Posted on 10 Jun 2025

OpenWeather has announced the release of Solar API 2.0, a significant upgrade to our highly-regarded solar data service. This next-generation API delivers a substantially expanded dataset and enhanced accuracy, empowering developers and businesses with even more precise insights for solar energy applications. This API can be accessed, at no additional cost through the OpenWeather Solar Irradiance API and Solar Panel Energy Prediction products. Solar API 2.0 represents a significant advancement. We've enhanced the API to provide precisely what you need, with new and improved solar and panel parameters, empowering you with a more robust and comprehensive understanding of solar potential. The new version boasts a significantly expanded dataset, including:

  • Solar parameters: avg_irradiance, max_irradiance, and irradiation.
  • Panel parameters: avg_irradiance, max_irradiance, irradiation, avg_power, max_power, and energy.

In addition, the Solar API 2.0 offers remarkable flexibility with data available in time steps of 1 day, 1 hour, and 15 minutes. Users can also access data for both clear and cloudy sky conditions, all with global coverage and accessible via a streamlined API format.

The enhanced Solar API 2.0 is a testament to the OpenWeather commitment to providing the most accurate and comprehensive weather data for the renewable energy sector. This enhanced API will enable users to build more efficient solar energy systems, optimize panel performance, and make smarter investment decisions, all while maintaining the same affordable pricing structure.

OpenWeather will continue to support Solar API 1.0, ensuring a smooth transition for existing users. Comprehensive and updated documentation for Solar API 2.0 is available at https://openweathermap.org/api/solar-irradiance and https://openweathermap.org/api/solar-panels-and-energy-prediction-2.
