Central-station applications: System and subsystem research activities

The results of a number of photovoltaic central power-station studies are summarized. Analysis based upon vendor quotes and construction contractor bids indicate that $50/m2 for area related costs for flat-plate arrays is achievable. Electrical design tradeoffs for multimegawatt systems are considered. The values of photovoltaic central-station plants for various regions are determined from an energy scenario effects study.

Photovoltaic systems perspective

This paper summarizes the elements of photovoltaic power system and clarifies the terminology currently used. The relationship of system efficiency and cost is described particularly for the Balance of Photovoltaic System (BOPS) area. The current status of the BOPS development activity is described. The photovoltaic systems terminology is found to be on the road to standardization. Power conditioning, energy storage, and support structure are found to be BOPS cost and/or efficiency drivers. Although the current BOPS activity has identified low-cost/high-efficiency components, further development work is necessary.

A summary of systems definition project activities

Design information and subsystem requirement definition to the overall program is presented. Application analysis and conceptual design for the wide variety of systems, system tradeoff studies and engineering design for the more promising application types, and the identification of the technology status and requirements for major subsystems and components are described. The residential design and analysis contracts, hybrid photovoltaic/solar thermal electric conversion contract, and development of prototype combined photovoltaic/thermal flat-plate collectors were studied.
