SSI Standards

At the Solar Stewardship Initiative (SSI), we are setting standards for responsible solar production, sourcing, and stewardship.

SSI ESG Standard

The SSI aims to create a more responsible, transparent, and sustainable solar value chain. With the solar sector’s rapid growth, we’re focused on maximising its positive impact while respecting human rights and fostering a just and inclusive energy transition.

The SSI ESG Standard is designed to evaluate a production site’s performance in three key areas:

  • Governance and Business Ethics
  • Environment
  • Human and Labour Rights.

These are critical considerations for industries where ethical sourcing is paramount.

SSI Supply Chain Traceability Standard (under development)

As the solar sector continues to expand, the SSI is committed to ensuring that this growth is ethical and sustainable.

The SSI Traceability Standard is a cornerstone of our efforts, ensuring the solar value chain remains ethical. This standard’s primary goal is to track and trace the movement of goods, materials, and information at each stage of the supply chain, from the source of raw materials to the end consumer.

Using the Traceability Standard and the ESG Standard together will make product certification possible.

To assist with implementing SSI Standards and frameworks, we provide the following supporting documents:

SSI ESG Standard

This standard will cover all the requirements needed to address environmental, social and governance sustainability for sites engaged in manufacturing polysilicon, ingots, wafers, cells and modules, and other components.

SSI Assurance Manual

A manual on processes that apply when preparing for an assessment against the SSI Standard, verifying conformance of a site against the requirements of the SSI Standard, certification decisions and issuing certificates based on recommendations from independent and approved third-party Assessment Bodies, and activities to be carried out after initial certification.
