As the first inspection body to obtain such accreditation in Spain, TÜV Rheinland has been issuing Certificates of Conformity for photovoltaic plants and installations in compliance with the local Spanish regulation since 2011.
To guarantee the financial stability of the electricity system, a Spanish Royal Decree from 2009-2010 adopted urgent measures and implemented changes in the local energy sector, especially within the security system set up to avoid breakdowns. In support of Spanish Electricity System Security, Royal Decree RD 1565/2010 was published in November 2010, stipulating that photovoltaic plants with over 2 MW of power be required to comply with the Spanish Operational Procedure PO 12.3 in regard to voltage dips.
Power dips are short drops in voltage within an electric system. When voltage dips occur in photovoltaic installations, power drops further down the distribution stream, affecting even individual homes, may be experienced. To prevent such sudden disconnections and ensure continuity of supply, PV plants are required to comply with guidelines set out in the requirements from the Royal Decree RD 436/2004. More generally, the aim is to ensure that PV plants remain connected to the electrical system even in cases of voltage dips.

technical testing of solar components - PV
back in 1985. Our network of experts for the solar industry now comprises more than 200 specialists worldwide.
To ensure compliance with the Spanish royal requirements, it is necessary for local photovoltaic plants and installations to obtain an official Certificate of Conformity issued by an accredited body. As the first inspection body awarded this accreditation in Spain,
stood as the best-qualified partner to help many local photovoltaic plants comply with all requirements and ensure their facility reliability and continuity of operations.
As an internationally leading testing service provider for the solar industry, our experts offer certification services both for PV installations and components. Energy audits are also conducted, in accordance with Spanish Electricity System Security, to ensure compliance with all imposed regulations and decrees. Upon completion of the audit, we can provide the Certificate of Conformity.
