The Electrical Certificate (CIE) for Solar Installations in Spain
If you are installing solar panels in Spain, the CIE is not optional — it is a legal requirement for any grid-connected system, regardless of size.
This page explains what the solar CIE covers, how it fits into the registration process, and what you need to budget for.

Frequently Asked Questions
Does off-grid solar need a CIE?
No. A CIE is only required for installations connected to the grid. Off-grid systems with no connection to the distribution network fall outside the scope of the CIE requirement.
Can Uswitch handle the RAIPRE registration?
Yes. As part of our solar installation service, we manage the complete registration process including the CIE, RAIPRE, and distributor formalities.
What happens if my solar system was installed without a CIE?
Systems installed without a CIE cannot be formally registered. This means you cannot access subsidy schemes and the distributor may require regularisation before accepting the installation. If this applies to you, contact us and we will arrange a retroactive inspection.
