FAQs

Why am I getting zero power forecasts during daylight hours?

Check the power capacity, tilt or azimuth parameters in your Rooftop or Advanced PV Power request. You can see the documentation for these request parameters at https://docs.solcast.com.au.

Another possible reason may be that snow, dust or terrain shading is being included in the model and hence the predicted power output is significantly reduced.

How can I convert UTC to my Timezone?

We recommend using UTC to avoid changing timezones. You may want to validate Solcast data against one of your own data sets, and the difference between the dates in the two datasets is making a manual comparison difficult. You may be carrying out your comparison using Excel spreadsheets or files in csv format. If this is you, we have a tool for you that may help you out.

The above is a link to an excel spreadsheet that contains a tool to convert time series data retrieved from the Solcast API and applies a fixed offset to it.

The spreadsheet contains specific instructions on how to use the tool, but in a nutshell you would follow the below steps:

  1. Within the csv file containing Solcast API data, copy the column containing the time series you want to convert.
  2. Paste the time series into the first column of the solcast-timezone-converter spreadsheet
  3. Identify the fixed offset you want applied to the time series data (10 or -5, or some other offset). The tool will then apply the offset to the time series into a new column
  4. Copy and paste the updated time series data with applied offset back into your original csv file

Help, I’m getting 4XX errors?

401 Errors:

If you are receiving the error code: “This account has been locked”, it is likely that your account has been locked. This is primarily due to too many incorrect password attempts in the Solcast toolkit account login. If this is the case, please complete a password reset, and once successful, this will unlock your toolkit account and enable you to start making API requests again.

402 Errors:

Typical error messages are 402 Forbidden or 402 Payment Required.

This is likely caused by going over your quota of requests. In order to check, within the Solcast toolkit, select your user details at the top right, then within the dropdown, select Manage Subscriptions. Here you will be able to see your requests limit, and know if you have exceeded that value.

As per the screenshot above, you can also select view logs, or View request log (or View request log by location)

This will call our Service Stack tool to provide the specific API calls for this API endpoint, where it may provide further detail for troubleshooting.

403 Errors:

If you are seeing 'Forbidden' on my API requests.

Potential Issue 1: API Key error. We recommend that you go into the API key section and Regenerate Key.
Potential Issue 2: Another item to check is if you have spaces at the beginning or end of your API key, as that will cause errors.
Potential Issue 3: The API URL entered is incorrect, or has a character that is out of place (or missing values)
Potential Issue 4: You don’t have access to the API endpoint you are querying. If that is the case, please reach out to support@solcast.com.au to discuss your options.
404 Errors:

There are many possible situations where you receive 404 errors.

One of the potential reason could be the API key being entered incorrectly. In this case, the response status message will be ApiKey does not exist.

429 Errors:

If you are encountering 429 errors, we advise that you may be trying to send through too many requests from a single server at a given time. Please try waiting, or creating larger gaps between calls to alleviate this error.
