your region.

Widespread clear skies boosted Australian solar in January, though smoke, dust, and Tropical Cyclone Koji caused localised reductions.

Winter Storm Fern drove widespread cloud and cold across North America in late January, reducing solar irradiance and PV generation in affected regions.

The shift from centralised thermal generation to distributed renewable generation is fundamentally changing grid architecture. Managing this transition isn't just about building capacity - it requires a new data layer: granular, scalable forecasting that provides the observability to operate thousands of independent generators as a coordinated system.

January saw above-normal solar across East Asia under weak La Niña, but storm-driven cloud and rain reduced irradiance in the Philippines.

Storm systems and late-month snowfall reduced solar irradiance across much of Europe in December 2025, while central regions benefited from clearer conditions

December irradiance anomalies followed a classic La Niña setup, with a ridge over the Southwest driving strong solar gains and deficits across northern regions.

Analysis by the Electricity Authority revealed forecast errors were affecting spot prices by up to $273 million annually. After examining global approaches, they implemented a hybrid forecasting arrangement - and selected DNV as the centralised forecast provider following an 8-week competitive trial.
