This report highlights the best practices of photovoltaic (PV) manufacturers to protect workers and the environment during the production of solar panels. The report is divided into three sections: 1) Environmental, social, and governance considerations used by socially responsible investors and examples of how PV manufacturers are already implementing these practices; 2) Cross-platform technical opportunities; 3) Environmental health and safety risks in manufacturing particular to each technology and the best practices companies are using to mitigate these risks. Company practices were obtained as responses to a survey distributed to over 100 solar companies internationally. Best practices were determined via consultation with scientists, engineers, academics, and industry consultants.
