About SSI

The Solar Stewardship Initiative (SSI) is the first-ever supply chain sustainability assurance scheme dedicated to the needs of the solar PV sector and its customers.

The Initiative establishes SSI Standards, combining international standards, industry and civil society expertise, and political acumen, to deliver a supply chain sustainability solution tailored to the business of solar.

The SSI Standards are used by independent assessors to evaluate compliance with robust sustainability and Environmental, Social and Governance (ESG) criteria within companies active in the solar value chain.

The SSI was set in motion by SolarPower Europe and Solar Energy UK in March 2021, as part of a workstream established in 2015 to promote sustainable production in the solar value chain.

With the backing over 30 solar organisations at its inception, the SSI is the only holistic sustainable supply chain solution with the support of a majority market share of the solar PV industry.

The SSI also enjoys the endorsement of the International Finance Corporation (IFC, a member of the World Bank Group) and the European Investment Bank (EIB).

SSI Transitional Governance

(2023-2024)

Currently, the SSI is governed by the SSI Board and Stakeholder Advisory Group (SAG).

The SSI Board, appointed for two years, is the primary decision-making body. Comprising of associations and industry representatives initially, it will evolve into a multi-stakeholder Board later in 2024. Industry representatives of the first Board appointed in November 2023 will be drawn from the founding members of the SSI.

The Stakeholder Advisory Group (SAG), an integral part of SSI Governance, will represent diverse perspectives from civil society, academia, independent experts, and other relevant non-industry stakeholders. SAG members will advise the SSI Board on various aspects, ensuring a holistic approach to decision-making.

Various SSI working groups and committees will be established to facilitate targeted discussions and actions in line with our mission. For example, new Standards, such as the SSI Supply Chain Traceability Standard, will be developed in working groups.
