Frequent asked questions

The subscription and one-time purchase options outlined on this page are for use of data outputs within the customer's organisation. In case you want to share data with your client, consultant, or sub-contractor, you need to seek prior written consent from Solargis before sharing data. 

For publishing Solargis data in the public domain, or for the inclusion of data in tender documents we offer multi-user and/or open access for an add-on fee. For further details or any questions, please contact us.

Unused data credits can be carried over to the next subscription period upon renewal of the subscription. Please note that there is a maximum limit on the number of credits that can be carried over. The maximum limit is defined by the active subscription plan. For example, if you are subscribed to the Professional plan for 100 sites and used only 60 sites by end of the subscription period, you can carry over 40 credits to next subscription period. This way you will have 40 + 100 = 140 credits for the next subscription period. In case you renew with the Professional 25 site plan, you will be able to carry over a maximum of 25 credits.
