Assurance Process

Members within the Solar Stewardship Initiative (SSI) commit to meeting the comprehensive requirements of the SSI Standards.

Each site undergoes a rigorous site-level assessment process to ensure the site meets all requirements of the Standards.

The assessment is completed by an independent Assessment Body (AB) which is approved by the SSI. Qualified independent assessors associated with approved ABs will verify a site’s compliance. After the assessment completion, a summary of the assessment activities, methodology, and results are published. 

Each site is re-assessed every three years. Detailed expectations and timelines are defined in the SSI Assurance Manual, which can be downloaded through the form below.
