A Comparison of Predicted to Measured Photovoltaic Module Performance

June 27, 2007
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Computer simulation models to accurately predict the electrical performance of photovoltaic modules are essential. Without such models, potential purchasers of photovoltaic systems have insufficient information to judge the relative merits and cost

Author(s)
Arthur H. Fanney, Mark W. Davis, Brian P. Dougherty, D L. King, W E. Boyson, J A. Kratochvil
Computer simulation tools used to predict the energy production of photovoltaic systems are needed in order to make informed economic decisions. These tools require input parameters that characterize module performance under various operational and

Measured Performance of Building Inegrated Photovoltaic Panels - Round 2

August 1, 2005
Author(s)
Brian P. Dougherty, Arthur H. Fanney, Mark W. Davis
Architects, building designers, and building owners presently lack sufficient resources for thoroughly evaluating the economic impact of building integrated photovoltaics (BIPV). The National Institute of Standards and Technology (NIST) is addressing this

Parameter Affecting the Performance of a Residential-Scale Stationary Fuel Cell System

May 23, 2005
Author(s)
Mark W. Davis, Arthur H. Fanney, Michael J. LaBarre, K R. Henderson, Brian P. Dougherty
Researchers at the National Institute of Standards and Technology (NIST) have measured the performance of a residential fuel cell system when subjected to various environmental and load conditions. The system, which uses natural gas as its source fuel, is

Measured Versus Predicted Performance of Building Integrated Photovoltics

February 1, 2003
Author(s)
Mark W. Davis, Arthur H. Fanney, Brian P. Dougherty
The lack of predictive performance tools creates a barrier to the widespread use of building integrated photovoltaic panels. The National Institute of Standards and Technology (NIST) has created a building integrated photovoltaic (BIPV) test bed to capture

Short-Term Characterization of Building Integrated Photovoltaic Panels

February 1, 2003
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Building integrated photovoltaics, the integration of photovoltaic cells into one or more exterior building surfaces, represents a small but growing part of today s $2 billion photovoltaic industry. A barrier to the widespread use of building integrated

The lack of predictive performance tools creates a barrier to the widespread use of building integrated photovoltaic panels. The National Institute of Standards and Technology has created a building integrated photovoltaic (BIPV) test bed to capture

Evaluating Building Integrated Photovoltaic Performance Models

May 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Predictive performance tools could accelerate the implementation of integrated photovoltaics (BIPV. The National Institute of Standards and Technology (NIST) seeks to improve and validate previously developed computer simulation tools with experimental

Performance and Characterization of Building Integrated Photovoltaic Panels

May 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Buildings consume more than two-thirds of the electricity in the United States. The incorporation of photovoltaics into the buildings, referred to as building integrated photovoltaics (BIPV), offers an aesthetically pleasing means of displacing centrally

Field Test of a Photovoltaic Water Heater

January 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, J O. Richardson
A solar photovoltaic water heating system has been installed at the Great Smoky Mountains National Park. The system provides hot water for the restroom facilities at the Park's main visitor center. This paper gives an overview of the technology, describes

Building Integrated Photovoltaic Test Facility

August 1, 2001
Author(s)
Arthur H. Fanney, Brian P. Dougherty
The widespread use of building integrated photovoltaics appears likely as a result of the continuing decline in photovoltaic manufacturing costs, the relative ease in which photovoltaics can be incorporated within the building envelope, and the fact that
