Global Solar Irradiance Forecasts and Historical Datasets

When we first launched the Solcast API in early 2017, the Solcast team was excited to learn more about the market for historical and forecast solar irradiance and solar power data services. Now, 18 months later, with nearly a thousand users across five continents, we see no better way to launch our company blog than by thanking those users for their commitment to the integration of solar energy, and for being such forward-thinking early adopters of the Solcast API. So - Thank you!

Forecasting Collective Solar PV Ramping Events

When a few hundreds of megawatts of solar generation undergoes a negative ramp event, the energy markets see a sudden jump in the regional demand and local distribution networks will see changes in network loads/voltages in their control rooms. This leads to challenges managing our electricity markets and networks in areas where large amounts of solar are installed.
