Utility Scale Solar Forecasts
Solar power forecasting for solar farms or solar parks, delivered via API.
Rapid update solar power forecasts with global coverage
Forecasts at 5, 10, 15 or 30 minute time granularity, to +7 days ahead. Rapid update data at 10-15 minute resolution. Delivered via API & trusted by customers worldwide. Set-up your test site within minutes!
Share SCADA data and watch the forecast improve
Take advantage of our PV tuning technologies, which learn from your solar farm to individualise the forecast. POST your real-time SCADA data to the Solcast API or upload an extract of 3-12 months of historical data.
Proven use cases for our utility scale solar farm forecasting:
Avoiding penalties or meeting grid requirements
Management of attached energy storage
Management of microgrids or remote grids
Planning maintenance, commissioning or testing

Setup your own test site within minutes!
Get started now, and connect your solar farm with rapid-update forecasts with global coverage. All you need to get started are a few basic details about its location, capacity and tracking capabilities.
Once your utility scale solar site is setup in our system, you can send us an upload of recent historical data (3-6 months) from your solar farm to take advantage of our proprietary PV tuning algorithms to improve your forecasts.
