Solcast is one of DNV’s Green Data Products

Data you can trust. From feasibility to forecasting

As the renewable energy sector accelerates, the need for reliable, bankable data has never been greater. As a part of DNV, the Solcast API, and the Solcast team, are now one of DNV’s green data products – a suite of trusted solutions powering automation, transparency, and decision-making across the entire renewable asset lifecycle, based on DNV’s expertise and knowledge in trusted power modelling.

This isn’t just some new products. It’s about delivering even more accurate, trusted, and practical data tools for the solar and wind industries.

Data: The backbone of the Energy Transition

As the world shifts from thermal-based systems to renewables, data is the driving force behind reliable, efficient, and scalable clean energy. DNV’s Green Data Products are built specifically for this transition, turning complex performance data into clear, actionable insights.

From feasibility to operations, our products provide:

• Bankable actuals and power models for financing, due diligence and performance reporting.
• Accurate weather and power forecasts for operations, trading and optimisation
• Digital-first tools to improve efficiency, anticipate risks, and unlock value at every stage.

Solcast: Trusted forecasting for renewables

The Solcast API continues to provide the fast, flexible solar and weather data developers rely on. Now, with DNV’s global forecasting team joining forces, you can expect even greater accuracy and bankability.

Our forecasters are applying decades of renewable energy experience to enhance our premium PV power and wind power models. With a stronger focus on wind power accuracy and modelling, with more new improvements coming later this year – supporting better integration and performance of renewable asset portfolios worldwide.
