Aim

To upgrade the skills and knowledge of persons in the Renewable Energy Industry to SEI Certification Level.

To provide the required level of knowledge to persons entering the Renewable Energy Industry without Certification.

Objectives

The programme will provide an extensive insight into Solar Water Heating Systmes and will prepare candidates for end of programme examinations leading to recommendation to FETAC for certification and subsequent Registration with Sustainable Energy Ireland as a Qualified Installer.
