What is MCS Certification?

Microgeneration Certification Scheme — a UK quality standard for renewable energy installations and installers.

Quick Answer

While MCS is a UK certification, many solar products installed in Ireland carry MCS certification alongside other standards. In Ireland, the equivalent quality assurance comes through SEAI registration — all installers must be on the SEAI register to access grant schemes, which requires proof of training, insurance, and compliance with Irish Standards (IS EN 62446).

MCS Certification Explained

MCS (Microgeneration Certification Scheme) is a quality assurance scheme for small-scale renewable energy technologies in the UK. It certifies both products (solar panels, inverters) and installers, ensuring they meet defined standards for performance and safety. While MCS is a UK scheme, MCS-certified products are widely used internationally, and the certification is recognised as a mark of quality.

How Does MCS Certification Work in Ireland?

While MCS is a UK certification, many solar products installed in Ireland carry MCS certification alongside other standards. In Ireland, the equivalent quality assurance comes through SEAI registration — all installers must be on the SEAI register to access grant schemes, which requires proof of training, insurance, and compliance with Irish Standards (IS EN 62446).
