Certified Sites

Prospective SSI-certified sites undergo a rigorous assessment process to ensure the site meets all requirements of the SSI Standards.

Assessments are completed by a qualified, third-party, and independent Assessment Body. After the assessment is completed, a summary of the results is published. Each site is re-assessed every three years. Detailed expectations and timelines are defined in the SSI Assurance Manual.

The table below provides a summary of SSI member sites that have received certification against SSI Standards.

Please note that the certification applies only to the named sites, not relevant companies or their supply chains. For more information please refer to the SSI Claims Guide.

The SSI ESG assessment is based on the ESG Standard and each site performance is evaluated against 96 criteria, structured across three core dimensions: 23 criteria for Governance and Business Ethics, 21 criteria for Environmental performance, and 52 criteria for Human and Labour Rights. It is important to note that some criteria may not apply to the specific site under assessment, depending on its unique context and operations.

The table below presents a list of sites that were previously certified under the Solar Stewardship Initiative but where the organisation has either left the SSI and/or decided not to renew its certification. The information is provided for reference purposes only. Certification for these sites is no longer valid.
