Potential enviornmental, health, and safety (E,H and S) concerns associated with all phases of the photovoltaic (PV) energy system life cycle are identified and assessed. E,H and S concerns affecting the achievement of National PV Program goals or the viability of specific PV technologies are emphasized. The report is limited to near-term manufacturing process alternatives for crystalline silicon PV materials, addresses flat-plate and concentrator collector designs, and reviews system deployment in grid-connected, roof-mounted, residential and ground-mounted central-station applications. The PV life-cycle phases examined include silicon refinement and manufacture of PV collectors, system deployment, and decommissioning. The primary E,H and S concerns that arise during collector fabrication are associated with occupational exposure to materials of undetermined toxicity or to materials that are known to be hazardous, but for which process control technology may be inadequate. Stricter exposure standards are anticipated for some materials and may indicate a need for further control technology development. Minimizing electric shock hazards is a significant concern during system construction, operation and maintenance, and decommissioning.
