Solcast is a renewable energy data and forecasting platform within DNV Green Data Products, providing irradiance, wind, and weather data, as well as power forecasting models for solar, wind, hybrid assets, market, and grid use cases. It is positioned not as a general-purpose weather API, but as professional data infrastructure for renewable energy assets throughout feasibility assessment, financing, construction, and operational dispatch.
Based on the main content, Solcast provides historical time series from 2007 to recent dates, Typical Meteorological Year data for 2007–2025, Live Data updated every 5 minutes, and Forecast Data from now through the next 14 days. Data and models are available via API, Web Download, and direct delivery, in formats including JSON and CSV. Its power models cover Rooftop PV, Advanced PV, Premium PV, Premium Wind, as well as portfolio, market, and grid models. Advanced models can be trained using generation data or SCADA data, and support probabilistic outputs such as P10–P90, availability and curtailment schedules, multi-source NWP blending, and more.
The pricing page is mainly based on “Request a quote” and does not publish specific prices. For trials, users can make a limited number of historical, live, and forecast requests for their own locations, and can also use some model requests at unmetered locations. In addition to API and web downloads, delivery options mentioned include FTP, SFTP, API push, and cloud storage buckets, making it suitable for integration into existing energy operations systems.
Its strengths are deep vertical specialization, high data frequency, end-to-end coverage from resource assessment to operational forecasting, and supporting resources such as API documentation, SDKs, a knowledge base, Changelog, validation materials, and research content. DNV’s backing also strengthens trust for bankable assessments and procurement in large-scale projects. The downsides are that pricing is not transparent and requires sales engagement; Premium models depend on customer production data or SCADA data, so deployment is not fully plug-and-play; and the pages do not provide details on open source, self-hosting, or specific programming-language SDKs.
Solcast is better suited to solar/wind developers, asset operators, grid or market dispatch teams, and energy SaaS teams, rather than general weather app developers. Access from China and supported payment methods are not stated in the main content, so they are assessed as unknown. If procurement is constrained by network access, compliance, or payment workflows, alternatives such as Meteomatics, Tomorrow.io, OpenWeather, NASA POWER, NREL NSRDB, and ECMWF/Copernicus can also be evaluated.
