Troubleshooting and FAQs
Troubleshooting and frequently asked questions regarding Solcast data.
Within this section are the questions that we face the most.
Do you have logs?
At the moment, we do not offer any logging functionality for users to assist in troubleshooting should there be any issues.
We highly recommend that you record and log responses from request that you make, which will simplify the troubleshooting process should you encounter any errors.
These logs, when provided to us, enable us to isolate the issue and provide you with the best information as to the cause of the error, and the next best steps.
Should you be unable to provide these logs, don’t fret, just provide us with as much information as possible, and we’ll do our best to help you resolve any issues.
Can I have more than one API key for each department in my company?
No. One account is equivalent to one API key.
Will I have the same forecast from 8 am to 12 am and then another different from 12 to 16 pm? Why is that? This means that live data arrives with a delay period of 4 hours?
We use 2 different forecasting methods for different forecast horizons
- 0 to +4 hours: Nowcasts - we use our proprietary Nowcasting models, which track images of real clouds using optical flow models. These update every 5-15 minutes depending on location, in Europe, it is every 15 minutes. That means you get a new forecast every 15 minutes, which runs for the next 4hrs
- +4hrs to +14 days: NWP ensemble - we blend our Nowcasts into an ensemble of Numerical Weather Prediction (NWP) models which are trained on our live data and run from +4 hours to 14 days into the future
